Is there any way to detect HTTP or HTTPS and then force usage of HTTPS with JavaScript?
I have some codes for detecting the HTTP or HTTPS but I can't force it to use https:
.
I'm using the window.location.protocol property to set whatever the site is to https:
then refresh the page to hopefully reload a new https'ed URL loaded into the browser.
if (window.location.protocol != "https:") {
window.location.protocol = "https:";
window.location.reload();
}
This question is related to
javascript
https
window.location
I like the answers for this question. But to be creative, I would like to share one more way:
<script>if (document.URL.substring(0,5) == "http:") window.location.replace('https:' + document.URL.substring(5));</script>
You can do:
<script type="text/javascript">
if (window.location.protocol != "https:") {
window.location.protocol = "https";
}
</script>
The below code assumes that the variable 'str' contains your http://.... string. It checks to see if it is https and if true does nothing. However if it is http it replaces http with https.
if (str.indexOf('https') === -1) {
str = str.replace('http', 'https')
}

Hi i used this solution works perfectly.No Need to check, just use https.
<script language="javascript" type="text/javascript">
document.location="https:" + window.location.href.substring(window.location.protocol.length, window.location.href.length);
</script>
It is not good idea because you just temporary redirect user to https and browser doesn't save this redirect.
You describe task for web-server (apache, nginx etc) http 301, http 302
How about this?
if (window.location.protocol !== 'https:') {
window.location = 'https://' + window.location.hostname + window.location.pathname + window.location.hash;
}
Ideally you'd do it on the server side, though.
I have just had all the script variations tested by Pui Cdm, included answers above and many others using php, htaccess, server configuration, and Javascript, the results are that the script
<script type="text/javascript">
function showProtocall() {
if (window.location.protocol != "https") {
window.location = "https://" + window.location.href.substring(window.location.protocol.length, window.location.href.length);
window.location.reload();
}
}
showProtocall();
</script>
provided by vivek-srivastava works best and you can add further security in java script.
Setting location.protocol navigates to a new URL. No need to parse/slice anything.
if (location.protocol !== "https:") {
location.protocol = "https:";
}
Firefox 49 has a bug where https
works but https:
does not. Said to be fixed in Firefox 54.
Functional way
window.location.protocol === 'http:' && (location.href = location.href.replace(/^http:/, 'https:'));
Not a Javascript way to answer this but if you use CloudFlare you can write page rules that redirect the user much faster to HTTPS and it's free. Looks like this in CloudFlare's Page Rules:
You should check this: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Security-Policy/upgrade-insecure-requests
Add this meta tag to your index.html inside head
<meta http-equiv="Content-Security-Policy" content="upgrade-insecure-requests">
Hope it helped.
if (location.protocol == 'http:')
location.href = location.href.replace(/^http:/, 'https:')
