說明：
本次的教程主要是對(duì)微信公眾平臺(tái)開發(fā)者模式的講解，網(wǎng)絡(luò)上很多類似文章，但很多都讓初學(xué)微信開發(fā)的人一頭霧水，所以總結(jié)自己的微信開發(fā)經(jīng)驗(yàn)，將微信開發(fā)的整個(gè)過程系統(tǒng)的列出，并對(duì)主要代碼進(jìn)行講解分析，讓初學(xué)者盡快上手。
在閱讀本文之前，應(yīng)對(duì)微信公眾平臺(tái)的官方開發(fā)文檔有所了解，知道接收和發(fā)送的都是xml格式的數(shù)據(jù)。另外，在做內(nèi)容回復(fù)時(shí)用到了圖靈機(jī)器人的api接口，這是一個(gè)自然語言解析的開放平臺(tái)，可以幫我們解決整個(gè)微信開發(fā)過程中最困難的問題，此處不多講，下面會(huì)有其詳細(xì)的調(diào)用方式。
1.1 在登錄微信官方平臺(tái)之后，開啟開發(fā)者模式，此時(shí)需要我們填寫url和token，所謂url就是我們自己服務(wù)器的接口，用WechatServlet.java來實(shí)現(xiàn)，相關(guān)解釋已經(jīng)在注釋中說明，代碼如下：
[java]?view plain?copy
package?demo.servlet;
import?java.io.BufferedReader;
import?java.io.IOException;
import?java.io.InputStream;
import?java.io.InputStreamReader;
import?java.io.OutputStream;
import?javax.servlet.ServletException;
import?javax.servlet.http.HttpServlet;
import?javax.servlet.http.HttpServletRequest;
import?javax.servlet.http.HttpServletResponse;
import?demo.process.WechatProcess;
/**
*?微信服務(wù)端收發(fā)消息接口
*
*?@author?pamchen-1
*
*/
public?class?WechatServlet?extends?HttpServlet?{
/**
*?The?doGet?method?of?the?servlet.?br
*
*?This?method?is?called?when?a?form?has?its?tag?value?method?equals?to?get.
*
*?@param?request
*????????????the?request?send?by?the?client?to?the?server
*?@param?response
*????????????the?response?send?by?the?server?to?the?client
*?@throws?ServletException
*?????????????if?an?error?occurred
*?@throws?IOException
*?????????????if?an?error?occurred
*/
public?void?doGet(HttpServletRequest?request,?HttpServletResponse?response)
throws?ServletException,?IOException?{
request.setCharacterEncoding("UTF-8");
response.setCharacterEncoding("UTF-8");
/**?讀取接收到的xml消息?*/
StringBuffer?sb?=?new?StringBuffer();
InputStream?is?=?request.getInputStream();
InputStreamReader?isr?=?new?InputStreamReader(is,?"UTF-8");
BufferedReader?br?=?new?BufferedReader(isr);
String?s?=?"";
while?((s?=?br.readLine())?!=?null)?{
sb.append(s);
}
String?xml?=?sb.toString();?//次即為接收到微信端發(fā)送過來的xml數(shù)據(jù)
String?result?=?"";
/**?判斷是否是微信接入激活驗(yàn)證，只有首次接入驗(yàn)證時(shí)才會(huì)收到echostr參數(shù)，此時(shí)需要把它直接返回?*/
String?echostr?=?request.getParameter("echostr");
if?(echostr?!=?null??echostr.length()??1)?{
result?=?echostr;
}?else?{
//正常的微信處理流程
result?=?new?WechatProcess().processWechatMag(xml);
}
try?{
OutputStream?os?=?response.getOutputStream();
os.write(result.getBytes("UTF-8"));
os.flush();
os.close();
}?catch?(Exception?e)?{
e.printStackTrace();
}
}
/**
*?The?doPost?method?of?the?servlet.?br
*
*?This?method?is?called?when?a?form?has?its?tag?value?method?equals?to
*?post.
*

