Description
Technical Field
The invention belongs to the technical field of computers, and particularly relates to a fragment data caching and accessing method, a fragment data caching and accessing device, a fragment data caching and accessing terminal and a fragment data storage medium.
Background
The Hypertext Transfer Protocol (HTTP) is a simple request-response Protocol, which is a Transfer Protocol for a server to Transfer Hypertext to a client (e.g., a browser). The caching mechanism of the HTTP is a technical means capable of improving the multiplexing rate of the client to the server data, reducing the number of requests, and improving the access experience, and has been widely applied to a software system with HTTP requests.
According to whether an HTTP request needs to be sent to a server or not, the caching process is divided into two parts, namely strong caching and negotiation caching. Specifically, when a client requests a server for a network resource, a message header (header) information of the resource cache is acquired first, whether the strong cache is hit is judged according to cache control (cache-control) and effective time (expires) information in the message header, and if the strong cache is hit, the resource information is directly acquired from the cache and includes cache message header information, and the resource request cannot be communicated with the server. If the strong cache is not hit, the client sends a request to the server, the request carries the first returned information of the message header field related to the cache, and the server compares the result according to the information of the message header to judge whether the cache is hit or not. If the resource content is hit, the server returns new response message header information to update the corresponding message header information in the cache, but the requested resource content is not returned, the returned new response message header information tells the client that the new response message header information can be directly obtained from the cache, otherwise, the latest resource content is returned.
However, the caching scheme of the existing HTTP protocol does not support Range request, that is, a designated file or partial data of data returned by the server cannot be cached, and fragmented data (a piece of data) returned by the server is not cached at the client. Thus, the client still needs to go back to the server for downloading when the same Range request is made next time.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The following detailed description of specific implementations of the present invention is provided in conjunction with specific embodiments:
the first embodiment is as follows:
fig. 1 shows an implementation flow of a fragment data caching method according to an embodiment of the present invention, and for convenience of description, only parts related to the embodiment of the present invention are shown, which are detailed as follows:
in step S101, an HTTP request requesting access to the designated fragmented data is received;
the embodiment of the invention is suitable for computing equipment, in particular to a client in a client/server (C/S) mode, wherein the client is connected with a server through a network, receives a request of a user, sends an HTTP request to the server through the network and operates (accesses) a target file. In this embodiment of the present invention, the HTTP request is a request for operating specified fragmented data of the target file, where the specified fragmented data is a part of the target file stored on the server, that is, requests to access data in a specified Range in the target file on the server, and specifically, the specified Range is specified by a request Range (e.g., a Range parameter) in a header of the HTTP request.
In step S102, obtaining parameter values of preset request parameters from the HTTP request, where the request parameters include a request address, a request method, and a request range;
in the embodiment of the invention, after the client receives the HTTP request of the user, the parameter value of the preset request parameter is obtained from the HTTP request, and the request parameter comprises the request address, the request method and the request range, so that the request parameter settings of different request methods in the HTTP request are unified, and the response efficiency of the HTTP request is improved.
In the request parameters of the HTTP request, the request address is an address, for example, a URL (Uniform Resource Locator) address, of a Resource or data (target file) to be requested to access, the request method specifies what operation the client wants to perform on the target file on the server, and the request scope specifies a scope of the target file to be requested to operate or access, that is, a location of the fragmented data in the target file. Preferably, the request method includes a GET method and a HEAD method, so that the fragment data obtained by the GET method is cached in the following, and response efficiency when the fragment data is accessed again is improved. In addition, the request header information of the HTTP request can be acquired through the HEAD method, and the validity of the resource or the hyperlink can be detected through caching the request header information. Here, in order to unify the request parameter settings of different request methods in the HTTP request, when the request method in the HTTP request is the HEAD method, the range of the request range may be set to a range in which a start value and an end value are the same, such as 0 to 0, so as to simplify the parameter configuration when the request method is the HEAD method, and improve the access efficiency of the subsequent cache.
In step S103, a preset cache information list is obtained according to the request address, and cache information of the designated fragment data in the cache information list is searched according to the request method and the request range;
the embodiment of the invention sets a cache information list at the client for recording the cache information of the fragment data at the client, and the cache information list can be any table, file and the like capable of recording the cache information. Specifically, the cache information list may include a plurality of cache information items, each cache information item may correspond to cache information of one piece of fragmented data, and the cache information item may include a request address, a request method, and request range parameter information in an HTPP request responded by the server, and may further include a cache address of the fragmented data at the client. Preferably, the method may further include obtaining an identification number through operation of the request address and the request method, so as to quickly find the corresponding cache information item through the identification number, and further finally determine whether the requested fragment data is cached through the request range parameter.
