from http import cookiejar

實例化CookieJar（） 通過實例化的對象 保存cookie

cookie_object = cookiejar.CookieJar()

根據創建的cookie生成cookie的管理器

handler = request.HTTPCookieProcessor(cookie_object)

urlopen()函數不支持驗證、cookie或者其它HTTP高級功能。要支持這些功能，必須使用build_opener()函數創建自定義Opener對象。

opener = request.build_opener(handler)

##### def store(cookie):
#####   cookie_object.append(cookie)

##### def check_response(response):
#####   if 'cookie' in response:
#####       handler.store(response['cookie'])

##### url

url = 'http://www.renren.com/ajaxLogin/login?1=1&uniqueTimestamp=2018721441132'

form = {
    'email': '18510556963',
    'icode': '',
    'origURL': 'http://www.renren.com/home',
    'domain': 'renren.com',
    'key_id': '1',
    'captcha_type': 'web_login',
    'password': '95cb2a1d59b918e0d16ab5d3535fb40103e4b546e651a3e3c99b91876927c78a',
    'rkey': 'a7bccfbafd7ee702247450942dff5611',
    'f': 'http%3A%2F%2Fwww.renren.com%2F966927992',
}

post

form_bytes = parse.urlencode(form).encode('utf-8')

##### response = request.urlopen(url, form_bytes)
##### opener = request.build_opener()
##### opener.open()

response = opener.open(url, form_bytes)
html_bytes = response.read()

#####html_bytes = post(url, form=form)

打印結果

##### print(html_bytes)

通過json獲取一個字典類型

res_dict = json.loads(html_bytes.decode('utf-8'))
home_url = res_dict['homeUrl']

訪問頁面

response = opener.open(home_url)
html_bytes = response.read()
print(html_bytes.decode('utf-8'))
