Apache与Nginx网站跨域设置

前言

网站一般在需要共享资源给其他网站时（跨域传递数据），才会设置access-control-allow-origin HTTP头
设置Access-Control-Allow-Origin，可以解决多域名跨域问题
Access-Control-Allow-Origin * 等所有网站都可以跨域访问
Access-Control-Allow-Origin gqink.cn 允许gqink.cn跨域访问

Apache

<IfModule mod_headers.c>

   Header set Access-Control-Allow-Origin: "*"

   Header set Access-Control-Allow-Methods: "GET,POST,PUT,DELETE,OPTIONS"

   Header set Access-Control-Allow-Headers: "Content-Type"

</IfModule>

Nginx

add_header 'Access-Control-Allow-Origin' '*';
add_header 'Access-Control-Allow-Methods' 'PUT,POST,GET,DELETE,OPTIONS';
add_header 'Access-Control-Allow-Headers' 'Content-Type,Content-Length, Authorization, Accept,X-Requested-With';

或者

 location / {  
  add_header Access-Control-Allow-Origin *;
  add_header Access-Control-Allow-Headers "Origin, X-Requested-With, Content-Type, Accept";
  add_header Access-Control-Allow-Methods "GET, POST, OPTIONS";
} 

Html

<meta http-equiv="Access-Control-Allow-Origin" content="*" />

Java

response.setHeader("Access-Control-Allow-Origin", "*"); 

.net

Response.AddHeader("Access-Control-Allow-Origin", "*");
