如何使用github api列出一个目录下的所有文件名？

import requests

def list_files_in_directory(repo_owner, repo_name, directory_path, access_token):
    headers = {
        "Authorization": f"Bearer {access_token}"
    }
    url = f"https://api.github.com/repos/{repo_owner}/{repo_name}/contents/{directory_path}"
    response = requests.get(url, headers=headers)
    if response.status_code == 200:
        files = [file["name"] for file in response.json()]
        return files
    else:
        return None

# 使用示例
repo_owner = "your_github_username"
repo_name = "your_repository_name"
directory_path = "path_to_directory"
access_token = "your_personal_access_token"

files = list_files_in_directory(repo_owner, repo_name, directory_path, access_token)
if files:
    for file in files:
        print(file)
else:
    print("Failed to retrieve file list.")
