在本地设置 http-proxy 代理 (前后端分离)

标签：开启   list   ini   wav   als   json   content   ide   wave   

　1、 利用package.json 安装nodejs，创建package.json文件：内容如下

"dependencies": {
  "http-proxy": "^1.16.2"
}
2、 当前目录下创建 index.js文件：内容如下

var PORT = 3000;
var projectPath = ‘/../project‘;  // 本地项目路径
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://192.168.12.220:8080/‘,   //接口地址
    // 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
    console.log(pathname);
    var realPath = path.join("."+projectPath+‘/‘, pathname);
    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("/deviceService") > -1){
        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 + ".");
３、 如 index.js 第二行所配置：在当前目录上层目录创建项目文件夹 project
放入index.html 测试页面

4、cnpm install

5、node index.js 开启3000服务

6、注：mine.js 内容：

exports.types = {
"css": "text/css",
"gif": "image/gif",
"html": "text/html",
"ico": "image/x-icon",
"jpeg": "image/jpeg",
"jpg": "image/jpeg",
"js": "text/javascript",
"json": "application/json",
"pdf": "application/pdf",
"png": "image/png",
"svg": "image/svg+xml",
"swf": "application/x-shockwave-flash",
"tiff": "image/tiff",
"txt": "text/plain",
"wav": "audio/x-wav",
"wma": "audio/x-ms-wma",
"wmv": "video/x-ms-wmv",
"xml": "text/xml",
"woff": "application/x-woff",
"woff2": "application/x-woff2",
"tff": "application/x-font-truetype",
"otf": "application/x-font-opentype",
"eot": "application/vnd.ms-fontobject"
};

项目结构：     -----  nodeServer

                              |---- package.json

                              |---- index.js

                              |---- mine.js

                              |---- node_modules

                      -----  project

                              |---- index.html