*????????????the?request?send?by?the?client?to?the?server
*?@param?response
*????????????the?response?send?by?the?server?to?the?client
*?@throws?ServletException
*?????????????if?an?error?occurred
*?@throws?IOException
*?????????????if?an?error?occurred
*/
public?void?doPost(HttpServletRequest?request,?HttpServletResponse?response)
throws?ServletException,?IOException?{
doGet(request,?response);
}
}
1.2 相應(yīng)的web.xml配置信息如下，在生成WechatServlet.java的同時(shí)，可自動(dòng)生成web.xml中的配置。前面所提到的url處可以填寫例如：http;//服務(wù)器地址/項(xiàng)目名/wechat.do
[html]?view plain?copy
?xml?version="1.0"?encoding="UTF-8"?
web-app?version="2.5"
xmlns=""
xmlns:xsi=""
xsi:schemaLocation="

1.3 通過以上代碼，我們已經(jīng)實(shí)現(xiàn)了微信公眾平臺(tái)開發(fā)的框架，即開通開發(fā)者模式并成功接入、接收消息和發(fā)送消息這三個(gè)步驟。
下面就講解其核心部分——解析接收到的xml數(shù)據(jù)，并以文本類消息為例，通過圖靈機(jī)器人api接口實(shí)現(xiàn)智能回復(fù)。
2.1 首先看一下整體流程處理代碼，包括：xml數(shù)據(jù)處理、調(diào)用圖靈api、封裝返回的xml數(shù)據(jù)。
[java]?view plain?copy
package?demo.process;
import?java.util.Date;
import?demo.entity.ReceiveXmlEntity;
/**
*?微信xml消息處理流程邏輯類
*?@author?pamchen-1
*
*/
public?class?WechatProcess?{
/**
*?解析處理xml、獲取智能回復(fù)結(jié)果（通過圖靈機(jī)器人api接口）
*?@param?xml?接收到的微信數(shù)據(jù)
*?@return??最終的解析結(jié)果（xml格式數(shù)據(jù)）
*/
public?String?processWechatMag(String?xml){
/**?解析xml數(shù)據(jù)?*/
ReceiveXmlEntity?xmlEntity?=?new?ReceiveXmlProcess().getMsgEntity(xml);
/**?以文本消息為例，調(diào)用圖靈機(jī)器人api接口，獲取回復(fù)內(nèi)容?*/
String?result?=?"";
if("text".endsWith(xmlEntity.getMsgType())){
result?=?new?TulingApiProcess().getTulingResult(xmlEntity.getContent());
}
/**?此時(shí)，如果用戶輸入的是“你好”，在經(jīng)過上面的過程之后，result為“你也好”類似的內(nèi)容
*??因?yàn)樽罱K回復(fù)給微信的也是xml格式的數(shù)據(jù)，所有需要將其封裝為文本類型返回消息
*?*/
result?=?new?FormatXmlProcess().formatXmlAnswer(xmlEntity.getFromUserName(),?xmlEntity.getToUserName(),?result);
return?result;
}
}
2.2 解析接收到的xml數(shù)據(jù)，此處有兩個(gè)類，ReceiveXmlEntity.java和ReceiveXmlProcess.java，通過反射的機(jī)制動(dòng)態(tài)調(diào)用實(shí)體類中的set方法，可以避免很多重復(fù)的判斷，提高代碼效率，代碼如下：
[java]?view plain?copy
package?demo.entity;
/**
*?接收到的微信xml實(shí)體類
*?@author?pamchen-1

沒有辦法的.微信內(nèi)的瀏覽器,它里面也只是一個(gè)HTML頁面,HTML頁面是沒辦法調(diào)用用戶機(jī)器上的瀏覽器的.
如果通過頁面就能調(diào)用用戶手機(jī)上的軟件.那系統(tǒng)早就不安全了.
