}繼續(xù)關注

ResponseMsg(requestXML);方法如下

private

void

ResponseMsg(RequestXML

requestXML)

{

string

MsgType

=

requestXML.MsgType;

try

{

//根據(jù)消息類型判斷發(fā)送何種類型消息

switch

(MsgType)

{

case

"text":

SendTextCase(requestXML);//發(fā)送文本消息

break;

case

"event"://發(fā)送事件消息

if

(!string.IsNullOrWhiteSpace(requestXML.EventName)

&&

requestXML.EventName.ToString().Trim().Equals("subscribe"))

{

SendWelComeMsg(requestXML);//關注時返回的圖文消息

}

else

if

(!string.IsNullOrWhiteSpace(requestXML.EventName)

&&

requestXML.EventName.ToString().Trim().Equals("CLICK"))

{

SendEventMsg(requestXML);//發(fā)送事件消息

}

break;

case

"voice":

SendVoiceMsg(requestXML);//發(fā)送語音消息

break;

case

"location"://發(fā)送位置消息

SendMapMsg(requestXML);

break;

default:

break;

}

}

catch

(Exception

ex)

{

HttpContext.Current.Response.Write(ex.ToString());

}

}先來關注發(fā)送文本消息，SendTextCase(requestXML);//發(fā)送文本消息

///

HttpContext.Current.Response.ContentType

=

"text/xml";

HttpContext.Current.Response.ContentEncoding

=

Encoding.UTF8;

HttpContext.Current.Response.Write(responseContent);

HttpContext.Current.Response.End();

}FormatTextXML方法制定格式

///

string

FormatTextXML(string

string

p3)

{

return

"<xml><ToUserName><![CDATA["

DateTime.Now.Subtract(new

"</CreateTime><MsgType><![CDATA[text]]></MsgType><Content><![CDATA["

}這樣就能實現(xiàn)消息的應答，如果用戶點擊的按鈕，如下代碼：

if

(!string.IsNullOrWhiteSpace(requestXML.EventName)

&&

requestXML.EventName.ToString().Trim().Equals("subscribe"))

{

SendWelComeMsg(requestXML);//關注時返回的圖文消息

}

else

if

(!string.IsNullOrWhiteSpace(requestXML.EventName)

&&

requestXML.EventName.ToString().Trim().Equals("CLICK"))

{

SendEventMsg(requestXML);//發(fā)送事件消息

}
