跨域访问解决方案 使用Ajax跨域请求资源，Nginx作为代理，出现以下错误： The 'Access-Control-Allow-Origin' header contains multiple values...'*, *', but only one is allowed 解决方法： 使用Nginx作为反向代理服务器，并在配置中对应的location下添加上如下的设置 add_header 'Access-Control-Allow-Origin...'Access-Control-Allow-Origin' '*'; add_header 'Access-Control-Allow-Credentials' 'true'; add_header...Access-Control-Allow-Origin *; add_header Access-Control-Allow-Methods GET,POST,PUT,DELETE,PATCH,...Access-Control-Allow-Origin *; add_header Access-Control-Allow-Methods GET,POST,PUT,DELETE,PATCH,

Nginx设置多域名 尝试直接通过 Nginx 的add_header模块追加 Access-Control-Allow-Origin 值实现，如下： add_header Access-Control-Allow-Origin...http://www.fq.yii.com; add_header Access-Control-Allow-Origin http://www.d.yii.com; 接口 请求 和 响应头 如下：...Response Headers Access-Control-Allow-Origin: http://www.fq.yii.com Access-Control-Allow-Origin: http...The ‘Access-Control-Allow-Origin’ header contains multiple values ‘http://www.fq.yii.com, http://www.d.yii.com...由此可知，Yii2 在控制器行为中设置 Origin 项，只是一个域名白名单，而返回的 Access-Control-Allow-Origin 同请求的域名一致且在这个白名单中，这个 Access-Control-Allow-Origin
