通过微信公众号给女朋友推送消息

先看下效果图
在这里插入图片描述

准备工作
1、首先去微信公众平台注册成为测试号，点这里
在这里插入图片描述

然后再添加一个模板
在这里插入图片描述

![在这里插入图片描述](https://img-blog.csdnimg.cn/875c3ac58c014834b33e268cf239eda2.png
模板里的json字符串示例如下

{{date.DATA}} {{remark.DATA}} 所在城市：{{city.DATA}} 今日天气：{{weather.DATA}} 气温变化：{{min_temperature.DATA}}~{{max_temperature.DATA}} 今日建议：{{tips.DATA}} 今天是我们恋爱的第{{love_days.DATA}}天 距离婷宝贝生日还有{{girl_birthday.DATA}}天 距离你家康先生生日还有{{boy_birthday.DATA}}天 {{rainbow.DATA}}

天气和情话我调用的是天行数据管理系统的，他们有免费的额度，够用。
最后就再新建一个springboot项目就好了。

代码实现部分
微信配置代码

package cc.mrbird.febs.system.until;import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;@Component
public class WeChatConfigure {public static String Access_URL = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid={0}&secret={1}";public static String Send_URL = "https://api.weixin.qq.com/cgi-bin/message/template/send?access_token={0}";public static String App_ID;@Value("${WeChat.AppID}")public void setAppID(String AppID) {App_ID = AppID;}public static String App_Secret;@Value("${WeChat.AppSecret}")public void setAppSecret(String AppSecret) {App_Secret = AppSecret;}public static String Open_ID;@Value("${WeChat.OpenID}")public void setOpenID(String OpenID) {Open_ID = OpenID;}public static String Template_ID;@Value("${WeChat.TemplateID}")public void setTemplateID(String TemplateID) {Template_ID = TemplateID;}public static String Top_Color;@Value("${WeChat.TopColor}")public void setTopColor(String TopColor) {Top_Color = TopColor;}public static String Weather_API;@Value("${WeChat.WeatherAPI}")public void setWeatherAPI(String WeatherAPI) {Weather_API = WeatherAPI;}public static String Rainbow_API;@Value("${WeChat.RainbowAPI}")public void setRainbowAPI(String RainbowAPI) {Rainbow_API = RainbowAPI;}public static String Boy_Birthday;@Value("${WeChat.BoyBirthday}")public void setBoyBirthday(String BoyBirthday) {Boy_Birthday = BoyBirthday;}public static String Girl_Birthday;@Value("${WeChat.GirlBirthday}")public void setGirlBirthday(String GirlBirthday) {Girl_Birthday = GirlBirthday;}public static String Love_Day;@Value("${WeChat.LoveDay}")public void setLoveDay(String LoveDay) {Love_Day = LoveDay;}
}

具体的值写在yml配置文件里的，示例如下
