Nginx配置反向代理遇到403错误的问题解决

http {
     
    include       mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for" '
                      '"$http_referer" "$http_host"' ;

    access_log  logs/access.log  main;

    sendfile        on;
    tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    gzip  on;
    resolver 8.8.8.8;
    underscores_in_headers on; #下面的链接中有"_"，默认Nginx会忽略有"_"的地址

    server {
     
        listen       8082;
        server_name  localhost;

        autoindex off;

        #charset koi8-r;

        access_log  logs/host.access.log  main;

        location / {
     
            root   html;
            index  index.html index.htm;
                location ^~/gaode {
     
					proxy_set_header Host geo.datav.aliyun.com;
					proxy_set_header X-Real-IP $remote_addr;
					proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
					proxy_set_header X-Forwarded-Proto $scheme;
					#proxy_pass_header Server;
					proxy_redirect off;
					proxy_pass http://geo.datav.aliyun.com/areas_v2/bound/100000_full.json;
				}
		}
}

问题
1、http://geo.datav.aliyun.com/areas_v2/bound/100000_full.json中有"_"，被默认忽略了，需要在http中打开**underscores_in_headers on;**设置。
2、在Host中直接指定转接地址 proxy_set_header Host geo.datav.aliyun.com;
3、手动设置dns，resolver 8.8.8.8;
