2019-01-03： NodeJS local https.md

local 測試時，使用 https

有些時候可能需要，例如我這次測試微信desktop時，要用內建的功能開啟網頁時，它只支援 https

產生 key

先在該目錄下，先產生 key （指令如下）

openssl req -nodes -new -x509 -keyout server.key -out server.cert

NodeJS 部分

除了 http 之外，另外起 https server 並 proxy 過去

const https = require('https');
const httpProxy = require('http-proxy');
const fs = require('fs');

const proxy = httpProxy.createProxyServer({});

https.createServer({
  key: fs.readFileSync('./server.key'), // 確認這目錄是上個步驟所產生的檔案
  cert: fs.readFileSync('./server.cert'), // Windows、Linux 的目錄位置可能不同
},
(req, res) => {
  proxy.web(req, res, {
    target: 'http://localhost:3014', // 指到 http server 的 位置去
  });
},
app)
.listen(8009, function () {})

最後這樣訪問

https://127.0.0.1:8009