Specifically, when the cache information of the designated fragment data in the cache information list is searched, the cache information list corresponding to the request address is first obtained, and when the cache information list corresponding to the request address is not obtained, it is determined that the cache information is not searched. And when the cache information list corresponding to the request address is acquired, matching the request method in the acquired cache information list, and when the request method is not matched, determining that the cache information is not found. And when the request method is matched, acquiring the corresponding cache information item, and searching the cache information item corresponding to the request range in the HTTP request in the acquired cache information item. When the cache information item corresponding to the request range in the HTTP request is searched for in the obtained cache information item, specifically, a start value and an end value of the request range in the HTTP request may be compared with a start value and an end value of the request range in the cache information item, when the start value of the request range in the HTTP request is greater than or equal to the start value of the request range in the cache information item and the end value is less than or equal to the end value of the request range in the cache information item, it is determined that the corresponding cache information item is searched for, otherwise, it is determined that the corresponding cache information item is not searched for. When the cache information item is not found, determining that the cache information is not found, and quickly positioning the cache information of the designated fragment data in the client cache information list according to the request address, the request method and the request range in the HTTP request.
In step S104, when the cache information is not found, sending an HTTP request to the server, receiving a response from the server to the HTTP request, and storing the response in a preset storage unit;
in the embodiment of the invention, when the cache information of the specified fragment data at the client is not found, the client sends an HTTP request to the server, the server obtains a target file requested to be accessed by the client according to a request address in the HTTP request after receiving the HTTP request, then executes a corresponding request method for the specified fragment data in a corresponding range of the target file according to a request range, and then returns a corresponding response to the client. And the client receives the response to the HTTP request returned by the server and stores the response to a preset storage unit of the client. Specifically, when the response data is stored in a preset storage unit, for example, when the request method in the HTTP request is the GET method, the requested data may be stored, and when the request method in the HTTP request is the HEAD method, only the response header information of the request is stored.
In step S105, generating cache information corresponding to a response according to the address information of the storage unit and the request parameter;
after the response of the server is stored in the storage unit of the client, the client generates cache information corresponding to the response according to the address information of the storage unit and the request parameter in the HTTP request.
Specifically, when the cache information corresponding to the response is generated, the request address, the request method, and the request range parameter information in the HTPP request may be set in the cache information, and the cache address of the fragmented data at the client may also be set in the cache information. Preferably, when the cache information is generated, an identification number is obtained through operation of a request address and a request method, and the identification number is added to the cache information, so that the cache information can be searched quickly through the identification number in the following process, and the cache (fragmented data) is finally positioned through a request range. Of course, when the cache information is generated, the information such as the validity period of the cache may also be set.
In step S106, the cache information corresponding to the response is added to the cache information list.
After the cache information corresponding to the response is added to the cache information list, the cache information becomes a cache information item in the cache information list, and subsequently, when an HTTP request requesting to access the same fragmented data is received, the list can be acquired to acquire the cached fragmented data.
When an HTTP request for requesting to access specified fragment data is received, the embodiment of the invention acquires parameter values comprising a request address, a request method and a request range parameter from the HTTP request, obtaining a preset cache information list according to the request address, searching the cache information of the appointed fragment data in the cache information list according to the request method and the request range, when the cache information is not found, sending an HTTP request to the server, receiving the response of the server to the HTTP request, storing the response to a preset storage unit, generating cache information corresponding to the response according to the address information of the storage unit and the request parameter, and finally adding the cache information corresponding to the response into a cache information list, thereby not needing to change the server, the cache of the fragment data can be realized, and the access efficiency is improved when the subsequent user accesses the fragment data.
Example two:
fig. 2 shows an implementation flow of the method for accessing fragmented data according to the second embodiment of the present invention, and for convenience of description, only the parts related to the second embodiment of the present invention are shown, which are detailed as follows:
in step S201, an HTTP request requesting access to the designated fragmented data is received;
the embodiment of the invention is suitable for computing equipment, in particular to a client in a client/server (C/S) mode, wherein the client is connected with a server through a network, receives a request of a user, sends an HTTP request to the server through the network and operates (accesses) a target file. In this embodiment of the present invention, the HTTP request is an HTTP request for operating specified fragment data of the target file, where the specified fragment data is a part of the target file stored on the server, that is, requests to access data in a specified Range in the target file on the server, and specifically, the specified Range is specified by a request Range (for example, a Range parameter) in a header of the HTTP request.
