如何从 JAVA 中的给定路径获取 cookie？

Question

我们如何从给定路径获取 cookie？当我们执行 request.getCookies() 时，默认情况下它从“\”中提取 cookie。但如果我想从给定路径获取它，假设“\bin\test”。这种情况下我们该怎么办？

您需要按路径滚动您自己的 cookie 过滤器

http://docs.oracle.com/javaee/1.4/api/javax/servlet/http/HttpServletRequest.html?is-external=true#getCookies()
http://docs.oracle.com/javaee/5/api/javax/servlet/http/Cookie.html
In a Java Servlet how can I change the value of an existing cookie?

List<Cookie> getCookiesFromPath(@Nonnull SlingHttpServletRequest request, String path) {
    Cookie[] allCookies = request.getCookies();

    if (path == null || path.isEmpty()) { // convert cookie array to cookie list
        return Arrays.asList(allCookies);
    }

    List<Cookie> cookieList = new ArrayList<Cookie>();
    for (Cookie c :  allCookies) {
        if (c.getPath().equals(path)) { // or equals()
            cookieList.add(c);
        }
    }
    return cookieList;
}
