java - 从 MessageContext.HTTP_RESPONSE_HEADERS 获取 Cookie 值

Question

如何从 cookie 列表中获取特定 cookie 的值。以下是我的尝试：

        Map<String, List<String>> map = (Map<String, 
                List<String>>) context.get(MessageContext.HTTP_RESPONSE_HEADERS);

        List<String> contentType = getHTTPHeader(map);
        if (contentType != null) {
            StringBuffer strBuf = new StringBuffer();
            for (String type : contentType) {
                strBuf.append(type);
            }
            System.out.println("Content-Type:" + strBuf.toString());
        }

        List<String> cookies = map.get("Set-Cookie"); 
        if (cookies != null) {
            System.out.println("cookies != null");
            StringBuffer strBuf = new StringBuffer();
            for (String type : cookies) {
                System.out.println(" Looping cookie ");
                strBuf.append(type);
            }
            System.out.println("Cookie:" + strBuf.toString());
        }else{
            System.out.println("cookies == null");
        }

我得到以下结果，我想获得“JSESSIONID”的价值

Cookie:JSESSIONID=88E53DE2E78TRE86E1C2B021BA240B; Path=/us-webservice

谢谢。

Answer 1

cookie.substring(cookie.indexOf(':'), cookie.indexOf(';')).split("=")[1]

或者如果你想要正则表达式

Pattern p = Pattern.compile( "JSESSIONID=([A-Z0-9]+)");
Matcher m = p.matcher(cookie);
m.find();
m.group(1);
