自动从密码保护的网站上下载 [英] Automate downloads from password protected website

问题描述

我需要一些帮助，我被分配一个工作项目。目前，我们手工去的网站，登录，然后从供应商的网站每月下载2 Excel文件。然后将文件加载到SQL。

I need some help with a work project I have been assigned. At the moment we manually go to the site, logon and then download 2 excel files from a supplier's website every month. The files are then loaded into SQL.

我们希望这个过程自动化。现在文件装载到SQL我可以做，但我不知道我怎么可以自动登录到网站上输入我的用户信息和收集的文件。我主要是处理SQL和有很少的.NET体验，因此任何代码示例将最赞赏。

We want to automate this process. Now the loading of the files into SQL I can do, but I am not sure how I can automate logging onto the website entering my user details and collecting the files. I mostly deal with SQL and have very little .NET experience, so any code samples would be most appreciated.

只是为了确认。注册表是一个aspx页面上。只是一个基本的形式包含用户名和安培表;密码字段，忘记密码的链接和登录按钮

Just to confirm. The logon form is on a aspx page. just a basic form with a table containing the username & password fields, the forgotten password link and the logon button

推荐答案

您可以使用Web客户端或HttpWebRequest的。

You can either use webclient or httpwebrequest.

HttpWebRequest的例子：

    HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create("http://sso.bhmobile.ba/sso/login"); 
    req.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.0.3705;)"; 
    req.Method = "POST";
    req.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8";
    req.Headers.Add("Accept-Language: en-us,en;q=0.5");
    req.Headers.Add("Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7");
    req.KeepAlive = true;
    req.Headers.Add("Keep-Alive: 300");
    req.Referer ="http://sso.bhmobile.ba/sso/login";

    req.ContentType = "application/x-www-form-urlencoded"; 

    String Username = "username";
    String PassWord = "Password";

    StreamWriter sw = new StreamWriter(req.GetRequestStream());
    sw.Write("application=portal&url=http%3A%2F%2Fwww.bhmobile.ba%2Fportal%2Fredirect%3Bjsessionid%3D1C568AAA1FB8B5C757CF5F68BE6ECE65%3Ftype%3Dssologin%26url%3D%2Fportal%2Fshow%3Bjsessionid%3D1C568AAA1FB8B5C757CF5F68BE6ECE65%3Fidc%3D1023278&realm=sso&userid=" + Username + "&password=" + password + "&x=16&y=11");
    sw.Close();

    HttpWebResponse response = (HttpWebResponse)req.GetResponse();


    StreamReader reader = new StreamReader(response.GetResponseStream());
    string tmp = reader.ReadToEnd();

    foreach (Cookie cook in response.Cookies)
    {
        tmp += "\n" + cook.Name + ": " + cook.Value;
    }


    Response.Write(tmp);
    Response.End();

Web客户端例如：

WebClient wc = new WebClient();
wc.Credentials = new NetworkCredential("username", "password");
string url = "http://foo.com";                  
try
{
        using (Stream stream = wc.OpenRead(new Uri(url)))
        {
                using (StreamReader reader = new StreamReader(stream))
            {
                return reader.ReadToEnd();
             }
        }
}
catch (WebException e)
{
        //Error handeling
}
