AFNetworking上傳圖片錯誤

Question

我試圖將圖片上傳到服務器，但我遇到了問題。下面是我的代碼：

UIImage *image = [UIImage imageNamed:@"profileImage.png"]; 

NSData *imageData = UIImagePNGRepresentation(image); 

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; 
[manager POST:@"http://myserver.com/upload_img.php?&user_id=6&image=image.png" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData){ 
    [formData appendPartWithFileData:imageData name:@"image" fileName:@"image.png" mimeType:@"image/png"]; 
} 

    success:^(AFHTTPRequestOperation *operation, id responseObject){ 
    NSLog(@"Success: %@", responseObject); 
} 

     failure:^(AFHTTPRequestOperation *operation, NSError *error){ 
    NSLog(@"Error: %@", error); 
}]; 

我收到「成功：{錯誤=‘’;}」從的NSLog，但服務器沒有更新。我究竟做錯了什麼？

編輯

好，圖像被正確上傳，但是我們不得不使用GET而不是POST的服務器上檢索圖像。爲什麼會這樣？

試試這個

UIImage *image = [UIImage imageNamed:@"profileImage.png"]; 
     NSData *imageData = UIImageJPEGRepresentation(image, 0.5); 
     AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; 
    [manager POST:@"http://myserver.com/upload_img.php?&user_id=6&image=image.png" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData){ 

    } 
    { 
      [formData appendPartWithFileData:imageData name:@"image" fileName:@"image.png" mimeType:@"image/png"]; 
     } success:^(AFHTTPRequestOperation *operation, id responseObject) { 
      NSLog(@"Success: %@", responseObject); 
     } failure:^(AFHTTPRequestOperation *operation, NSError *error) { 
      NSLog(@"Error: %@", error); 
     }];

固定！通過POST調用，我需要設置正確的參數：@{user_id:@6}。現在工作很好！
