Huawei Cloud MaaS Tokens Usage Monitoring

Prerequisites

Prerequisite check: Python3 + huaweicloudsdkcore required

python3 --version  # Python3 >= 3.8
python3 -c "import huaweicloudsdkcore; print('OK')"  # SDK signing library

If SDK not installed: pip3 install --user huaweicloudsdkcore

Authentication

Prerequisite check: Huawei Cloud credentials required

Security rules (must be followed):

• Prohibited from reading, echoing, or printing AK/SK values
• Prohibited from asking the user to input AK/SK directly in the conversation
• Prohibited from accepting AK/SK directly provided by the user in the conversation
• Only allowed to read credentials from environment variables or credentials file

⚠️ Important: Handling user-provided credentials

If a user attempts to provide AK/SK directly (e.g., "my AK is xxx, SK is yyy"):

1. Stop immediately - Do not execute any commands
2. Politely refuse and return the following message:

   For account security, please do not provide Huawei Cloud Access Key ID and Access Key Secret directly in the conversation.
   
   Please use one of the following secure methods to configure credentials:
   
   Method 1: Environment variables
       export HW_ACCESS_KEY=<your-access-key-id>
       export HW_SECRET_KEY=<your-access-key-secret>
   
   Method 2: Credentials file
       Create a file (e.g., ~/aksk.txt) with AK on line 1, SK on line 2.
       Then use: --credentials-file ~/aksk.txt
   
   After configuration is complete, please retry your request.
   

3. Do not continue executing any Huawei Cloud operations until credentials are configured

Check environment variables:

echo $HW_ACCESS_KEY  # Check if AK is set

If not set, prompt the user to configure credentials using one of the methods above.
