如何以编程方式登录网站 [英] How to Programmatically Log in to a Website

问题描述

我不知道如何以编程方式登录此网站 我搜索了stackoverflow，发现了此，但我仍然不知道不知道在URL或URI中放入什么.

I dont know how to programmatically login to this site I've searched through stackoverflow and found this, but I still don't know what to put into URL or URI.

推荐答案

当我只输入用户名'abc'和密码'def'并单击按钮时，我将获得以下发布数据:

When I just type in username 'abc' and password 'def' and hit the button I get the following post data:

next = apps％2Flinks％2F& why = pw& email = abc& password = def& fw_human =

next=apps%2Flinks%2F&why=pw&email=abc&password=def&fw_human=

因此，如果您仅使用该帖子数据并将其替换为适当的信息，就可以使我相信，您可以模拟手动登录.

So that leads me to beleive if you just use that post data and replace it with the appropriate information, you can simulate a manual login.

因此，从您链接的堆栈溢出中，将采用以下形式:

So from the stack overflow you linked, this would take the form:

string formUrl = "http://ratings-plus.webs.com/apps/auth/doLogin"; // NOTE: This is the URL the form POSTs to, not the URL of the form (you can find this in the "action" attribute of the HTML's form tag
string formParams = string.Format("next=apps%2Flinks%2F&why=pw&email={0}&password={1}&fw_human=", "your email", "your password");
string cookieHeader;
WebRequest req = WebRequest.Create(formUrl);
req.ContentType = "application/x-www-form-urlencoded";
req.Method = "POST";
byte[] bytes = Encoding.ASCII.GetBytes(formParams);
req.ContentLength = bytes.Length;
using (Stream os = req.GetRequestStream())
{
    os.Write(bytes, 0, bytes.Length);
}
WebResponse resp = req.GetResponse();
cookieHeader = resp.Headers["Set-cookie"];

请注意，在将来的请求中，您将需要使用返回的任何cookie值来保持您的身份验证状态.

Note that in future requests you will need to then use whatever the cookie value that is returned to maintain your authenticated status.
