Authentication 以编程方式登录到网页HTTPS(C#)
我正试图以编程方式登录到一个网页,我感到非常高兴。我看了看fiddler,看看浏览器在做什么,但我正在努力用代码复制它。 这是到目前为止的代码Authentication 以编程方式登录到网页HTTPS(C#),authentication,https,httpwebrequest,Authentication,Https,Httpwebrequest,我正试图以编程方式登录到一个网页,我感到非常高兴。我看了看fiddler,看看浏览器在做什么,但我正在努力用代码复制它。 这是到目前为止的代码 private void VisitUrl() { string pageVisited = string.Empty; CookieContainer cookies = new CookieContainer(); //Go to login page so that we get a cookie HttpWebR

我遇到的问题是,当我尝试第三个请求时,它只是缺少了一个cookie,似乎让我回到了登录页面。这是使用fiddler的浏览器成功登录:

请求15是一个重定向,这个请求已经有丢失的cookie,但是我不知道这个cookie是如何创建的。在我的第二个请求的响应中,它似乎不存在,我在调试时查看过
我需要请求所有的GIF吗?您是否尝试过使用
doLogin.AllowAutoRedirect = true;
HTTP状态代码302(第15行)显示文件已“临时移动”。您可能需要允许重定向
此外,cookie信息也可以在标题
集合属性中传递。在响应的Headers.Keys
集合中查找任何名称,如“cookie”。例如,我必须登录的网站使用名称“Set Cookie”。我得到的值如下:
if (response.Headers["Set-Cookie"] != null)
{
Match match = Regex.Match(response.Headers["Set-Cookie"].ToString(), @"(?'Name'\w+)
=(?'Value'\w+).+=(?'Path'[\s\S]+)");
if (match.Success)
{
Cookie cookie = new Cookie(match.Groups["Name"].ToString(),
match.Groups["Value"].ToString(), match.Groups["Path"].ToString(), "domain.name.com");
cookies.Add(cookie);
}
}
你试过使用吗
doLogin.AllowAutoRedirect = true;

if (match.Success)
{
Cookie cookie = new Cookie(match.Groups["Name"].ToString(),
match.Groups["Value"].ToString(), match.Groups["Path"].ToString(), "domain.name.com");
cookies.Add(cookie);
}
}
不过,我相当肯定,我尝试过将allowautoredirect设置为true,但没有任何效果。等我有时间的时候,我可能会再试试。302状态码可能与此无关,但您是否检查了HTTP headers集合中的cookie信息?不过,我相当肯定我尝试过将allowautoredirect设置为true,但没有任何效果。等我有时间的时候,我可能会再来一次。302状态码可能与此无关,但您是否检查了HTTP headers集合中的cookie信息?标题有点误导。如果端口80未打开,则程序无效。互动程序应该是“通过HTTP(c#)以编程方式登录到HTTPS网页”,标题有点误导。如果端口80未打开,则程序无效。互动程序应该是“通过HTTP(c#)以编程方式登录到HTTPS网页”
