Single-URL Speed Limits

Last updated: 2022-03-04 11:12:45

    Overview

    This document provides an overview of APIs and SDK code samples related to single-URL speed limits.

    Note:

    The speed range is 819200 to 838860800 (in bit/s), that is, 100 KB/s to 100 MB/s. If a value is not within this range, 400 will be returned.

    Setting an upload speed limit

    // Before using the advanced API, ensure that the process contains a TransferManager instance. If such an instance does not exist, create one.
    // For the detailed code, see "Advanced APIs -> Creating a TransferManager instance" on the current page.
    TransferManager transferManager = createTransferManager();
    // Enter the bucket name in the format of `BucketName-APPID`.
    String bucketName = "examplebucket-1250000000";
    // Object key, the unique ID of an object in a bucket. For more information, please see [Object Key](https://www.tencentcloud.com/document/product/436/13324).
    String key = "exampleobject";
    // Here, a ByteArrayInputStream stream is created as an example. In practice, you should create a stream of the actual InputStream type to upload.
    long inputStreamLength = 1024 * 1024;
    byte data[] = new byte[inputStreamLength];
    InputStream inputStream = new ByteArrayInputStream(data);
    // Here, set the upload bandwidth limit (in bit/s) to 10 MB/s.
    putObjectRequest.setTrafficLimit(80*1024*1024);
    try {
      // The advanced API will return an asynchronous result `Upload`.
      // You can call the `waitForUploadResult` method to wait for the upload to complete. If the upload is successful, `UploadResult` is returned. If the upload fails, an exception is returned.
      Upload upload = transferManager.upload(putObjectRequest);
      UploadResult uploadResult = upload.waitForUploadResult();
    } catch (CosServiceException e) {
      e.printStackTrace();
    } catch (CosClientException e) {
      e.printStackTrace();
    } catch (InterruptedException e) {
      e.printStackTrace();
    }
    // After confirming that the process does not use the TransferManager instance anymore, close it.
    // For the detailed code, see "Advanced APIs -> Closing a TransferManager instance" on the current page.
    shutdownTransferManager(transferManager);
    

    Setting a download speed limit

    // Before using the advanced API, ensure that the process contains a TransferManager instance. If such an instance does not exist, create one.
    // For the detailed code, see "Advanced APIs -> Creating a TransferManager instance" on the current page.
    TransferManager transferManager = createTransferManager();
    // Enter the bucket name in the format of `BucketName-APPID`.
    String bucketName = "examplebucket-1250000000";
    // Object key, the unique ID of an object in a bucket. For more information, please see [Object Key](https://www.tencentcloud.com/document/product/436/13324).
    String key = "exampleobject";
    // Local file path
    String localFilePath = "/path/to/localFile";
    File downloadFile = new File(localFilePath);
    GetObjectRequest getObjectRequest = new GetObjectRequest(bucketName, key);
    // Here, set the download bandwidth limit (in bit/s) to 10 MB/s.
    getObjectRequest.setTrafficLimit(80*1024*1024);
    try {
      // Return an asynchronous result `Download`. You can synchronously call `waitForCompletion` to wait for the download to end. If successful, `void` is returned; otherwise, an exception will be thrown.
      Download download = transferManager.download(getObjectRequest, downloadFile);
      download.waitForCompletion();
    } catch (CosServiceException e) {
      e.printStackTrace();
    } catch (CosClientException e) {
      e.printStackTrace();
    } catch (InterruptedException e) {
      e.printStackTrace();
    }
    // After confirming that the process does not use the TransferManager instance anymore, close it.
    // For the detailed code, see "Advanced APIs -> Closing a TransferManager instance" on the current page.
    shutdownTransferManager(transferManager);
