在第三方API接口对接中，需要及时获取第三方接口请求结果情况，所以在代码中融合钉钉机器人，对请求的异常结果及时发送通知。

1. 自定义机器人参考链接
2. 通用响应参数-封装API的错误码

public interface IErrorCode {long getCode();String getMessage();
}

3. 通用响应参数-状态码

/*** 〈 通用响应参数-状态码 〉** @since JDK1.8* 版本 @version 1.0*/
public enum ResultCode implements IErrorCode {SUCCESS(2000, "操作成功"),FAILED(5000, "操作失败"),VALIDATE_FAILED(4040, "参数检验失败"),UNAUTHORIZED(4010, "暂未登录或token已经过期"),FORBIDDEN(4030, "没有相关权限");private long code;private String message;ResultCode(long code, String message) {this.code = code;this.message = message;}public long getCode() {return code;}public String getMessage() {return message;}
}

4. 通过返回类定义

@Data
@ApiModel(description = "通用响应参数")
@Accessors(chain = true)
@NoArgsConstructor
@AllArgsConstructor
public class CommonResult {@ApiModelProperty(value = "返回码")private long resultCode;@ApiModelProperty(value = "返回信息")private String message;@ApiModelProperty(value = "返回结果集")private Object data;private CommonResult(long resultCode, String message) {this.resultCode = resultCode;this.message = message;}/*** 成功返回结果*/public static CommonResult success() {return new CommonResult(ResultCode.SUCCESS.getCode(), ResultCode.SUCCESS.getMessage());}/*** 失败返回结果*/public static CommonResult failed() {return new CommonResult(ResultCode.FAILED.getCode(), ResultCode.FAILED.getMessage());}/*** 未授权访问返回结果* @return*/public static CommonResult unauthorized(){return new CommonResult(ResultCode.UNAUTHORIZED.getCode(),ResultCode.UNAUTHORIZED.getMessage());}/*** 参数校验失败返回结果* @return*/public static CommonResult validateFailed(){return new CommonResult(ResultCode.VALIDATE_FAILED.getCode(),ResultCode.VALIDATE_FAILED.getMessage());}/*** 没有授权返回结果* @return*/public static CommonResult forbidden(){return new CommonResult(ResultCode.FORBIDDEN.getCode(),ResultCode.FORBIDDEN.getMessage());}/*** 失败返回结果** @param errorCode 错误码*/public static CommonResult common(IErrorCode errorCode) {return new CommonResult(errorCode.getCode(), errorCode.getMessage());}
}

2. 在钉钉群可以通过手机号码@指定人员

/*** 日志接受者，需要在text中包含才可以@* @param mobiles 手机号码集合* @return*/private String phone(List<String> mobiles){StringBuffer stringBuffer = new StringBuffer();for (String mobile : mobiles) {stringBuffer.append(" @"+mobile);}return stringBuffer.toString();}

3. 关于钉钉群机器人配置的通用参数

@Data
@Component
@ConfigurationProperties(prefix = "dingtalk")
public class DingTalkProperties {/*** 数据请求url*/private String url;/*** token*/private String token;/*** 密钥，机器人安全设置页面，加签一栏下面显示的SEC开头的字符串。*/private String secret;/*** 项目民称，用于钉钉机器人发送信息的请求头*/private String projectName;private List<String> atMobiles;
}

4. 发送数据URL

    private String sendUrl() throws NoSuchAlgorithmException, UnsupportedEncodingException, InvalidKeyException {Long timestamp = System.currentTimeMillis();String stringToSign = timestamp + "\n" + dingTalkConfig.getSecret();Mac mac = Mac.getInstance("HmacSHA256");mac.init(new SecretKeySpec(dingTalkConfig.getSecret().getBytes("UTF-8"), "HmacSHA256"));byte[] signData = mac.doFinal(stringToSign.getBytes("UTF-8"));String sign = URLEncoder.encode(new String(Base64.encodeBase64(signData)), "UTF-8");return dingTalkConfig.getUrl() + "?access_token=" + dingTalkConfig.getToken() + "&sign=" + sign + "&timestamp=" + timestamp;}

5. 发送数据service层

    @Overridepublic void sendMessage(CommonResult data) {try {DingTalkClient client = new DefaultDingTalkClient(sendUrl());OapiRobotSendRequest request = new OapiRobotSendRequest();request.setMsgtype("markdown");OapiRobotSendRequest.Markdown markdown = new OapiRobotSendRequest.Markdown();markdown.setTitle("接口异常通知");markdown.setText("#### " + dingTalkConfig.getProjectName() + " \n" +"> 日志处理人：" + phone(dingTalkConfig.getAtMobiles()) + "\n\n" +"> 异常原因：" + data.getMessage() + "\n\n" +"> ###### " + DateUtils.getThisTime() + "发布\n");request.setMarkdown(markdown);OapiRobotSendRequest.At at = new OapiRobotSendRequest.At();at.setAtMobiles(dingTalkConfig.getAtMobiles());// isAtAll类型如果不为Boolean，请升级至最新SDKat.setIsAtAll(false);request.setAt(at);OapiRobotSendResponse response = client.execute(request);} catch (Exception e) {log.error("发送信息错误，失败信息：{}", e.getMessage());}}
