file_get_contents（）返回“无法打开流”何时点击HTTPS [英] file_get_contents() returns "failed to open stream" when hitting HTTPS

问题描述

file_get_contents（）返回无法打开流。

file_get_contents() is returning "failed to open stream" when I call it on an HTTPS URL.

Warning: file_get_contents(https://google.com) [function.file-get-contents]: failed to open stream: No error in E:\\htdocs\callback3.php on line 5

同一个电话将使用非SSL网址。

Same call will work with a non-SSL URL.

起初，我认为这是我的webhoster的一个安全问题，但我已经通过phpinfo（）验证了允许url打开确实是允许的。我也试过这个代码，并验证了它的工作原理：

At first, I thought it was a security issue with my webhoster, but I have verified with phpinfo() that allow url open is indeed allowed. I have also tried this code and verified it works:

任何人都有理由的file_get_contents（）与HTTPS URL没有任何想法

Anyone have any ideas why file_get_contents() is failing with an HTTPS URL?

更新：人们正确地指出这是一个HTTPS问题。我的webhoster声称这应该有效，并且不知道如何解决这个问题。任何人都有特定的指示我可以为他们的IIS7安装提供它们吗？

update: People correctly pointed out this was an HTTPS issue. My webhoster claims this should work, and has no idea how to resolve this. Anyone have specific directions I can give them for their IIS7 setup?

推荐答案

这可能是因为他们正在使用安全协议 HTTPS 。这很奇怪，但在他们的例子中，facebook给出了类似的例子。

That is probably because they are using the secure protocol https. This is strange though, in their examples, facebook is giving the similar example.
