是这里的正则出了错 https://github.com/alist-org/alist/blob/5e59b0a697e3b65df151104e8f4f8c07b25e29b5/drivers/lanzou/lanzou.go#L213

蓝奏云的网页源码又改了：

<script type="text/javascript">
		var ajaxdata = '?ctdf';
		var cwebsignkeyc = '66xM';
		var awebsigna = '';
		var vsign = 'AmRTbQw9UmNSWws0UGAHOwdqUmBXOAMzUWIENgFsADQCJFZ1C2sPalU1AWJQPVJmWjhUZF80Vm0LOg_c_c';
		//var ispostdowns = '';
		$.ajax({
			type : 'post',
			url : '/ajaxm.php',
			//data : { 'action':'downprocess','signs':ajaxdata,'sign':'sign','ves':1,'websign':websign,'websignkey':websignkey },
			data : { 'action':'downprocess','signs':ajaxdata,'sign':vsign,'websign':awebsigna,'websignkey':cwebsignkeyc,'ves':1 },
			dataType : 'json',
			success:function(msg){
				var date = msg;
				if(date.zt == '1'){
										$("#go").html("<a href="+date.dom+"/file/"+ date.url +" target=_blank rel=noreferrer><span class=txt>电信下载</span><span class='txt txtc'>联通下载</span><span class=txt>普通下载</span></a>");
					setTimeout('$("#outime").css("display","block");',1800000);
									}else{
					$("#go").html("网页超时，请刷新");
				};
				
			},
			error:function(){
				$("#go").html("获取失败，请刷新");
			}
	
		});
</script>

应该把websignkey改成cwebsignkeyc就行
