This is a legacy API which has been hidden and will no longer be updated. We recommend using the new SQL Server API 3.0 which is standardized and faster.
The final request URL consists of the following parts:
1) Request domain name: the domain name of the DescribeInstances request is cvm.api.qcloud.com. The actual request domain name varies with the module to which the API belongs. For details, refer to the description of each API.
2) Request path: The request path for the cloud API is "/v2/index.php".
3) Final request parameter strings: Includes both common request parameters and API request parameters.
The combination rule for final request parameter strings is:
https:// + Request method + Request server + Request path + ? + Request string
Therefore, we get the following final request URL, where the first six parameters are common request parameters, the other six parameters are API request parameters.
https://cvm.api.qcloud.com/v2/index.php? Action=DescribeInstances &SecretId=xxxxxxx &Region=gz &Timestamp=1465055529 &Nonce=59485 &Signature=mysignature &InstanceIds.0=ins-0hm4gvho &InstanceIds.1=ins-8oby8q00
