解决ubantu下使用nginx 代理uwsgi服务的问题

问题:

在ubantu下部署服务,使用nginx对请求进行转发,之前使用一个服务时没有问题现在要求新加一个api,在修改配置文件之后报502错误

nginx 配置文件如下:

server {
    listen      80; # 监听80端口

    #root        /home/jsh/jsh/table/PaddleOCR-release-2.1/webserver; 
    server_name 39.101.190.228; # 配置域名
    
    charset utf-8;
    client_max_body_size 75M;
    # 处理静态资源:
    location / {
        root /root/python/wtableocr/webserver/html;
        index index.html;
   }

    # 动态请求转发到5000端口(uwsgis):
    location /rectable {
        #proxy_pass       http://127.0.0.1:5000/;
        #proxy_set_header X-Real-IP $remote_addr;
        #proxy_set_header Host $host;
        #proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                include uwsgi_params;
        uwsgi_param script_NAME /rectable;
        uwsgi_pass 127.0.0.1:5000;
        uwsgi_param UWSGI_PYHONE /root/miniconda3/envs/paddle/bin/python3;
        uwsgi_param UWSGI_CHDIR /root/python/wtableocr/webserver/;
        uwsgi_param UWSGI_script manage:app;
    }
    location /recidcard {
        uwsgi_param script_NAME /recidcard;
        uwsgi_pass 127.0.0.1:5000;
        uwsgi_param UWSGI_PYHONE /root/miniconda3/envs/paddle/bin/python3;
        uwsgi_param UWSGI_CHDIR /root/python/wtableocr/webserver/;
        uwsgi_param UWSGI_script manage:app;  
    }

} 

nginx错误日志如下:

通过观察发现是新加的路径没有添加:

 include uwsgi_params;

添加之后可以正常转发请求.