In step S202, parameter values of preset request parameters are obtained from the HTTP request, where the request parameters include a request address, a request method, and a request range;
in the embodiment of the invention, after the client receives the HTTP request of the user, the parameter value of the preset request parameter is obtained from the HTTP request, and the request parameter comprises the request address, the request method and the request range, so that the request parameter settings of different request methods in the HTTP request are unified, and the response efficiency of the HTTP request is improved.
In the request parameters of the HTTP request, the request address is an address of a request for accessing a resource or data (a target file), the request method specifies what operation the client wants to perform on the target file on the server, and the request range specifies a range of the target file requested to operate or access, that is, a position of the fragmented data in the target file. Preferably, the request method includes a GET method and a HEAD method, so that the fragment data obtained by the GET method is cached in the following, and response efficiency when the fragment data is accessed again is improved. In addition, the request header information of the HTTP request can be acquired through the HEAD method, and the validity or accessibility of the resource or the hyperlink can be detected through caching the request header information. Here, in order to unify the request parameter settings of different request methods in the HTTP request, when the request method in the HTTP request is the HEAD method, the range of the request range may be set to a range in which a start value and an end value are the same, such as 0 to 0, so as to simplify the parameter configuration when the request method is the HEAD method, and improve the access efficiency of the subsequent cache.
In step S203, a preset cache information list is obtained according to the request address, and cache information of the designated fragment data in the cache information list is searched according to the request method and the request range;
the embodiment of the invention sets a cache information list at the client for recording the cache information of the fragment data at the client, and the cache information list can be any table, file and the like capable of recording the cache information. Specifically, the cache information list may include a plurality of cache information items, each cache information item may correspond to cache information of one piece of fragmented data, and the cache information item may include a request address, a request method, and request range parameter information in an HTPP request responded by the server, and may further include a cache address of the fragmented data at the client. Preferably, the method may further include obtaining an identification number through operation of the request address and the request method, so as to quickly find the corresponding cache information item through the identification number, and further finally determine whether the requested fragment data is cached through the request range parameter.
Specifically, when searching for the cache information of the designated fragment data in the cache information list, firstly, according to the request address in the HTTP request, obtaining the cache information list corresponding to the request address, matching the request method in the obtained cache information list, when the request method is matched in the cache information list, obtaining the corresponding cache information item, searching for the cache information item corresponding to the request range in the HTTP request in the obtained cache information item, when the request is found, obtaining the cache information in the searched cache information item, and determining the obtained cache information as the cache information of the designated fragment data in the cache information list, thereby quickly locating the cache information of the designated fragment data in the client cache information list according to the request address, the request method, and the request range in the HTTP request. When the cache information item corresponding to the request range in the HTTP request is searched for in the obtained cache information item, specifically, a start value and an end value of the request range in the HTTP request may be compared with a start value and an end value of the request range in the cache information item, and when the start value of the request range in the HTTP request is greater than or equal to the start value of the request range in the cache information item and the end value is less than or equal to the end value of the request range in the cache information item, it is determined that the cache information item is the cache information corresponding to the designated fragment data.
In step S204, when the cache information is found, the cached designated fragment data is obtained according to the cache information.
In the embodiment of the invention, after the cache information is found, the address information of the storage unit for storing the specified fragment data is obtained from the cache information, and the cached specified fragment data is read according to the address information. Specifically, when the start value of the request range in the HTTP request is greater than the start value of the request range in the cache information item and the end value is less than the end value of the request range in the cache information item, it indicates that the cached data covers the fragmented data that the user wants to access, at this time, the cache data corresponding to the cache information item is obtained, and the fragmented data corresponding to the request range in the HTTP request is intercepted from the obtained cache data according to the request range (i.e., the start value and the end value of the request range) in the HTTP request, so as to accurately obtain the cached specified fragmented data.
Further, after the fragment data corresponding to the request range in the HTTP request is intercepted, the fragment data may be stored in a storage unit (cache memory) of the client, cache information corresponding to the fragment data is generated according to the address information of the storage unit and the request parameter in the HTTP request, and then the generated cache information is added to a cache information list, so that the latest accessed fragment data of the user is cached, and the hit rate of subsequent caches is improved.
According to the embodiment of the invention, when an HTTP request requesting to access the designated fragment data is received, parameter values including a request address, a request method and a request range parameter are obtained from the HTTP request, a preset cache information list is obtained according to the request address, cache information of the designated fragment data in the cache information list is searched according to the request method and the request range, and when the cache information is searched, the cached designated fragment data is obtained according to the cache information, so that the cached fragment data is used for responding to the fragment data request of a user, the fragment data request is not required to be obtained from a server, and the access efficiency of the fragment data is improved.
