微信公众号消息推送-模板消息发送
先注册一个微信公众号;或者申请接口测试号来进行开发;
接口测试号申请链接:

这里先介绍测试号的开发;
点击链接进入页面,会看到y一个二维码,用微信扫描后就会分配给你一个微信公众测试账号;
然后找到如下这个位置,点击“新增测试模板”按钮,填写
下面是相关代码;
@Test public void sendTemplate(){ postTemplateMsg("appid","appSecret", "openId");//这里替换成你自己的信息 } public String sendTemplateMessage(String openId){ TemplateMsg tm=new TemplateMsg(); tm.setTouser(openId); tm.setTemplate_id("模板Id"); tm.setUrl("https://wwww.baidu.com"); //about data start Map<String,Object> m = new HashMap<String,Object>(); TemplateData first = new TemplateData(); first.setColor("#000000"); first.setValue("您好,您有一个流程待办需要处理:"); m.put("first", first); TemplateData keyword1 = new TemplateData(); keyword1.setColor("#000000"); keyword1.setValue("11111111111111"); m.put("keyword1", keyword1); TemplateData keyword2 = new TemplateData(); keyword2.setColor("#000000"); keyword2.setValue("爱你一万年"); m.put("keyword2", keyword2); TemplateData keyword3 = new TemplateData(); keyword3.setColor("#000000"); keyword3.setValue("2018.04.27 09:51:30"); m.put("keyword3", keyword3); TemplateData keyword4 = new TemplateData(); keyword4.setColor("#000000"); keyword4.setValue("不够"); m.put("keyword4", keyword4); TemplateData remark = new TemplateData(); remark.setColor("#000000"); remark.setValue("再加一万年"); m.put("remark", remark); //about data end tm.setData(m); String jsonString = JSONObject.fromObject(tm).toString(); System.out.println("jsonString:"+jsonString); return jsonString; } /** * 发送模板消息 * appId 公众账号的唯一标识 * appSecret 公众账号的密钥 * openId 用户标识 */ public void postTemplateMsg(String appId, String appSecret, String openId){ Token token = CommonUtil.getToken(appId, appSecret); String access_token = token.getAccessToken(); String requestUrl = "https://api.weixin.qq.com/cgi-bin/message/template/send?access_token="+access_token; System.out.println("requestUrl:"+requestUrl); String jsonString = sendTemplateMessage(openId); JSONObject jsonObject = CommonUtil.httpsRequest(requestUrl, "POST", jsonString); System.out.println("jsonObject="+jsonObject); if (null != jsonObject) { int errorCode = jsonObject.getInt("errcode"); if (0 == errorCode) { System.out.println("模板消息发送成功!"); } else { String errorMsg = jsonObject.getString("errmsg"); System.out.println("模板消息发送失败,错误码是:"+errorCode+",错误信息是:"+errorMsg); } } }
