java.lang.IllegalArgumentException: An invalid character [32] was present in the Cookie value

今天在练习 cookie时意外的报了这个错。

java.lang.IllegalArgumentException: An invalid character [32] was present in the Cookie value
1
这句话的意思是
一个不识别的字符[32]出现在了cookie当中

我的代码：是在cookie中添加了时间，而时间的格式化中我是用了format。上代码：

光标所在之处，这里的天和小时之间用的是空格分隔，所以会报错。

只要将这个空格修改掉就可以了。比如改成 -
问题解决
