Express的HTTP重定向到HTTPS的方法

作者：袖梨 2022-06-25

我本地测试时, HTTP使用3000端口, HTTPS使用443.

同时监听HTTP和HTTPS

转发所有GET请求

httpApp.get("*", (req, res, next) => {
  let host = req.headers.host;
  host = host.replace(/:d+$/, ''); // Remove port number
  res.redirect(`https://${host}${req.path}`);
});

相当于自己拼接上https的链接然后redirect. 此时浏览器会收到302 (MOVED_TEMPORARILY)状态码, 并重定向到HTTPS.

转发所有请求

httpApp.all("*", (req, res, next) => {
  let host = req.headers.host;
  host = host.replace(/:d+$/, ''); // Remove port number
  res.redirect(307, `https://${host}${req.path}`);
});

注意这里面有两个修改:
