无法读取数据,因为格式不正确."

Question

] 2我正在使用AFNetworking将数据发送到server.Below是我的代码:

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    [manager setRequestSerializer:[AFJSONRequestSerializer serializer]];
    [manager setResponseSerializer:[AFJSONResponseSerializer serializer]];
    [manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];


    NSMutableDictionary *dict = [[NSMutableDictionary alloc]init];

    [dict setValue:[[arrLoginDetails objectAtIndex:0] objectForKey:@"id"] forKey:@"user_id"];

    [dict setValue:[[arrLoginDetails objectAtIndex:0] objectForKey:@"id"] forKey:@"shipper_id"];

    [dict setValue:strUuid forKey:@"imageOrderId"];

    [dict setValue:@"1" forKey:@"type"];

    NSData * imageData = UIImageJPEGRepresentation([aryImages objectAtIndex:0], 0.7);


   if([imageData length]>0){
    NSString *base64String = [imageData base64EncodedStringWithOptions:0];


    if([base64String length]>0){
    [dict setValue:base64String forKey:@"file_path"];

       NSString * reqFormat= [NSString stringWithFormat:@"%@&email=%@&dev_id=%@",UploadImage,[[arrLoginDetails objectAtIndex:0] objectForKey:@"email"],APP_DELEGATE.stringDeviceID];

 [manager POST:reqFormat parameters:dict1 success:^(AFHTTPRequestOperation *operation, id responseObject)
     {
  }failure:^(AFHTTPRequestOperation *operation, NSError *error)
     {
         NSLog(@"error:%@",error.debugDescription);

 }

以下是我得到的错误:

无法读取数据,因为格式不正确.

错误:

错误:错误域= NSCocoaErrorDomain代码= 3840"没有值." UserInfo = {NSDebugDescription =无值.}

如果我nslog error.debugdescription我得到"数据无法读取,因为它的格式不正确".

请帮我解决这个错误.

谢谢.

Answer 1

试试以下代码:

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

AFJSONRequestSerializer *serializer = [AFJSONRequestSerializer serializer];
[serializer setStringEncoding:NSUTF8StringEncoding];

manager.requestSerializer=serializer;
manager.responseSerializer.acceptableContentTypes= [NSSet setWithObjects:@"text/html",@"application/json", nil];

 [manager POST:reqFormat parameters:dict1 progress:nil success:^(NSURLSessionTask *task, id responseObject)
     {
         //Print response
     } failure:^(NSURLSessionTask *operation, NSError *error) {
         //Print error
     }];

在AFNetworking 3.0中AFHTTPRequestOperationManager被取代AFHTTPSessionManager.
