Springboot微信公众号模板消息推送

1.Controller层代码

package com.example.tuisong.controller;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.*;
import org.springframework.web.client.RestTemplate;

@RestController
@RequestMapping("/api")
public class WeChatConller {
    @Value("${wechat.appId}")
    private String appId;

    @Value("${wechat.appSecret}")
    private String appSecret;

    @Value("${wechat.templateMessageUrl}")
    private String templateMessageUrl;

    @PostMapping("/template-message")
    public String sendTemplateMessage(@RequestBody String data) {
        // 1. 获取access_token
        String accessToken = getAccessToken();

        // 2. 构造模板消息
        String templateMessage = buildTemplateMessage(data);

        // 3. 发送模板消息
        String url = templateMessageUrl + "?access_token=" + accessToken;
        RestTemplate restTemplate = new RestTemplate();
        String response = restTemplate.postForObject(url, templateMessage, String.class);
        return response;
    }

    private String getAccessToken() {
        String url = templateMessageUrl + "&appid=" + appId + "&secret=" + appSecret;
        RestTemplate restTemplate = new RestTemplate();
        String response = restTemplate.getForObject(url, String.class);
        return response;
    }

    private String buildTemplateMessage(String data) {
        // 根据传入的数据构造模板消息
        // 可以使用JSON转换工具，如Jackson或Gson
        return data;
    }

}

2.配置文件application.properties

3.获取access-token
GET:https请求方式: GET https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=APPID&secret=APPSECRET

发送模板消息http请求方式: POST https://api.weixin.qq.com/cgi-bin/message/template/send?access_token=ACCESS_TOKEN

touser:是openID
template_id是模板id
