node微信接入后台服务器

1.本地微信环境搭建（frp/路由器做端口映射）

--服务器frp配置并启动：./frps -c ./frps.ini & (注意：打开7000端口)

# frps.ini
[common]
bind_port = 7000
vhost_http_port = 8888

--客户端frp配置：start  ./frpc -c ./frpc.ini

# frpc.ini
[common]
server_addr = 39.108.139.60
server_port = 7000

[web]
type = http
local_port = 8888 #端口任意
custom_domains = maoriaty.top

注意：服务器端的http端口和客户端的http端口无关，所以更换端口只需修改客户端即可

--nginx配置：注意微信只接入80或443端口，所以nginx代理端口必须为80或443

#test local proxy
server
{
    listen 80;
    server_name t.maoriaty.top;

    expires 300d;
    gzip on;

    location / {
        proxy_pass  http://127.0.0.1:8888;
        proxy_redirect default;
        proxy_set_header Host $host; 
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

--创建.bat文件批处理启动本地服务器和链接：

cd /d "E:\JabinDOC\frp_0.13.0_windows_amd64"
start ./frpc -c ./frpc.ini

2.微信接入

--app.js接入文件

var express = require('express');
var crypto = require('crypto');
var config = {
    "AppId": 'wx1af02f9490ff3e98',
    "AppSecret": '92bd3a03d76da03abba6b7d1c25c23a7',
    "Token": 'maoriaty'
}

var app = express();

app.get('/',function(req,res){
    var signature = req.query.signature;
    var timestamp = req.query.timestamp;
    var nonce = req.query.nonce;
    var echostr = req.query.echostr;

    var str = [config.Token,timestamp,nonce].sort().join('');
    var sha1 = crypto.createHash('sha1').update(str,'utf-8').digest('hex');
    if(sha1 == signature){
        res.send(echostr);
    }else{
        res.send('err');
    }
    console.log(signature+'==='+sha1);
})

var server = app.listen('8888',function(){
    console.log('the port is %s',server.address().port);
})

--启动app.js然后微信后台接入即可

--如果不需验证加密，最简单可以如下：

// ====================微信接入====================  //
const app = require("express")(),
app.get('/',(req,res) => res.send(req.query.echostr;))
let server = app.listen(8888,() => console.log('the port is %s',server.address().port);
