Supports request communication via HTTP or HTTPS channels. HTTPS is recommended because it provides higher security.
Supports sending request via HTTP GET. In this mode, the request parameter has to be included in the request URL.
Each request must specify the operation to be executed, that is, the Action parameter (for example, CreateCluster), and each operation must contain the public request parameters and the specific request parameters of the specified operation.
Both requests and returned results are encoded using the UTF-8 character set.
