Java 等效於 C# HttpContext

Question

什么是 C# 中的 HttpContext 等效的 Java？ 我需要將以下內容轉換為 Java。 這段代碼基本上是在提取一個 cookie。

// This method returns the username from the login cookie, or null if no user is logged in.
public string ExtractUser(HttpContext context)
{
   // Get the correct cookie from the request
   var Cookie = context.Request.Cookies["dummyUser"];
 
   // Return the cookie's value if it exists
   if ((Cookie != null) && (Cookie.Value != null))
      return Cookie.Value;
 
   // Return null otherwise
   return null;
}

試試HttpServletRequest看這里getCookies()方法

public static String getCookie(HttpServletRequest req,String name) {
  Cookie[] cookies = req.getCookies();
  if(cookies!=null) {
    for (Cookie cookie : cookies) {
      if(cookie.getName().equals(name)) {
        return cookie.getValue();
      }
    }
  }
  return null;
}
