实现apk上传蒲公英后自动发送钉钉通知

Webhook是一个API概念，并且变得越来越流行。我们能用事件描述的事物越多，webhook的作用范围也就越大。Webhook作为一个轻量的事件处理应用，正变得越来越有用。

准确的说webhoo是一种web回调或者http的push API，是向APP或者其他应用提供实时信息的一种方式。Webhook在数据产生时立即发送数据，也就是你能实时收到数据。这一种不同于典型的API，需要用了实时性需要足够快的轮询。这无论是对生产还是对消费者都是高效的，唯一的缺点是初始建立困难。

Webhook有时也被称为反向API，因为他提供了API规则，你需要设计要使用的API。Webhook将向你的应用发起http请求，典型的是post请求，应用程序由请求驱动。

在Android开发中会经常提交apk给测试人员进行测试,通常的做法是将构建完成的包上传至蒲公英,测试人员直接扫码下载并安装apk包从而进行测试.一般我们会将构建及发布过程自动化,可参考:

文章中实现了apk上传蒲公英后邮件通知,可是实际中,大家对邮件的关注远远没有对IM消息的关注度高,所以接下来本文将说明,实现上传apk后自动发送钉钉消息,将更新内容,apk版本号等信息通知到测试人员

环境准备

首先环境搭建是IntelliJ+SpringMVC+Gradle构建的,如有疑问的同学可参考IDEA+Gradle创建MyBatis+SpringMVC项目,项目中主要是对接口数据的调整及转发,实际上未用到MyBatis,可自行进行去除🙄.

模型建立

对照蒲公英doc、钉钉doc分别建立Java Bean.

PgyerMessage

{
  "action": "应用更新",
  "title": "OooPlay",
  "link": "https://www.pgyer.com/oooplay_test",
  "message": "您的应用OooPlay有了新的版本(2.4)更新。",
  "type": "updateVersion",
  "os_version": "2.4",
  "build_version": "139",
  "created": "2015-10-09 11:25:16",
  "updated": "2015-10-09 11:25:16",
  "timestamp": 1444361118,
  "appsize": "2238036",
  "device_type": 'iOS',
  "notes": "修复了一些小弱智的小bug"
}

public class PgyerMessage {

    public String action;
    public String title;
    public String link;
    public String message;
    public String type;
    public String os_version;
    public String build_version;
    public String created;
    public String updated;
    public int timestamp;
    public String appsize;
    public String device_type;
    public String notes;

    @Override
    public String toString() {
        return "PgyerMessage{" +
                "action='" + action + '\'' +
                ", title='" + title + '\'' +
                ", link='" + link + '\'' +
                ", message='" + message + '\'' +
                ", type='" + type + '\'' +
                ", os_version='" + os_version + '\'' +
                ", build_version='" + build_version + '\'' +
                ", created='" + created + '\'' +
                ", updated='" + updated + '\'' +
                ", timestamp=" + timestamp +
                ", appsize='" + appsize + '\'' +
                ", device_type='" + device_type + '\'' +
                ", notes='" + notes + '\'' +
                '}';
    }
}

此处有个小技巧,IDEA IntelliJ有个好用的插件GsonFormat可一键将Json字符串转换为Java Model

钉钉消息则分为几种类型,具体举例可参考钉钉doc

public static final String TYPE_LINK = "link";

public static final String TYPE_MARKDOWN = "markdown";

public static final String TYPE_TEXT = "text";

public static final String TYPE_ACTIONCARD = "actionCard";

public static final String TYPE_FEEDCARD = "feedCard";

此处我们选择markdown类型.为了便于拓展,此处将消息抽取了个基类BaseDingMessage.

