1, the use Package.json installs the Nodejs, creates the Package.json file: The content is as follows

"Dependencies": {
  "Http-proxy": "^1.16.2"
}

2. Create index.js file Under current directory: content as follows
var PORT = 3000;
var ProjectPath = '/'.  /project '; Local Project Path

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/',//interface address
The following settings are used for 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); Specify the root directory
Console.log (pathname);
var Realpath = Path.join (".") +projectpath+ '/', pathname);
var ext = path.extname (Realpath);
Ext = ext? Ext.slice (1): ' Unknown ';

Determine if the interface is accessed by proxy forwarding
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 + "is not found on the 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, as index.js the second line is configured: Create a project folder in the top directory of the current directory projects
put index.html test page

<! DOCTYPE html>
<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>
<body>
1111
</body>

4. CNPM Install

5, Node Index.js Open 3000 Service

6, Note: mine.js content:
