我们先收集不同浏览器的
HTTP_USER_AGENT
此方法可以用PHP或是JS来收集
PHP
<?php echo $_SERVER['HTTP_USER_AGENT']; ?>
JS
<!DOCtype html>
<html>
<head>
<title></title>
</head>
<body οnlοad="whatBrowser()">
<script>
function whatBrowser() {
document.Browser.Name.value=navigator.appName;
document.Browser.Version.value=navigator.appVersion;
document.Browser.Code.value=navigator.appCodeName;
document.Browser.Agent.value=navigator.userAgent;
}
</script>
