在java中添加cookie，然后HTTP重定向不在客户端显示cookie [英] Adding cookie in java and then HTTP redirect doesnt show cookie in client side

问题描述

我有要求我在哪里需要在java中添加cookie，然后重定向到不同的URL。现在这个url进程应该保持我设置的cookie，并在其处理后发送回客户端。代码如下

I have requirement where in i need to add cookie in java and then redirect it to different URL. Now this url process should persist the cookie which i set and after its processing send it back to client. The code goes as follows

Cookie cookie = new Cookie("name", "value")
// To make sure cookie is established for all the url paths
cookie.setPath(request.getContextPath());
response.addCookie(cookie);
response.sendRedirect("someNewUrl");

请帮助我如何在整个重定向生命周期和客户端保持cookie。提前感谢。

Please help me regarding how can i persist the cookie throughout the redirect lifecycle and to the client. Thanks in advance.

推荐答案

尝试实际将添加到响应中

Try to actually add the cookie to the response:

Cookie cookie = new Cookie("user", "anonymous");
response.addCookie(cookie);

另请参阅：

• javax.servlet.http.HttpServletResponse.addCookie（javax.servlet.http.Cookie）

• javax.servlet.http.HttpServletResponse.addCookie(javax.servlet.http.Cookie)
