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
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8" />
<title>1111</title>
<script>
function readFile(a,back){
setTimeout(function(){
back(a);
},1000);
}
const Thunk = function(fn) {
return function (...args) {
return function (callback) {
return fn.call(this, ...args, callback);
}
};
};
var tf = Thunk(readFile);
var gg = {
*g(){
var f1 = yield tf(‘fileA‘);
console.log(‘---->>‘,f1);
var f2 = yield tf(‘fileB‘);
console.log(‘---->>‘,f2);
// if (f2=="fileB")
// return;
// ...
var fn = yield tf(‘fileN‘);
console.log(‘---->>‘,fn);
}
}
var g = function* () {
var f1 = yield tf(‘fileA‘);
console.log(‘---->>‘,f1);
var f2 = yield tf(‘fileB‘);
console.log(‘---->>‘,f2);
// if (f2=="fileB")
// return;
// ...
var fn = yield tf(‘fileN‘);
console.log(‘---->>‘,fn);
}
const run_thunk = function (fn) {
var gen = fn();
function next(err, data) {
var result = gen.next(err);
if (result.done) return;
result.value(next);
}
next();
}
function * a(){
yield 1;
yield 2;
}
var init = function(){
// run_thunk(gg.g);
var m = setTimeout(function(){
alert(‘hell‘);
},5000);
setTimeout(function(){
clearTimeout(m);
alert(‘111‘);
},1000);
// var i = a();
// console.log(i.next());
// console.log(i.next());
// console.log(i.next());
}
init();
</script>
</head>
<body>
1111
</body>
</html>
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
