使用方法：將 const f_uid = 108103; 中的 108103 改為你自己的用戶id，將腳本復制到browser的console里運行。

注意:

• 在Google Chrome macOS中console出于安全考慮自覺拒絕運行腳本。原因是：

  [Deprecation] Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user’s experience. For more help, check https://xhr.spec.whatwg.org/.
