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-nameWechatServlet/servlet-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
* @author pamchen-1
*
*/
public class ReceiveXmlEntity {
private String ToUserName="";
private String FromUserName="";
private String CreateTime="";
private String MsgType="";
private String MsgId="";
private String Event="";
private String EventKey="";
private String Ticket="";
private String Latitude="";
private String Longitude="";
private String Precision="";
private String PicUrl="";
private String MediaId="";
private String Title="";
private String Description="";
private String Url="";
private String Location_X="";
private String Location_Y="";
private String Scale="";
private String Label="";
private String Content="";
private String Format="";
private String Recognition="";
public String getRecognition() {
return Recognition;
}
public void setRecognition(String recognition) {
Recognition = recognition;
}
public String getFormat() {
return Format;
}
public void setFormat(String format) {
Format = format;
}
public String getContent() {
return Content;
}
public void setContent(String content) {
Content = content;
}
public String getLocation_X() {
return Location_X;
}
public void setLocation_X(String locationX) {
Location_X = locationX;
}
public String getLocation_Y() {
return Location_Y;
}
public void setLocation_Y(String locationY) {
Location_Y = locationY;
}
public String getScale() {
return Scale;
}
public void setScale(String scale) {
Scale = scale;
}
public String getLabel() {
return Label;
}
public void setLabel(String label) {
Label = label;
}
public String getTitle() {
return Title;
}
public void setTitle(String title) {
Title = title;
}
public String getDescription() {
return Description;
}
public void setDescription(String description) {
Description = 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) {
MediaId = mediaId;
}
public String getEventKey() {
return EventKey;
}
public void setEventKey(String eventKey) {
EventKey = eventKey;
}
public String getTicket() {
return Ticket;
}
public void setTicket(String ticket) {
Ticket = ticket;
}
public String getLatitude() {
return Latitude;
}
public void setLatitude(String latitude) {
Latitude = latitude;
}
public String getLongitude() {
return Longitude;
}
public void setLongitude(String longitude) {
Longitude = longitude;
}
public String getPrecision() {
return Precision;
}
public void setPrecision(String precision) {
Precision = 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) {
微信开发平台中有个接口是上传多媒体文件，我用的是java 开发的，我怎么样才能在后台实现呢？代码如下：
/**
* 文件上传到微信服务器
* @param fileType 文件类型
* @param filePath 文件路径
* @return JSONObject
* @throws Exception
*/
public static JSONObject send(String fileType, String filePath) throws Exception {
String result = null;
File file = new File(filePath);
if (!file.exists() || !file.isFile()) {
throw new IOException("文件不存在");
}
/**
* 第一部分
*/
URL urlObj = new URL(""+ getAccess_token() + "type="+fileType+"");
HttpURLConnection con = (HttpURLConnection) urlObj.openConnection();
con.setRequestMethod("POST"); // 以Post方式提交表单，默认get方式
con.setDoInput(true);
con.setDoOutput(true);
con.setUseCaches(false); // post方式不能使用缓存
// 设置请求头信息
con.setRequestProperty("Connection", "Keep-Alive");
con.setRequestProperty("Charset", "UTF-8");
// 设置边界
String BOUNDARY = "----------" + System.currentTimeMillis();
con.setRequestProperty("Content-Type", "multipart/form-data; boundary="+ BOUNDARY);
// 请求正文信息
// 第一部分：
StringBuilder sb = new StringBuilder();
sb.append("--"); // 必须多两道线
sb.append(BOUNDARY);
sb.append("\r\n");
sb.append("Content-Disposition: form-data;name=\"file\";filename=\""+ file.getName() + "\"\r\n");
sb.append("Content-Type:application/octet-stream\r\n\r\n");
