Purge URLs

Last updated: 2020-06-07 22:52:13


    This is a legacy API which has been hidden and will no longer be updated. We recommend using the new CDN API 3.0 which is standardized and faster.

    1. API Description

    This API (RefreshCdnUrl) is used to set specified resources on a node as expired.

    Domain for API request:cdn.api.cloud.tencent.com

    1) Each user is allowed to purge up to 10,000 URLs each day;
    2) A maximum of 1,000 URLs can be submitted for each purge.

    2. Input Parameters

    The following request parameter list only provides API request parameters. Common request parameters need to be added when the API is called. For more information, refer to Common Request Parameters. The Action field for this API is RefreshCdnUrl.

    Parameter Name Required Type Description
    urls.n Yes String URL to be purged. You may purge multiple URLs


    • You may purge one or multiple URLs. When purging multiple URLs, you can pass parameters like this:

    • Note that URLs must start with "http://" or "https://", otherwise errors will occur;

    • The domain in the submitted purge URL must be a domain that has already been connected to CDN by the user, and whose status is Deploying or Activated; otherwise errors will occur.

    • If there is a parameter in a purge URL, for example:

       > https://www.abc.com/index.php?name=1
       > https://www.abc.com/index.php?name=2

      The parameter will be ignored, and the URL https://www.abc.com/index.php will be purged.

    3. Output Parameters

    Parameter Name Type Description
    code Int Common error code; 0: Succeeded; other values: Failed. For more information, refer to Common Error Codes on Error Code page.
    message String Module error message description depending on API

    data Field Description:

    Parameter Name Type Description

    4. Example

    4.1 Input Example

    > urls.0: https://www.test.com/1.jpg

    4.2 GET Request

    For GET request, all the parameters are required to be appended to the URL:


    4.3 POST Request

    For POST request, the parameters need to be filled in HTTP Request-body. Request address:


    Formats such as form-data and x-www-form-urlencoded are supported for the parameters. The array of parameters is as follows:

    array (
      'Action' => 'RefreshCdnUrl',
      'Timestamp' => 1462864833,
      'Nonce' => 1149033341,
      'urls.0' => 'https://www.test.com/1.jpg'

    When there are too many URLs to be purged, in order to avoid overlength of GET request, it is recommended to use POST method to call this API.
