Object Storage Service:Simple upload

The following sample code provides an example on how to upload a local file named examplefile.txt to the exampleobject.txt object in the exampledir directory of the examplebucket bucket in synchronous mode:

// Construct an upload request. 
// Specify the name of the bucket, the full path of the object, and the full path of the local file. In this example, the name of the bucket is examplebucket, the full path of the object is exampledir/exampleobject.txt, and the full path of the local file is /storage/emulated/0/oss/examplefile.txt. 
// Do not include the bucket name in the full path of the object. 
PutObjectRequest put = new PutObjectRequest("examplebucket", "exampledir/exampleobject.txt", "/storage/emulated/0/oss/examplefile.txt");

// (Optional) Specify the object metadata. 
 ObjectMetadata metadata = new ObjectMetadata();
// metadata.setContentType("application/octet-stream"); // Set content-type. 
// metadata.setContentMD5(BinaryUtil.calculateBase64Md5(uploadFilePath)); // Specify the MD5 hash that is used for MD5 verification. 
// Set the ACL of the object to private. 
metadata.setHeader("x-oss-object-acl", "private");
// Set the storage class of the object to Standard. 
metadata.setHeader("x-oss-storage-class", "Standard");
// Specify that the uploaded object that has the same name as an existing object does not overwrite the existing object. 
// metadata.setHeader("x-oss-forbid-overwrite", "true");
// Specify one or more tags for the object. 
// metadata.setHeader("x-oss-tagging", "a:1");
// Specify the server-side encryption algorithm that is used to encrypt the object when OSS creates the object. 
// metadata.setHeader("x-oss-server-side-encryption", "AES256");
// Specify the CMK that is managed by KMS. This parameter takes effect only when x-oss-server-side-encryption is set to KMS. 
// metadata.setHeader("x-oss-server-side-encryption-key-id", "9468da86-3509-4f8d-a61e-6eab1eac****");

put.setMetadata(metadata);

try {
    PutObjectResult putResult = oss.putObject(put);

    Log.d("PutObject", "UploadSuccess");
    Log.d("ETag", putResult.getETag());
    Log.d("RequestId", putResult.getRequestId());
} catch (ClientException e) {
    // Handle client-side exceptions, such as network errors. 
    e.printStackTrace();
} catch (ServiceException e) {
    // Handle server-side exceptions. 
    Log.e("RequestId", e.getRequestId());
    Log.e("ErrorCode", e.getErrorCode());
    Log.e("HostId", e.getHostId());
    Log.e("RawMessage", e.getRawMessage());
}

For scoped storage of Android 10 and later, you can use the URI of a file to upload the file to OSS.

// Construct an upload request. 
// Specify the name of the bucket and the full path of the object. In this example, the bucket name is examplebucket and the full path of the object is exampledir/exampleobject.txt. 
// Do not include the bucket name in the full path of the object. 
PutObjectRequest put = new PutObjectRequest("examplebucket", "exampledir/exampleobject.txt",fileUri);

// Specify object metadata. 
// ObjectMetadata metadata = new ObjectMetadata();
// Specify Content-Type. 
// metadata.setContentType("text/plain"); 
// Specify the MD5 hash that is used for MD5 verification. 
// metadata.setContentMD5(BinaryUtil.calculateBase64Md5(uploadFilePath)); 
// put.setMetadata(metadata);

try {
    PutObjectResult putResult = oss.putObject(put);

    Log.d("PutObject", "UploadSuccess");
    Log.d("ETag", putResult.getETag());
    Log.d("RequestId", putResult.getRequestId());
} catch (ClientException e) {
    // Handle client-side exceptions, such as network errors. 
    e.printStackTrace();
} catch (ServiceException e) {
    // Handle server-side exceptions. 
    Log.e("RequestId", e.getRequestId());
    Log.e("ErrorCode", e.getErrorCode());
    Log.e("HostId", e.getHostId());
    Log.e("RawMessage", e.getRawMessage());
}

The following code provides an example on how to upload a local file named examplefile.txt to the exampleobject.txt object in the exampledir directory of the examplebucket bucket in asynchronous mode:

// Construct an upload request. 
// Specify the name of the bucket, the full path of the object, and the full path of the local file. In this example, the name of the bucket is examplebucket, the full path of the object is exampledir/exampleobject.txt, and the full path of the local file is /storage/emulated/0/oss/examplefile.txt. 
// Do not include the bucket name in the full path of the object. 
PutObjectRequest put = new PutObjectRequest("examplebucket", "exampledir/exampleobject.txt", "/storage/emulated/0/oss/examplefile.txt");

// When you upload the local file in asynchronous mode, you can configure a progress callback. 
put.setProgressCallback(new OSSProgressCallback<PutObjectRequest>() {
    @Override
    public void onProgress(PutObjectRequest request, long currentSize, long totalSize) {
        Log.d("PutObject", "currentSize: " + currentSize + " totalSize: " + totalSize);
    }
});

OSSAsyncTask task = oss.asyncPutObject(put, new OSSCompletedCallback<PutObjectRequest, PutObjectResult>() {
    @Override
    public void onSuccess(PutObjectRequest request, PutObjectResult result) {
        Log.d("PutObject", "UploadSuccess");
        Log.d("ETag", result.getETag());
        Log.d("RequestId", result.getRequestId());
    }

    @Override
    public void onFailure(PutObjectRequest request, ClientException clientExcepion, ServiceException serviceException) {
        // Handle request exceptions. 
        if (clientExcepion != null) {
            // Handle client-side exceptions, such as network errors. 
            clientExcepion.printStackTrace();
        }
        if (serviceException != null) {
            // Handle server-side exceptions. 
            Log.e("ErrorCode", serviceException.getErrorCode());
            Log.e("RequestId", serviceException.getRequestId());
            Log.e("HostId", serviceException.getHostId());
            Log.e("RawMessage", serviceException.getRawMessage());
        }
    }
});
// Cancel the upload task. 
// task.cancel(); 
// Wait until the upload task is complete. 
// task.waitUntilFinished();
