Ios 正在使用AFNetworking将图像上载到Parse.com，导致图像损坏

我正在尝试使用AFNetworking 2.0将图像上载到Parse.com。 当我下载存储在“Parse”上的图像时，生成的文件已损坏

通过进行差异分析，我发现以下数据已附加到开头：

文件末尾还附加了“边界”数据

我做错了什么？Mime类型

我使用“curl”发送相同的文件，一切都正常

这是我用于发送的代码：

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager setResponseSerializer:[AFJSONResponseSerializer serializer]];

[manager.requestSerializer setValue:@"image/jpeg" forHTTPHeaderField:@"Content-Type"];

[headers enumerateKeysAndObjectsUsingBlock:^(NSString *key, NSString *value, BOOL *stop) {
    [manager.requestSerializer setValue:value forHTTPHeaderField:key];
}];

[manager POST:@"https://api.parse.com/1/files/imagefile.jpg"
   parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData)
      {
          NSData *imgData = UIImageJPEGRepresentation(image, 1.0f);

          [formData appendPartWithFileData:imgData
                                      name:@"imagefile"
                                  fileName:@"imagefile.jpg"
                                  mimeType:@"image/jpeg"];
      }
      success:^(AFHTTPRequestOperation *operation, id responseObject) {
          success(operation, responseObject);
      }
      failure:^(AFHTTPRequestOperation *operation, NSError *error) {
          failure(operation, error);
      }
 ];

您不使用Parse.com SDK执行此操作有什么特殊原因吗？是的，不希望代码与Parse'SDK耦合，因为我们可能会更改后端。一切都使用RESTAPI。

NSMutableString *urlString = [NSMutableString string];
[urlString appendString:@"https://api.parse.com/1/"];
[urlString appendFormat:@"files/imagefile.jpg"];

NSURL *url = [NSURL URLWithString:urlString];

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:@"POST"];
[request addValue:@"***********" forHTTPHeaderField:@"X-Parse-Application-Id"];
[request addValue:@"***********" forHTTPHeaderField:@"X-Parse-REST-API-Key"];
[request addValue:@"image/jpeg" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:UIImageJPEGRepresentation(image, 0.3f)];

NSURLResponse *response = nil;
NSError *error = nil;

[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];

NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse*)response;
NSString *fileUrl = [httpResponse allHeaderFields][@"Location"];
