Abstract

The invention provides a data interaction method of a Web management system based on Json data protocols. The data interaction method comprises the steps that a Web information sending request is received, wherein the Web information sending request comprises target data needing to be sent; according to the Web information sending request, Json format assembling is carried out; according to the Json data protocols, assembled request information is packaged; according to the Web information sending request, packaged data are sent to a background through Ajax data protocols and the Json data protocols; the background analyzes and processes the Json data according to the Web information sending request; according to results obtained by analyzing and processing the Json data, the background returns the processing results of the Json data. According to the method, the data can be processed and exchanged between a client and the background of the Web management system efficiently and rapidly, and the performance of the Web management system and customer experience can be improved.

Description

A data interaction method for web management system based on json data protocol

technical field

The invention relates to the field of computer application technology, in particular to a data interaction method for a Web management system based on the JSON data protocol.

Background technique

Json has become the implementation standard for internal data exchange in HTML5 applications, which is easy for humans to read and write, and is also easy for machines to parse and generate. Json can convert a set of data represented in a JavaScript object into a string, and then you can easily pass this string between functions, or pass a string from a web client to a server-side program in an asynchronous application. JavaScript interprets it easily, and Json can represent more complex structures than "name/value". For example, arrays and complex objects can be represented, not just simple lists of keys and values.

Ajax submission of data is more efficient than the original form submission. The original form submission hides the form. After updating the data, you need to go to a blank page and then submit and post-process the original page; ajax is not used, you can directly return to the original page Perform post-submission processing. It can be seen that Ajax can add one page less than hidden form submission.

Contents of the invention

The purpose of the present invention is to provide a data interaction method of a Web management system based on the json data protocol.

The object of the present invention is realized in the following manner, using Ajax asynchronous transmission technology, data adopts Json format transmission, processes Ajax request with unified interface, and content comprises: receive Web information sending request, and Web information sending request includes the target data that needs to send; Send requests according to web information to assemble in Json format; encapsulate the assembled request information according to Json data protocol; send requests according to web information to send encapsulated data to the background through Ajax and Json data protocols; the background sends requests to parse and process Json according to web information Data; the background returns the processing result of Json data according to the results of parsing and processing Json data; the specific exchange steps are as follows:

(1) User input request data on the client side of the web management system;

(2) Assemble the array data conforming to the Json format in the form of "name / value", for example {"name":"lilei","time":"10:29","age":"30"};

(3) Json encapsulation, according to the processing function agreed with the background, select the keyword key value and assemble it into the array, and then convert it into Json format. At this time, Json is the visible data on the client side, which is easier in the data submission process Check errors for easy development and debugging;

(4) Asynchronously transmit the Json data to the server-side processing engine to process the Json data, judge the response operation required by analyzing its keyword key value, call the processing process, and finally return;

(5) The processing result is in Json format, which identifies a stateful keyword. The client judges the response result according to the state. At the same time, if there is data that needs to be updated in the foreground, it will also be returned in Json, and the data is received through the Ajax callback function and displayed on the client. show.

The beneficial effect of the purpose of the present invention is: the present invention is based on the Web management system data interaction method of Ajax, Json data protocol can make efficient, fast processing and exchange data between the client of Web management system and the background, improve the performance of Web management system and customer experience.

Description of drawings

Figure 1 is a schematic structural diagram of a data interaction method for a Web management system based on Ajax and Json data protocols.

Detailed ways

The present invention will be described in detail below with reference to the accompanying drawings.

A data interaction method for a Web management system based on the json data protocol of the present invention, the content includes: receiving a Web information sending request, the Web information sending request includes the target data to be sent; performing Json format assembly according to the Web information sending request; according to the Json data The protocol encapsulates the assembled request information; sends the request according to the web information and sends the encapsulated data to the background through Ajax and Json data protocol; the background parses and processes the Json data according to the web information sending request; the background returns Json according to the result of parsing and processing the Json data the results of data processing;

Example:

The specific implementation steps are as follows:

(1) User input request data on the client side of the web management system;

(2) Assemble the array data conforming to the Json format in the form of "name / value", for example {"name":"lilei","time":"10:29","age":"30"};

(3) Json encapsulation, according to the processing function agreed with the background, select the keyword key value to assemble into the array, and then convert it into Json format. At this time, Json is a visual data on the client side, which is easier to check for errors during data submission, and is convenient for development and debugging;

(4) Asynchronously transmit the Json data to the server-side processing engine to process the Json data, judge the response operation required by analyzing its keyword key value, call the processing process, and finally return;

(5) The processing result is in Json format, which identifies a stateful keyword, and the client can judge the response result according to the state. At the same time, if there is data that needs to be updated at the front desk, it will also be returned in Json, and the data will be received through the Ajax callback function and displayed on the client.

Except for the technical features described in the instructions, all are known technologies by those skilled in the art.
