nginx sub-filter选项不生效的问题
注意需要使用--with-http_sub_module选项开启sub-filter支持
问题在于如果响应是gzip的形式的时候,sub-filter无法完成替换,一般可以通过添加proxy_set_header Accept-Encoding '';解决

        location /jenkins/  {
            proxy_pass http://jenkins.xxx/;
            proxy_redirect off;
            proxy_hide_header 'x-frame-options';
            proxy_set_header Accept-Encoding '';
            sub_filter 'src="/' 'src="';
            sub_filter 'href="/' 'href="';
            sub_filter_once off;
            add_header Access-Control-Allow-Origin *;
            add_header Access-Control-Allow-Methods 'GET,POST,OPTIONS,PUT,DELETE,PATCH';
            add_header Access-Control-Allow-Headers 'Authorization,Access-Control-Allow-Headers, Origin,Accept, X-Requested-With, Content-Type, Access-Control-Request-Method, Access-Control-Request-Headers';
        }
