微信公众号初次开发其他操作项目搭建mavenapplication.ymlyml参数配置微信客户端配置搭建完成实现业务模板消息推送准备工作模板消息填写要求图文消息填写要求推送模板消息推送模板消息结果——效果推送图文消息推送图文消息工具类问题和结果获取关注的用户openId既然有了openId集合和要发送的消息怎么群发

其他操作

书接上文：微信测试号申请步骤和调试. 书接下文：后台获取授权用户的openId.

在这里插入图片描述链接: 申请测试模板.

模板消息填写要求

first.DATA 跟上.DATA说明是数据

人员：{{first.DATA}} 地址：{{keyword1.DATA}} 区域：{{keyword2.DATA}} 告警类型：{{remark1.DATA}} 时间：{{remark2.DATA}} 图文消息填写要求推送模板消息

这里使用微信提供的serviceApi 链接: WxMpService.

"成功" : "失败"); return msgId != null; } } 推送模板消息结果——效果

在这里插入图片描述点击详情会进入百度

推送图文消息 /** * 获取token * @return */ public String getAccessToken() throws WxErrorException { String accessToken = wxMpService.getAccessToken(); return accessToken; } @ApiOperation(value = "", notes = "") @ResponseBody @RequestMapping(value = "/findwx", method = RequestMethod.POST) public void SendQYMessageimg(@RequestParam("id") String id) throws WxErrorException { String Url = "http://www.baidu.com"; String mp = getAccessToken(); String strurl = "https://api.weixin.qq.com/cgi-bin/message/custom/send?access_token=" + mp; try { //图片地址 String PicUrl = "https://img-blog.csdn.net/20160907155302548"; String responeJsonStr = "{"; //用户openId responeJsonStr += "\"touser\": \"" + "用户openId" + "\","; responeJsonStr += "\"msgtype\": \"news\","; responeJsonStr += "\"agentid\": \"wxd4aff8****\","; responeJsonStr += "\"news\": {"; responeJsonStr += "\"articles\": [{"; responeJsonStr += " \"title\": \"" + "震惊外国一小伙竟然做出... ..." + "\","; responeJsonStr += " \"description\": \" " + "今日一美国男子在家中，竟然做出... ..." + "\","; responeJsonStr += " \"url\": \"" + Url + "\","; responeJsonStr += " \"picurl\": \"" + PicUrl + "\""; responeJsonStr += "}]"; responeJsonStr += "},"; responeJsonStr += "\"safe\":\"0\""; responeJsonStr += "}"; xstream.connectWeiXinInterface(strurl, responeJsonStr); } catch (Exception e) { e.printStackTrace(); } } 推送图文消息工具类 import java.io.InputStream; import java.io.OutputStream; import java.net.HttpURLConnection; import java.net.URL; public class xstream { public static void connectWeiXinInterface(String action,String json){ URL url; try { url = new URL(action); HttpURLConnection http = (HttpURLConnection) url.openConnection(); http.setRequestMethod("POST"); http.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); http.setDoOutput(true); http.setDoInput(true); System.setProperty("sun.net.client.defaultConnectTimeout", "30000");// 连接超时30秒 System.setProperty("sun.net.client.defaultReadTimeout", "30000"); // 读取超时30秒 http.connect(); OutputStream os = http.getOutputStream(); os.write(json.getBytes("UTF-8"));// 传入参数 InputStream is = http.getInputStream(); int size = is.available(); byte[] jsonBytes = new byte[size]; is.read(jsonBytes); String result = new String(jsonBytes, "UTF-8"); System.out.println("请求返回结果:"+result); os.flush(); os.close(); } catch (Exception e) { e.printStackTrace(); } } } 问题和结果

要用户先发送一条消息给公众号，你才能发送成功在这里插入图片描述点击消息会进入百度

获取关注的用户openId /** * 获得关注公众号所有openid * @return * @throws WxErrorException */ @Override public List getUserList() throws WxErrorException { WxMpUserList wxMpUserList = wxMpService.getUserService().userList(null); List openids = wxMpUserList.getOpenids(); return openids; } 既然有了openId集合和要发送的消息怎么群发

微信并没有提供群发接口–就在自己代码中迭代openId集合去循环发送
