# Obtain an AK and SK pair on the management console. For details, see https://support.huaweicloud.com/intl/en-us/usermanual-ca/ca_01_0003.html.
ak = os.getenv("AccessKeyID")
sk = os.getenv("SecretAccessKey")
# (Optional) If you use a temporary AK and SK pair and a security token to access OBS, obtain them from environment variables.
security_token = os.getenv("SecurityToken")
# Set server to the endpoint corresponding to the bucket. Here uses CN-Hong Kong as an example. Replace it with the one in use.
server = "https://obs.ap-southeast-1.myhuaweicloud.com"

# Create an obsClient instance.
# If you use a temporary AK and SK pair and a security token to access OBS, you must specify security_token when creating an instance.

# Obtain the upload progress.
def callback(transferredAmount, totalAmount, totalSeconds):
    # Obtain the average upload rate (KB/s).
    print(transferredAmount * 1.0 / totalSeconds / 1024)
    # Obtain the upload progress in percentage.
    print(transferredAmount * 100.0 / totalAmount)

try:
    bucketName = "examplebucket"
    # Specify an object name (the name displayed after the file is uploaded to the bucket).
    objectKey = "objectname"
    # Specify the full path of the file or folder to be uploaded, for example, aa/bb.txt or aa/.
    file_path = 'localfile'
    # Perform the file-based upload.
    resp = obsClient.putFile(bucketName, objectKey, file_path, progressCallback=callback)
    # If status code 2xx is returned, the API is called successfully. Otherwise, the API call fails.
    if resp.status < 300:
        print('Put File Succeeded')
        print('requestId:', resp.requestId)
        print('etag:', resp.body.etag)
        print('versionId:', resp.body.versionId)
        print('storageClass:', resp.body.storageClass)
    else:
        print('Put File Failed')
        print('requestId:', resp.requestId)
        print('errorCode:', resp.errorCode)
        print('errorMessage:', resp.errorMessage)
except:
    print('Put File Failed')
    print(traceback.format_exc())

You can query the upload progress when uploading an object in streaming, file-based, multipart, appendable, or resumable mode.
