上一篇已經(jīng)搭建好整體框架，實現(xiàn)了入口的驗證， ? 驗證通過後就交給LookMsgType方法處理，LookMsgType方法主要是對微信發(fā)來的不同的訊息進行分解，不同的類型交給業(yè)務(wù)邏輯層不同的方法處理， ? 對不同類型的訊息判斷，可以用if，也可以用switch ? 一般來說超過5個的if用switch會更好， 這裡貼出LookMsgType方法：

????????????switch?(msgType)

外層switch判斷msgtype， ? 在event類型時，再次switch判斷特定的事件類型（追蹤、取消追蹤、自訂選單事件等）， ?至此所有的微信發(fā)來的訊息都有處理了，在上面程式碼中用到訊息模型以及ReadXml.GetModel方法給模型賦值， 賦值之後傳遞給業(yè)務(wù)邏輯層對應(yīng)的方法處理， ?下面寫出訊息封裝和給模型賦值的方法。

? ? 1、訊息封裝： ? ??

? ? ? ? ? ?對所有微型訊號傳送來的訊息進行封裝，datamodel中建立一個Receive資料夾和一個send資料夾，在其中分別建立一個資料夾的類，對應(yīng)於訊息完成之後，完整的datamodel類別庫如下圖：

範例

-----接收訊息：

文字訊息RText .cs

public?class?RText
????{
????????public?string?ToUserName?{?get;?set;?}//?開發(fā)者微信號
????????public?string?FromUserName?{?get;?set;?}//?用戶號（OpenID）
????????public?long?CreateTime?{?get;?set;?}//?創(chuàng)建時間
????????public?string?MsgType?{?get;?set;?}?//消息類型
????????public?string?Content?{?get;?set;?}//內(nèi)容
????????public?long?MsgId?{?get;?set;?}//消息ID

????}

自訂選單點擊RMenuClick.cs

public?class?RMenuClick
????{
????????public?string?ToUserName?{?get;?set;?}//?開發(fā)者微信號
????????public?string?FromUserName?{?get;?set;?}//?用戶號（OpenID）
????????public?long?CreateTime?{?get;?set;?}//?創(chuàng)建時間
????????public?string?MsgType?{?get;?set;?}?//消息類型

????????public?string?Event?{?get;?set;?}//事件類型
????????public?string?EventKey?{?get;?set;?}//事件key
????????
????}

#其他也都類似，不一一列舉。

-----發(fā)送訊息

?

發(fā)送文字訊息SText.cs

public?class?SText
????{



????????public?string?ToUserName?{?get;?set;?}//?用戶號（OpenID）
????????public?string?FromUserName?{?get;?set;?}//?開發(fā)者微信號

????????public?long?CreateTime?{?get;?set;?}//?創(chuàng)建時間

????????public?string?MsgType?{?get?{?return?"text";?}?}?//消息類型

????????public?string?Content?{?get;?set;?}//內(nèi)容


????}

SText

傳送圖文訊息SNews.cs

namespace?DataModel.Send
{
????public?class?SNews
????{
????????public?string?ToUserName?{?get;?set;?}//?用戶號（OpenID）
????????public?string?FromUserName?{?get;?set;?}//?開發(fā)者微信號

????????public?long?CreateTime?{?get;?set;?}//?創(chuàng)建時間

????????public?string?MsgType?{?get?{?return?"news";?}?}?//消息類型

????????public?int?ArticleCount?{?get;?set;?}//圖文個數(shù)

????????public?List<articlesmodel>?Articles?{?get;?set;?}//圖文列表
????}
????public?class?ArticlesModel?//默認第一條大圖顯示
????{
????????public?string?Title?{?get;?set;?}//標題
????????public?string?Description?{?get;?set;?}//描述
????????public?string?PicUrl?{?get;?set;?}//圖片鏈接??
????????public?string?Url?{?get;?set;?}//點擊之后跳轉(zhuǎn)的鏈接

????}
}</articlesmodel>

在發(fā)送圖文訊息中，因為回覆給微信的圖文訊息中，具體的圖文內(nèi)容是多條（最多可以10條），所以單獨會有ArticlesModel。 ? ?後面文章會寫出圖文訊息的發(fā)送。

? ? ?2、透過反射給model賦值?

? ? ? ?在上篇文章寫的入口處，已經(jīng)有了解析xml的方法，現(xiàn)在封裝了訊息，通常的做法，是每次用到對應(yīng)的model就手動寫程式碼賦值， ?而我這裡LookMsgType方法中所有給訊息賦值時全用的ReadXml.GetModel這同一個方法， ?這裡用的就是反射，方法如下：

///?<summary>
????????///?通過反射給接收消息model賦值
????????///?</summary>
????????///?<typeparam></typeparam>
????????///?<param>
????????///?<returns></returns>
????????public?static?T?GetModel<t>(T?model,?Dictionary<string>?xmlModel)?where?T?:?class
????????{
????????????var?m?=?model.GetType();
????????????foreach?(PropertyInfo?p?in?m.GetProperties())
????????????{
????????????????string?name?=?p.Name;
????????????????if?(xmlModel.Keys.Contains(name))
????????????????{
????????????????????string?value=xmlModel.Where(x?=>?x.Key?==?name).FirstOrDefault().Value;
????????????????????p.SetValue(model,
????????????????????string.IsNullOrEmpty(value)???null?:?Convert.ChangeType(value,?p.PropertyType),?null);?
????????????????}
????????????}
????????????return?model;
????????}</string></t>

T model 就是要使用的訊息類， ? xmlmodel是在入口處傳遞進來的解析的微信發(fā)來的xml訊息， ?這樣，就不需要每次手動寫程式碼賦值了。

好了，此篇實作了lookmsgtype方法， 實作了訊息封裝與反射賦值，接下去就是到了業(yè)務(wù)邏輯層中的處理與具體實作了...
