java快速构建飞书API消息推送、消息加急等功能

import feign.Headers;
import feign.Param;
import feign.RequestLine;
 
public interface FeishuApi {
 
    @RequestLine("POST /message/v4/send")
    @Headers("Content-Type: application/json")
    void sendMessage(@Param("body") String body);
 
    @RequestLine("POST /message/v4/batch_send")
    @Headers("Content-Type: application/json")
    void batchSendMessage(@Param("body") String body);
 
    @RequestLine("POST /message/v4/update")
    @Headers("Content-Type: application/json")
    void updateMessage(@Param("body") String body);
 
    @RequestLine("POST /bot/v4/app/{{app_id}}/message/send")
    @Headers("Content-Type: application/json")
    void sendMessageToBot(@Param("app_id") String appId, @Param("body") String body);
 
    // 以下是构建请求体的辅助方法
    static String buildSendMessageBody(String receiverId, String content, boolean urgent) {
        StringBuilder body = new StringBuilder();
        body.append("{\"receiver_id\":\"").append(receiverId).append("\",");
        body.append("\"content\":\"").append(content).append("\",");
        body.append("\"msg_type\":\"text\",");
        body.append("\"extra\":");
        if (urgent) {
            body.append("{\"urgency\":\"").append("urgent").append("\"}");
        } else {
            body.append("null");
        }
        body.append("}");
        return body.toString();
    }
}

这个代码示例展示了如何使用Feign客户端快速构建飞书（Feishu）API的消息发送功能。其中，buildSendMessageBody方法用于根据接收者ID、消息内容和是否加急构建请求体。在实际使用时，你需要提供正确的接收者ID、消息内容，并根据业务需求设置是否加急。
