How can I view the number of files of a certain type (such as the number of images) under COS?

To view the number of files of a certain type, such as images, in COS (Cloud Object Storage), you can use the following methods:

Method 1: Use the COS Management Console

1. Log in to the COS Management Console: Go to the COS console interface.
2. Select the Bucket: Choose the bucket where your files are stored.
3. Filter Files by Type: In the file list interface, you can use the search or filter function to filter files by file type. For example, if you want to view the number of images, you can enter the image file extension (such as .jpg, .png) in the search box to filter out the relevant image files.
4. View the Number of Files: After filtering, the console will display the filtered file list, and you can view the number of files at the top or bottom of the list.

Method 2: Use COS APIs

You can also use COS APIs to programmatically retrieve the number of files of a certain type. The following is a simple Python code example using the COS SDK:

import cos-python-sdk-v5

# Initialize the COS client
secret_id = 'your_secret_id'
secret_key = 'your_secret_key'
region = 'ap-beijing'
token = None
scheme = 'https'
config = cos-python-sdk-v5.CosConfig(Region=region, SecretId=secret_id, SecretKey=secret_key, Token=token, Scheme=scheme)
client = cos-python-sdk-v5.CosS3Client(config)

bucket = 'your_bucket_name'
prefix = ''
delimiter = ''
marker = ''
max_keys = 1000
file_type = '.jpg'  # Specify the file type you want to count, here is jpg

count = 0
while True:
    response = client.list_objects(
        Bucket=bucket,
        Prefix=prefix,
        Delimiter=delimiter,
        Marker=marker,
        MaxKeys=max_keys
    )
    if 'Contents' in response:
        for content in response['Contents']:
            if content['Key'].endswith(file_type):
                count = count + 1
    if response['IsTruncated'] == 'false':
        break
    marker = response['NextMarker']

print(f"The number of {file_type} files is: {count}")
