1.如何在企业微信群中创建一个机器人


  

2.企业微信机器人发送群消息

2.1相关的api文档

群机器人配置说明 - 接口文档 - 企业微信开发者中心

2.2java需要引入的jar包

      通过文档,可以知道,只是调用一个http请求。我这边使用的是httpclient进行调用。需要添加的依赖有:

<dependency>
            <groupId>org.apache.httpcomponents</groupId>
            <artifactId>httpclient</artifactId>
            <version>4.5.13</version>
        </dependency>
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-api</artifactId>
            <version>1.7.32</version>
        </dependency>

2.4遇到的问题

      当我想将发送的消息抽成一个模板,放到nacos配置文件的时候。遇到了一个问题:yml转行问题。

@Configuration
@RefreshScope
@Data
@ConfigurationProperties(prefix = "activity")
public class ActivityCreateConfig {

    private String wxGroupKey;
    private String createActivityTemplate;

    private String approveSkuTemplate;

    private String saveLinksTemplate;

    private String importSkuTemplate;

    private List<TenantKeyMap> tenantKeyMapping;

}
@Data
public class TenantKeyMap {
    private Long tenantId;
    private String key;
}

对应的template配置如下:

activity:
  wxGroupKey: 9d1efcff-c62e-4c93-bb7c-21d947c53cbc
  createActivityTemplate: "有新的活动创建,请即使处理。\n
  >团长名称:<font color='warning'>%s</font>\n
  >活动:<font color='warning'>%s</font>\n
  >创建时间:<font color='#666666'>%s</font>\n
  >报名时间:<font color='#666666'>%s</font>\n
  >推广时间:<font color='#666666'>%s</font>\n"
  saveLinksTemplate: "抖音活动已创建。\n
  >活动名称:<font color='warning'>%s</font>\n
  >报名链接:<font color='warning'>[报名链接](%s)</font>\n"
  importSkuTemplate: "抖音活动商品已更新。\n
  >活动名称:<font color='warning'>%s</font>\n
  >待审核:<font color='info'>%s</font>\n
  >已审核:<font color='info'>%s</font>\n"
  approveSkuTemplate: "有新的商品审核通过,请及时处理\n
  >团长名称:<font color='warning'>%s</font>\n
  >活动:<font color='warning'>%s</font>\n
  >审批时间:<font color='warning'>%s</font>\n"
  tenantKeyMapping:
  - tenantId: 100240
    key: 9d1efcff-c62e-4c93-bb7c-21d947c53cbc
  - tenantId: 100240
    key: 9d1efcff-c62e-4c93-bb7c-21d947c53cbc
