nodeJs+http-proxy 搭建代理服务器

node本地安装位置： C:\Program Files (x86)\nodejs

代理服务器搭建

cmd：

cd   项目目录

cnpm install http-proxy --save-dev

npm init    // 创建项目



node proxy.js   // 进入项目目录 - cmd  启动项目

 

npm init

 

 

项目启动效果：

 

 

接口跨域 访问失败：

 

404解决办法：

请求是404问题解决啦：

pathname.indexOf("mspj-mall-admin")；这段代码的问题

'mspj-mall-admin' 是请求接口某个固定字段

如接口 /api/sysUnit/list

就可以写成 pathname.indexOf("api")；

 

 

代码整理如下：

node系统结构：

proxy.js: 启动文件配置

var PORT = 3000;



var http = require('http');

var url=require('url');

var fs=require('fs');

var mine=require('./mine').types;

var path=require('path');

var httpProxy = require('http-proxy');



var proxy = httpProxy.createProxyServer({

    target: 'http://172.18.19.24:8080/',   //接口地址

    changeOrigin: true,

    // 下面的设置用于https

    // ssl: {

    //     key: fs.readFileSync('server_decrypt.key', 'utf8'),

    //     cert: fs.readFileSync('server.crt', 'utf8')

    // },

    // secure: false

});



proxy.on('error', function(err, req, res){

    res.writeHead(500, {

        'content-type': 'text/plain'

    });

    console.log(err);

    res.end('Something went wrong. And we are reporting a custom error message.');

});



var server = http.createServer(function (request, response) {

    var pathname = url.parse(request.url).pathname;

    //var realPath = path.join("main-pages", pathname); // 指定根目录

    var realPath = path.join("./", pathname);

    console.log(pathname);

    console.log(realPath);

    var ext = path.extname(realPath);

    ext = ext ? ext.slice(1) : 'unknown';



    //判断如果是接口访问，则通过proxy转发

    if(pathname.indexOf("hiiap") > 0){

        proxy.web(request, response);

        return;

    }



    fs.exists(realPath, function (exists) {

        if (!exists) {

            response.writeHead(404, {

                'Content-Type': 'text/plain'

            });



            response.write("This request URL " + pathname + " was not found on this server.");

            response.end();

        } else {

            fs.readFile(realPath, "binary", function (err, file) {

                if (err) {

                    response.writeHead(500, {

                        'Content-Type': 'text/plain'

                    });

                    response.end(err);

                } else {

                    var contentType = mine[ext] || "text/plain";

                    response.writeHead(200, {

                        'Content-Type': contentType

                    });

                    response.write(file, "binary");

                    response.end();

                }

            });

        }

    });

});

server.listen(PORT);

console.log("Server runing at port: " + PORT + ".");
