麻烦大神帮忙看看，http://club.dearedu.com/member/index.php是一个教育网站，我用cookie登录网站之后获取了下载链接，但是下载不了文件

print(url1)

sys.argv = ['you-get', '-o', toPath, url1]

except:

pass

此代码目前存在的问题：登陆成功但是不能下载

你下载的request中有没有带上对应的cookie等信息，不然服务器还是可能认为你没有认证

cookie不能直接用字符串，解析处理一下

from http.cookies import SimpleCookie

rawdata = 'Cookie: devicePixelRatio=1; ident=exists; __utma=13103r6942.2918; __utmc=13103656942; __utmz=13105942.1.1.1.utmcsr=google|utmccn=(organic)|utmcmd=organic|utmctr=(not%20provided); mp_3cb27825a6612988r46d00tinct_id%22%3A%201752338%2C%22%24initial_referrer%22%3A%20%22https%3A%2F%2Fwww.pion_created_at%22%3A%20%222015-08-03%22%2C%22platform%22%3A%20%22web%22%2C%%22%3A%20%%22%7D; t_session=BAh7DUkiD3Nlc3NpbWVfZV9uYW1lBjsARkkiH1BhY2lmaWMgVGltZSAoVVMgJiBDYW5hZGEpBjsAVEkiFXNpZ25pbl9wZXJzb25faWQGOwBGaQMSvRpJIhRsYXN0X2xvZ2luX2RhdGUGOwBGVTogQWN0aXZlU3VwcG9ydDo6VGltZVdpdGhab25lWwhJdToJVGltZQ2T3RzAAABA7QY6CXpvbmVJIghVVEMGOwBUSSIfUGFjaWZpZWRfZGFzaGJvYXJkX21lc3NhZ2UGOwBGVA%3D%3D--6ce6ef4bd6bc1a469164b6740e7571c754b31cca'
cookie = SimpleCookie()
cookie.load(rawdata)

# Even though SimpleCookie is dictionary-like, it internally uses a Morsel object
