Google Closure 编译REST Api 突然抛出错误405 "Method not allowed"

Question

我已经使用 Closure 作为 y 应用程序的一部分来压缩 Javascript 一段时间了，但刚开始出现错误 405 - Method not allowed

我下面的代码已经工作了几年，但现在已经停止了。

注意：这并不经常调用，只是在我的应用程序的 Javascript 文件中检测到任何更改时调用。

我从 Closure 应用程序中没有得到比这更多的错误信息。

显然这段代码执行了一个POST操作。如果我使用此处找到的表单 https://closure-compiler.appspot.com/home，它可以工作，但如果我浏览到 URL 或使用我的代码，我会得到 Error 405，这几乎就像我的代码正在尝试 GET 方法...但它不是...

有什么想法吗？

Closure REST api 正在重定向到 https，您可能想尝试直接 POST 到“https://closure-compiler.appspot.com/compile”以避免重定向。
