Detailed ways

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

Fig. 1 shows a flowchart of a method for maintaining the operation of a network application platform according to an embodiment of the present invention. In this embodiment, the network application platform communicates with one or more underlying servers, and each underlying server provides one or more applications to the network application platform. The network application platform includes an application portal, in which all applications provided by all underlying servers are presented, for different users to access interested applications according to their own needs. Here, the network application platform can be realized by one or more servers, and the application portal can be, for example, an application interface set on the network application platform.

As shown in FIG. 1 , the method for maintaining the operation of a network application platform according to an embodiment of the present invention starts at step S110 , and in step S110 , it is detected whether the application provided in each underlying server is normal.

In order to prevent the failure of a certain underlying server from affecting the normal operation of the network application platform and other underlying servers, the state of the application provided in each underlying server can be detected. Specifically, it is possible to check whether the applications provided in each underlying server are normal at a preset time interval. In order to detect faults in time, the preset time interval can be set as small as possible to achieve an approximate real-time detection effect.

Wherein, the user accesses the application provided by the underlying server through a predetermined URL corresponding to the application provided by the underlying server. That is to say, each application has a corresponding URL, and the application can be accessed by visiting the URL. Therefore, when detecting whether an application provided by a certain underlying server is normal, the detection may be performed by accessing a URL corresponding to the application provided by the underlying server. If the underlying server does not respond to the URL request or generates an error when accessing the URL corresponding to the application provided by the underlying server, it is determined that the application corresponding to the URL is abnormal; otherwise, it is determined that the application corresponding to the URL is normal . For example, a URL corresponding to an application provided by an underlying server may be accessed through a shell script (or other scripts). If the underlying server does not respond to the URL request within a predetermined time, or generates an error message, for example, if the underlying If the server returns an HTTP error code such as 500 or 502, it is determined that the application corresponding to the URL is abnormal. Here, 500 indicates internal server error information, and 502 indicates gateway error information. According to the generated error information, the cause of the failure of the application in the underlying server can be preliminarily determined. By regularly accessing the URL corresponding to each application in each underlying server, it can be determined whether the status of each application in each underlying server is normal.

In addition, in order to ensure the timely repair of the underlying server, after determining that the status of an application in a certain underlying server is abnormal, a short message notification can be sent to the technician, so that the technician can repair it in time.

After the detection results of the applications provided by each underlying server are obtained in the above step S110, in step S120, the applications whose detection results are normal are loaded in the application portal, and the abnormal applications are not loaded. That is to say, in step S120, it is determined which applications should be loaded in the application portal according to the detection result obtained in step S110.

Specifically, in step S120, which applications are loaded in the application portal can be realized by the script of the application portal. An implementation manner of the script of the application portal is: only include parameter information corresponding to the application to be loaded, and not include parameter information corresponding to the application not to be loaded. In this way, the user can only see normal applications and call them through the application portal, but cannot see abnormal applications at all, so there will be no faults caused by calling abnormal applications. In addition, since the loaded applications and non-loaded applications determined according to the detection results may change, it is necessary to release a new version of the script of the application portal, which only includes the corresponding applications whose detection results are normal. The parameter information does not include the parameter information corresponding to the abnormal application, so that by running the new version of the script of the application portal, all the applications displayed to the user on the network application platform will be applications that can run normally.

Another way to realize the script of the application portal is to include parameter information corresponding to all applications, but, for each application, it also includes a parameter used to determine whether the application is displayed, when the parameter value of the parameter is 1 , indicating that the application can be presented to the user, so that when the new version of the application portal script is run, the application is loaded; when the parameter value of this parameter is 0, it indicates that the application is not presented to the user, when the application portal script is run The app is not loaded when the new version is installed. Therefore, the application portal determines whether to load the corresponding application according to the parameter value of the parameter determining whether the application is presented in the script. In this implementation, in order to present the applications loaded according to the detection results, a new version of the script of the application portal needs to be released. In this new version, for applications whose detection results are normal, the corresponding decision whether to display If the parameter value of the parameter is set to 1, the application will be loaded when running the new version of the script of the application portal, so it will be presented to the user; for the application whose detection result is abnormal, its corresponding parameter to determine whether to present If the value of the parameter is set to 0, the app will not be loaded when running a new version of the app portal's script, and thus will not be presented to the user. It can be seen from this that when running the new version of the application portal script, all the applications provided by the underlying server in a normal state are presented to the user, while the applications provided by the underlying server in an abnormal state will not be presented to the user.

According to an example of the present invention, the scripts used by the application portal may be shell scripts or other scripts.

By adopting the above-mentioned method for maintaining the operation of the network application platform provided by the present invention, even if there is an application with an abnormal state in a certain underlying server, the user can also access the application with a normal state through the application portal, thereby ensuring the normal operation of the network application platform , so that the network application platform will not fail to operate normally due to failure of one or several applications provided by one or several underlying servers.

