nginx配置location多级路径访问

　　我原本项目访问路径是：

https://域名/项目名称/

　　需求是在上述路径不动的基础上，添加一个路径如下：

https://域名/A/项目名称/

方法是在443代理下添加如下：ipport、项目名称替换成自己的即可

        location /A/projectName {
            proxy_pass http://127.0.0.1:80/项目名称;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            client_max_body_size 10m;
            client_body_buffer_size 128k;
            proxy_connect_timeout 90;
            proxy_send_timeout 90;
            proxy_read_timeout 90;
            proxy_buffer_size 4k;
            proxy_buffers 4 32k;
            proxy_busy_buffers_size 64k;
            proxy_temp_file_write_size 64k;
        }

关键点是proxy_pass，当我设置成upstream server的时候无论怎么设置都无法正常工作。正常设置如下：

    upstream myserver{
       server 127.0.0.1:80;
    }
        location /naire2 {
            proxy_pass http://myserver;
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            client_max_body_size 10m;
            client_body_buffer_size 128k;
            proxy_connect_timeout 90;
            proxy_send_timeout 90;
            proxy_read_timeout 90;
            proxy_buffer_size 4k;
            proxy_buffers 4 32k;
            proxy_busy_buffers_size 64k;
            proxy_temp_file_write_size 64k;
        }
