将 Java cookie 对象转换为字符串以在 httpResponse "Set-Cookie" 标头中设置

Question

We originally used Java's HttpsServletResponse's addCookie(Cookie cookie) method to add a self-created cookie to our servlet response object. Due to some issues, I want to change this to explicitly set the cookie using addHeader("Set-Cookie", cookieStr) . The cookie is constructed by passing fields to a cookie object, and I wanted to know if I can use that object to just spit out a string. When I call .toString() on the cookie object, it just gives me the object reference. I know I can just construct the string, but since I already have the object, I wanted to know if there was a simple method I could call on the cookie object to parse it to a string, rather than create it myself.

Answer 1

The Cookie class has no such method.

You could take a look at an existing implementation to judge whether you want to do that yourself. Take a look at the Rfc6265CookieProcessor from Apache Tomcat. A more simple and less complete approach is here . That's quite some effort.

The better way is probably to solve the issues you had with the addCookie(Cookie cookie) method.
