需求：将Cookie字符串解析为Map集合 

 1、首先构造一个Cookie字符串

 private static String COOKIE = "traceid=ca4c9c8b50; _ga=GA1.2.704388932.1617513691; _gid=GA1.2.85700497.1617513691; _qpsvr_localtk=0.2810983015733952; RK=uCLoGvbeXG; ptcz=f997dfbd9d785b321bb377710933cae37308f34abb4b2340706eda53e23455cc; pgv_pvid=4861902100; pgv_info=ssid=s7567138318; ptui_loginuin=327844761; qqmusic_uin=0327844761; qqmusic_fromtag=6; qqmusic_key=@R3lRxCHCr; p_uin=o0327844761; _gat_gtag_UA_172919674_1=1; uin=o0327844761; skey=@APPCpl4ip; pt4_token=EWPb3WyZfLoQPIfmYfSjWDKOJXOIt09*xjIidJVdC54_; p_skey=6dlS-INlRzNbnEOA09*Zn2l6cfPMI4ardDbcWCwqsQI_";

2、编写Cookie字符串转map集合方法

 public static Map<String,String> cookieToMap(String value) {
        Map<String, String> map = new HashMap<String, String>();
        if (value.contains(";")) {
            String values[] = value.split(";");
            for (String val : values) {
                String vals[] = val.split("=");
                map.put(vals[0], vals[1]);
            }
        } else {
            String values[] = value.split("=");
            map.put(values[0], values[1]);
        }
        return map;
    }

3、验证结果是否符合预期结果

{traceid=ca4c9c8b50,  _qpsvr_localtk=0.2810983015733952,  uin=o0327844761,  _gid=GA1.2.85700497.1617513691,  ptcz=f997dfbd9d785b321bb377710933cae37308f34abb4b2340706eda53e23455cc,  _gat_gtag_UA_172919674_1=1,  p_skey=6dlS-INlRzNbnEOA09*Zn2l6cfPMI4ardDbcWCwqsQI_,  skey=@APPCpl4ip,  pt4_token=EWPb3WyZfLoQPIfmYfSjWDKOJXOIt09*xjIidJVdC54_,  pgv_info=ssid,  _ga=GA1.2.704388932.1617513691,  qqmusic_uin=0327844761,  RK=uCLoGvbeXG,  p_uin=o0327844761,  qqmusic_fromtag=6,  qqmusic_key=@R3lRxCHCr,  ptui_loginuin=327844761,  pgv_pvid=4861902100}
