去微信公众平台注册一个开发测试账号

个人开发，我们可以去微信公众号平台注册个测试账户点我直达，微信扫码登录，会给我们一个免费的：appID、appsecret，微信扫码关注公众号，会显示关注测试公众号的用户列表。全局错误码：点我直达

测试

关注测试公众号，创建模板，并发送指定模板内容

替换版本内容

在微信公众平台创建模板

语法：{{变量名.DATA}}
姓名：{{user_name.DATA}}
性别：{{sex.DATA}}
手机号：{{phone.DATA}}
邮箱：{{email.DATA}}

测试获取微信Access token接口

package com.laoxu.demo.bootstrapcurd.controller;import com.laoxu.demo.bootstrapcurd.service.AccessTokenService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;

@RestController
@RequestMapping("/accessToken")
public class AccessTokenController {@Autowiredprivate AccessTokenService accessTokenService;/*** 获取微信Access token接口* @return* @throws Exception*/@RequestMappingpublic String getAccessToken() throws Exception {return accessTokenService.getAccessToken();}}

access_token：接口调用凭证

expires_in：过期时间

{"access_token":"60_A8T9k5Plmyxkc6PG5dHYXhRsBvb9Ce1HN67a9awvHRWsS7nxWwKWuR6kU1G_yyINRJLPiEoluHKoGKqWvwls2wbz32tvxr4UdW2f_bqX4camjhuDXCkL-IlYZbukpc9zjaBjHACElJTokqflJVMjABAYKB","expires_in":7200}

微信公众平台常量类

public class WeCharConstant {public static final String CREATE_TIME = "CreateTime";public static final String CONTENT = "Content";public static final String FROM_USER_NAME = "FromUserName";public static final String TO_USER_NAME = "ToUserName";public static final String MSG_TYPE = "MsgType";public static final String MSG_ID = "MsgId";/*** 创建菜单URL*/public static final String CREATE_MENU_URL = "https://api.weixin.qq.com/cgi-bin/menu/create?access_token=ACCESS_TOKEN";/*** 删除菜单URL*/public static final String DELETE_MENU_URL = "https://api.weixin.qq.com/cgi-bin/menu/delete?access_token=ACCESS_TOKEN";/*** 模版服务相关-设置所属行业*/public static final String SET_INDUSTRY = "https://api.weixin.qq.com/cgi-bin/template/api_set_industry?access_token=ACCESS_TOKEN";/*** 获取所属行业信息*/public static final String GET_INDUSTRY = "https://api.weixin.qq.com/cgi-bin/template/get_industry?access_token=ACCESS_TOKEN";/*** 获取所有模版信息*/public static final String GET_ALL_PRIVATE_TEMPLATE = "https://api.weixin.qq.com/cgi-bin/template/get_all_private_template?access_token=ACCESS_TOKEN";/*** 发送模版消息*/public static final String TEMPLATE_SEND = "https://api.weixin.qq.com/cgi-bin/message/template/send?access_token=ACCESS_TOKEN";/*** 获取OAUTH认证的access_token*/public static final String OAUTH_GET_AT = "https://api.weixin.qq.com/sns/oauth2/access_token?appid=APPID&secret=SECRET&code=CODE&grant_type=authorization_code";/*** 获取用户基本信息*/public static final String OAUTH_USER_INFO = "https://api.weixin.qq.com/sns/userinfo?access_token=ACCESS_TOKEN&openid=OPENID&lang=zh_CN";/*** 引导链接*/public static final String OAUTH2_AUTHORIZE = "https://open.weixin.qq.com/connect/oauth2/authorize?appid=APPID&redirect_uri=REDIRECT_URI&response_type=code&scope=SCOPE&state=STATE#wechat_redirect";}

接下来就是微信测试模板消息推送

package com.laoxu.demo.bootstrapcurd.controller;import com.laoxu.demo.bootstrapcurd.service.message.TemplateService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;import java.io.IOException;/*** @author: wangxiaobo* @create: 2022-08-31 21:03* 模板微信推送消息处理接口**/
@RestController
@RequestMapping("/v1/weChar")
public class TemplateController {@Autowiredprivate TemplateService templateService;/*** 设置行业信息* @param body 请求对象* @return* @throws IOException*/@RequestMapping("/setIndustry")public String setIndustry(@RequestBody String body) throws IOException {return templateService.setIndustry(body);}/*** 获取行业信息* @return* @throws IOException*/@RequestMapping("/getIndustry")public String setIndustry() throws IOException {return templateService.getIndustry();}/*** 获取微信公众平台全部模版消息* @return* @throws IOException*/@RequestMapping("/getTemplateList")public String getTemplateList() throws IOException {return templateService.getTemplateList();}/*** 发送模版消息* @param body* @return* @throws IOException*/@RequestMapping("/send")public String send(@RequestBody String body) throws IOException {return templateService.send(body);}}

测试发送模板接口之前首先要获取模板ID：template_id

测试发送模板接口

touser：填你的openId就是扫测试号的微信号

template_id：模板ID

url：要跳转的链接

{"touser":"owfI16osHtU_UV277BYfm0EwPJPo","template_id":"yuaFG-DmpAZiCM22aBQ9we3Luk8g6Xv400qQXcfn84g","url":"http://www.baidu.com",  "data":{"first": {"value":"中国移动通信缴费通知","color":"#173177"},"keyword1":{"value":"填写手机号"},"keyword2": {"value":"-60元","color":"#FF0000"},"keyword3": {"value":"60元","color":"#173177"},"keyword4": {"value":"2022年8月31日","color":"#173177"},"keyword5": {"value":"666666666","color":"#173177"},"remark":{"value":"欢迎使用中国移动通信","color":"#173177"}}}
