automatic redirection to https?
提问by LanceBaynes
if i use:
如果我使用：
<meta http-equiv="REFRESH" content="0;url=https://www.the-domain-you-want-to-redirect-to.com/index.html">
<meta http-equiv="REFRESH" content="0;url=https://www.the-domain-you-want-to-redirect-to.com/index.html">
in the html code then it will endlessly loop and refresh the https page.
在 html 代码中，它将无休止地循环并刷新 https 页面。

var loc = window.location.href+'';
if (loc.indexOf('http://')==0){
window.location.href = loc.replace('http://','https://');
}
maybe? as long as you don't mind a small javascript dependency.
也许？只要你不介意小的 javascript 依赖。

This could be more elegant
这可能更优雅
if(/https/.test(window.location.protocol)){
window.location.href = window.location.href.replace('http:', 'https:');
}
However, this is an answer in a code level. To answer the question a bit more broadly, it is even possible to not even touch the code for that, like in the network level or in the application level.
但是，这是代码级别的答案。更广泛地回答这个问题，甚至可以不触及代码，例如在网络级别或应用程序级别。
In the network level, you can use an edge router like Traefik. In the application level, you can use a reverse proxy for the redirection. Reverse proxies like Ngnix or services like Cloudflare or AWS Cloudfront.
在网络层面，可以使用像 Traefik 这样的边缘路由器。在应用层，可以使用反向代理进行重定向。反向代理（如 Ngnix）或服务（如 Cloudflare 或 AWS Cloudfront）。
Also note that in case you host your website on platforms like Firebase Hosting, you will have the automatic redirection to https by default.
另请注意，如果您在 Firebase Hosting 等平台上托管您的网站，默认情况下您将自动重定向到 https。
