Imgur API授权问题

import requests

# 配置参数

# 获取授权码
auth_url = f'https://api.imgur.com/oauth2/authorize?client_id={client_id}&response_type=code&redirect_uri={redirect_uri}'
print(f'Please navigate to: {auth_url}')

# 用户授权后获取授权码
auth_code = input('Enter the authorization code: ')

# 交换访问令牌
token_url = 'https://api.imgur.com/oauth2/token'

    'client_id': client_id,
    'client_secret': client_secret,
    'grant_type': 'authorization_code',
    'code': auth_code,
    'redirect_uri': redirect_uri
}
response = requests.post(token_url, data=data)
access_token = response.json().get('access_token')

# 使用访问令牌调用 API
headers = {
    'Authorization': f'Bearer {access_token}'
}
image_url = 'https://api.imgur.com/3/image/random'
response = requests.get(image_url, headers=headers)
print(response.json())
