Nodejs创建https服务器(Windows 7)

为了实验一下WebRTC，搭了个简单的https服务器。说说步骤：

1. 生成OpenSSL证书
2. 使用Nodejs的https模块建立服务器

OpenSSL 证书

我机子Windows 7，安装了Cygwin，里面安装了openssl，我用它来生成https服务器需要的证书文件。

1. 生成私钥key文件

$ openssl genrsa -out privatekey.pem 1024

Generating RSA private key, 1024 bit long modulus
....++++++
.....................................++++++
e is 65537 (0x10001)

2. 通过私钥生成CSR证书签名

$ openssl req -new -key privatekey.pem -out certrequest.csr

You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
-----
Country Name (2 letter code) [AU]:CN
State or Province Name (full name) [Some-State]:ShanXi
Locality Name (eg, city) []:Xian
Organization Name (eg, company) [Internet Widgits Pty Ltd]:foruok
Organizational Unit Name (eg, section) []:foruok
Common Name (e.g. server FQDN or YOUR name) []:foruok
Email Address []:foruok@163.com

Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:

3. 通过私钥和证书签名生成证书文件

$ openssl x509 -req -in certrequest.csr -signkey privatekey.pem -out certification.pem

Signature ok
subject=/C=CN/ST=ShanXi/L=Xian/O=foruok/OU=foruok/CN=foruok/emailAddress=foruok@163.com
Getting Private key

Nodejs https 服务器示例

从Nodejs文档里摘出来的代码：

    const https = require('https');
    const fs = require('fs');

    const options = {
        key: fs.readFileSync('./privatekey.pem'),
        cert: fs.readFileSync('./certification.pem')
    };

    https.createServer(options, (req, res) => {
        res.writeHead(200);
        res.end('hello world\n');
    }).listen(8000);

执行 node httpsdemo.js，然后在Chrome里访问access https://192.168.40.158:8000。结果如下：

你可能注意到了，证书有点问题，点下地址栏，能看怎么回事儿：

我们创建的证书没有经过身份验证，不受信。有需要的话，可以去有资质的网络运营商申请自己的证书。
