Question

我在GAE上运行了wordpress多站点安装，一切都很好用。

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

这适用于非app-engine设置（apache / php）但是当我使用GCS上传器时，我似乎被重定向到主站点域的这个url：{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（通过拖放使用dropzone），我看到以下请求：

Accept:application/json
Accept-Encoding:gzip, deflate

哪个上传失败，我在控制台中看到了这个： XMLHttpRequest无法加载http：// {maindomain} /wp-signup.php?new=。请求的资源上不存在“Access-Control-Allow-Origin”标头。因此，不允许来源'http：// {customdomain}'访问。响应的HTTP状态代码为404.

我对可能出现的问题感到茫然。通过WP后端定期上传工作正常，所以它必须是我做错了。任何帮助表示赞赏。

Answer 1

我找到了问题的解决方案，因为我怀疑这是我做错了。

为简洁起见，我省略了一些if语句，这些语句导致$ url为空，然后传递给＆＃39; CreateUploadUrl＆＃39;这就是上传后它被重定向到默认网站的原因。

当你在漫长的一天之后深夜编码时会发生这种情况。

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