详解本地Node.js服务器作为api服务器的解决办法

 //服务器端的代码var express = require('express');var app = express();// set up handlebars view enginevar handlebars = require('express3-handlebars')  .create({ defaultLayout:'main' });app.engine('handlebars', handlebars.engine);app.set('view engine', 'handlebars');app.set('port', process.env.PORT || 3000);app.use(express.static(__dirname + '/public'));var fortuneCookies = [  "Conquer your fears or they will conquer you.",  "Rivers need springs.",  "Do not fear what you don't know.",  "You will have a pleasant surprise.",  "Whenever possible, keep it simple.",];app.get('/', function(req, res) {  res.render('home');});app.get('/about', function(req,res){  var randomFortune =     fortuneCookies[Math.floor(Math.random() * fortuneCookies.length)];  res.render('about', { fortune: randomFortune });});// 404 catch-all handler (middleware)app.use(function(req, res, next){  res.status(404);  res.render('404');});// 500 error handler (middleware)app.use(function(err, req, res, next){  console.error(err.stack);  res.status(500);  res.render('500');});app.listen(app.get('port'), function(){ console.log( 'Express started on http://localhost:' +   app.get('port') + '; press Ctrl-C to terminate.' );});

//proxy.js  var http = require('http'),      httpProxy = require('http-proxy'); //引入这个模块// 新建一个代理 Proxy Server 对象 var proxy = httpProxy.createProxyServer({}); // 捕获异常 proxy.on('error', function (err, req, res) {  res.writeHead(500, {   'Content-Type': 'text/plain'  });  res.end('Something went wrong. And we are reporting a custom error message.'); }); // 另外新建一个 HTTP 80 端口的服务器，也就是常规 Node 创建 HTTP 服务器的方法。 // 在每次请求中，调用 proxy.web(req, res config) 方法进行请求分发 var server = require('http').createServer(function(req, res) {  // 在这里可以自定义你的路由分发  var host = req.headers.host, ip = req.headers['x-forwarded-for'] || req.connection.remoteAddress;  console.log("client ip:" + ip + ", host:" + host);  switch(host){ //意思是监听下面的ip地址,如果匹配就转到//127.0.0.1:3000地址  case '192.168.0.101:8080':  //监听这个地址  //这个地址在window上用ipconfig查看,mac/linux用ifconfig查看  case 'bbs.aaaa.com':     proxy.web(req, res, { target: 'http://127.0.0.1:3000' }); //转到这个地址  break;   default:     res.writeHead(200, {       'Content-Type': 'text/plain'     });     res.end('Welcome to my server!');  } }); console.log("listening on port 8080") server.listen(8080);

 //nginx.conf #原来的文件另存后。直接使用下面内容替换nginx.conf的内容events {  worker_connections 1024;}http {  include    mime.types;  default_type application/octet-stream;  #log_format main '$remote_addr - $remote_user [$time_local] "$request" '  #         '$status $body_bytes_sent "$http_referer" '  #         '"$http_user_agent" "$http_x_forwarded_for"';  sendfile    on;  #tcp_nopush   on;  #keepalive_timeout 0;  keepalive_timeout 65;  server {    listen 8080; #监听80880端口    server_name www.penguu.com 192.168.1.100; #这里是真机要访问的地址。    # Mac 通过终端 ifconfig 查看。比如我查看的就是192.168.1.100    #手机访问的接口就是 192.168.1.100:8080    #实际在23行监听的端口可以是80端口，由于浏览器默认就是80端口。但是在mac中有权限问题。所#以就使用8080端口    # address_book中的service中的地址也要修改路径是    # view/service.js->host,修改为 192.168.1.100：8080    #access_log /var/log/nginx/test.log;    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_set_header X-Nginx-Proxy true;      proxy_set_header Connection "";      proxy_pass   http://127.0.0.1:3000; # address_book的 server地址，就是本地node.js服务器的ip地址      #node.js默认就是127.0.0.1 ，port:3000是在app.js中设定的。可以修改。    }  }  }
