1. Choice of Scheme:

1.1. httpclient Library to get raw JSON data

1.2. JSON library Gets the HTML content we need

1.3. use Jsoup to parse the HTML content we obtained

2.1, it will automatically complement the entire HTML header and tail (

Processing method: manually specify Parser.xmlparser ()

2.2, If the attribute is not wrapped in 2 double quotation marks, It will be the 2 double quotation marks complete ... This function cannot be closed in jsoup ...
