linux express配置ssl证书，开启https访问

1.下载ssl证书的Nginx版本，在项目根目录新建https空文件夹，把crt文件和key文件复制到https文件夹中;

2.安装依赖：npm i fs http https

3.修改www文件的内容：

var https = require('https');

var fs = require('fs');

var path = require('path');

 

var privateCrt = fs.readFileSync(path.join(process.cwd(), 'https/xxxx.crt'), 'utf8');

var privateKey = fs.readFileSync(path.join(process.cwd(), 'https/xxxx.key'), 'utf8');

const HTTPS_OPTOIN = {

  key: privateKey,

  cert: privateCrt

};

/**

 * Get port from environment and store in Express.

 */

var port = normalizePort(process.env.PORT || '8000');

app.set('port', port);

/**

 * Create HTTP server.

 */

var server = https.createServer(HTTPS_OPTOIN,app);