Optionally, in order to ensure that the abnormal application can be loaded into the application portal in a timely manner when it returns to normal, the method for maintaining the operation of the network application platform of the present invention may further include step S130, in step S130, detecting the above-mentioned detected as Whether the abnormal application has returned to normal, when it is detected that it has returned to normal, the application that has returned to normal is loaded in the application portal, so as to provide users with as many applications as possible.

On the one hand, the step S130 can be executed after the step S120, that is, only further detection is performed on the abnormal application detected in the step S110, and whether it has returned to normal is detected, and when it is detected that the application has returned to normal, the application is released A new version of the app portal script that reloads a restored app into the app portal. On the other hand, the step S130 may also be executed after the step S110, that is, after the step of detecting whether the application provided by each underlying server is normal at a preset time interval in the step S110, the step S130 is further executed, To detect whether the application that was detected as abnormal before has returned to normal, so that when step S120 is performed to release a new version of the application portal script, not only the application that has been detected as normal is loaded in the new version, but also the application that has returned to normal is reloaded. Applications, so that users can access the normal applications as soon as possible, reducing the impact on users.

Adopting step S130 can avoid the problem that an application is put aside for a long time after it is detected as abnormal, so that the user cannot access the application for a long time.

In addition, the present invention can also adopt another method: after obtaining the detection results of all underlying servers in step S110 each time, compare the detection results of this time with the detection results of the last time, if the detection results of this time are the same as those of the previous If the detection result is different once, a new version of the application portal script will be released, and the application with a normal detection result will be loaded in this new version, and the application with an abnormal detection result will not be loaded; if the detection result this time is the same as the previous detection result, Then there is no need to publish a new version of the app portal script. In this way, the update times of the network application platform can be reduced, and the running speed can be improved.

Fig. 2 shows a schematic diagram of the structure between the maintenance device for maintaining the operation of the network application platform, the network application platform and the underlying server according to an embodiment of the present invention. As shown in FIG. 2 , the maintenance device 200 includes: a monitor 210 and an application portal controller 220 . The monitor 210 is respectively connected in communication with each underlying server, and is configured to detect whether the applications in each underlying server are normal. The application portal controller 220 controls the application portal to load applications whose detection results are normal and not to load applications whose detection results are abnormal according to the detection results of the monitor 210 . In order to clearly illustrate the connection relationship between the maintenance equipment 200, the network application platform and each underlying server, in Fig. 2 not only the maintenance equipment 200 of the present invention is shown, but also the Connected web application platform 320 and underlying server 310. As shown in FIG. 2 , a network application platform 320 including an application portal 321 is respectively connected to each underlying server 310, wherein the application portal 321 loads the normal application provided in the underlying server 310 and presents it to the user. The application interface of the interface. The application portal controller 220 is connected to the application portal 321 of the network application platform 320 and the monitor 210 respectively. The monitor 210 is respectively connected with each underlying server 310 to detect whether the application provided in each underlying server 310 is normal, and transmits the detection result to the application portal controller 220, wherein the monitor 210 can detect every Whether the application provided in each underlying server 310 is normal, the specific detection method can be by accessing the URL corresponding to the application in the underlying server to be detected, if there is no response to the request of the URL corresponding to the application or an error message is returned, then determine The application corresponding to this URL is abnormal. For example, the returned error message may be http500 (indicating internal server error information) or http502 (indicating gateway error information). The application portal controller 220 controls the application portal 321 to load the application detected as normal and not to load the application detected as abnormal based on the detection result of the monitor 210 .

After obtaining the detection result, the monitor 210 sends the detection result to the application portal controller 220 . The application portal controller 220 loads an application whose detection result is normal, but does not load an application whose detection result is abnormal.

Specifically, the application portal controller 220 controls which applications to be loaded in the application portal can be implemented by scripts of the application portal. An implementation manner of the script of the application portal is: only include parameter information corresponding to the application to be loaded, and not include parameter information corresponding to the application not to be loaded. In this way, the user can only see normal applications and call them through the application portal, but cannot see abnormal applications at all, so there will be no faults caused by calling abnormal applications. In addition, since the loaded application and the non-loaded application determined according to the detection result may change, it is necessary for the application portal controller 220 to release a new version of the script of the application portal, in which only the detection The result is the parameter information corresponding to the normal application, but does not include the parameter information corresponding to the abnormal application.

