使用IBM hpc-cluster api时，如何使用IAM令牌进行身份验证？

curl -X POST "https://iam.cloud.ibm.com/identity/token" \
     -H "Content-Type: application/x-www-form-urlencoded" \
     -d "grant_type=urn:ibm:params:oauth:grant-type:apikey&apikey=YOUR_API_KEY"

import requests

# 设置IAM令牌
iam_token = "YOUR_IAM_TOKEN"

# 设置请求头
headers = {
    "Authorization": f"Bearer {iam_token}",
    "Content-Type": "application/json"
}

# 发送API请求
response = requests.get("https://your-hpc-cluster-api-endpoint", headers=headers)

# 检查响应
if response.status_code == 200:
    print("Request was successful")
    print(response.json())
else:
    print(f"Request failed with status code {response.status_code}")
    print(response.text)

import requests

# 获取IAM令牌
def get_iam_token(api_key):
    url = "https://iam.cloud.ibm.com/identity/token"
    headers = {
        "Content-Type": "application/x-www-form-urlencoded"
    }
    data = {
        "grant_type": "urn:ibm:params:oauth:grant-type:apikey",
        "apikey": api_key
    }
    response = requests.post(url, headers=headers, data=data)
    response.raise_for_status()
    return response.json()["access_token"]

# 设置API密钥
api_key = "YOUR_API_KEY"

# 获取IAM令牌
iam_token = get_iam_token(api_key)

# 设置请求头
headers = {
    "Authorization": f"Bearer {iam_token}",
    "Content-Type": "application/json"
}

# 发送API请求
response = requests.get("https://your-hpc-cluster-api-endpoint", headers=headers)

# 检查响应
if response.status_code == 200:
    print("Request was successful")
    print(response.json())
else:
    print(f"Request failed with status code {response.status_code}")
    print(response.text)
