微信公众号开发基本配置

微信公众号开发基本配置
先进入微信公众平台进行公众号申请,也可以用测试号,测试号地址为:http://mp.weixin.qq.com/debug/cgi-bin/sandbox?t=sandbox/login。

在接口配置信息里写下Toten认证的代码:如下:

     /// <summary>
    /// 验证服务器Token
    /// </summary>
    public void AuthenticationServer()
    {
        Response.ContentType = "text/plain";
        string token = "heilouword1234";
        if (string.IsNullOrEmpty(token))
        {
            return;
        }
        string echoString = Request.QueryString["echoStr"];
        string signature = Request.QueryString["signature"];
        string timestamp = Request.QueryString["timestamp"];
        string nonce = Request.QueryString["nonce"];
        if (CheckSignature(token, signature, timestamp, nonce))
        {
            if (!string.IsNullOrEmpty(echoString))
            {
                Response.Write(echoString);
                Response.End();
            }
        }
    }

    /// <summary>
    /// 签名验证
    /// </summary>
    /// <param name="token">token</param>
    /// <param name="signature"></param>
    /// <param name="timestamp"></param>
    /// <param name="nonce"></param>
    /// <returns></returns>
    public static bool CheckSignature(string token, string signature, string timestamp, string nonce)
    {
        string[] ArrTmp = { token, timestamp, nonce };
        //字典排序
        Array.Sort(ArrTmp);
        //拼接
        string tmpStr = string.Join("", ArrTmp);
        //sha1验证
        tmpStr = System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(tmpStr, "SHA1");
        //tmpStr = Membership.CreateUser(tmpStr, "SHA1");
        tmpStr = tmpStr.ToLower();
        if (tmpStr == signature)
            return true;
        else
            return false;
    }

获取基础的Access_token

  /// <summary>
    /// 获取Access_token
    /// </summary>
    /// <param name="appid"></param>
    /// <param name="secret"></param>
    /// <returns></returns>
    public string Get_Access_token(string appid, string secret)
    {
        string Url = string.Format("https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid={0}&secret={1}", appid, secret);
        string content = "";
        HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create(Url);
        req.Method = "GET";
        using (WebResponse wr = req.GetResponse())
        {
            HttpWebResponse myResponse = (HttpWebResponse)req.GetResponse();
            StreamReader reader = new StreamReader(myResponse.GetResponseStream(), Encoding.UTF8);
            content = reader.ReadToEnd();//在这里对Access_token 赋值  
        }
        return content;

    }
