Box sdk python or curl to check if a folder exists using folder name

When working with the Box SDK in Python or using curl, you may come across the need to check if a folder exists using its name. In this article, we will explore three different ways to solve this problem.

Option 1: Using the Box SDK

If you are using the Box SDK in Python, you can easily check if a folder exists by making use of the get_folder() method provided by the SDK. This method retrieves a folder object based on its name.


import boxsdk

def check_folder_exists(folder_name):
    client = boxsdk.Client()
    root_folder = client.folder(folder_id='0')
    try:
        folder = root_folder.get_folder(folder_name)
        return True
    except boxsdk.exception.BoxAPIException:
        return False

folder_name = "My Folder"
exists = check_folder_exists(folder_name)
print(f"The folder '{folder_name}' exists: {exists}")

In this code snippet, we first create a Box client object and obtain the root folder. Then, we attempt to retrieve the folder object using the get_folder() method. If the folder exists, the method call will be successful, and we return True. Otherwise, if the folder does not exist, a BoxAPIException will be raised, and we return False.

Option 2: Using curl

If you prefer using curl instead of the Box SDK, you can achieve the same result by making a GET request to the Box API and checking the response status code. A successful request with a status code of 200 indicates that the folder exists.


import subprocess

def check_folder_exists(folder_name):
    command = f"curl -s -o /dev/null -w '%{{http_code}}' 'https://api.box.com/2.0/folders/0/items?name={folder_name}'"
    response_code = subprocess.check_output(command, shell=True)
    return response_code == b'200'

folder_name = "My Folder"
exists = check_folder_exists(folder_name)
print(f"The folder '{folder_name}' exists: {exists}")

In this code snippet, we use the subprocess module to execute the curl command. The command sends a GET request to the Box API, specifying the folder name as a query parameter. The -s flag suppresses the progress meter, and the -o /dev/null flag discards the response body. The -w '%{{http_code}}' flag prints only the HTTP status code. We then compare the response code with b'200' to determine if the folder exists.

Option 3: Using the Box SDK and curl

If you want to combine the advantages of both the Box SDK and curl, you can use the Box SDK to retrieve the folder ID and then make a curl request to check if the folder exists.


import boxsdk
import subprocess

def check_folder_exists(folder_name):
    client = boxsdk.Client()
    root_folder = client.folder(folder_id='0')
    try:
        folder = root_folder.get_folder(folder_name)
        folder_id = folder.id
        command = f"curl -s -o /dev/null -w '%{{http_code}}' 'https://api.box.com/2.0/folders/{folder_id}'"
        response_code = subprocess.check_output(command, shell=True)
        return response_code == b'200'
    except boxsdk.exception.BoxAPIException:
        return False

folder_name = "My Folder"
exists = check_folder_exists(folder_name)
print(f"The folder '{folder_name}' exists: {exists}")

In this code snippet, we first use the Box SDK to retrieve the folder object. If the folder exists, we obtain its ID and use it in the curl command to check the response status code. If the folder does not exist, a BoxAPIException will be raised, and we return False.

After exploring these three options, it is clear that using the Box SDK (Option 1) is the most straightforward and recommended approach. It provides a higher level of abstraction and handles the API calls internally, making the code more readable and maintainable. However, if you prefer using curl or want to combine both approaches, Options 2 and 3 can also be viable alternatives depending on your specific requirements.
