私信给我一个用户名密码，帮你写。

这是成功登录，并且获取到了用户的注册时间等信息。说明登录成功了。

我想请问一下 caozhy ，你作为版主怎么可以随便删除别人的恢复，如果涉嫌 复制、灌水或者广告，那情有可原，如果不是，那为何随便删除，是否是触及了你的利益，因为如果是回答有误，你可以指正，也没必要删除，我想请你给个解释，为防止再被随意删除，截图为证

在C#中，可以使用HttpWebRequest进行相关的模拟登陆，登陆后进行相关的操作，比如抓取数据，页面分析，制作相关登陆助手等等。

先说下流程

1.使用httpwebrequest先进入你要登录的网站，获取cookie

2.使用第一步获取的cookie到验证码的网页将验证码下载下来。

3.使用Post数据 发送至网站。如果有cookie则继续保存。

4.使用第三步的cookie登陆相关网页操作。

获取相关数据可以使用抓包工具进行抓取，如httpwatch。（网上下载的好多都有病毒，下载的时候注意点）

1。

///
/// 通过get方式请求页面，传递一个实例化的cookieContainer
///
///
///
///
public static ArrayList GetHtmlData(string postUrl, CookieContainer cookie)
{
HttpWebRequest request;
HttpWebResponse response;
ArrayList list = new ArrayList();
request = WebRequest.Create(postUrl) as HttpWebRequest;
request.Method = "GET";
request.UserAgent = "Mozilla/4.0";
request.CookieContainer = cookie;
request.KeepAlive = true;
request.CookieContainer = cookie;
try
{
//获取服务器返回的资源
using (response = (HttpWebResponse)request.GetResponse())
{
using (StreamReader reader =
new StreamReader(response.GetResponseStream(), Encoding.Default))
{
cookie.Add(response.Cookies);
//保存Cookies
list.Add(cookie);
list.Add(reader.ReadToEnd());
list.Add(Guid.NewGuid().ToString());//图片名
}
}
}
catch (WebException ex)
{
list.Clear();
list.Add("发生异常/n/r");
WebResponse wr = ex.Response;
using (Stream st = wr.GetResponseStream())
{
using (StreamReader sr =new StreamReader(st, System.Text.Encoding.Default))
{
list.Add(sr.ReadToEnd());
}
}
}
catch (Exception ex)
{
list.Clear();
list.Add("5");
list.Add("发生异常：" + ex.Message);
}
return list;
}

2.下载验证码，保存在本地。

view plaincopy to
clipboardprint?
///
/// 下载验证码图片并保存到本地
///
/// 验证码URL
/// Cookies值
/// 保存位置/文件名
public staticbool DowloadCheckImg(string Url, CookieContainer cookCon,string
savePath)
{
bool bol =
true;
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(Url);
//属性配置
webRequest.AllowWriteStreamBuffering = true;
webRequest.Credentials = System.Net.CredentialCache.DefaultCredentials;
webRequest.MaximumResponseHeadersLength = -1;
webRequest.Accept = "image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-shockwave-flash, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, /";
webRequest.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; Maxthon; .NET CLR 1.1.4322)";
webRequest.ContentType = "application/x-www-form-urlencoded";
webRequest.Method = "GET";
webRequest.Headers.Add("Accept-Language","zh-cn");
webRequest.Headers.Add("Accept-Encoding","gzip,deflate");
webRequest.KeepAlive = true;
webRequest.CookieContainer = cookCon;
try
{
//获取服务器返回的资源
using (HttpWebResponse webResponse = (HttpWebResponse)webRequest.GetResponse())
{
using (Stream sream = webResponse.GetResponseStream())
{
List list = new List();
while (true)
{
int data = sream.ReadByte();
if (data == -1)
break;
list.Add((byte)data);
}
File.WriteAllBytes(savePath, list.ToArray());
}
}
}
catch (WebException ex)
{
bol = false;
}
catch (Exception ex)
{
bol = false;
}
return bol;
}

3。发送post数据

view plaincopy to
clipboardprint?
///
/// 发送相关数据至页面
/// 进行登录操作
/// 并保存cookie
///
///
///
///
///
public static ArrayList PostData(string postData,string postUrl, CookieContainer
cookie)
{
ArrayList list = new ArrayList();
HttpWebRequest request;
HttpWebResponse response;
ASCIIEncoding encoding = new ASCIIEncoding();
request = WebRequest.Create(postUrl) as HttpWebRequest;
byte[] b = encoding.GetBytes(postData);
request.UserAgent = "Mozilla/4.0";
request.Method = "POST";
request.CookieContainer = cookie;
request.ContentLength = b.Length;
using (Stream stream = request.GetRequestStream())
{
stream.Write(b, 0, b.Length);
}
try
{
//获取服务器返回的资源
using (response = request.GetResponse()as HttpWebResponse)
{
using (StreamReader reader =
new StreamReader(response.GetResponseStream(), Encoding.UTF8))
{
if (response.Cookies.Count > 0)
cookie.Add(response.Cookies);
list.Add(cookie);
list.Add(reader.ReadToEnd());
}
}
}
catch (WebException wex)
{
WebResponse wr = wex.Response;
using (Stream st = wr.GetResponseStream())
{
using (StreamReader sr =
new StreamReader(st, System.Text.Encoding.Default))
{
list.Add(sr.ReadToEnd());
}
}
}
catch (Exception ex)
{
list.Add("发生异常/n/r"+ex.Message);
}
return list;
}

4。就是第三步请求的链接地址换一个就行了

好了

以上核心代码已经贴出了

具体实现需要靠你们按照你们自己的逻辑

你可以用前嗅的ForeSpider采集器帮你实现登录操作，直接在这个采集器里采集数据，比其他的方式都要简单一些，如果你不想用可视化采集，也是可以直接用代码语言编写的。
