當瀏覽器發起ajax請求到其他域名或者訪問其他域名m3u8資源時,會出現跨域的問題,導致無法正確訪問資源提示:
No'Access-Control-Allow-Origin' header is present on the requested resourse.Origin 'http//localhost:8088' is therefore not allowed access.
在nginx上的解決方案是配置Access-Control-Allow-Origin來解決,但是此參數只允許配置單個域名“add_header Access-Control-Allow-Origin baidu.com”或者“add_header Access-Control-Allow-Origin *;”允許全部域名,當我們需要允許多個域名跨域訪問時卻不好配置,可以用map來實現,具體代碼如下:
第一種方式:
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; } }

第二種方式:
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
