。我如何使用它?
I want to make HTTPS calls from an HTTP webpage. I hope to solve this problem with Access-Control-Allow-Origin
. How can I use it?
推荐答案
在HTTPS页面(你是从HTTP页面请求)设置页眉:
On the HTTPS page (that you are requesting from the HTTP page) set the header:
访问控制 - 允许 - 产地: http://www.example.com
Access-Control-Allow-Origin: http://www.example.com
您可以在PHP中做到这一点有:
You can do this in PHP with:
<?php
header("Access-Control-Allow-Origin: http://www.requesting-page.com");
?>
另外,如果不工作,您可以在HTTP服务器(该请求是来自)上创建一个文件,该文件下载和显示的内容,这可以在PHP中加上:
Alternatively if that doesn't work, you could create a file on your HTTP server (where the request is coming from) that downloads and displays the contents, this can be done in PHP with:
<?php
echo file_get_contents("https://www.requested-page.com");
?>
我不会建议这样做,因为它需要更多的带宽,是不是好的做法,它应该只被使用,如果你不能做的第一选择。此外,如果开发商已经设置了访问控制,以限制它可能是有原因的。
I would not advise doing this as it requires extra bandwidth and isn't good practice, it should only be used if you can't do the first option. Furthermore, if a developer has set the access control to be restricted it's probably for a reason.
