nginx配置无法正常访问设置返回json数据

将错误码单独添加到一个配置文件中

vi ./host/error.conf

proxy_intercept_errors on;
location error_page 502 {
      default_type application/json;
     return 500 '{"msg":"服务正在重启...","code": 500,"data":null}';
}

location error_page 504 {
     default_type application/json;
     return 500 '{"msg":"请求超时...","code": 500,"data":null}';
}

在nginx中引入error.conf

include ./host/error.conf

重启nginx:

systemctl restart nginx