public class BaseDingMessage {

    public static final String TYPE_LINK = "link";

    public static final String TYPE_MARKDOWN = "markdown";

    public static final String TYPE_TEXT = "text";

    public static final String TYPE_ACTIONCARD = "actionCard";

    public static final String TYPE_FEEDCARD = "feedCard";

    public String msgtype;
  
  	public AtBean at;

    public static class AtBean {
        public boolean isAtAll;
        public List<String> atMobiles;
    }
}

public class MarkdownMessage  extends BaseDingMessage {

    public MarkdownBean markdown;

    public static class MarkdownBean {

        public String title;
        public String text;
    }
}

代码实现

首先在build.gradle中导入依赖

compile group: 'com.alibaba', name: 'fastjson', version: '1.2.45'
compile group: 'com.squareup.okhttp3', name: 'okhttp', version: '3.9.0'

fastjson是用力啊转化json,okhttp用来网络请求

spring-mvc.xml加入json配置

    </mvc:annotation-driven>

    <!-- 静态资源映射器 -->

</beans>

消息发送服务DingServiceImpl.java

Service
public class DingServiceImpl implements DingService {

    private static final Logger logger = Logger.getLogger(DingServiceImpl.class);

    @Override
    public void send(BaseDingMessage message,String url) {
        MediaType jsonType = MediaType.parse("application/json; charset=utf-8");
        okhttp3.RequestBody body = okhttp3.RequestBody.create(jsonType, JSON.toJSONString(message));
        final Request request = new Request.Builder()
                .url(url)
                .post(body)
                .build();
        OkHttpClient client = OkhttpProvider.get();
        try {
            client.newCall(request).execute();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

蒲公英请求控制器PgyerController.java

@RestController
@RequestMapping("/pgyer")
public class PgyerController {

    @Autowired
    DingService dingService;

    private static final Logger logger = Logger.getLogger(PgyerController.class);

    @ResponseBody
    @RequestMapping(value = "/update",method = RequestMethod.POST)
    public BaseDingMessage apkUpdate(@RequestBody PgyerMessage pgyerMessage){
        BaseDingMessage dingMessage = WebhookConverter.pgyer2Ding(pgyerMessage);
        dingService.send(dingMessage, Urls.DING_TEST);
        logger.info(dingMessage);
        return dingMessage;
    }
}

其中Urls.DING_TEST为钉钉机器人的会话token地址,后面会说明如何创建/获取

消息转换器WebhookConverter.java

public class WebhookConverter {

    private static final Logger logger = Logger.getLogger(WebhookConverter.class);

    public static MarkdownMessage pgyer2Ding(PgyerMessage pgyerMessage){
        MarkdownMessage message = new MarkdownMessage();
        message.msgtype = BaseDingMessage.TYPE_MARKDOWN;
        message.markdown = new MarkdownMessage.MarkdownBean();
        message.markdown.title = pgyerMessage.device_type + "蒲公英更新";
        StringBuilder builder = new StringBuilder();
        builder.append("#### ").append(pgyerMessage.device_type).append("测试包已更新! \n\n")
        .append("###### version: ").append(pgyerMessage.os_version).append(" | build ").append(pgyerMessage.build_version).append("\n\n")
        .append("更新内容:\n").append("> ").append(pgyerMessage.notes).append("\n\n")
        .append("![qr_code_test](图片地址)\n\n")
        .append("[下载地址](https://www.pgyer.com/你的apk地址) 密码:你的密码\n").append(" @18810100000 @18810100001 @18818100002 ");

        message.markdown.text = builder.toString();
        message.at = new BaseDingMessage.AtBean();
        message.at.isAtAll = false;
        message.at.atMobiles = Arrays.asList("18818100000","18818100001","18818100002");

        return message;
    }
}

以上需自行修改内容.

然后创建钉钉机器人.创建四连

点此复制钉钉机器人会话token,建立Urls.java.

public interface Urls {

    /**
     * 提测群机器人token
     */
    String DING_TEST = "钉钉token";
}

此处的Ding_Test即为上面复制的地址

至此,代码主要实现类已经完成,接下来需要去配置蒲公英webhook

配置webhook

打开蒲公英应用设置

创建webhook,写入PgyerController的更新请求地址,如果配置与本文的相同,地址则为

http://你的地址:端口/webhook-1.0-SNAPSHOT/pgyer/update

其中webhook-1.0-SNAPSHOT为war包在tomcat解压后的名称

done! 之后只要上传成功后,即有钉钉消息通知并@测试人员了!

让我们再看下打包后的消息通知!

类似的,代码push,merge也可以做成webhook消息.

Github、Gitlab既有成熟的对接机器人.而笔者使用的Coding是没有与钉钉做对接的,此时可自定义机器人实现,有兴趣的同学可参考上面的教程自行实现.
