.Net开发微信公众平台之自定义菜单代码详解
这篇文章主要为大家详细解析了微信公众平台开发之自定义菜单.Net代码,感兴趣的小伙伴们可以参考一下
用户自定义菜单制作时,需要用到access_token,我们直接使用前面讲解的IsExistAccess_Token()函数。我理解的微信公共平台里面菜单分为button和sub_button,即菜单和子菜单,这些菜单都有一个name的属性,类别分为click和view,click类有key属性;而view类有url属性,含有子菜单的菜单没有key属性也没有url属性。这些情况可以从下面的例子看出来。 public void MyMenu(){string weixin1 = "";weixin1 = @" {""button"":[{""type"":""click"",""name"":""你好!"",""key"":""Hello""},{""type"":""view"",""name"":""公司简介"",""url"":""http://www.4ugood.net""},{""name"":""产品介绍"",""sub_button"":[{""type"":""click"",""name"":""产品1"",""key"":""P1""},{""type"":""click"",""name"":""产品2"",""key"":""P2""}]}] }";string access_token = IsExistAccess_Token();string i = GetPage("https://api.weixin.qq.com/cgi-bin/menu/create?access_token="+access_token, weixin1);Response.Write(i);}在你页面的 Page_Load 函数中调用这个MyMenu(),就可以显示出来了。既然显示出来了,菜单的时间如何出发呢?我们已经了解到了如果类型为view的话,他有url属性,这个不需要处理,点击后会直接跳转到你设定的url的页面,下面我来看看如何触发click吧,按照微信的文档可以用(!string.IsNullOrEmpty(wx.EventName) && wx.EventName.Trim() == "CLICK")来判断,我把之前的代码改造一下,同时把在GetWxMessage()方法中把EventKey的值附上,wx.EventKey = xml.SelectSingleNode("xml").SelectSingleNode("EventKey").InnerText;protected void Page_Load(object sender, EventArgs e){MyMenu();wxmessage wx = GetWxMessage();string res = "";if (!string.IsNullOrEmpty(wx.EventName) && wx.EventName.Trim() == "subscribe"){string content = "";content = "/:rose欢迎北京永杰友信科技有限公司/:rosen直接回复“你好”";res = sendTextMessage(wx, content);}else if (!string.IsNullOrEmpty(wx.EventName) && wx.EventName.Trim() == "CLICK"){if(wx.EventKey=="Hello")res = sendTextMessage(wx, "你好,欢迎使用北京永杰友信科技有限公司公共微信平台!");if(wx.EventKey=="P1")res = sendTextMessage(wx, "你好,点击了产品1");if(wx.EventKey=="P2")res = sendTextMessage(wx, "你好,点击了产品2");}else{if (wx.MsgType == "text" && wx.Content == "你好"){res = sendTextMessage(wx, "你好,欢迎使用北京永杰友信科技有限公司公共微信平台!");}else if (wx.MsgType == "voice"){res = sendTextMessage(wx, wx.Recognition);}else{res = sendTextMessage(wx, "你好,未能识别消息!");}}Response.Write(res);}private wxmessage GetWxMessage(){wxmessage wx = new wxmessage();StreamReader str = new StreamReader(Request.InputStream, System.Text.Encoding.UTF8);XmlDocument xml = new XmlDocument();xml.Load(str);wx.ToUserName = xml.SelectSingleNode("xml").SelectSingleNode("ToUserName").InnerText;wx.FromUserName = xml.SelectSingleNode("xml").SelectSingleNode("FromUserName").InnerText;wx.MsgType = xml.SelectSingleNode("xml").SelectSingleNode("MsgType").InnerText;if (wx.MsgType.Trim() == "text"){wx.Content = xml.SelectSingleNode("xml").SelectSingleNode("Content").InnerText;}if (wx.MsgType.Trim() == "event"){wx.EventName = xml.SelectSingleNode("xml").SelectSingleNode("Event").InnerText;wx.EventKey = xml.SelectSingleNode("xml").SelectSingleNode("EventKey").InnerText;}if (wx.MsgType.Trim() == "voice"){wx.Recognition = xml.SelectSingleNode("xml").SelectSingleNode("Recognition").InnerText;}return wx;}/// <summary>/// 发送文字消息/// </summary>/// <param name="wx">获取的收发者信息</param>/// <param name="content">内容</param>/// <returns></returns>private string sendTextMessage(wxmessage wx, string content){string res = string.Format(@"<xml><ToUserName><![CDATA[{0}]]></ToUserName><FromUserName><![CDATA[{1}]]></FromUserName><CreateTime>{2}</CreateTime><MsgType><![CDATA[text]]></MsgType><Content><![CDATA[{3}]]></Content></xml> ",wx.FromUserName, wx.ToUserName, DateTime.Now, content);return res;} 这样就可以相应你的菜单事件了,我上面的代码写的有很多可以优化的地方,这里主要以简介为主,以后我们会逐渐搭建起一个微信公共平台的.net框架,什么菜单类,消息类等等。以上就是.Net开发微信公众平台之自定义菜单代码详解的详细内容,更多请关注小潘博客其它相关文章!
