【问题描述】：

我用这个方法：

NSDictionary *params = @@"email" : email,
                         @"password" : pass
                         ;
NSString* HOST_URL = @"http://server.com:8080";

AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:[NSURL URLWithString:HOST_URL]];
NSMutableURLRequest *request = [httpClient requestWithMethod:@"POST"
                                                        path:@"/login"
                                                  parameters:params];

AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
[httpClient registerHTTPOperationClass:[AFHTTPRequestOperation class]];

[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) 

    NSLog(@"Response: %@", [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding]);
    NSDictionary *response = (NSDictionary*)[NSJSONSerialization JSONObjectWithData:operation.responseData options:kNilOptions error:nil];

    //HERE YOU HAVE A RESPONSE (your server answer)
 failure:^(AFHTTPRequestOperation *operation, NSError *error) 
    NSLog(@"Error: %@", error.localizedDescription);
];

[operation start];

我有回应：

"Result":"fail","Message":"unexpected end of JSON input","Data":null

我的要求是通过 POST 在变量“数据”中发送登录名和密码，但是如果我在这里通过字典中的文本发送请求，如何在我的服务器上发送此变量？

【问题讨论】：

您要上传到哪个服务器？如果您需要像普通 Web 表单那样发送 POST，请查看***.com/questions/3508338/…

如果您已经确定要使用 AFNetworking 2.0，如your other question would suggest，那么我建议您在下面接受 user3200708 的回答（这样他就会因帮助您和您而获得“声誉”）将关闭这个问题）。你真的不应该同时打开这么多（我数了四五个）重复的问题。

我需要在可变数据中发送数据，对此很抱歉

感谢您清理旧问题！我将在your other question 解决您的“变量数据”问题。在 cmets 中讨论多个问题是没有意义的！

【参考方案1】：

NSDictionary *params = @@"email" : email,
                     @"password" : pass
                     ;
NSString* HOST_URL = @"http://server.com:8080";

AFHTTPRequestOperationManager *operationManager = [AFHTTPRequestOperationManager manager];
[operationManager POST:HOST_URL parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject)

// Enter what happens here if successsful.

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

// Enter what happens here if failure happens

【参考方案2】：

我知道了：

NSString *URLString = @"http://server.com:8080/login";
//    login = @"user1@1q2w3e"; // user1@1q2w3e user3@frcity
//    password = @"1q2w3e";

NSString* data = @"\"email\": \"user1@1q2w3e\" ,\"password\": \"1q2w3e\"";

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.requestSerializer = [AFHTTPRequestSerializer serializer];
NSDictionary *params = @@"data" : data;
[manager POST:URLString parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) 
    NSLog(@"JSON: %@", responseObject);
 failure:^(AFHTTPRequestOperation *operation, NSError *error) 
    NSLog(@"Error: %@", error);
];
