Description

A method and device for pushing information

technical field

The present invention relates to the field of computer technology, in particular to an information push method and device.

Background technique

Although the Internet has only been popularized for more than ten years from its emerging to the present, it has undergone many changes in the development of browsers. Today's browsers and web pages have many new functions and new technologies that are unprecedented, and different browsers have different functions. Information push has a large number of application directions in the industry, and it is a very hot technical direction of the Internet today.

At present, server push technology (Server Push) can push data directly from the server to the client, so as to provide users with the latest information according to their preferences. In one prior art, the server may implement pushing based on an iframe.

The method based on iframe (HTML tag) is to create a nested page containing another document through the iframe to display the content, that is, to embed another webpage in the webpage. The iframe-based push generally has a hidden iframe in the page requesting push information. The source src of the iframe is a server-side application servlet that maintains a long connection to the server. This servlet will pass the content to be pushed as a parameter to home page. This method has the following disadvantages:

1) When the push service is required, it is necessary to request the push page every time, because the push page includes pictures, etc., so that each request to push the page wastes a lot of bandwidth;

2) When it is necessary to recreate a complete page, the development is difficult and the cycle is long;

3) The technical requirements for the party responsible for pushing information are relatively high. Since the iframe method is to embed one webpage into another webpage, the party responsible for pushing information needs to maintain a complete page in addition to developing the page;

4) It is easy to cause user page errors or even security issues. If the embedded page has error codes or fills in destructive codes, it will cause abnormal display on the user end or even security issues.

An embodiment of the present invention provides an information push method, and FIG. 1 shows a method flowchart of the information push method, including:

S101. Obtain the JSON file from the information provider of the current user page.

In the embodiment of the present invention, the JSON file is pre-generated by the information provider and has a standard format. The JSON file includes text, picture links, details page links, and the like.

Among them, JSON is the abbreviation of JavaScript Object Notation, which is a lightweight data exchange format, which is easy to read and portable, and also easy to be parsed and generated by machines.

S102. Generate an identifier of the JSON file according to the JSON file.

Optionally, the hash algorithm used in the embodiment of the present invention may be SHA-1 (Secure Hash Algorithm) or MD5 (Message-Digest Algorithm5), which is not limited in the present invention. Correspondingly, if the MD5 information digest algorithm is used, the generated identifier is the MD5 information digest of the JSON file, and if the SHA-1 secure hash algorithm is used, the generated identifier is the SHA1 value.

S103. Write the JSON file and the identifier of the JSON file into the template file to generate the data of the update page; wherein, the URL of the update page is the same as the URL of the current user page.

For example, the template file above can be a pre-set Hypertext Markup Language HTML element, including Cascading Style Sheet (CSS, Cascading Style Sheet), JavaScript (JS for short), etc.; fill the JSON file and its identifier into the vacant HTML element In the future, the data for updating the page can be formed. for example:

In the template, the color of a certain font is: font color: "a"; the identifier of the JSON file is: jsonid: "b".

In the JSON file, there is a corresponding field displayed as: a=blue.

Assume that the identifier of the generated JSON file is json1, namely: b=json1.

S104. Match the identifier of the JSON file in the data of the updated page with the identifier of the data of the current user page, if the identifier of the data of the current user page is different from the identifier of the JSON file in the data of the updated page, Push the data of the updated page to the user.

For example, the data of the current user page is replaced with the data of the updated page, and an update reminder is triggered.

In an embodiment of the present invention, the identifier in the data of the current user page may be an identifier in pre-acquired user page data, for example, may be an identifier recorded when the page data was pushed to the user last time.

Wherein, the update reminder may add a dot-shaped small icon on the user page logo, as shown in FIG. 2 , or remind in other ways, which is not limited in the present invention.

Optionally, if the identifier in the data of the current user page is the same as the identifier of the JSON file in the data of the updated page, the data of the updated page is discarded.

By adopting the technical scheme of the present invention, it is possible to avoid page abnormalities caused by filling errors in data sources or page scaling, and at the same time avoid network performance waste caused by continuous acquisition and update of data.

Optionally, in an embodiment of the present invention, after the above (S101) obtaining the JSON file, it may also include:

S105. Perform format verification on the JSON file. If the format verification error occurs, the file is discarded; otherwise, S102 is executed.

Wherein, the format check can be realized by a regular expression, and can also be realized by other methods, which is not limited in the present invention.

In the embodiment of the present invention, by adopting the format verification method, the abnormal display on the user terminal that may be caused by the error in filling in the JSON file by the information provider is avoided.

The embodiment of the present invention also provides an information push device. Figure 3 shows a schematic structural diagram of the information push device, which specifically includes:

Obtaining module 201, for obtaining the JSON file from the information provider of the current user page;

The identification generating module 202 is configured to generate the identification of the JSON file according to the JSON file.

Wherein, the identifier of the JSON file can be generated by using the MD5 information digest algorithm or the SHA-1 encrypted hash algorithm. Correspondingly, if the MD5 information digest algorithm is used, the generated identifier is the MD5 information digest of the JSON file, and if the SHA-1 secure hash algorithm is used, the generated identifier is the SHA1 value.

The page generating module 203 is configured to write the JSON file and the identifier of the JSON file into the template file to generate data of an updated page; wherein, the URL of the updated page is the same as the URL of the current user page.

The push module 204 is configured to match the identifier of the JSON file in the data of the update page with the identifier of the data of the current user page, if the identifier of the data of the current user page is the same as that of the JSON file in the data of the update page The identifiers are different, and the data of the updated page is pushed to the user.

By adopting the technical scheme of the present invention, it is possible to avoid page abnormalities caused by filling errors in data sources or page scaling, and at the same time avoid network performance waste caused by continuous acquisition and update of data.

Optionally, the information push device provided in the embodiment of the present invention may also include:

The format check module 205 is used to check the format of the JSON file obtained by the acquisition module 201; if the check is passed, the trigger identification generation module 202;
