十四老久没有写博客了，中间经历了，事业，感情的几分波折。现在终于稍微缓过来一点。又是一次从头开始，走在匆忙的路上。
好了煽情完了，直接上代码了。
基础就不说了我用的是vs2005开发的,部署在iis6.0上，微信号为：ruyishh。目前只是简单的功能。
/// <summary> /// 获取access_token /// </summary> /// <returns></returns> public static string GetAccessToken() { WebClient webClient = new WebClient(); Byte[] bytes = webClient.DownloadData(string.Format("{0}&appid={1}&secret={2}", m_AcessTokenUrl, m_appid, m_secret)); string result = Encoding.GetEncoding("utf-8").GetString(bytes); //JObject jObj = JObject.Parse(result); //JToken token = jObj["access_token"]; //return token.ToString().Substring(1, token.ToString().Length - 2); string []temp = result.Split(','); string[] tp = temp[0].Split(':'); return tp[1].ToString().Replace('"',' ').Trim().ToString(); }
关于access_token呢 我理解就相当于一个全局session吧，每次获取一个，上一个就会过期失效，开发文档上说的有效期为30天吧。至于access_token的作用呢，可以用来创建自定义菜单。
#region //创建自定义菜单 注意Json格式问题 private void CreateWxMenu() { string weixin1 = ""; weixin1 += "{ "; weixin1 += ""button":[ "; weixin1 += "{ "; // weixin1 += ""type":"click", "; //第一个菜单 weixin1 += ""name":"故障维修", "; weixin1 += ""sub_button":[ "; weixin1 += "{ "; weixin1 += ""type":"click", "; weixin1 += ""name":"宽带故障", "; weixin1 += ""key":"V1001_REPAIRBAND" "; weixin1 += "}, "; weixin1 += "{ "; weixin1 += ""type":"click", "; weixin1 += ""name":"固话故障", "; weixin1 += ""key":"V1001_REPAIRPHONE" "; weixin1 += "}] "; weixin1 += "}, "; //第二个菜单 weixin1 += "{ "; //weixin1 += ""type":"click", "; weixin1 += ""name":"查询服务", "; weixin1 += ""sub_button":[ "; weixin1 += "{ "; weixin1 += ""type":"click", "; weixin1 += ""name":"话费余额", "; weixin1 += ""key":"V1002_TELQUERY" "; weixin1 += "}, "; weixin1 += "{ "; weixin1 += ""type":"click", "; weixin1 += ""name":"流量查询", "; weixin1 += ""key":"V1002_FLOWQUERY" "; weixin1 += "}, "; weixin1 += "{ "; weixin1 += ""type":"click", "; weixin1 += ""name":"积分查询", "; weixin1 += ""key":"V1002_TOTALQUERY" "; weixin1 += "}, "; weixin1 += "{ "; weixin1 += ""type":"click", "; weixin1 += ""name":"账单查询", "; weixin1 += ""key":"V1002_LISTQUERY" "; weixin1 += "}] "; weixin1 += "}, "; //第三个菜单 weixin1 += "{ "; weixin1 += ""name":"套餐服务", "; weixin1 += ""sub_button":[ "; weixin1 += "{ "; weixin1 += ""type":"click", "; weixin1 += ""name":"最新业务", "; weixin1 += ""key":"V1003_NEWS" "; weixin1 += "}, "; weixin1 += "{ "; weixin1 += ""type":"click", "; weixin1 += ""name":"流量套餐", "; weixin1 += ""key":"V1003_SETMEAL" "; weixin1 += "}, "; weixin1 += "{ "; weixin1 += ""type":"click", "; weixin1 += ""name":"短信套餐", "; weixin1 += ""key":"V1003_MESSAGE" "; weixin1 += "}] "; weixin1 += "} "; weixin1 += "}] "; weixin1 += "} "; PostMenuData( postUrl+GetAccessToken(),weixin1 ); } private void PostMenuData(string url, string postData) { Stream outstream = null; Stream instream = null; StreamReader sr = null; HttpWebResponse response = null; HttpWebRequest request = null; Encoding encoding = Encoding.UTF8; byte[] data = encoding.GetBytes(postData); // 准备请求... try { // 设置参数 request = WebRequest.Create(url) as HttpWebRequest; CookieContainer cookieContainer = new CookieContainer(); request.CookieContainer = cookieContainer; request.AllowAutoRedirect = true; request.Method = "POST"; request.ContentType = "application/x-www-form-urlencoded"; request.ContentLength = data.Length; outstream = request.GetRequestStream(); outstream.Write(data, 0, data.Length); outstream.Close(); //发送请求并获取相应回应数据 response = request.GetResponse() as HttpWebResponse; //直到request.GetResponse()程序才开始向目标网页发送Post请求 instream = response.GetResponseStream(); sr = new StreamReader(instream, encoding); //返回结果网页（html）代码 string content = sr.ReadToEnd(); string err = string.Empty; // return content; } catch (Exception ex) { string err = ex.Message; //return string.Empty; } }
关系图我就不画了，运行逻辑呢就是这样： 微信用户 <> 腾讯微信服务器 <> 我的程序
对于处理程序代码如下：
protected void Page_Load(object sender, EventArgs e) { if (Request.HttpMethod.ToLower() == "post") { Stream s = System.Web.HttpContext.Current.Request.InputStream; byte[] b = new byte[s.Length]; s.Read(b, 0, (int)s.Length); postStr = Encoding.UTF8.GetString(b); if (!string.IsNullOrEmpty(postStr)) { ResponseMsg(); //对微信服务器psot形式发来的消息进行处理 } } else { string echoStr = System.Web.HttpContext.Current.Request.QueryString["echoStr"]; if (CheckSignature()) { if( !string.IsNullOrEmpty( echoStr ) ) System.Web.HttpContext.Current.Response.Write(echoStr); //返回原值表示校验成功 System.Web.HttpContext.Current.Response.End(); } } } //返回微信信息 private void ResponseMsg() { 在此写你的处理代码 }
