问题描述

公司内建了业务服务器，对外提供web服务（IP+PORT），但是需要对接微信公众号，目前微信公共号只支持80，而内网众所周知的原因无法对外提供该端口。那么如何能完成业务验证和对接呢。

问题分析

1、企业进行域名备案，再更改业务端口，即可解决

2、使用Nginx反向代理实现业务代理。（本教程主要讲讲这种方法）

解决方法

1、打开nginx的配置文件nginx.conf，并进行编辑。

worker_processes auto;
error_log  logs/error.log;
events {
    worker_connections  1024;
}
http
    {
        include       mime.types;
        default_type  application/octet-stream;
        server_names_hash_bucket_size 512;
        client_header_buffer_size 32k;
        large_client_header_buffers 4 32k;
        client_max_body_size 50m;
        sendfile   on;
        tcp_nopush on;
        keepalive_timeout 60;
        tcp_nodelay on;

        fastcgi_connect_timeout 300;
        fastcgi_send_timeout 300;
        fastcgi_read_timeout 300;
        fastcgi_buffer_size 64k;

        fastcgi_busy_buffers_size 128k;
        fastcgi_temp_file_write_size 256k;
		fastcgi_intercept_errors on;

        gzip on;
        gzip_min_length  1k;
        gzip_buffers     4 16k;
        gzip_http_version 1.1;
        gzip_comp_level 2;
        gzip_types     text/plain application/javascript application/x-javascript text/javascript text/css application/xml;
        gzip_vary on;
        gzip_proxied   expired no-cache no-store private auth;
        gzip_disable   "MSIE [1-6]\.";

        limit_conn_zone $binary_remote_addr zone=perip:10m;
		limit_conn_zone $server_name zone=perserver:10m;

        server_tokens off;
        access_log off;
   
    server
        {
            listen 80;
            server_name wx.77bx.com;
            access_log  /logs/access/wx.77bx.com.log;
            error_log  /logs/error/wx.77bx.com.log;

            location / {
                index index.html;
                proxy_pass http://web.77bx.com:88;
                proxy_redirect off;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header Host $host;
                proxy_set_header X-Forwarded-proto https;
            }
        }
    server
        {
            listen 443;
            server_name wx.77bx.com;
            access_log  /logs/access/wx.77bx.com.log;
            error_log  /logs/error/wx.77bx.com.log;

            ssl on;
            ssl_certificate /cert/wx.77bx.com/server.crt;
            ssl_certificate_key /cert/wx.77bx.com/server.key;
            
            location / {
                index index.html;
                proxy_pass http://web.77bx.com:88;
                proxy_redirect off;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_set_header Host $host;
                proxy_set_header X-Forwarded-proto https;
            }
        }
}

这样就简单实现了反向代理，如果有复杂的业务还需要具体配置。
