Alibaba Cloud CDN Skill

Manage CDN content delivery network via the @alicloud/cdn20180510 TypeScript SDK.

Prerequisites

npm install @alicloud/cdn20180510 @alicloud/openapi-core @darabonba/typescript

export ALIBABA_CLOUD_ACCESS_KEY_ID="<your-key-id>"
export ALIBABA_CLOUD_ACCESS_KEY_SECRET="<your-key-secret>"

See scripts/setup_client.ts for a reusable client factory, and references/quickstart.md for full setup including endpoints, domain types, source types, function configurations, and time formats.

Client Initialization

import Client from '@alicloud/cdn20180510';
import { Config } from '@alicloud/openapi-core';

const client = new Client(new Config({
  accessKeyId: process.env.ALIBABA_CLOUD_ACCESS_KEY_ID,
  accessKeySecret: process.env.ALIBABA_CLOUD_ACCESS_KEY_SECRET,
  endpoint: 'cdn.aliyuncs.com',
}));

CDN is a global service — use the single endpoint cdn.aliyuncs.com for all operations.

Core Patterns

RPC-Style (Global Service)

CDN APIs do not require regionId. Parameters are flat fields in a Request object:

import * as models from '@alicloud/cdn20180510/dist/models';

const { body } = await client.describeUserDomains(new models.DescribeUserDomainsRequest({
  pageSize: 50,
  pageNumber: 1,
}));

Domain Configuration via JSON Functions

Use batchSetCdnDomainConfig with a JSON functions array to configure domain features:

await client.batchSetCdnDomainConfig(new models.BatchSetCdnDomainConfigRequest({
  domainNames: 'cdn.example.com',
  functions: JSON.stringify([
    {
      functionName: 'filetype_based_ttl_set',
      functionArgs: [
        { argName: 'ttl', argValue: '2592000' },
        { argName: 'file_type', argValue: 'jpg,png,gif,css,js' },
        { argName: 'weight', argValue: '1' },
      ],
    },
  ]),
}));

Page-Based Pagination

let pageNumber = 1;
let all: any[] = [];
while (true) {
  const { body } = await client.describeUserDomains(new models.DescribeUserDomainsRequest({
    pageSize: 50, pageNumber,
  }));
  all.push(...(body.domains?.pageData || []));
  if (all.length >= (body.totalCount || 0)) break;
  pageNumber++;
}

Time Range for Monitoring

Most monitoring APIs accept ISO 8601 time ranges:

const { body } = await client.describeDomainRealTimeQpsData(
  new models.DescribeDomainRealTimeQpsDataRequest({
    domainName: 'cdn.example.com',
    startTime: '2026-02-15T00:00:00Z',
    endTime: '2026-02-16T00:00:00Z',
  })
);

Error Handling

try {
  await client.addCdnDomain(request);
} catch (err: any) {
  console.error(`Code: ${err.code}, Message: ${err.message}, RequestId: ${err.data?.RequestId}`);
}

Common Workflows

1. Add and Configure CDN Domain

addCdnDomain → verifyDomainOwner → setCdnDomainSSLCertificate → batchSetCdnDomainConfig

2. SSL Certificate Management

describeCdnCertificateList → setCdnDomainSSLCertificate → describeCdnDomainCertificateInfo

3. Cache Refresh & Prefetch

refreshObjectCaches (URL/Dir) → pushObjectCache → describeRefreshTasks → describeRefreshQuota

4. Real-Time Monitoring

describeDomainRealTimeQpsData → describeDomainRealTimeBpsData → describeDomainRealTimeHttpCodeData

5. Traffic Analysis

describeDomainTopUrlVisit → describeDomainTopClientIpVisit → describeDomainISPData → describeDomainRegionData

6. Log Management

describeCdnDomainLogs → createRealTimeLogDelivery → describeRealtimeDeliveryAcc

7. Usage & Billing

describeCdnUserBillType → describeDomainUsageData → createUsageDetailDataExportTask

8. IP Verification & Blocking

describeIpInfo → setCdnFullDomainsBlockIP → describeCdnFullDomainsBlockIPHistory

See references/workflows.md for detailed workflow examples with full code.

API Reference Quick Index

Load the corresponding reference file for parameter details:

• Domain CRUD/batch/verification/ownership: references/domain.md
• Function configs/staging/gray deployment: references/domain-config.md
• SSL/TLS certificate binding: references/certificate.md
• URL/directory refresh and prefetch: references/cache-refresh.md
• Real-time QPS/BPS/hit rate/HTTP codes/traffic: references/monitoring.md
• Access logs/real-time log delivery: references/log.md
• Usage data/billing/quota/export: references/usage.md
• IP check/VIP query/IP blocking: references/ip-tool.md
• Edge function triggers: references/fc-trigger.md
• Scheduled delivery/report tasks: references/deliver-task.md
• Resource tagging: references/tag-resource.md

Each reference file contains per-API documentation with method signatures and parameter tables.
