微信消息推送详解

微信模版消息推送详解

1. 应用企业注册微信公众号并认证https://mp.weixin.qq.com

2. 登录微信公众号获取appID和appsecret本次使用的测试帐号进行说明

    

3. 扫码关注和新建消息模版拿到openid作为我们推送的对象

    

   4、查看官方开发文档https://mp.weixin.qq.com/debug/cgi-bin/readtmpl?t=tmplmsg/faq_tmpl

    

1. 开始撸代码

   创建工具类

   TestWechatMsg.java

    

    

   package testWeb;

    

   import java.io.BufferedReader;

   import java.io.IOException;

   import java.io.InputStreamReader;

   import java.io.OutputStreamWriter;

   import java.net.HttpURLConnection;

   import java.net.MalformedURLException;

   import java.net.URL;

   import java.net.URLConnection;

   import java.util.HashMap;

   import java.util.Map;

    

   import com.alibaba.fastjson.JSON;

    

   import testWeb.bean.WechatSendMsg;

   import testWeb.bean.WechatSendMsgBody;

   import testWeb.bean.WechatSendMsgData;

    

   public class TestWechatMsg {

    

   private static String TEST_APPID = "wxa1d64a418271a654";

   private static String TEST_APPSECRET = "bd814671571d837e287ee10887a77fc1";

   private static String WECHART_URL_TOKEN = "https://api.weixin.qq.com/cgi-bin/token";

   private static String WECHART_URL_SEND_TEMPLATE_MSG = "https://api.weixin.qq.com/cgi-bin/message/template/send";

   private static String OPEN_ID_1 = "oDfGiwEHCvsUQDl-nytTEzLVf9rA";

   private static String TEMPLATE_ID = "N6rCGkAPQa6W_0l32lVBtLwhhXEDfmA5oDX6kPHU_bg";

   private static String TOP_COLOR = "#FF0000";

   private static String GO_URL = "http://weixin.qq.com/download";

    

   public static void main(String[] args) {

   String tokenStr = getAccessToken();

   Map<String, String> dataMap = new HashMap<String, String>();

   dataMap.put("barcode", "000000211");

   dataMap.put("status", "已发车");

   dataMap.put("payment", "500元");

   dataMap.put("goodspaystatus", "已支付");

   dataMap.put("postage", "50元");

   dataMap.put("paystatus", "已支付");

   String result = sendWechatTempMsg(tokenStr, OPEN_ID_1, GO_URL, dataMap);

   System.out.println(result);

   }

    

   public static String doPostRequest(String urlStr, String data) {

   StringBuffer answer = new StringBuffer();

   // Build parameter string

   try {

   // Send the request

   URL url = new URL(urlStr);

   URLConnection conn = url.openConnection();

   conn.setDoOutput(true);

   OutputStreamWriter writer = new OutputStreamWriter(conn.getOutputStream());

   // write parameters

   writer.write(data);

   writer.flush();

   // Get the response

   BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));

   String line;

   while ((line = reader.readLine()) != null) {

   answer.append(line);

   }

   writer.close();

   reader.close();

   } catch (MalformedURLException ex) {

   ex.printStackTrace();

   } catch (IOException ex) {

   ex.printStackTrace();

   }

   return answer.toString();

   }

    

   public static String doGetRequest(String urlStr, String data) {

   String res = "";

   // Build parameter string

   try {

   BufferedReader rd = null;

   // Send the request

   URL url = new URL(urlStr + "?" + data);

   HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();

   urlConnection.connect();

   rd = new BufferedReader(new InputStreamReader(urlConnection.getInputStream(), "UTF-8"));

   /*

    * while (rd.read() != -1) { res = rd.readLine();

    * //res=URLDecoder.decode(res,"UTF-8"); }

    */

   String line;

   while ((line = rd.readLine()) != null) {

   res += line;

   }

   rd.close();

   System.out.println(res);

   return res;

   } catch (MalformedURLException ex) {

   ex.printStackTrace();

   } catch (IOException ex) {

   ex.printStackTrace();

   }

    

   return res;

   }

    

   public static String getAccessToken() {

   String data = "grant_type=client_credential" + "&appid=" + TEST_APPID + "&secret=" + TEST_APPSECRET;

   String res = doGetRequest(WECHART_URL_TOKEN, data);

   Map<String, Object> dataMap = new HashMap<String, Object>();

   dataMap = JSON.parseObject(res);

   return (String) dataMap.get("access_token");

   }

    

   public static String sendWechatTempMsg(String accessToken, String openid, String url, Map<String, String> dataMap) {

   String result = null;

   String data = "access_token=" + accessToken;

   String sendMsg = getSendMsg(openid, url, dataMap);

   result = doPostRequest(WECHART_URL_SEND_TEMPLATE_MSG + "?" + data, sendMsg);

   return result;

