C#實現微信公眾號群發消息(解決一天只能發一次的限制)

編輯:C#入門知識

總體思路:1.首先必須要在微信公眾平台上申請一個公眾號。

    2.然後進行模擬登陸。(由於我對http傳輸原理和編程不是特別懂,在模擬登陸的地方,不是特別清楚,希望有大神指教)

                   3.模擬登陸後會獲得一個token(令牌)和cookie。

                   4.因為模擬登陸後相當於就進入了微信公眾平台,在這個裡面就可以抓取到需要的數據,如公眾好友的昵稱,fakeId。其中的fakeid非常重要,因為傳輸數據必須要知道                      對方的fakeid。

                   5.知道對方的fakeid就可以進行數據的發送了。

                          我整個項目的代碼在下載裡面有

               不過裡面還有一些小問題,希望有人繼續修改和討論!也有人說這樣會被封號,所以請謹慎操作

講一下我項目裡面的主要內容

1.WeiXinLogin.cs類是用來執行登陸功能的
 //對密碼進行MD5加密


 static string GetMd5Str32(string str)
    {
        MD5CryptoServiceProvider md5Hasher = new MD5CryptoServiceProvider();
        // Convert the input string to a byte array and compute the hash. 
        char[] temp = str.ToCharArray();
        byte[] buf = new byte[temp.Length];
        for (int i = 0; i < temp.Length; i++)
        {
            buf[i] = (byte)temp[i];
        }
        byte[] data = md5Hasher.ComputeHash(buf);
        // Create a new Stringbuilder to collect the bytes 
        // and create a string. 
        StringBuilder sBuilder = new StringBuilder();
        // Loop through each byte of the hashed data  
        // and format each one as a hexadecimal string. 
        for (int i = 0; i < data.Length; i++)
        {
            sBuilder.Append(data[i].ToString("x2"));
        }
        // Return the hexadecimal string. 
        return sBuilder.ToString();
    }

//執行登陸操作
    public static bool ExecLogin(string name,string pass)
    {
        bool result = false;
        string password = GetMd5Str32(pass).ToUpper();
        string padata = "username=" + name + "&pwd=" + password + "&imgcode=&f=json";
        string url = "http://mp.weixin.qq.com/cgi-bin/login?lang=zh_CN ";//請求登錄的URL
        try
        {
            CookieContainer cc = new CookieContainer();//接收緩存
            byte[] byteArray = Encoding.UTF8.GetBytes(padata); // 轉化
            HttpWebRequest webRequest2 = (HttpWebRequest)WebRequest.Create(url);  //新建一個WebRequest對象用來請求或者響應url
            webRequest2.CookieContainer = cc;                                      //保存cookie 
            webRequest2.Method = "POST";                                          //請求方式是POST
            webRequest2.ContentType = "application/x-www-form-urlencoded";       //請求的內容格式為application/x-www-form-urlencoded
            webRequest2.ContentLength = byteArray.Length;
            Stream newStream = webRequest2.GetRequestStream();           //返回用於將數據寫入 Internet 資源的 Stream。
            // Send the data.
            newStream.Write(byteArray, 0, byteArray.Length);    //寫入參數
            newStream.Close();
            HttpWebResponse response2 = (HttpWebResponse)webRequest2.GetResponse();
            StreamReader sr2 = new StreamReader(response2.GetResponseStream(), Encoding.Default);
            string text2 = sr2.ReadToEnd();


            //此處用到了newtonsoft來序列化
            WeiXinRetInfo retinfo = Newtonsoft.Json.JsonConvert.DeserializeObject<WeiXinRetInfo>(text2);
            string token = string.Empty;
            if (retinfo.ErrMsg.Length > 0)
            {
                token = retinfo.ErrMsg.Split(new char[] { '&' })[2].Split(new char[] { '=' })[1].ToString();//取得令牌
                LoginInfo.LoginCookie = cc;
                LoginInfo.CreateDate = DateTime.Now;
                LoginInfo.Token = token;
                result = true;
            }
        }
        catch (Exception ex)
        {
         
            throw new Exception(ex.StackTrace);
        }
        return result;
    }


    public static class LoginInfo
    {
        /// <summary>
        /// 登錄後得到的令牌
        /// </summary>       
        public static string Token { get; set; }
        /// <summary>
        /// 登錄後得到的cookie
        /// </summary>
        public static CookieContainer LoginCookie { get; set; }
        /// <summary>
        /// 創建時間
        /// </summary>
        public static DateTime CreateDate { get; set; }


    }

 

 

