企业微信消息推送

基本概念：https://developer.work.weixin.qq.com/document/path/90665
推送消息：https://developer.work.weixin.qq.com/document/path/90236#10112
获取access_token： https://developer.work.weixin.qq.com/document/path/91039

这个看着是a标签，好像是html,其实并不是通用的html,而是企业微信在text类型消息 里面做的特殊扩展,
只能像他官方例子那样写，，，如果将 双引号 变成 单引号，，消息不回被推送过去，，如果加了 style设置了样式，，a标签就不会解析，，会将a标签也显示在文本中，这是企业微信消息的渲染规则

1. 获取acces_token ，并缓存到redis中
2. 发送消息

@Component
@ConfigurationProperties(prefix = "wechat")
public class WechatConfig {private String corpId;private String secret;private Integer agentId;// h5 oauth2授权地址  http://oauth2.water-kid.xyz/social-login  http://localhost:8080/#/pages/mine/oauth2-login/oauth2-loginprivate String oauth2RedirectUrl;public String getOauth2RedirectUrl() {return oauth2RedirectUrl;}public void setOauth2RedirectUrl(String oauth2RedirectUrl) {this.oauth2RedirectUrl = oauth2RedirectUrl;}// Getters and Setterspublic String getCorpId() {return corpId;}public void setCorpId(String corpId) {this.corpId = corpId;}public String getSecret() {return secret;}public void setSecret(String secret) {this.secret = secret;}public Integer getAgentId() {return agentId;}public void setAgentId(Integer agentId) {this.agentId = agentId;}
}
