如何在servlet中调用javascript cookie？

Question

我尝试过从javascript到servlet的cookie

request.getcookie()

方法.但我发现该值为null.

有没有办法从javascript到servlet获取cookie？

Answer 1

尝试这个

Cookie[] cookies = request.getCookies();


for (int i = 0; i < cookies.length; i++) {
    Cookie c = cookies[i];
     c.getName()  //cookie name
    c.getValue()   //cookie value

  }
