首先通過下面的鏈接下載openSSL
https://slproweb.com/products/Win32OpenSSL.html

下載完畢后，執(zhí)行openssl進入交互式界面：

使用命令生成privatekey.pem 1024意思是1024位長度。

openssl genrsa -out privatekey.pem 1024

生成的privatekey.pem，打開看一看長啥樣：

什么是pem文件？

.pem - Defined in RFCs 1421 through 1424, this is a container format that may include just the public certificate (such as with Apache installs, and CA certificate files /etc/ssl/certs), or may include an entire certificate chain including public key, private key, and root certificates. Confusingly, it may also encode a CSR (e.g. as used here) as the PKCS10 format can be translated into PEM. The name is from Privacy Enhanced Mail (PEM), a failed method for secure email but the container format it used lives on, and is a base64 translation of the x509 ASN.1 keys.

簡單的說，就是一個密鑰文件。

第二步，基于第一步生成的密鑰文件生成一個證書請求：
openssl req -new -key privatekey.pem -out certrequest.csr

如果懶得維護證書明細(xì)，直接敲回車，會自動填入默認(rèn)值：

最后基于第一步生成的密鑰和證書請求生成一個數(shù)字證書：當(dāng)然頒發(fā)機構(gòu)就是自己了，僅用于測試目的。
openssl x509 -req -in certrequest.csr -signkey privatekey.pem -out certificate.pem

至此我們有了privatekey.pem和Certificate.pem兩個證書了。

下面是我https服務(wù)器的代碼，很簡單，只有50幾行：

var app = require('express')(); var fs = require('fs'); var https = require('https');var httpOptions = {key: fs.readFileSync("keys/privatekey.pem"),cert: fs.readFileSync("keys/certificate.pem") }var server = https.createServer(httpOptions, app); var io = require('socket.io')(server);console.log("https server listens on port 8080...");server.listen(8080);function print_env(){console.log(process.env); }app.get('/', function (req, res) {var response = "Hello World";res.send(response); });app.get('/env', function (req, res) {print_env();// res.sendFile(__dirname + '/index.html');var response = JSON.stringify(process.env);res.send(response); });app.get('/redis', function (req, res) {var redisClient = require("./redisClient");function callback(response){// var response = "ok";//JSON.stringify(process.env);res.send(response);}redisClient.test(callback); });io.on('connection', function (socket) {console.log("connect comming from client: " + socket.id);socket.emit('messages_jerry', { hello: 'world greeting from Server!' });socket.on('messages', function (data) {console.log("data received from Client:" + JSON.stringify(data,2,2));}); });

從代碼里不難理解這兩個pem文件是如何用在https服務(wù)器里的。
最后在瀏覽器里測試。因為是自己頒發(fā)的證書，沒有經(jīng)過CA驗證，所以瀏覽器會顯示一個警告。
