nodejs的express框架建立https服务器

一 openssl建立https私钥和证书

1.下载windows版openssl:

http://slproweb.com/products/Win32OpenSSL.html

Win64OpenSSL_Light-1_1_1b.exe

2.安装并使用openssl:

2.1 正常安装openssl.exe

2.2 进入openssl安装目录的bin里面

＃生成私钥key文件

openssl genrsa 1024 > ./private.pem

＃经过私钥文件生成CSR证书签名

openssl req -new -key ./private.pem -out csr.pem

＃经过私钥文件和CSR证书签名生成证书文件

openssl x509 -req -days 365 -in csr.pem -signkey ./private.pem -out ./file.crt

 

二 windows下安装和使用express框架：

1.全局安装express框架,cmd打开命令行,输入以下命令:

        npm install -g express

   express 4.x版本中将命令工具分出来,安装一个命令工具,执行命令:

        npm install -g express-generator

     输入express --version验证

2.若是在执行js文件仍报Error: Cannot find module express错误。

解决办法：
    在本身的工程目录下再次执行:
        npm install express

三 建立https服务器

1.进入node项目下，拷贝私钥和证书到此目录下

2.建立node服务程序https.js:

var app = require('express')();
var fs = require('fs');
var http = require('http');
var https = require('https');
var privateKey  = fs.readFileSync('./private.pem', 'utf8');
var certificate = fs.readFileSync('./file.crt', 'utf8');
var credentials = {key: privateKey, cert: certificate};

var httpServer = http.createServer(app);
var httpsServer = https.createServer(credentials, app);
var PORT = 18080;
var SSLPORT = 18081;

httpServer.listen(PORT, function() {
    console.log('HTTP Server is running on: http://localhost:%s', PORT);
});
httpsServer.listen(SSLPORT, function() {
    console.log('HTTPS Server is running on: https://localhost:%s', SSLPORT);
});

// Welcome
app.get('/', function(req, res) {
    if(req.protocol === 'https') {
        res.status(200).send('Welcome to Safety Land!');
    }
    else {
        res.status(200).send('Welcome!');
    }
});

3.运行：node https.js

4.浏览器访问：https://localhost:18081/
