如何利用node.js配置自签名https服务器

openssl genrsa 1024 > /pathway/private.pem

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

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

var express = require('express'); // 项目服务端使用express框架
var app = express();
var path = require('path');
var fs = require('fs');

//使用nodejs自带的http、https模块
var http = require('http');
var https = require('https');

//根据项目的路径导入生成的证书文件
var privateKey  = fs.readFileSync(path.join(__dirname, './certificate/private.pem'), 'utf8');
var certificate = fs.readFileSync(path.join(__dirname, './certificate/file.crt'), 'utf8');
var credentials = {key: privateKey, cert: certificate};

var httpServer = http.createServer(app);
var httpsServer = https.createServer(credentials, app);

//可以分别设置http、https的访问端口号
var PORT = 8000;
var SSLPORT = 8001;

//创建http服务器
httpServer.listen(PORT, function() {
    console.log('HTTP Server is running on: http://localhost:%s', PORT);
});

//创建https服务器
httpsServer.listen(SSLPORT, function() {
    console.log('HTTPS Server is running on: https://localhost:%s', SSLPORT);
});

//可以根据请求判断是http还是https
app.get('/', function (req, res) {
    if(req.protocol === 'https') {
        res.status(200).send('This is https visit!');
    }
    else {
        res.status(200).send('This is http visit!');
    }
});
