Uploading Streaming Data
Sample Code
Use the initialized client instance to upload your streaming data to DIS through a DIS stream.
The code for uploading streaming data is as follows:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 |
//Initialize the DIS SDK client instance. For details about endpoints, AKs, SKs, regions, and project IDs, see the following: DIS dic = DISClientBuilder.standard() .withEndpoint("xxxx") .withAk("xxxx") .withSk("xxxx") .withProjectId("xxxx") .withRegion("xxxx") .build(); //Configure the stream name. String streamName = "xxxx"; //Configure the data to be uploaded. String message = "hello world."; PutRecordsRequest putRecordsRequest = new PutRecordsRequest(); putRecordsRequest.setStreamName(streamName); List<PutRecordsRequestEntry> putRecordsRequestEntryList = new ArrayList<PutRecordsRequestEntry>(); ByteBuffer buffer = ByteBuffer.wrap(message.getBytes()); for (int i = 0; i < 3; i++) { PutRecordsRequestEntry putRecordsRequestEntry = new PutRecordsRequestEntry(); putRecordsRequestEntry.setData(buffer); putRecordsRequestEntry.setPartitionKey(String.valueOf(ThreadLocalRandom.current().nextInt(1000000))); putRecordsRequestEntryList.add(putRecordsRequestEntry); } putRecordsRequest.setRecords(putRecordsRequestEntryList); LOGGER.info("========== BEGIN PUT ============"); PutRecordsResult putRecordsResult = null; try { putRecordsResult = dic.putRecords(putRecordsRequest); } catch (DISClientException e) { LOGGER.error("Failed to get a normal response, please check params and retry. Error message [{}]", e.getMessage(), e); } catch (Exception e) { LOGGER.error(e.getMessage(), e); } |