2.在WeiXin.cs類中實現發送數據
 public static bool SendMessage(string Message, string fakeid)
    {
        bool result = false;
        CookieContainer cookie = null;
        string token = null;
        cookie = WeiXinLogin.LoginInfo.LoginCookie;//取得cookie
        token =  WeiXinLogin.LoginInfo.Token;//取得token


        string strMsg = System.Web.HttpUtility.UrlEncode(Message);  //對傳遞過來的信息進行url編碼
        string padate = "type=1&content=" + strMsg + "&error=false&tofakeid=" + fakeid + "&token=" + token + "&ajax=1";
        string url = "https://mp.weixin.qq.com/cgi-bin/singlesend?t=ajax-response&lang=zh_CN";


        byte[] byteArray = Encoding.UTF8.GetBytes(padate); // 轉化


        HttpWebRequest webRequest2 = (HttpWebRequest)WebRequest.Create(url);


        webRequest2.CookieContainer = cookie; //登錄時得到的緩存


        webRequest2.Referer = "https://mp.weixin.qq.com/cgi-bin/singlemsgpage?token=" + token + "&fromfakeid=" + fakeid + "&msgid=&source=&count=20&t=wxm-singlechat&lang=zh_CN";


        webRequest2.Method = "POST";


        webRequest2.UserAgent = "Mozilla/5.0 (Windows NT 5.1; rv:2.0.1) Gecko/20100101 Firefox/4.0.1";


        webRequest2.ContentType = "application/x-www-form-urlencoded";


        webRequest2.ContentLength = byteArray.Length;


        Stream newStream = webRequest2.GetRequestStream();


        // Send the data.           
        newStream.Write(byteArray, 0, byteArray.Length);    //寫入參數   


        newStream.Close();


        HttpWebResponse response2 = (HttpWebResponse)webRequest2.GetResponse();


        StreamReader sr2 = new StreamReader(response2.GetResponseStream(), Encoding.Default);


        string text2 = sr2.ReadToEnd();
        if (text2.Contains("ok"))
        {
            result = true;
        }
        return result;
    }

 

 

 

 

3.SendMessage.aspx.cs中主要實現獲取fakeid
 public static ArrayList SubscribeMP()
    {
      
        try
        {
            CookieContainer cookie = null;
            string token = null;


          
            cookie = WeiXinLogin.LoginInfo.LoginCookie;//取得cookie
            token = WeiXinLogin.LoginInfo.Token;//取得token


            /*獲取用戶信息的url,這裡有幾個參數給大家講一下,1.token此參數為上面的token 2.pagesize此參數為每一頁顯示的記錄條數


            3.pageid為當前的頁數,4.groupid為微信公眾平台的用戶分組的組id,當然這也是我的猜想不一定正確*/
            string Url = "https://mp.weixin.qq.com/cgi-bin/contactmanagepage?t=wxm-friend&token=" + token + "&lang=zh_CN&pagesize=10&pageidx=0&type=0&groupid=0";
            HttpWebRequest webRequest2 = (HttpWebRequest)WebRequest.Create(Url);
            webRequest2.CookieContainer = cookie;
            webRequest2.ContentType = "text/html; charset=UTF-8";
            webRequest2.Method = "GET";
            webRequest2.UserAgent = "Mozilla/5.0 (Windows NT 5.1; rv:2.0.1) Gecko/20100101 Firefox/4.0.1";
            webRequest2.ContentType = "application/x-www-form-urlencoded";
            HttpWebResponse response2 = (HttpWebResponse)webRequest2.GetResponse();

 


            StreamReader sr2 = new StreamReader(response2.GetResponseStream(), Encoding.Default);
            string text2 = sr2.ReadToEnd();
            MatchCollection mc;


            //由於此方法獲取過來的信息是一個html網頁所以此處使用了正則表達式,注意:(此正則表達式只是獲取了fakeid的信息如果想獲得一些其他的信息修改此處的正則表達式就可以了。)
             Regex r = new Regex("\"fakeId\"\\s\\:\\s\"\\d+\""); //定義一個Regex對象實例
            mc = r.Matches(text2);
            Int32 friendSum = mc.Count;          //好友總數


            string fackID ="";


            ArrayList fackID1 = new ArrayList();


            for (int i = 0; i < friendSum; i++)
            {
                fackID = mc[i].Value.Split(new char[] { ':' })[1];
                fackID = fackID.Replace("\"", "").Trim();
                fackID1.Add(fackID);
            }


            return fackID1;
   }
        catch (Exception ex)
        {
            throw new Exception(ex.StackTrace);
        }
    }
