Tencent Cloud CDN SDK for Python

3.1.89 verified Sat May 09 auth: no python

Official Tencent Cloud SDK for the Content Delivery Network (CDN) service. Version 3.1.89. Monthly release cadence closely following the SDK generator.

pip install tencentcloud-sdk-python-cdn

Common errors

error ModuleNotFoundError: No module named 'tencentcloud' ↓

cause Missing base tencentcloud-sdk-python package or the specific CDN package.

fix

Run 'pip install tencentcloud-sdk-python-cdn'. This installs the common dependency automatically.

error AttributeError: module 'tencentcloud' has no attribute 'cdn' ↓

cause Attempting to import from 'tencentcloud.cdn' directly without specifying versioned module.

fix

Use the correct import: from tencentcloud.cdn.v20180606 import cdn_client

error tencentcloud.common.exception.TencentCloudSDKException: Failed to parse SSEResponse ↓

cause Incorrect request parameters or malformed JSON. Often due to missing required fields like 'Domain' or wrong date format.

fix

Verify request model fields using the API documentation. Use the correct model class from models module.

Warnings

breaking In version 3.0.x and earlier, SDK was installed as a monolithic 'tencentcloud-sdk-python' package. Now each service is a separate package. Ensure you install the correct specific package for CDN. ↓

fix Uninstall the old package (pip uninstall tencentcloud-sdk-python) and install per-service package: pip install tencentcloud-sdk-python-cdn.

gotcha The client constructor requires a region (e.g., 'ap-guangzhou') as second argument, even for global services like CDN. Using an empty string may lead to unexpected behavior. ↓

fix Always specify a valid region string, typically 'ap-guangzhou' for CDN.

deprecated The older authentication method using SecretId/SecretKey directly in code is discouraged. Use environment variables or Tencent Cloud CAM roles. ↓

fix Use Credential constructor with environment variables or assume-role.

Imports

CdnClient
wrong
```
from tencentcloud.cdn import CdnClient
```
correct
```
from tencentcloud.cdn.v20180606 import cdn_client
```
The top-level package does not contain the client class directly. Must import from the versioned module.

Quickstart

Standard quickstart using environment variables for credentials and calling DescribeCdnData.

import os
from tencentcloud.common import credential
from tencentcloud.cdn.v20180606 import cdn_client, models

cred = credential.Credential(
    os.environ.get('TENCENTCLOUD_SECRET_ID', ''),
    os.environ.get('TENCENTCLOUD_SECRET_KEY', '')
)
client = cdn_client.CdnClient(cred, "ap-guangzhou")
req = models.DescribeCdnDataRequest()
req.Metric = "flux"
req.Domain = "example.com"
req.StartTime = "2023-01-01 00:00:00"
req.EndTime = "2023-01-02 00:00:00"
resp = client.DescribeCdnData(req)
print(resp)
