php和JS 判断http还是https，以及获得当前url的方法

$http_type = ((isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on') || (isset($_SERVER['HTTP_X_FORWARDED_PROTO']) && $_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https')) ? 'https://' : 'http://';
echo $http_type . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']; ?>

1、php判断http请求还是https请求

/**

* PHP判断当前协议是否为HTTPS
*/
function is_https() {
if ( !empty($_SERVER['HTTPS']) && strtolower($_SERVER['HTTPS']) !== 'off') {
return true;
} elseif ( isset($_SERVER['HTTP_X_FORWARDED_PROTO']) && $_SERVER['HTTP_X_FORWARDED_PROTO'] === 'https' ) {
return true;
} elseif ( !empty($_SERVER['HTTP_FRONT_END_HTTPS']) && strtolower($_SERVER['HTTP_FRONT_END_HTTPS']) !== 'off') {
return true;
}
return false;
}

调用:

$http_type = $this->is_https();
if($http_type){
echo "是https";
}else{

echo "是http";
}

2、 js判断http请求还是https请求

var ishttps = 'https:' == document.location.protocol ? true: false;
if(ishttps){
alert('https');
}else{
alert('http');
}
