【问题描述】：
简介：我正在尝试使用 google Places API 和 URL Shorter API 创建一个网络应用程序。如果用户搜索某个地点，它会提取地点 ID 并创建一个长 URL -“http://search.google.com/local/writereview?placeid=”+place_id”，然后使用此长 URL 使用 Google URL 缩短 API 将其缩短，然后将其填充到文本字段中，以便用户可以复制生成的短 URL。我无法弄清楚为什么它不会缩短 URL。请注意我的实际代码中有 (api_key)。非常感谢任何帮助。
谢谢。

【问题讨论】：
-
只是一个问题...您是否必须通过 PHP 查询 URL 缩短器？
-
This 可能值得一读，因为 URL 缩短器将被 FDL 取代。
