近日在尝试运行之前一直都成功撷取网页内容的脚本时，突然跑出下面的错误。是否指被人封阻了内容撷取了？
<html>
<head>
<script>
Challenge=305158;
ChallengeId=395740057;
GenericErrorMessageCookies="Cookies must be enabled in order to view this page.";
</script>
<script>
function test(var1)
{
var var_str=""+Challenge;
var var_arr=var_str.split("");
var LastDig=var_arr.reverse()[0];
var minDig=var_arr.sort()[0];
var subvar1 = (2 * (var_arr[2]))+(var_arr[1]*1);
var subvar2 = (2 * var_arr[2])+var_arr[1];
var my_pow=Math.pow(((var_arr[0]*1)+2),var_arr[1]);
var x=(var1*3+subvar1)*1;
var y=Math.cos(Math.PI*subvar2);
var answer=x*y;
answer-=my_pow*1;
answer+=(minDig*1)-(LastDig*1);
answer=answer+subvar2;
return answer;
}
</script>
