Cookie只能通过特定的URL访问 [英] Cookie accessible only by specific URL

问题描述

我想使用javascript获取和设置cookie，但只希望对其进行设置的页面可以访问它们(即cookie对页面是私有的，因此没有其他页面可以干扰或读取它们).

I want to get and set the cookie using javascript, but want them only to be accessible to the page that set them (i.e the cookie is private to the page, so no other pages can interfere or read them).

推荐答案

这是您需要做的:

假设您在页面上，网址为 http://www.example.com/pages/myPage.html ，并且仅在设置/创建您拥有的Cookie时，您才想限制对此特定页面( myPage.html )上Cookie的访问设置路径参数为当前页面相对路径.

Suppose you are on the page with url http://www.example.com/pages/myPage.html, and you want to limit the access to cookies on this particular page (myPage.html) only then while setting/creating the cookie you have the set the path parameter as current page relative path.

var pathToMyPage = window.location.pathname; // this gives pages/myPage.html
document.cookie('name=value;path='+ pathToMyPage); 

现在，如果您尝试在其他页面的cookie中查找此特定键，请说/pages/myPage2.html .您不会在那找到它.

Now if you try to look for this particular key in the cookie of other pages say /pages/myPage2.html. You won't find it there.
