node.js搭建web本地服务器

基于 node.js 搭建的临时服务器，可用于临时资源获取，简单业务处理

导包：

npm i http

npm i url

/** 读取文件 */
npm i fs

npm i path

自己定义的返回类型

/** 自定义类型 */
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",
  "zip": "application/zip",
  "xml": "text/xml"
};

var PORT = 7171; // 自定义端口

var http = require('http');
var url = require('url');
var fs = require('fs');
var path = require('path');
var mine = require('./mine').types;

var server = http.createServer(function (request, response) {
    
    
    var pathname = url.parse(request.url).pathname;
    var realPath = path.join("assets", pathname);
    console.log(realPath); // 打印请求的资源路径
    var ext = path.extname(realPath);
    ext = ext ? ext.slice(1) : 'unknown';
    fs.exists(realPath, function (exists) {
        if (!exists) {
            response.writeHead(404, {
                'Content-Type': "application/json;charset=utf-8"
            });
            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': "application/json;charset=utf-8"
                    });
                    response.end(err);
                } else {
                    var contentType = mine[ext] || "text/plain";
                    /** 配置跨域 */
                    response.writeHead(200, {
                        'Content-Type': contentType,
                        'Access-Control-Allow-Origin': '*',
                        "Access-Control-Request-Method": '*',
                        'Access-Control-Allow-Headers': '*'
                    });
                    response.write(file, "binary");
                    response.end();
                }
            });
        }
    });
});

console.log(server);
server.listen(PORT); // 运行 脚本、监听 post 端口
console.log("Server runing at port: " + PORT + ". lxyy"); // 成功输出日志

命令行执行 node index.js
