通过nginx做为反向代理，将yapi反向代理到二级目录上。
需要通过再次代理来实现。
nginx配置文件如下：
server {
listen 80;
server_name yourdomain.com;
location /yapi_forward/ {
proxy_pass http://127.0.0.1:3000/;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
proxy_http_version 1.1;
proxy_set_header Accept-Encoding 'gzip';
gunzip on;
}
location /yapi/ {
proxy_pass http://yourdomain.com/yapi_forward/;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
proxy_http_version 1.1;
proxy_set_header Accept-Encoding "";
sub_filter '"/prd' '"/yapi/prd';
sub_filter '"/iconfont' '"/yapi/iconfont';
sub_filter '"/image' '"/yapi/image';
sub_filter '"/api' '"/yapi/api';
sub_filter '"/user' '"/yapi/user';
sub_filter '"/group' '"/yapi/group';
sub_filter '"/project' '"/yapi/project';
sub_filter '"/mock' '"/yapi/mock';
sub_filter 'path:"/' 'path:"/yapi/';
sub_filter 'to:"/' 'to:"/yapi/';
sub_filter 'history.push("/' 'history.push("/yapi/';
sub_filter_types *;
sub_filter_once off;
}
}
