python cookie 保存到文件里，以及从文件中读取cookie

data = bytes(urllib.parse.urlencode(loginData), encoding='utf8')
# cookieJar = http.cookiejar.CookieJar()
cookieJar = http.cookiejar.MozillaCookieJar('cookie.txt')
handler = urllib.request.HTTPCookieProcessor(cookieJar)
opener = urllib.request.build_opener(handler)
urllib.request.install_opener(opener)
data = urllib.request.urlopen(loginURL, data)
print(data.read())

for item in cookieJar:
    print(item.name + "=" + item.value)
cookieJar.save(ignore_discard=True, ignore_expires=True)

cookie = http.cookiejar.MozillaCookieJar()
cookie.load('cookie.txt', ignore_discard=True, ignore_expires=True)
hander = urllib.request.HTTPCookieProcessor(cookie)
opener = urllib.request.build_opener(hander)
requestData = {"type":1,
              "timestamp":0,
               "versionNumber":"9.4.0",
               "platform":2,
               "channel":"AppStore",
               "phoneVersion":"11.3",
                "phoneModel":"iPhone%208",
               "phoneBrand":"Apple"}
byteData = bytes(urllib.parse.urlencode(requestData), encoding='utf8')
urllib.request.install_opener(opener)
data = urllib.request.urlopen(ListURL, byteData)
print(data.read())

用MozillaCookieJar代替之前的CookieJar，传入文件名就可以保存了，下面的用load来载入之前的cookie
