IOS 使用AFNetworking 接收JSON数据(Get and Post)

首先将AFNetworking的库加进来（GitHub搜索），然后如下代码

(GET)

IOS端

AFHTTPRequestOperationManager *mgr = [AFHTTPRequestOperationManagermanager];

mgr.responseSerializer.acceptableContentTypes = [mgr.responseSerializer.acceptableContentTypessetByAddingObject:@"text/html"];//Very Important

[mgr GET:@"test.php"parameters:nilsuccess:^(AFHTTPRequestOperation *operation,id responseObject) {

       NSDictionary *d = responseObject;

        NSString *str = [NSStringstringWithFormat:@"age:%@;\ngender:%@;\nname:%@\n\nresult:%@",d[@"content"][@"age"],d[@"content"][@"gender"],d[@"content"][@"name"],d[@"result"]];

        

    } failure:^(AFHTTPRequestOperation *operation,NSError *error) 

    {

    

    }];

服务器php脚本

<?php

$content = array(

"userid"=>$_GET['userid'],

"name"=>"rose",

"age"=>"2099",

"gender"=>"female",

"subs"=>array("maths","geo","phy")

);

$result="pass";

$ret = array(

    "result"=>$result,

    "content"=>$content,

    "mask"=>"mask"

);

echo json_encode($ret);

POST

AFHTTPRequestOperationManager *mgr = [AFHTTPRequestOperationManagermanager];

mgr.responseSerializer.acceptableContentTypes = [mgr.responseSerializer.acceptableContentTypessetByAddingObject:@"text/html"];//Very Important

NSDictionary *param = @{@"name:@"jack",@"age":@"33"};

[mgr POST:@"test.php"parameters:param success:^(AFHTTPRequestOperation *operation,id responseObject) {

       NSDictionary *d = responseObject;

        NSString *str = [NSStringstringWithFormat:@"age:%@;\ngender:%@;\nname:%@\n\nresult:%@",d[@"content"][@"age"],d[@"content"][@"gender"],d[@"content"][@"name"],d[@"result"]];

    } failure:^(AFHTTPRequestOperation *operation,NSError *error) 

    {

      operation.response.statusCode;//404 401之类

    }];

server端略

PS：有的时候需要输入用户名和密码：http://admin:[email protected]/test.php

如果发送的时候需要json格式，则需要设置mgr.requestSerializer = [AFJsonRequestSerializer serializer];
