一、微信公众平台小程序开通消息订阅并设置模板
这边的模板id和详细内容后续前后端需要使用
二、uniapp前端
需要是一个button触发
js：文章来源：https://www.toymoban.com/news/detail-659679.html
wx.getSetting({
success(res){
console.log(res)
if(res.authSetting['scope.subscribeMessage']){
// 业务逻辑
}else{
uni.requestSubscribeMessage({
tmplIds: [_config.TEMPLATE_ID],
success (res) {
console.log("订阅成功！")
// 业务逻辑
},
fail(res) {
// 即使用户拒绝订阅也要继续原来的业务逻辑
}
})
}
}
})
三、java后端
@Component
@Slf4j
public class WxAccessTokenUtil {
@Value("${WX_APPID}")
String APP_ID;
@Value("${WX_SECREAT}")
String SECREAT;
@Value("${WX_TEMPLATE_ID}")
String TEMPLATE_ID;
public String getWxAccessToken(){
String res = HttpClient.doGet("https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid="+APP_ID+"&secret="+SECREAT);
JSONObject jsonObject = JSON.parseObject(res);
return jsonObject.getString("access_token");
}
public void sendReservationSubscribeMsg(String touser,String id,String apparatusName,String state){
String token = getWxAccessToken();
JSONObject jsonObject2 = new JSONObject();
jsonObject2.put("access_token",token);
jsonObject2.put("touser",touser);
jsonObject2.put("template_id",TEMPLATE_ID);
jsonObject2.put("page","/pages/appointment_detail/appointment_detail?id="+id);
JSONObject data = new JSONObject();
JSONObject thing2 = new JSONObject();
thing2.put("value",apparatusName);
data.put("thing2",thing2);
JSONObject phrase3 = new JSONObject();
phrase3.put("value",state);
data.put("phrase3",phrase3);
jsonObject2.put("data",data);
String res = HttpClient.doPost("https://api.weixin.qq.com/cgi-bin/message/subscribe/send?access_token="+token,jsonObject2.toString());
log.warn("微信小程序订阅消息：{}",res);
}
}
其中thing2、phrase3是模板的字段名，根据自己模板去修改即可文章来源地址https://www.toymoban.com/news/detail-659679.html
HttpClient.java
public class HttpClient {
public static void main(String[] args) {
String APP_ID = "xxx";
String SECREAT = "xxx";
String res = HttpClient.doGet("https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid="+APP_ID+"&secret="+SECREAT);
com.alibaba.fastjson.JSONObject jsonObject = JSON.parseObject(res);
String token = jsonObject.getString("access_token");
JSONObject jsonObject2 = new JSONObject();
jsonObject2.put("access_token",token);
jsonObject2.put("touser","xxxxx");
jsonObject2.put("template_id","xxxx");
jsonObject2.put("page","/pages/tabbar/mine/mine");
JSONObject data = new JSONObject();
JSONObject phrase1 = new JSONObject();
phrase1.put("value","待审核");
data.put("phrase1",phrase1);
JSONObject thing2 = new JSONObject();
thing2.put("value","已成功提交预约申请，请耐心等待审核。");
data.put("thing2",thing2);
jsonObject2.put("data",data);
jsonObject2.put("miniprogram_state","trial");
System.out.println(HttpClient.doPost("https://api.weixin.qq.com/cgi-bin/message/subscribe/send?access_token="+token,jsonObject2.toString()));
