搭建完成 实现业务
模板消息推送
准备工作
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

推送图文消息
/**

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 += " \"picurl\": \"" + PicUrl + "\"";
responeJsonStr += "}]";
responeJsonStr += "},";
responeJsonStr += "\"safe\":\"0\"";
responeJsonStr += "}";
xstream.connectWeiXinInterface(strurl, responeJsonStr);
} 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
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<String> getUserList() throws WxErrorException {
WxMpUserList wxMpUserList = wxMpService.getUserService().userList(null);
List<String> 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
