这个代码可能比较多。。看微信公众平台的api,里面写的很清楚,其实就是一个http请求,加上指定的报文就可以了,用java写还比较简单的。。
让客户满意是我们工作的目标,不断超越客户的期望值来自于我们对这个行业的热爱。我们立志把好的技术通过有效、简单的方式提供给客户,将通过不懈努力成为客户在信息化领域值得信任、有价值的长期合作伙伴,公司提供的服务项目有:域名注册、虚拟空间、营销软件、网站建设、甘南网站维护、网站推广。

net的我有 java的还没看呢 给你说说原理 通过开发者id 或者关注者列表 然后通过用户openid(用户唯一标示)向用户发送客服消息 他这个通道是走的客服消息 ,前提是必须关注者主动向公众号发过消息 时限为24h
1.首先我们新建一个Java开发包WeiXinSDK
2.包路径:com.ansitech.weixin.sdk
测试的前提条件:
假如我的公众账号微信号为:vzhanqun
我的服务器地址为:
下面我们需要新建一个URL的请求地址
我们新建一个Servlet来验证URL的真实性,具体接口参考
接入指南
3.新建com.ansitech.weixin.sdk.WeixinUrlFilter.java
这里我们主要是获取微信服务器法师的验证信息,具体验证代码如下
[java] view plain copy print?
package com.ansitech.weixin.sdk;
import com.ansitech.weixin.sdk.util.SHA1;
import java.io.IOException;
import java.util.ArrayList;
import java.util.Collections;
import java.util.Comparator;
import java.util.List;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class WeixinUrlFilter implements Filter {
//这个Token是给微信开发者接入时填的
//可以是任意英文字母或数字,长度为3-32字符
private static String Token = "vzhanqun1234567890";
@Override
public void init(FilterConfig config) throws ServletException {
System.out.println("WeixinUrlFilter启动成功!");
}
@Override
public void doFilter(ServletRequest req, ServletResponse res,
FilterChain chain) throws IOException, ServletException {
HttpServletRequest request = (HttpServletRequest) req;
HttpServletResponse response = (HttpServletResponse) res;
//微信服务器将发送GET请求到填写的URL上,这里需要判定是否为GET请求
boolean isGet = request.getMethod().toLowerCase().equals("get");
System.out.println("获得微信请求:" + request.getMethod() + " 方式");
if (isGet) {
//验证URL真实性
String signature = request.getParameter("signature");// 微信加密签名
String timestamp = request.getParameter("timestamp");// 时间戳
String nonce = request.getParameter("nonce");// 随机数
String echostr = request.getParameter("echostr");//随机字符串
ListString params = new ArrayListString();
params.add(Token);
params.add(timestamp);
params.add(nonce);
//1. 将token、timestamp、nonce三个参数进行字典序排序
Collections.sort(params, new ComparatorString() {
@Override
public int compare(String o1, String o2) {
return o1.compareTo(o2);
}
});
//2. 将三个参数字符串拼接成一个字符串进行sha1加密
String temp = SHA1.encode(params.get(0) + params.get(1) + params.get(2));
if (temp.equals(signature)) {
response.getWriter().write(echostr);
}
} else {
//处理接收消息
}
}
@Override
public void destroy() {
}
}
好了,不过这里有个SHA1算法,我这里也把SHA1算法的源码给贴出来吧!
4.新建com.ansitech.weixin.sdk.util.SHA1.java
[java] view plain copy print?

