CloudStorageTools::createUploadUrl 上传时重定向到不正确的 url

Question

我有一个 wordpress multi-site 在 GAE 上安装运行，大部分情况下一切都很好。

我希望用户通过 front-end 将文件上传到位于 {customdomain.com}/app/client/{client_id}/upload_profile_image 的自定义文件处理程序/（我正在使用重写规则）

这适用于 non-app-engine 设置 (apache/php)，但是当我使用 GCS 上传器时，我似乎被重定向到位于 url 的主站点域：{maindomain }/wp-signup.php?new=

这是基于 wp google-app-engine 插件代码的代码：

    $url = site_url('/app/client/' . $Client->ID . '/upload_profile_image/');
    require_once 'google/appengine/api/cloud_storage/CloudStorageTools.php';
    $options = [
         'gs_bucket_name' => get_option('appengine_uploads_bucket', ''),
         'url_expiry_time_seconds' => 60 * 60 * 24, // One day is the maximum
    ];
    $wp_maxupsize = wp_max_upload_size();
    // set max_bytes_per_blob option only if max upload size is a positive int
    if (is_int($wp_maxupsize) && $wp_maxupsize > 0) {
       $options['max_bytes_per_blob'] = $wp_maxupsize;
    }
    // Setup internal authentication
    $sign_result = \google\appengine\api\app_identity\AppIdentityService::signForApp(AUTH_KEY . get_current_user_id());
    $url = add_query_arg('gae_auth_user', get_current_user_id(), $url);
    $url = add_query_arg('gae_auth_key', $sign_result['key_name'], $url);
    $url = add_query_arg('gae_auth_signature', urlencode(base64_encode($sign_result['signature'])), $url);

     $url = \google\appengine\api\cloud_storage\CloudStorageTools::createUploadUrl($url,$options);

当我提交文件时（通过 drag/drop 使用 dropzone）我看到以下请求：

Accept:application/json

我不知道可能是什么问题。通过 WP 后端定期上传工作正常，所以这一定是我做错了什么。感谢任何帮助。

Answer 1

我找到了问题的解决方案，因为我怀疑是我做错了什么。

为简洁起见，我省略了一些导致 $url 在传递给 'CreateUploadUrl' 之前为空的 if 语句，这就是上传后它被重定向到默认站点的原因。

这就是当您在漫长的一天之后编码到深夜时发生的情况。
