当浏览器发起ajax请求到其他域名或者访问其他域名m3u8资源时,会出现跨域的问题,导致无法正确访问资源提示:
No'Access-Control-Allow-Origin' header is present on the requested resourse.Origin 'http//localhost:8088' is therefore not allowed access.
在nginx上的解决方案是配置Access-Control-Allow-Origin来解决,但是此参数只允许配置单个域名“add_header Access-Control-Allow-Origin baidu.com”或者“add_header Access-Control-Allow-Origin *;”允许全部域名,当我们需要允许多个域名跨域访问时却不好配置,可以用map来实现,具体代码如下:
第一种方式:
map $http_origin $corsHost { default 0; "~http://www.haibakeji.com" http://www.haibakeji.com; "~http://m.haibakeji.com" http://m.haibakeji.com; "~http://wap.haibakeji.com" http://wap.haibakeji.com; } server { listen 80; server_name www.haibakeji.com; root /nginx; location / { add_header Access-Control-Allow-Origin $corsHost; } }

第二种方式:
location ~* .(ttf|ttc|otf|eot|woff|font.css)$ { if ($http_origin = 'http://backend.test.com') { add_header 'Access-Control-Allow-Origin' "$http_origin"; } if ($http_origin = 'http://wap.test.com') { add_header 'Access-Control-Allow-Origin' "$http_origin"; } } 原文地址:https://www.jianshu.com/p/f2ec1d6af047
