5.25 飞书自建应用创建机器人 其三 创建应用

接上文
1.点
2.订阅方式：将回调发送至服务器：填写地址（一般与事件填的的那个地址相同）：
（注：填写 URL 以使订阅生效。填写后，飞书服务器会向其发送一个 HTTP POST 以验证地址有效期，请求格式为 JSON ，带 CHALLENGE 参数。应用接收此请求后，需要解析出 CHALLENGE 值，并在 1 秒内回复 CHALLENGE 值）
3.后端配置：
1.maven坐标：

oapi-sdk-servlet-ext
com.larksuite.oapi
1.0.0-rc3


oapi-sdk
com.larksuite.oapi



2.扩展包注入ioc
@Bean
public ServletAdapter getServletAdapter() {
return new ServletAdapter();

3.新版卡片回调：
import com.lark.oapi.core.utils.Jsons;
import com.lark.oapi.event.EventDispatcher;
import com.lark.oapi.event.cardcallback.P2CardActionTriggerHandler;
import com.lark.oapi.event.cardcallback.P2URLPreviewGetHandler;
import com.lark.oapi.event.cardcallback.model.*;
import com.lark.oapi.sdk.servlet.ext.ServletAdapter;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

@RestController
public class EventController {

//1. 注册消息处理器
private final EventDispatcher EVENT_DISPATCHER = EventDispatcher.newBuilder("", "")
.onP2CardActionTrigger(new P2CardActionTriggerHandler() {
// 监听「卡片回传交互 card.action.trigger」
@Override
public P2CardActionTriggerResponse handle(P2CardActionTrigger event) throws Exception {
System.out.printf("[ P2CardActionTrigger access ], data: %s\n", Jsons.DEFAULT.toJson(event.getEvent()));
P2CardActionTriggerResponse resp = new P2CardActionTriggerResponse();
CallBackToast toast = new CallBackToast();
toast.setType("info");
toast.setContent("卡片交互成功 from Java SDk");
resp.setToast(toast);
return resp;
}
})
// 监听「拉取链接预览数据 url.preview.get」
.onP2URLPreviewGet(new P2URLPreviewGetHandler() {
@Override
public P2URLPreviewGetResponse handle(P2URLPreviewGet event) throws Exception {
System.out.printf("[ P2URLPreviewGet access ], data: %s\n", Jsons.DEFAULT.toJson(event.getEvent()));
P2URLPreviewGetResponse resp = new P2URLPreviewGetResponse();
URLPreviewGetInline inline = new URLPreviewGetInline();
inline.setTitle("链接预览测试fromJavaSDK");
resp.setInline(inline);
return resp;
}
})
.build();

//2. 注入 ServletAdapter 实例
@Autowired
private ServletAdapter servletAdapter;

//3. 创建路由处理器
@RequestMapping("/webhook/event")
public void event(HttpServletRequest request, HttpServletResponse response)
throws Throwable {
//3.1 回调扩展包提供的事件回调处理器
servletAdapter.handleEvent(request, response, EVENT_DISPATCHER);
}
}
