Do a UTF-8 to the address to prevent the parameter inside the Chinese
NSString *urlstr = [string stringbyaddingpercentescapesusingencoding:nsutf8stringencoding];
Convert Address to URL format

Set Request mode

[Request sethttpmethod:@ "GET"];
Synchronous or asynchronous

Because the type of the data is not determined, the ID generic pointer is used to receive
