ios - AFNetworking 获取完整的 http 响应

Question

我正在使用最新的 AFNetworking 查询我的服务器。

我的服务器端 PHP 正在发送一个 PHP 相关的错误，但我看不到错误是什么(所以我可以调试它)，因为 AFNetworking 需要一个 JSON。

谁能告诉我如何才能看到完整的 HTTP 结果。我研究过，我知道与 success/fail block 中的 operation.responseString 有关，我当前的 block 没有 AFHTTPRequestOperation* 操作，我无法以某种方式将它添加为另一个 block 变量。

非常感谢您的帮助。

下面的代码使用了

NSURL *url = [[NSURL alloc]initWithString:URL];
    AFHTTPClient *httpClient = [[AFHTTPClient alloc]initWithBaseURL:url];


    NSURLRequest *request = [httpClient multipartFormRequestWithMethod:@"POST" path:URLPATH parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData> formData)
                             {
                                 //...
                                 }

AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request
                                                                                        success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON){
                                                                                            NSLog(@"Inside the success block %@",JSON);
                                                                                            [[self delegate ]shareExerciseDone:JSON];
                                                                                            [[self delegate] activityIndicatorFinish];

                                                                                        }
                                                                                        failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON){

                                                                                            NSLog(@"Response text is: %@", operation.responseString);
                                                                                            NSLog(@"json text is: %@", JSON);
                                                                                            NSLog(@"Request failed with error: %@, %@", error, error.userInfo);

                                                                                            [[self delegate] activityIndicatorFinish];
                                                                                        }];

    [operation start];

错误

Request failed with 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=0xc1b4520 {NSDebugDescription=JSON text did not start with array or object and option to allow fragments not set.}, {
    NSDebugDescription = "JSON text did not start with array or object and option to allow fragments not set.";

不要使用AFJSONRequestOperation，只需使用AFHTTPRequestOperation。
