如何通过GitLab REST API获取文件的原始内容？

import requests

# GitLab实例的URL
gitlab_url = 'https://your-gitlab-instance.com/api/v4'

# 你的访问令牌
access_token = 'your-access-token'

# 项目ID和文件路径
project_id = 'your-project-id'
file_path = 'path/to/your/file.txt'

# 构造API请求URL
api_url = f'{gitlab_url}/projects/{project_id}/repository/files/{file_path}/raw?ref=master'

# 设置请求头
headers = {
    'Private-Token': access_token
}

# 发送GET请求
response = requests.get(api_url, headers=headers)

# 检查响应状态码
if response.status_code == 200:
    # 获取文件内容
    file_content = response.text
    print(file_content)
else:
    print(f'Failed to get file content: {response.status_code}')
