AFNetworking 3.0の失敗ブロックでresponseObjectを取得

aFNetworking 3.xの障害ブロックから応答文字列を取得するにはどうすればよいですか？

2.xバージョンでは、その方法は次のとおりでした。

[manager GET:path parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSDictionary *dictionary_FetchResult = responseObject;
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSDictionary *dictionary_FetchResult = operation.responseObject;
}];

ただし、3.xバージョンでは、以下に示すように、戻りブロックのパラメーターに操作はありません。

[manager POST:path parameters:parameters progress:^(NSProgress * _Nonnull uploadProgress) {
        } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
    NSDictionary *dictionary_FetchResult = responseObject;
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
    NSLog(@"Error: %@", error);
}];

だから誰かがそれを達成できたらいいなと思っていました。

あなたの失敗ブロックでこれをしてください：

 NSString* errResponse = [[NSString alloc] initWithData:(NSData *)error.userInfo[AFNetworkingOperationFailingURLResponseDataErrorKey] encoding:NSUTF8StringEncoding];
NSLog(@"%@",errResponse);

Swiftの場合：-

var errResponse: String = String(data: (error.userInfo[AFNetworkingOperationFailingURLResponseDataErrorKey] as! NSData), encoding: NSUTF8StringEncoding)
NSLog("%@", errResponse)

Swift 4.1に更新

var errResponse: String = String(data: (error._userInfo![AFNetworkingOperationFailingURLResponseDataErrorKey] as! Data), encoding: String.Encoding.utf8)!
print(errResponse)

完璧に機能するこのソリューションを見つけました。スイフトで

if let userInfo : NSDictionary = error.userInfo as NSDictionary {
     if let innerError : NSError = userInfo.objectForKey("NSUnderlyingError") as? NSError {

         if let innerUserInfo : NSDictionary = innerError.userInfo as NSDictionary {

              if innerUserInfo.objectForKey(AFNetworkingOperationFailingURLResponseDataErrorKey) != nil {
                   let StrError = NSString(data: innerUserInfo.objectForKey(AFNetworkingOperationFailingURLResponseDataErrorKey) as! NSData, encoding: NSUTF8StringEncoding)

                   print(StrError)
              }
         } else if let errResponse: String = String(data: (error.userInfo[AFNetworkingOperationFailingURLResponseDataErrorKey] as! NSData), encoding: NSUTF8StringEncoding) {
              print(errResponse)
         }
     }

}

そしてObjective-Cコードは

    NSDictionary *userinfo1 = [[NSDictionary alloc] initWithDictionary:error.userInfo];

if(userinfo1) {
      NSError *innerError = [userinfo1 valueForKey:@"NSUnderlyingError"];
      if(innerError) {
         NSDictionary *innerUserInfo = [[NSDictionary alloc] initWithDictionary:innerError.userInfo];
         if(innerUserInfo)
         {
              if([innerUserInfo objectForKey:AFNetworkingOperationFailingURLResponseDataErrorKey])
              {
                   NSString *strError = [[NSString alloc] initWithData:[innerUserInfo objectForKey:AFNetworkingOperationFailingURLResponseDataErrorKey] encoding:NSUTF8StringEncoding];
                            NSLog(@"Error is : %@",strError);
              }
         }
      } else
      {
           NSString *errResponse = [[NSString alloc] initWithData:[userinfo1 valueForKey:@"AFNetworkingOperationFailingURLResponseDataErrorKey"] encoding:NSUTF8StringEncoding];

          if(errResponse)
          {
               NSLog(@"%@",errResponse);
          }
      }
}

GitHub で解決策を見つけました：

@interface ResponseSerializer : AFJSONResponseSerializer
@end

@implementation ResponseSerializer

- (id)responseObjectForResponse:(NSURLResponse *)response
                       data:(NSData *)data
                      error:(NSError *__autoreleasing *)errorPointer
{
    id responseObject = [super responseObjectForResponse:response data:data error:errorPointer];
    if (*errorPointer) {
        NSError *error = *errorPointer;
        NSMutableDictionary *userInfo = [error.userInfo mutableCopy];
        userInfo[@"responseObject"] = responseObject;
        *errorPointer = [NSError errorWithDomain:error.domain code:error.code userInfo:[userInfo copy]];
    }
    return responseObject;
}

@end

そして、それをあなたのマネージャーに割り当てます：

self.manager.responseSerializer = [ResponseSerializer serializer];

ここでいくつかのコードを修正し、オプションを適切に処理しました。 Swift 3（.1）...

let nserror = error as NSError
if let errordata = nserror.userInfo[AFNetworkingOperationFailingURLResponseDataErrorKey] as? Data {
    if let errorResponse = String(data: errordata, encoding: String.Encoding.utf8) {
        print("errorResponse: \(errorResponse)")
    }
}
