前两篇已把相应的准备工作和功能说明列了一下，今天就把详细的实现写一下,以后的将把13800138000的语音拨号系统，和手机短信群发的的实现也发上。
开始这次的内容。
首先就是需要用到模拟提交的两个类
HttpHead.cs 这个类（其实是结构）它的主要功能就是封装了Http请求的一个头信息
using System;
using System.Net;
using System.Drawing;
namespace NetHelper {
/// <summary>
/// Http头信息设置
/// </summary>
public struct HttpHead {
public String Host; //主机
public String Referer; //引用
public CookieCollection Cookies; //cookies容器
public String PostData; //请求的传给服务器的参数
public String Method; //请求方式常见的POST,GET
public String ContentType;
public String Html; //响应的html代码
public String AbsoluteUri;
public Bitmap Image; //如果请求的是图片，这里返回一个Bitmap对象
public Boolean IsImage; //是否为图片
}
}
HttpRequest.cs //用来发起提交的
namespace NetHelper {
using System;
using System.Drawing;
using System.IO;
using System.Net;
using System.Text;
/// <summary>
/// Http请求封装类，包括 POST,GET请求
/// 幸福海
/// </summary>
public class HttpRequest {
private CookieContainer cookies;
public CookieContainer Cookies {
get { return this.cookies; }
set { this.cookies = value; }
}
/// <summary>
/// Http请求
/// 幸福海
/// </summary>
public HttpRequest() {
this.Cookies = new CookieContainer();
}
/// <summary>
/// 发送HTTP请求
/// </summary>
/// <param name="Head">HTTP头结构</param>
/// <returns></returns>
public String Send(ref HttpHead Head) {
HttpWebResponse Response = null;
String val = "";
try {
HttpWebRequest Request = (HttpWebRequest)HttpWebRequest.Create(Head.Host);
Request.ProtocolVersion = new Version("1.1");
Request.Referer = Head.Referer;
Request.Accept = "*/*";
Request.CookieContainer = this.Cookies;
Request.Timeout = 100000;
Request.Headers.Add("Accept-Language", "zh-CN");
Request.KeepAlive = true;
Request.UserAgent = "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1;.NET CLR 2.0.50727)";
if (Head.Method.ToLower() == "post") {
Request.Method = "POST";
if (String.IsNullOrEmpty(Head.ContentType)) {
Request.ContentType = "application/x-www-form-urlencoded";
}
else {
Request.ContentType = Head.ContentType;
}
if (Head.PostData != null && Head.PostData.Length > 0) {
Byte[] byteData = Encoding.Default.GetBytes(Head.PostData);
Request.ContentLength = byteData.Length;
Stream WriteStream = Request.GetRequestStream();
WriteStream.Write(byteData, 0, byteData.Length);
WriteStream.Close();
}
}
try {
Response = (HttpWebResponse)Request.GetResponse();
}
catch (WebException ex) {
if (ex.Response != null) {
Response = (HttpWebResponse)ex.Response;
}
else {
return "网络异常";
}
}
foreach (Cookie cookie in Request.CookieContainer.GetCookies(Request.RequestUri)) {
this.Cookies.Add(cookie);
}
Stream dataStream = Response.GetResponseStream();
if (Head.IsImage) {
Bitmap img = new Bitmap(dataStream);
Head.Image = img;
return "";
}
else {
String encode = Response.CharacterSet;
if (encode == null) encode = "gb2312";
if (encode.ToLower() == "iso-8859-1") encode = "gb2312";
StreamReader reader = new StreamReader(dataStream, Encoding.GetEncoding(encode));
val = reader.ReadToEnd();
Head.AbsoluteUri = Response.ResponseUri.AbsoluteUri;
reader.Close();
dataStream.Close();
Response.Close();
Head.Html = val;
}
}
catch {
return "未知错误";
}
return val;
}
}
}
这个类中最关键的是那个关联cookie,这里不详细说明，具体看代码，如果有不明白的地方，请提出来。
//开始提交联通卡密，这就是那个按钮对应的事件
private void BtnOk_Click(object sender, EventArgs e) {
String strTel = tbTel.Text.Trim();
String strPass = tbPass.Text.Trim();
String Result = UnionCardPay(strTel, strPass);
lblMsg.Text = BuilderErrMsg(Result); //显示充值信息
}
//重填输入框，重置按钮事件
private void BtnReset_Click(object sender, EventArgs e) {
tbTel.Text = tbPass.Text = String.Empty;
}
//字符串中获取指定开始和结束的子串
private String GetValue(string str, string s, string e) {
Regex regex = new Regex("(?<=(" + s + "))[.\\s\\S]*?(?=(" + e + "))", RegexOptions.Multiline | RegexOptions.Singleline);
