IBM Watson令牌将在一小时后过期。刷新令牌的代码？

import requests

# 设置认证信息
url = "https://iam.cloud.ibm.com/identity/token"
headers = {
    "Content-Type": "application/x-www-form-urlencoded",
    "Accept": "application/json"
}
data = {
    "grant_type": "urn:ibm:params:oauth:grant-type:apikey",
    "apikey": "YOUR_API_KEY"
}

# 发送请求获取新的令牌
response = requests.post(url, headers=headers, data=data)
token = response.json()["access_token"]

# 更新令牌
# TODO: 将新的令牌应用到你的代码中

# 打印新的令牌
print("刷新后的令牌：", token)
