objective-c - json data processing

Question

OC How to pass {"message":{"function":"user_login","user":{"name":"admin","password":"admin"}}} to pass this login request json through socket TCP to server

Answer 1

I know the answer. I tried it myself and just wrote it
`NSDictionary *dict = @{

                    @"message":@{
                    @"function":@"user_login",
                    @"user":@{
                    @"name":_TextField.text,
                    @"password":_PassTextField.text
                                         }}};`
                                         
                                 将字典转成NSData在转成NSSString后面拼接上数据包的结尾，之后在转换成NSData通过tcp 发出去就可以了

Send data via ajax request

Answer 3

var url = "http://www.xxx.com"
var data = {"message":
    {"function":"user_login",
         "user":{   
                 "name":"admin",
                 "password":"admin"
                 }
    }
}

$.ajax({
            cache: true,
            type: "POST",
            url: url,
            data: data
            async: false,
            error: function(request) {
                alert("NO");
            },
            success: function(data) {
                alert("OK")
            }
        });

Answer 4

It is not recommended to manually operate the socket to complete things like sending login requests. Why not try a mature network framework such as AFNetworking?
