SpringBoot小程序推送信息

李日兴lrx 人气:0

1.小程序推送信息列如我们去餐厅等位有预约提醒,剩余桌数

首先申请一个小程序,微信开放平台:小程序

2.申请小程序信息,申请信息模板

appid

 AppSecret

3.根据开发文档开发

subscribeMessage.send | 微信开放文档

4.代码如下:

引入依赖

 <dependency>
        <groupId>org.apache.httpcomponents</groupId>
        <artifactId>httpclient</artifactId>
        <version>4.5.2</version>
    </dependency>

先准备一个HTTP工具类Z

import org.apache.http.client.methods.CloseableHttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.conn.ssl.NoopHostnameVerifier;
import org.apache.http.conn.ssl.SSLConnectionSocketFactory;
import org.apache.http.conn.ssl.TrustSelfSignedStrategy;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;
import org.apache.http.ssl.SSLContexts;
import org.apache.http.util.EntityUtils;
 
import java.io.IOException;
