Several methods of parsing string into json are summarized. For more information, see. 1. The old method:
The Code is as follows:

First of all, a simple example (the simplest I do not speak, many online), to help beginners understand how to use Gson:For example, we want to parse one of the following JSON:String json = {"A": "+", "B": [{"B1": "B_value1", "B2": "B_value2"},{"B1": "B_value1", "B2": "B_value2"}], "C": {"C1": "C_ Value1 "," C2 ":" C_value2 "}}First we need to define a serialized bean, which, in the form of an inner class,
First of all, let's start with a simpler example (the simplest I don't speak, a lot on the web) to help beginners understand how gson is used:
For example, we're going to parse one of these JSON:
String json = {"A": "M",
"B": [{"B1": "B_value1", "B2": "B_value2"},
{"B1": "B_value1", "B2": "B_value2"}],

The JSON data obtained in the example above is a nested JSON:{"Comments": [{"Content": "Very good", "id": 1, "nickname": "Nani"},{"content": "Yo West yo West", "id": 2, "nickname": "Johnny"}]}To get the JSON data, there is a simple method $.getjson () in jquery that can be implemented.The following is a description of the official API for $.getjson ():Jquery.getj

Jquery map () filter and traverse Arrays

The previous blog said that the method for parsing JSON into Java is
These jar packages, however, encountered a problem at the parsing layer, that is, an exception will be thrown when the time string is converted to the Java timestamp object.

Because the get authorization returns a JSON string in the following format:1 {2 ' code ': A0000,3 4 {5 ' Access_token ': access_token,//access token 6 ' expires_in ': 60,//expiry time 7 ' refresh_token ': refresh_token,//Refresh token 8 }9 }The next step is to parse the string to get the appropriate information, such as the status code and the access token.There are se
