This example shows the process of deleting a PID relation named “PID_MingduanTest” in the daily region.

  1. public static void main(String []args) {
  2. String regionId = "cn-hangzhou";
  3. String accessKey = "XXXXXXXXXXXXXXXXX";
  4. String secretKey = "XXXXXXXXXXXXXXXXX";
  5. String endPointName ="cn-hangzhou";
  6. String productName ="Ons";
  7. String domain ="ons.cn-hangzhou.aliyuncs.com";
  8. /**
  9. *Select Region based on the region you will access, and set the corresponding access point.
  10. */
  11. try {
  12. DefaultProfile.addEndpoint(endPointNameregionIdproductNamedomain);
  13. } catch (ClientException e) {
  14. e.printStackTrace();
  15. }
  16. IClientProfile profile= DefaultProfile.getProfile(regionIdaccessKeysecretKey);
  17. IAcsClient iAcsClient= new DefaultAcsClient(profile);
  18. OnsPublishDeleteRequest request = new OnsPublishDeleteRequest();
  19. /**
  20. *OnsRegionId refers to the resource of the region of MQ required to be accessed by API.

  24. request.setPreventCache(System.currentTimeMillis());
  25. request.setAcceptFormat(FormatType.JSON);
  26. request.setTopic("Mingduan_67dd");
  27. request.setProducerId("PID_MingduanTest");
  28. try {
  29. OnsPublishDeleteResponse response=iAcsClient.getAcsResponse(request);
  30. System.out.println(response.getRequestId());
  31. } catch (ServerException e) {
