Question

我是网络抓取的新手。我正在尝试使用以下代码登录网站：

urlLogin = 'https://b*********.****n.dk/Authorization/LogOn'
urlData = 'https://b*********.****n.dk//Search/Index'
payload = {
'UserName':'{{username}}',
'Password':'{{a_password}}'
}

with requests.Session() as s:
    s.post(urlLogin, data=payload)
    r = s.get(urlData)

我收到以下错误：

    Traceback (most recent call last):
  File "C:\Python34\lib\site-packages\requests\packages\urllib3\connectionpool.py", line 372, in _make_request
    httplib_response = conn.getresponse(buffering=True)

可能是什么原因？许多教程都提出了这样做的方法，似乎它在我的案例中并不起作用。

使用此代码：

with requests.Session() as s:
p = s.post(urlLogin, data=payload)
print(p.text)

输出是：

[ArgumentException]: The parameters dictionary contains a null entry for parameter &#39;remmemberMe&#39; of non-nullable type &#39;System.Boolean&#39; for method &#39;System.Web.Mvc.ActionResult LogOn(System.String, System.String, Boolean)&#39; in &#39;SalesOptimizer.Controllers.AuthorizationController&#39;. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter.
Parameter name: parameters

这意味着我不得不再向负载添加一个变量。代码变为：

 payload = {
            'username':"a_username",
            'password':"a_password",
            'remmemberMe': True
            }

 with requests.Session() as s:
            p = s.post(urlLogin, data=payload)

这就是答案。（新问题是输出提供密码不正确的文本。密码是否包含这些字符* >？我可以使用此用户名通过网络登录密码。）
