关于跨域

禁止跨域实际上是服务端设置的一个消息头
只能在服务端删除或者利用代理服务器删除

在php页面中允许跨域

<?php
// 特殊字段,允许跨域
header('Access-Control-Allow-Origin:*');
header('Access-Control-Allow-Headers:Content-Type');
header('Access-Control-Allow-Methods:GET,POST,PUT,DELETE,OPTIONS');


echo "\r\n##########get by ip.kms.app #############################\r\n";
echo file_get_contents('php://input');
echo "\r\n##########get by ip.kms.app #############################\r\n";

?>

上面这个页面接受任何来源的数据
会将接收到的数据echo出来

代理服务器修改

如果源站设置了禁止代理,此时代理功能会遇到这个问题(由客户端:浏览器检查)
可以利用apache的header模块进行修改

Header unset content-security-policy

上面这个配置主要是删除所有安全限制,包括跨域请求
直接加到VirtualHost配置中就行

About cross-domains

The prohibition of cross-domain is actually a message header set by the server
can only be removed on the server side or with a proxy server

Allow cross-domains in php pages

<?php
// special field to allow cross-domain
header('Access-Control-Allow-Origin:*');
header('Access-Control-Allow-Headers:Content-Type');
header('Access-Control-Allow-Methods:GET,POST,PUT,DELETE,OPTIONS');


echo "\r\n##########get by ip.kms.app #############################\r\n";
echo file_get_contents('php://input');
echo "\r\n##########get by ip.kms.app #############################\r\n";

? >

This page above accepts data from any source
will echo out the received data

Proxy server modification

If the source site is set to disable proxying, the proxy function will encounter this problem (checked by the client:browser)
can be modified using apache's header module

Header unset content-security-policy

The above configuration mainly removes all security restrictions, including cross-domain requests
Just add it directly to the VirtualHost configuration