Optionally, another way to realize the script of the application portal is to include parameter information corresponding to all applications, but for each application, it also includes a parameter used to determine whether the application is displayed, when the parameter of the parameter When the value is 1, it means that the application can be presented to the user. In this way, when running the new version of the application portal script, the application is loaded; when the value of this parameter is 0, it means that the application is not presented to the user. The app is not loaded when a new version of the portal script is installed. Therefore, the application portal determines whether to load the corresponding application according to the parameter value of the parameter determining whether the application is presented in the script. In this implementation, in order to present the application loaded according to the detection result, the application portal controller 220 needs to release a new version of the script of the application portal. In this new version, for the application with a normal detection result, its If the parameter value of the corresponding parameter for determining whether to present is set to 1, the application will be loaded when running the new version of the script of the application portal, and thus will be presented to the user; for applications with abnormal detection results, the corresponding decision will be made If the parameter value of the whether to present parameter is set to 0, the application will not be loaded when running the new version of the script of the application portal, and thus will not be presented to the user. It can be seen from this that when the new version of the application portal script is run, all the applications provided by the underlying server in a normal state will be presented to the user, while the applications provided by the underlying server in an abnormal state will not be presented to the user.

Wherein, the application portal controller 220 may further include an application loading module, which adopts one of the above two implementation manners of application portal scripts, and releases a new version of the application portal based on the detection result.

By adopting the above-mentioned maintenance equipment for maintaining the operation of the network application platform provided by the present invention, even if there is an application with an abnormal state in a certain underlying server, the user can also access the application with a normal state through the application portal, thereby ensuring the normal operation of the network application platform Operation, so that the network application platform will not fail to operate normally due to failure of one or several underlying servers or one or several applications provided by it.

Optionally, in order to ensure that the abnormal application can be loaded into the application portal in time when it returns to normal, in the maintenance device for maintaining the operation of the network application platform of the present invention, the monitor 210 can also be used to detect the above-mentioned detected as Whether the abnormal application has returned to normal, when it is detected that it has returned to normal, notify the application portal controller 220 to load the restored application in the application portal, so as to provide as many applications as possible for the user.

Specifically, in order to realize the loading of the normal application, the monitor 210 can further detect the above-mentioned abnormal application to detect whether it has recovered normal, and when it is detected that it has recovered normal, notify the application portal control The server 220 republishes a new version of the application portal script in which the restored application is reloaded into the application portal.

Alternatively, the application portal controller 220 may compare the current detection result with the previous detection result after obtaining the detection result of the monitor 210 each time, if the current detection result is different from the previous detection result , a new version of the application portal script is released, and applications with normal detection results are loaded in the new version, and applications with abnormal detection results are not loaded. If the detection results this time are the same as the previous detection results, there is no need to release a new version of the application portal script. In this way, the update times of the network application platform can be reduced, and the running speed can be improved.

In the above process, the monitor 210 and the application portal controller 220 may communicate through a special application program interface API. For example, an API may be set on the application portal controller 220 to receive the detection result from the monitor 210, and the monitor 210 sends the detection result to the application portal controller 220 through the API. Through the API communication method, the communication efficiency can be improved.

FIG. 3 and FIG. 4 respectively show the interface diagrams presented to the user by the network application platform before and after detecting an abnormality of a certain underlying server in the embodiment of the present invention. Here, Fig. 3 and Fig. 4 are described by taking an online game platform providing games as an example. As shown in Figure 3, under normal conditions, the game interface presents the status of applications provided by the four underlying servers, that is, the user login part: it presents the user's username or current location, and in this part, the user can " "Change password" or "Change account"; "New area opening" part: it presents the name of the area server of the newly opened game on the website to the user, for example, as shown in Figure 3, "360 Guardian 07 area" is a newly opened game area server; "All Servers" section: It presents to the user the names of all regional servers that provide game services that are currently available normally. For example, Figure 3 shows the seven regional servers that can currently provide services normally "360 Guardian 01 Area"~"" 360 Guardian 07 Area", the user can click on any area server to invoke the game provided by it; the "logged in server" part: it presents the user with the names of all area servers that the user has logged in, for example, Figure 3 shows the user The user named "Tribal Boss" has logged into "360 Guard 04", "360 Guard 05", and "360 Guard 03", and the top one is the most recently logged-in server.

When an abnormality is detected in the underlying server used to manage the "logged-in server", the application portal of the online game platform will release a new version, and the new version does not load the "logged-in server" function. For applications provided by a functional underlying server, at this time, the "logged-in server" part of the interface presented to the user by the online game platform does not present any content, as shown in Figure 4, while for other normally operating underlying servers, It can still be normally displayed in the interface presented to the user by the online game platform in Figure 4, so that the online game platform will not be unable to work normally due to an abnormality in a certain underlying server, and other underlying servers will not be abnormal due to this The underlying server cannot operate normally, thus ensuring the continuity of services provided by the online game platform to users.

Through the method for maintaining the operation of the network application platform and the maintenance equipment of the present invention, it is possible to detect whether the applications provided in each underlying server are normal, and to load normal applications in the application portal according to the detection results, and not to load abnormal applications. This solves the problem that as long as an application in one underlying server fails, it will affect the operation of the entire application portal. In the event of an application failure in a certain underlying server, the application portal can still provide users with applications from other underlying servers .
