Question

我正在尝试登录网站＆＃34; https://my.freecycle.org/＆＃34; 我尝试过各种方法，包括这个stackoverflow Login to website, via C# 但没有运气，它似乎不是标准形式。

<form method="post" class="cols_2" action="https://my.freecycle.org/login" id="loginform" accept-charset="utf-8"><fieldset>
<input type="hidden" name="referer" value="">

<label for="username">Username (or email address):</label>
<input type="text" name="username" id="username"><br>

<label for="pass">Password:</label>
<input type="password" name="pass" id="pass"><br>

<input type="submit" value="Log in" class="button defaultButton vgap ui-button ui-widget ui-state-default ui-corner-all" role="button" aria-disabled="false">

我真的很感激一些帮助，下面是我试过的代码。

private void button1_Click(object sender, EventArgs e)
    {
        CookieAwareWebClient client = new CookieAwareWebClient();
        client.BaseAddress = @"https://my.freecycle.org/";
        NameValueCollection loginData = new NameValueCollection();
        loginData.Add("username", @"myemail@gmail.com");
        loginData.Add("pass", "mypassword");
        client.UploadValues("login", "POST", loginData);

        //Now you are logged in and can request pages    
        string htmlSource = client.DownloadString(client.BaseAddress);
        textBox1.Text = htmlSource;
    }

public class CookieAwareWebClient : WebClient
{
    private CookieContainer cookie = new CookieContainer();

    protected override WebRequest GetWebRequest(Uri address)
    {
        WebRequest request = base.GetWebRequest(address);
        if (request is HttpWebRequest)
        {
            (request as HttpWebRequest).CookieContainer = cookie;
        }
        return request;
    }
}

对不起，如果我浪费了所有人的时间来研究这个问题。在想到为什么没有错误之后，在考虑上述评论问题时，我意识到这一行。

string htmlSource = client.DownloadString(client.BaseAddress);

从初始登录页面获取源，而不是登录后我想要的源页面。

当我输入正确的登陆网址时，我得到了我期望的结果。

string htmlSource = client.DownloadString(@"https://my.freecycle.org/page/i/need");
