如何使用Python请求和图形API在Facebook上发布图像？

import requests

def publish_image_on_facebook(image_path, message, access_token):
    url = 'https://graph.facebook.com/me/photos'
    params = {
        'access_token': access_token,
        'message': message
    }
    files = {
        'source': open(image_path, 'rb')
    }

    response = requests.post(url, params=params, files=files)
    if response.status_code == 200:
        print('Image published successfully!')
    else:
        print('Failed to publish image.')

# 使用示例
image_path = 'path/to/image.jpg'
message = 'Check out this amazing image!'
access_token = 'your_access_token'

publish_image_on_facebook(image_path, message, access_token)