byte[] head = sb.toString().getBytes("utf-8");
// 获得输出流
OutputStream out = new DataOutputStream(con.getOutputStream());
// 输出表头
out.write(head);
// 文件正文部分
// 把文件已流文件的方式 推入到url中
DataInputStream in = new DataInputStream(new FileInputStream(file));
int bytes = 0;
byte[] bufferOut = new byte[1024];
while ((bytes = in.read(bufferOut)) != -1) {
out.write(bufferOut, 0, bytes);
}
in.close();
// 结尾部分
byte[] foot = ("\r\n--" + BOUNDARY + "--\r\n").getBytes("utf-8");// 定义最后数据分隔线
out.write(foot);
out.flush();
out.close();
StringBuffer buffer = new StringBuffer();
BufferedReader reader = null;
try {
// 定义BufferedReader输入流来读取URL的响应
reader = new BufferedReader(new InputStreamReader(con.getInputStream()));
String line = null;
while ((line = reader.readLine()) != null) {
//System.out.println(line);
buffer.append(line);
}
if(result==null){
result = buffer.toString();
}
} catch (IOException e) {
System.out.println("发送POST请求出现异常！" + e);
e.printStackTrace();
throw new IOException("数据读取异常");
} finally {
if(reader!=null){
reader.close();
}
}
JSONObject jsonObj =new JSONObject(result);
return jsonObj;
}
java如何创建微信自定义接口
如下：
public static String do_post(String url, ListNameValuePair name_value_pair) throws IOException {
String body = "{}";
DefaultHttpClient httpclient = new DefaultHttpClient();
try {
HttpPost httpost = new HttpPost(url);
httpost.setEntity(new UrlEncodedFormEntity(name_value_pair, StandardCharsets.UTF_8));
HttpResponse response = httpclient.execute(httpost);
HttpEntity entity = response.getEntity();
body = EntityUtils.toString(entity);
} finally {
httpclient.getConnectionManager().shutdown();
}
return body;
}
public static String do_get(String url) throws ClientProtocolException, IOException {
String body = "{}";
DefaultHttpClient httpclient = new DefaultHttpClient();
try {
HttpGet httpget = new HttpGet(url);
HttpResponse response = httpclient.execute(httpget);
HttpEntity entity = response.getEntity();
body = EntityUtils.toString(entity);
} finally {
httpclient.getConnectionManager().shutdown();
}
return body;
}
如何使用微信sdk java版
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?

package com.ansitech.weixin.sdk.util;
import java.security.MessageDigest;
/**

*/
public final class SHA1 {
private static final char[] HEX_DIGITS = {'0', '1', '2', '3', '4', '5',
'6', '7', '8', '9', 'a', 'b', 'c', 'd', 'e', 'f'};
/**
* Takes the raw bytes from the digest and formats them correct.
*
* @param bytes the raw bytes from the digest.
* @return the formatted bytes.
*/
private static String getFormattedText(byte[] bytes) {
int len = bytes.length;
StringBuilder buf = new StringBuilder(len * 2);
// 把密文转换成十六进制的字符串形式
for (int j = 0; j len; j++) {
buf.append(HEX_DIGITS[(bytes[j] 4) 0x0f]);
buf.append(HEX_DIGITS[bytes[j] 0x0f]);
}
return buf.toString();
}
public static String encode(String str) {
if (str == null) {
return null;
}
try {
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。
怎么用java调用微信支付接口
java调用微信支付接口方法：
RequestHandler requestHandler = new RequestHandler(super.getRequest(),super.getResponse());
//获取token //两小时内有效，两小时后重新获取
Token = requestHandler.GetToken();
//更新token 到应用中
requestHandler.getTokenReal();
System.out.println("微信支付获取token=======================:" +Token);
//requestHandler 初始化
requestHandler.init();
requestHandler.init(appid,appsecret, appkey,partnerkey, key);
// --------------------------------本地系统生成订单-------------------------------------
// 设置package订单参数
SortedMapString, String packageParams = new TreeMapString, String();
packageParams.put("bank_type", "WX"); // 支付类型
packageParams.put("body", "xxxx"); // 商品描述
packageParams.put("fee_type", "1"); // 银行币种
packageParams.put("input_charset", "UTF-8"); // 字符集
packageParams.put("notify_url", ""); // 通知地址 这里的通知地址使用外网地址测试，注意80端口是否打开。
