微信errMsg: "config:invalid signature"

server {
        listen       80;
        server_name  localhost.com;

        location / {
            proxy_set_header  X-Real-IP  $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Host $http_host;
            proxy_redirect off;
        }
    }

加入這幾項配置

proxy_set_header  X-Real-IP  $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
