【问题描述】：

您好，我尝试使用 AFNetworking 从我的服务器在数据库中注册用户，但它不起作用。 ios代码如下：

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    [manager POST:@"http://www.myWebSite.com/user/newUser" parameters:dictonaryUser success:^(AFHTTPRequestOperation *operation, id responseObject) 
        NSLog(@"JSON: %@", responseObject);
     failure:^(AFHTTPRequestOperation *operation, NSError *error) 
        NSLog(@"Error: %@", error);
    ];

这是 php 代码：

header('Content-type: text/json');
    echo json_encode($_POST);

这里是错误：

2014-02-01 11:07:24.051 myApp[2534:70b] Error: Error Domain=NSCocoaErrorDomain Code=3840 "The operation couldn’t be completed. (Cocoa error 3840.)" (JSON text did not start with array or object and option to allow fragments not set.) UserInfo=0x8b9af60 NSDebugDescription=JSON text did not start with array or object and option to allow fragments not set.

感谢您的帮助

你能显示你的 JSON 响应吗？

【参考方案1】：

尝试添加此代码

AFJSONRequestSerializer *requestSerializer = [AFJSONRequestSerializer serializer];

[requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Accept"];

manager.requestSerializer = requestSerializer;

如果仍然无法正常工作，请参考此link
