解決同源策略問題（伺服器端）

目錄

問題描述:

伺服器端解決方案

- apache2

- nginx

front.local.com 為前端**（a站）， img.local.com 為站（b站），當a站中的js訪問到b站資源時，報錯誤："the image has been blocked by cors policy"，即瀏覽器的同源策略限制了訪問。

首先， 確定apahe2.conf 有mod_headers支援

loadmodule headers_module /usr/lib/apache2/modules/mod_headers.so

serveradmin admin@php5 

servername img.local.com
serveralias *.img.local.com
documentroot ""
header set access-control-allow-origin *
header set access-control-allow-methods "post, get, options, delete, put"
header set access-control-allow-credentials true
header set access-control-allow-headers "origin, x-requested-with, content-type, accept, authorization"
# use mod_rewrite for pretty url support
rewriteengine on
# if a directory or a file exists, use the request directly
rewritecond % !-f
rewritecond % !-d
# otherwise forward the request to index.php
rewriterule . index.php
options indexes followsymlinks multiviews 
allowoverride all 
order allow,deny 
allow from all 

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"
