过期时间为0的cookie，无法被携带在请求中，导致请求失败。

[zy-nesime]

我参考了发问题的要求，但我这个似乎不能按照那个格式来。这是我第一次着手参与到开源项目里，下面是关于cookie的问题和测试过程的详细描述。（我看有很多中文的提交，我就偷了写英文的懒）

问题

过期时间为0的cookie无法被携带在请求中。

我想添加对智慧树（一个学习网站）的支持，它所使用的cookie的过期时间为0，如果我们不手动更改导出cookie的过期时间，我们将无法请求到相关的资源。

但我认为不应该让用户去编辑cookie，所以我做了一些测试，试图解决它，但我遇到一些困难。我一方面不想更改cookie的信息（比如把过期时间设置成今后的某个时间），我觉得我们应该保持“我还在浏览器里”的那种状态，另一方面过期时间为0的cookie就算被生成，在发送请求的时候也不会被携带。

测试过程

我刚写好了智慧树的脚本，开始对脚本开始测试，发现请求uuid失败，也就是说有些cookie没有按预期加载，但我确实加载了cookie文件

./you-get https://studyh5.zhihuishu.com/videoStudy.html\#/studyVideo\?recruitAndCourseId\=4e505b5f45524258454a585858435d46 -l -c zhihuishu.com_cookies.txt  --debug

    raise KeyError('Can not request uuid Please check you cookies')
KeyError: 'Can not request uuid Please check you cookies'

然后找了找代码，发现在you-get的common模块中这段代码，把这样过期时间为0的cookie给过滤掉了

然后我把ignore_expires设为True，增加了一条日记的打印，继续测试，发现还是出现请求没有权限的问题，但这次cookie没有continue过去，所以应该是加载了。

后面我还是觉得是expiry的问题，于是我暴力的把所有cookie的过期时间都改成了未来的时间，再进行测试，发现按预期正确的请求和解析相关数据和地址了。

最后

因为这些cookie的实际可使用的时间就不长，加上cookie的特殊性质我不能一同附上来，所以如果需要配合复现问题，可以联系我，我将会积极配合。

提交的代码包括对智慧树网站的一些支持，以及修改了common里的代码，把所有的cookie的过期都设置在了未来（但我没有对其他网站进行测试，所有我不知道这样是否会导致一些别的问题）