packageParams.put("out_trade_no", no); // 商户订单号
packageParams.put("partner", partenerid); // 设置商户号
packageParams.put("spbill_create_ip", super.getRequest().getRemoteHost()); // 订单生成的机器IP，指用户浏览器端IP
packageParams.put("total_fee", String.valueOf(rstotal)); // 商品总金额,以分为单位
// 设置支付参数
SortedMapString, String signParams = new TreeMapString, String();
signParams.put("appid", appid);
signParams.put("noncestr", noncestr);
signParams.put("traceid", PropertiesUtils.getOrderNO());
signParams.put("timestamp", timestamp);
signParams.put("package", packageValue);
signParams.put("appkey", this.appkey);
// 生成支付签名，要采用URLENCODER的原始值进行SHA1算法！
String sign ="";
try {
sign = Sha1Util.createSHA1Sign(signParams);
} catch (Exception e) {
e.printStackTrace();
}
// 增加非参与签名的额外参数
signParams.put("sign_method", "sha1");
signParams.put("app_signature", sign);
// api支付拼包结束------------------------------------
//获取prepayid
String prepayid = requestHandler.sendPrepay(signParams);
System.out.println("prepayid :" + prepayid);
// --------------------------------生成完成---------------------------------------------
//生成预付快订单完成，返回给android,ios 掉起微信所需要的参数。
SortedMapString, String payParams = new TreeMapString, String();
payParams.put("appid", appid);
payParams.put("noncestr", noncestr);
payParams.put("package", "Sign=WXPay");
payParams.put("partnerid", partenerid);
payParams.put("prepayid", prepayid);
payParams.put("appkey", this.appkey);
//这里除1000 是因为参数长度限制。
int time = (int) (System.currentTimeMillis() / 1000);
payParams.put("timestamp",String.valueOf(time));
System.out.println("timestamp:" + time);
//签名
String paysign ="";
try {
paysign = Sha1Util.createSHA1Sign(payParams);
} catch (Exception e) {
e.printStackTrace();
}
payParams.put("sign", paysign);
//拼json 数据返回给客户端
BasicDBObject backObject = new BasicDBObject();
backObject.put("appid", appid);
backObject.put("noncestr", payParams.get("noncestr"));
backObject.put("package", "Sign=WXPay");
backObject.put("partnerid", payParams.get("partnerid"));
backObject.put("prepayid", payParams.get("prepayid"));
backObject.put("appkey", this.appkey);
backObject.put("timestamp",payParams.get("timestamp"));
backObject.put("sign",payParams.get("sign"));
String backstr = dataObject.toString();
System.out.println("backstr:" + backstr);
return backstr;
====================到此为止，预付款订单已生成，并且已返回客户端====================
//坐等微信服务器通知，通知的地址就是生成预付款订单的notify_url
ResponseHandler resHandler = new ResponseHandler(request, response);
resHandler.setKey(partnerkey);
//创建请求对象
//RequestHandler queryReq = new RequestHandler(request, response);
//queryReq.init();
if (resHandler.isTenpaySign() == true) {
//商户订单号
String out_trade_no = resHandler.getParameter("out_trade_no");
System.out.println("out_trade_no:" + out_trade_no);
//财付通订单号
String transaction_id = resHandler.getParameter("transaction_id");
System.out.println("transaction_id:" + transaction_id);
//金额,以分为单位
String total_fee = resHandler.getParameter("total_fee");
//如果有使用折扣券，discount有值，total_fee+discount=原请求的total_fee
String discount = resHandler.getParameter("discount");
//支付结果
String trade_state = resHandler.getParameter("trade_state");
//判断签名及结果
if ("0".equals(trade_state)) {
//------------------------------
//即时到账处理业务开始
//------------------------------
System.out.println("----------------业务逻辑执行-----------------");
//——请根据您的业务逻辑来编写程序（以上代码仅作参考）——
System.out.println("----------------业务逻辑执行完毕-----------------");
System.out.println("success"); // 请不要修改或删除
System.out.println("即时到账支付成功");
//给财付通系统发送成功信息，财付通系统收到此结果后不再进行后续通知
resHandler.sendToCFT("success");
//给微信服务器返回success 否则30分钟通知8次
return "success";
}else{
System.out.println("通知签名验证失败");
resHandler.sendToCFT("fail");
response.setCharacterEncoding("utf-8");
}
}else {
System.out.println("fail -Md5 failed");
