Ngnix 配置容許多個域名跨域訪問

當瀏覽器發起ajax請求到其餘域名或者訪問其餘域名m3u8資源時,會出現跨域的問題,致使沒法正確訪問資源提示:css

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,可是此參數只容許配置單個域名「add_header Access-Control-Allow-Origin baidu.com」或者「add_header Access-Control-Allow-Origin *;」容許所有域名,當咱們須要容許多個域名跨域訪問時卻很差配置,能夠用map來實現,具體代碼以下:html

 第一種方式:nginx

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:segmentfault

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";

    }

}
