设置网页只允许在手机微信浏览器打开

只能在手机微信浏览器打开
js前端的代码

$(function(){
        var ua = navigator.userAgent.toLowerCase();
        var isWeixin = ua.indexOf('micromessenger') != -1;
        var isAndroid = ua.indexOf('android') != -1;
        var isIos = (ua.indexOf('iphone') != -1) || (ua.indexOf('ipad') != -1);
        if (!isWeixin) {
            document.head.innerHTML = '<title>抱歉，出错了</title><meta charset="utf-8"><meta name="viewport" content="width=device-width, initial-scale=1, user-scalable=0"><link rel="stylesheet" type="text/css" href="res.wx.qq/open/libs/weui/0.4.1/weui.css">';
            document.body.innerHTML = '<div class="weui_msg"><div class="weui_icon_area"><i class="weui_icon_info weui_icon_msg"></i></div><div class="weui_text_area"><h4 class="weui_msg_title">请在微信客户端打开链接</h4></div></div>';
             
        }else{
                var ok = /Android|webOS|iPhone|iPod|BlackBerry/i.test(navigator.userAgent);
                if(!ok){
                        window.location.href =  "www.baidu/";
                        //return false;
                }
        }
});

php的后端的代码

// 判断访问设备必须是微信浏览器，否则跳的微信的网页qq
$useragent = addslashes($request->server('HTTP_USER_AGENT'));
if(strpos($useragent, 'MicroMessenger') === false && strpos($useragent, 'Windows Phone') === false ){
    return redirect()->to(route('weChatBrowser'), 302);
}

整体的话，js的前端代码判断比较严格，但是php的代码可以源头上根除问题，防止代码泄露，建议两者都配置