return regex.Match(str).Value;
}
//对错误编码进行处理
private String BuilderErrMsg(String errCode) {
String val = "";
switch (errCode) {
case "001": val = "充值卡已使用"; break;
case "002": val = "您输入的充值卡密码有误"; break;
case "003": val = "您输入的交费充值号码不存在"; break;
case "004": val = "请正确输入手机号码"; break;
case "005": val = "验证码5次匹配不成功"; break;
case "006": val = "充值卡已过期"; break;
case "007": val = "充值失败"; break;
case "008": val = "异常,或无法连接服务器"; break;
case "888": val = "充值成功"; break;
}
return val;
}
//联通卡密提交
String UnionCardPay(String tel, String pass) {
try {
String result = "";
NetHelper.HttpHead head = new NetHelper.HttpHead();
NetHelper.HttpRequest request = new NetHelper.HttpRequest();
request.Cookies = new System.Net.CookieContainer();
//充值初始化页
head.Host = "http://upay.10010.com/web/Recharge/rechargeInit";
head.Method = "GET";
request.Send(ref head);
result = head.Html;
String state = GetValue(result, "name=\"secstate.state\" value=\"", "\" id=\"secstate.state\"/>");
//自动过验证码
Int16 index = 1;
while (1 == 1) {
head.Host = "http://upay.10010.com/web/EsfWeb/VerifyCode.action?timestamp=" + DateTime.Now.ToString("yyyyMMddhhmmss");
head.IsImage = true;
head.Method = "GET";
request.Send(ref head);
Bitmap img = head.Image;
CheckImage imgChk = new CheckImage();
String chk = imgChk.GetCheckCode(img);
//提交充值号码和卡密
String para = "numbean.userNumBean.userSelNum=1&numbean.userNumBean.otherNum=" + tel + "&cardPwd=" + pass + "&verifyCode=" + chk;
para += "&numbean.cityCodeBean.provinceId=&numbean.cityCodeBean.cityId=&numbean.cityCodeBean.cityCode=&numbean.userNumBean.telNum=";
para += "&secstate.state=" + state;
head.Host = "http://upay.10010.com/web/Recharge/rechargeConfirm";
head.PostData = para;
head.IsImage = false;
head.Method = "POST";
head.Referer = "http://upay.10010.com/web/Recharge/rechargeInit";
request.Send(ref head);
result = head.Html;
state = GetValue(result, "name=\"secstate.state\" value=\"", "\" id=\"secstate.state\"/>");
result = GetValue(result, "<div id='ecs_err_msg_div' class='ceng_jinshi' cssStyle='' align='left'>", "</div>");//提交状态
//状态处理
if (result.Contains("验证码不正确")) { // 验证码匹配5次不正确。
if (index++ >= 5) {
return "005";
}
else {
continue; //重新跳转到验证码识别
}
}
break;
}
if (result.Contains("输入的充值卡已充值")) { //尊敬的用户您好，您输入的充值卡已充值，无法再次使用，请更换充值卡重新操作
return "001";
}
if (result.Contains("您输入的充值卡密码有误")) { //尊敬的用户您好，您输入的充值卡密码有误，请重新输入。
return "002";
}
if (result.Contains("您输入的交费充值号码不存在")) { // 尊敬的用户您好，您输入的交费充值号码不存在，请重新输入。
return "003";
}
if (result.Contains("请正确输入手机号码")) { //请正确输入手机号码。
return "004";
}
if (result.Contains("过期")) { //充值卡已过期。
return "006";
}
//确认充值结果
head.Host = "http://upay.10010.com/web/Recharge/rechargeResult";
head.Method = "POST";
head.PostData = "secstate.state=" + state;
head.Cookies = request.Cookies.GetCookies(new Uri(head.Host));
head.Referer = "http://upay.10010.com/web/Recharge/rechargeConfirm";
request.Send(ref head);
result = head.Html;
if (!result.Contains("<td>成功</td>")) { //最后一步没有完成，即充值失败
return "009";
}
return "888";
}
catch {
return "009";
}
}
全部代码就这些，这里主要是给大家整理思路，主要是通过C#向服务器提交数据
现把联通卡密提交的顺序说一下
1，当我们启动抓包工具，开始提交数据的时候，我们会看到，有几个参数提到了服务器端
这几个，名称看上去怪怪的，原因很简单，主是因为联通这个站是JAVA来写到了，用了Bean,所有看上去名称就比较上
其实对我们来说无所谓
numbean.userNumBean.userSelNum 如果是给手机充值这个是1，固话小灵通，宽带就为2
numbean.userNumBean.otherNum 手机号码
cardPwd 卡密
verifyCode 验证码，
下面四个我们可以不管他了
numbean.cityCodeBean.provinceId
numbean.cityCodeBean.cityId
numbean.cityCodeBean.cityCode
numbean.userNumBean.telNum
这个参数非常重要，也就是一个隐藏域的东西，估计是一个加密字符串充,如果错了，就提交不上了。
secstate.state
最后当我们点提交的时候，就可以得到相应的信息,假如你还要获取订单号，和充值的金额，你只对html源进行分析，截取就行了
OK,这个联通的卡密就写到这里，由于第一次写东西，没有什么思路，呵呵，想到哪就写到哪了，毕竟文学功底有限，希望以后写文章这方面的功能加强些，
如果大家对这个联通卡密自动提交还不是很清楚的话，可以随你给我发信息.
