在 php 中 whateverorigin.org 调用替换为本地代理


Replace whateverorigin.org call with local proxy in php

我目前正在一些javascript中使用 whateverorigin.org 来检索URL作为JSON对象,因为第三方站点没有通过其JSON API提供其功能之一。

我想从我的网站中删除此依赖项,因为 whateverorigin.org 破坏了 HTTPS/SSL 浏览器对安全内容的检查,因为它是一个明确的 http 调用。

有人这样做过吗?我在任何地方都没有找到它的例子。

提前感谢您的回复!

好的,所以自从我第一次输入这个问题以来,我已经找到了一些示例,并在php中拼凑了一个有效的代理函数......随意将其用于您自己的目的!

希望这对某人有所帮助!