public final class SHA1 {

for (int j = 0; j len; j++) {

return buf.toString();
}

MessageDigest messageDigest = MessageDigest.getInstance("SHA1");
messageDigest.update(str.getBytes());
return getFormattedText(messageDigest.digest());
} catch (Exception e) {
throw new RuntimeException(e);
}
}
}
5.把这个Servlet配置到web.xml中
[html] view plain copy print?
filter
description微信消息接入接口/description
filter-nameWeixinUrlFilter/filter-name
filter-classcom.ansitech.weixin.sdk.WeixinUrlFilter/filter-class
/filter
filter-mapping
filter-nameWeixinUrlFilter/filter-name
url-pattern/api/vzhanqun/url-pattern
/filter-mapping
好了,接入的开发代码已经完成。
6.下面就把地址URL和密钥Token填入到微信申请成为开发者模式中吧。
说明:
本次的教程主要是对微信公众平台开发者模式的讲解,网络上很多类似文章,但很多都让初学微信开发的人一头雾水,所以总结自己的微信开发经验,将微信开发的整个过程系统的列出,并对主要代码进行讲解分析,让初学者尽快上手。
在阅读本文之前,应对微信公众平台的官方开发文档有所了解,知道接收和发送的都是xml格式的数据。另外,在做内容回复时用到了图灵机器人的api接口,这是一个自然语言解析的开放平台,可以帮我们解决整个微信开发过程中最困难的问题,此处不多讲,下面会有其详细的调用方式。
1.1 在登录微信官方平台之后,开启开发者模式,此时需要我们填写url和token,所谓url就是我们自己服务器的接口,用WechatServlet.java来实现,相关解释已经在注释中说明,代码如下:
[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;
/**
* 微信服务端收发消息接口
*
* @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");
/** 读取接收到的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(); //次即为接收到微信端发送过来的xml数据
String result = "";
/** 判断是否是微信接入激活验证,只有首次接入验证时才会收到echostr参数,此时需要把它直接返回 */
String echostr = request.getParameter("echostr");
if (echostr != null echostr.length() 1) {
result = echostr;
} else {
//正常的微信处理流程
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.
*
* @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 doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doGet(request, response);
}
}
1.2 相应的web.xml配置信息如下,在生成WechatServlet.java的同时,可自动生成web.xml中的配置。前面所提到的url处可以填写例如:http;//服务器地址/项目名/wechat.do
[html] view plain copy
?xml version="1.0" encoding="UTF-8"?
web-app version="2.5"
xmlns=""
xmlns:xsi=""
xsi:schemaLocation="
"
servlet
descriptionThis is the description of my J2EE component/description
display-nameThis is the display name of my J2EE component/display-name

url-pattern/wechat.do/url-pattern
/servlet-mapping
welcome-file-list
welcome-fileindex.jsp/welcome-file
/welcome-file-list
/web-app
1.3 通过以上代码,我们已经实现了微信公众平台开发的框架,即开通开发者模式并成功接入、接收消息和发送消息这三个步骤。
下面就讲解其核心部分——解析接收到的xml数据,并以文本类消息为例,通过图灵机器人api接口实现智能回复。
2.1 首先看一下整体流程处理代码,包括:xml数据处理、调用图灵api、封装返回的xml数据。
[java] view plain copy
package demo.process;
import java.util.Date;
import demo.entity.ReceiveXmlEntity;
/**
* 微信xml消息处理流程逻辑类
* @author pamchen-1
*
*/
public class WechatProcess {
/**
* 解析处理xml、获取智能回复结果(通过图灵机器人api接口)
* @param xml 接收到的微信数据
* @return 最终的解析结果(xml格式数据)
*/
public String processWechatMag(String xml){
/** 解析xml数据 */
ReceiveXmlEntity xmlEntity = new ReceiveXmlProcess().getMsgEntity(xml);
/** 以文本消息为例,调用图灵机器人api接口,获取回复内容 */
String result = "";
if("text".endsWith(xmlEntity.getMsgType())){
result = new TulingApiProcess().getTulingResult(xmlEntity.getContent());
}
/** 此时,如果用户输入的是“你好”,在经过上面的过程之后,result为“你也好”类似的内容
* 因为最终回复给微信的也是xml格式的数据,所有需要将其封装为文本类型返回消息
* */
result = new FormatXmlProcess().formatXmlAnswer(xmlEntity.getFromUserName(), xmlEntity.getToUserName(), result);
return result;
}
}
2.2 解析接收到的xml数据,此处有两个类,ReceiveXmlEntity.java和ReceiveXmlProcess.java,通过反射的机制动态调用实体类中的set方法,可以避免很多重复的判断,提高代码效率,代码如下:
[java] view plain copy
package demo.entity;
/**
* 接收到的微信xml实体类

*

}

return Description;
}
public void setDescription(String description) {

}
public String getUrl() {
return Url;
}
public void setUrl(String url) {
Url = url;
}
public String getPicUrl() {
return PicUrl;
}
public void setPicUrl(String picUrl) {
PicUrl = picUrl;
}
public String getMediaId() {
return MediaId;
}
public void setMediaId(String mediaId) {

}
public String getEventKey() {

}
public void setEventKey(String eventKey) {

}
public String getPrecision() {

}
public void setPrecision(String precision) {

}
public String getEvent() {
return Event;
}
public void setEvent(String event) {
Event = event;
}
public String getMsgId() {
return MsgId;
}
public void setMsgId(String msgId) {
MsgId = msgId;
}
public String getToUserName() {
return ToUserName;
}
public void setToUserName(String toUserName) {
java。微信卡死的代码是java,就是发送代码到微信中,只要用户点击了代码里的黑色小球,那么就会让微信强制卡死不能操作,只能通过结束进程来解决。
