Google Closure编译REST Api突然引发错误405“方法不允许”

Question

我已经使用Closure作为y应用程序的一部分来压缩Javascript了一段时间，但是刚开始出现错误 405 - Method not allowed

我下面的代码已经工作了几年，但是现在已经停止了。

注意：仅当我的应用程序中的Javascript文件中检测到任何更改时，才经常调用此方法。

除了此，我从Closure应用程序中没有得到更多的错误信息。

显然，此代码执行POST操作。如果我使用在https://closure-compiler.appspot.com/home上找到的表单，它可以工作，但是如果我浏览到URL或使用我的代码得到Error 405，则几乎就像我的代码正在尝试一种GET方法。 ..但不是...

有任何想法吗？

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