Symfony -上传文件会将我发送到_wtd url

use Symfony\Component\HttpFoundation\Request;

// 处理上传文件的控制器方法
public function uploadFile(Request $request)
{
    $file = $request->files->get('file'); // 获取上传的文件

    // 将文件保存到指定位置
    $file->move('/path/to/directory', $file->getClientOriginalName());

    // 将文件发送到_wtd URL
    $wtdUrl = 'https://example.com/_wtd';
    $httpClient = new \GuzzleHttp\Client();
    $response = $httpClient->post($wtdUrl, [
        'multipart' => [
            [
                'name' => 'file',
                'contents' => fopen('/path/to/directory/'.$file->getClientOriginalName(), 'r')
            ]
        ]
    ]);

    // 处理_wtd URL的响应
    // ...

    return $this->redirectToRoute('success_page');
}
