Go SDK

A synchronous function execution SDK is used as an example. To use the sample code, you must add the SDK dependency with the same language.

**Table 1** Go SDK information
SDK Info	Description
Installation	go get -u github.com/huaweicloud/huaweicloud-sdk-go-v3

The request/response parameters and example requests/responses of the SDK are the same as those of the corresponding APIs. For details about the parameters and examples, see the API for executing a function synchronously.

SDK Request Example
