变量和文件URL未发布到服务器

Question

我正在尝试使用AFNetworking创建一个Http请求，它使用AFNetworking将一些变量和文件发送到服务器。但它也没有发送文件和变量。

请求被命中到服务器但它不带任何参数或文件，我仔细检查它的文件URL和参数dic不是空的

NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration backgroundSessionConfigurationWithIdentifier:[NSString stringWithFormat:@"com.app316.MWPl.backgroundconfiguration"] ];
configuration.sharedContainerIdentifier=kGroupNameToShareData;

AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration];

AFHTTPRequestSerializer *serializer = [AFHTTPRequestSerializer serializer];

    //parameters is NSDictionary With values in it
   NSMutableURLRequest *requesting=[serializer requestWithMethod:@"POST" URLString:urlString parameters:parameters error:&error99];

 NSURLSessionUploadTask *uploadTask4 =[manager uploadTaskWithRequest:requesting  fromFile:storeURL progress:nil completionHandler:^(NSURLResponse *response, id responseObject, NSError *error)
    {
        if (error)
        {
            NSLog(@"Error: %@", error);
            NSLog(@"Responce== %@", response);
            NSLog(@"Success: =%@", responseObject);
        }
        else
        {
            NSLog(@"Success: %@ %@", response, responseObject);
        }
    }];
    [uploadTask4 resume];
