我必须向需要 JSOn 的服务器发出发布请求。我正在使用以下代码发出请求：

    AFHTTPClient* httpClient = [[AFHTTPClient alloc] initWithBaseURL:[NSURL     URLWithString:SERVER_URL]];

     [httpClient setParameterEncoding:AFJSONParameterEncoding];
NSMutableURLRequest *jsonRequest = [httpClient requestWithMethod:@"POST" path:@"/"                    parameters:@{@"name":@"piggy"}];


    AFJSONRequestOperation *operation2 = [AFJSONRequestOperation JSONRequestOperationWithRequest:jsonRequest     success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {


     NSLog(@"RECEIVED: %@  ", JSON);

} failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {
    NSLog(@"Request Failed with Error: %@, %@", error, error.userInfo);
    //NSLog(@"GGG:%@",JSON);
}];

但我收到错误：

 Request Failed with Error: Error Domain=com.alamofire.networking.error Code=-1016 "Expected content type {(

错误消息对此进行了解释：您期望的是 JSON 响应，但实际响应是 HTML。它要么 1）您的 URL 错误，要么 2）您没有正确处理请求。
