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="

descriptionThis is the description of my J2EE component/description

display-nameThis is the display name of my J2EE component/display-name

servlet-nameWechatServlet/servlet-name

/servlet

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;

/**

* @author qsyangyangqisheng274@163.com

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");
