Although there are many ideas about how XML has the cross-platform and cross-language advantages, unless it is applied to Web Services, in common Web applications, developers often use their brains for XML parsing. Whether the server generates or processes XML, or the client uses JavaScript to parse XML, it often leads to complicated code and extremely low development efficiency. In fact, for most Web applications, they do not need complicated XML to transmit data at all, and XML scalability is
JSON format data generation and parsing for IOS development, json format for ios development
This article describes how to generate and parse JSON data in IOS development from four aspects:
1. What is JSON? 2. Why should we use data in JSON format? 3. How to generate data
JSON is a JavaScript native format, which means that JSON data processing in JavaScript does not require any special APIs or toolkit. If you need it, you can understand JSON (JavaScript Object Notation) it is a lightweight data exchange format and uses a text format completely independent of languages. It is an ideal data exchange format.
This article describes how to use the Go language library to convert objects to JSON format, transfer them in the channel, and convert the information in JSON format back to the object.1, the Go Language JSON libraryThe go language comes with a JSON conversion library of Encoding/
Although there is a lot of publicity about how XML has cross-platform, Cross-language advantages, however, unless applied to web Services, developers often have a brain for XML parsing in ordinary Web applications, whether it's server-side generation or processing XML, or client JavaScript parsing XML, often leads to complex code, very low development efficiency. In fact, for most Web applications, they do not need complex XML to transmit data, XML extensibility has little advantage, and many AJ

Processing cache data verification with JSON is the most challenging and changing part of every enterprise Web application. Usually, metadata verification will mix the JavaScript module into the server code. In this article, you will learn how to cache metadata on the client with the help of the server code. The server code will provide string-based metadata in the form of JSON (JavaScript Object Notation.