   }

    

   public static String getSendMsg(String openid, String url, Map<String, String> dataMap) {

   WechatSendMsgBody msgBody = new WechatSendMsgBody();

   msgBody.setTouser(openid);

   msgBody.setTemplate_id(TEMPLATE_ID);

   msgBody.setTopcolor(TOP_COLOR);

   msgBody.setUrl(url);

   WechatSendMsgData data = new WechatSendMsgData();

   WechatSendMsg barcode = new WechatSendMsg();

   barcode.setValue(dataMap.get("barcode"));

   WechatSendMsg status = new WechatSendMsg();

   status.setValue(dataMap.get("status"));

   WechatSendMsg payment = new WechatSendMsg();

   payment.setValue(dataMap.get("payment"));

   WechatSendMsg goodspaystatus = new WechatSendMsg();

   goodspaystatus.setValue(dataMap.get("goodspaystatus"));

   WechatSendMsg postage = new WechatSendMsg();

   postage.setValue(dataMap.get("postage"));

   WechatSendMsg paystatus = new WechatSendMsg();

   paystatus.setValue(dataMap.get("paystatus"));

   data.setBarcode(barcode);

   data.setGoodspaystatus(goodspaystatus);

   data.setPayment(payment);

   data.setPaystatus(paystatus);

   data.setPostage(postage);

   data.setStatus(status);

   msgBody.setData(data);

   return JSON.toJSONString(msgBody);

   }

    

   }

    

2. 封装对象后转换成json传递给微信平台发信息

    WechatSendMsgBody.java  消息体

package testWeb.bean;

import java.io.Serializable;
import java.util.List;

public class WechatSendMsgBody implements Serializable {

 /**
  *
  */
 private static final long serialVersionUID = 1L;
 //发送对象的
 private String touser;
 //消息模版id
 private String template_id;
 //消息链接url
 private String url;
 //标题颜色
 private String topcolor;
 //内容数据
 private WechatSendMsgData data;
 public String getTouser() {
  return touser;
 }
 public void setTouser(String touser) {
  this.touser = touser;
 }
 public String getTemplate_id() {
  return template_id;
 }
 public void setTemplate_id(String template_id) {
  this.template_id = template_id;
 }
 public String getUrl() {
  return url;
 }
 public void setUrl(String url) {
  this.url = url;
 }
 public String getTopcolor() {
  return topcolor;
 }
 public void setTopcolor(String topcolor) {
  this.topcolor = topcolor;
 }
 public WechatSendMsgData getData() {
  return data;
 }
 public void setData(WechatSendMsgData data) {
  this.data = data;
 }
}

WechatSendMsgData.java   消息数据

package testWeb.bean;

import java.io.Serializable;

public class WechatSendMsgData implements Serializable {

 /**
  *
  */
 private static final long serialVersionUID = 1L;
 
 private WechatSendMsg barcode;
 private WechatSendMsg status;
 private WechatSendMsg payment;
 private WechatSendMsg goodspaystatus;
 private WechatSendMsg postage;
 private WechatSendMsg paystatus;
 
 
 public WechatSendMsg getBarcode() {
  return barcode;
 }
 public void setBarcode(WechatSendMsg barcode) {
  this.barcode = barcode;
 }
 public WechatSendMsg getStatus() {
  return status;
 }
 public void setStatus(WechatSendMsg status) {
  this.status = status;
 }
 public WechatSendMsg getPayment() {
  return payment;
 }
 public void setPayment(WechatSendMsg payment) {
  this.payment = payment;
 }
 public WechatSendMsg getGoodspaystatus() {
  return goodspaystatus;
 }
 public void setGoodspaystatus(WechatSendMsg goodspaystatus) {
  this.goodspaystatus = goodspaystatus;
 }
 public WechatSendMsg getPostage() {
  return postage;
 }
 public void setPostage(WechatSendMsg postage) {
  this.postage = postage;
 }
 public WechatSendMsg getPaystatus() {
  return paystatus;
 }
 public void setPaystatus(WechatSendMsg paystatus) {
  this.paystatus = paystatus;
 }
}

WechatSendMsg.java 数据内容颜色

package testWeb.bean;

import java.io.Serializable;

public class WechatSendMsg implements Serializable {

 /**
  *
  */
 private static final long serialVersionUID = 1L;
 private String value;
 private String color="#173177";
 public String getValue() {
  return value;
 }
 public void setValue(String value) {
  this.value = value;
 }
 public String getColor() {
  return color;
 }
 public void setColor(String color) {
  this.color = color;
 } 
}

总结微信消息推送主要还是通过微信api进行get或者Post请求进行消息好发送类似于短信发送

正式公众号openid获得方式请查看微信官方开发文档
