Final Request Format

Last updated: 2020-06-04 17:50:17

Note:

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

The final request URL is made up of the following elements:

1) Request domain: The request domain for Query List of Instances(DescribeInstances) is cvm.api.qcloud.com. The actual request domain varies depending on the module to which the API belongs. For more information, refer to descriptions of APIs.
2) Request path: The request path of Cloud API is always /v2/index.php.
3) Final request parameter string: By combining common request parameters and API request parameters,

the final format of request URL is as follows:

https:// + request domain name + request path + ? +final request parameter string

The final request URL is as follows. The first six parameters are common request parameters, and the last six ones are API request parameters.
