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
Links	SDK Dependency Go SDK User Guide

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

package main
 
import (
    "fmt"
    "github.com/huaweicloud/huaweicloud-sdk-go-v3/core/auth/basic"
    functiongraph "github.com/huaweicloud/huaweicloud-sdk-go-v3/services/functiongraph/v2"
    "github.com/huaweicloud/huaweicloud-sdk-go-v3/services/functiongraph/v2/model"
    region "github.com/huaweicloud/huaweicloud-sdk-go-v3/services/functiongraph/v2/region"
)

func main() {
    // This example is only used for testing purposes. Do not hardcode your AK/SK in the production environment.
    ak := "<YOUR AK>"
    sk := "<YOUR SK>"
    securityToken := os.Getenv("HUAWEICLOUD_SDK_SECURITY_TOKEN")
    projectId := "{your projectId string}"
 
    auth := basic.NewCredentialsBuilder().
        WithAk(ak).
        WithSk(sk).
        WithSecurityToken(securityToken).
        WithProjectId(projectId).
        SafeBuild()
 
    client := functiongraph.NewFunctionGraphClient(
        functiongraph.FunctionGraphClientBuilder().
            WithRegion(region.ValueOf("<region>")).
            WithCredential(auth).
            Build())
 
request := &model.InvokeFunctionRequest{}
xCffLogTypeRequest:= "tail"
request.XCffLogType = &xCffLogTypeRequest
xCFFRequestVersionRequest:= "v1"
request.XCFFRequestVersion = &xCFFRequestVersionRequest
request.FunctionUrn = "urn:fss:<region>:<project_id>:function:default:<func_name>:<version>"
    response, err := client.InvokeFunction(request)
    if err == nil {
        fmt.Printf("%+v\n", response)
    } else {
        fmt.Println(err)
    }
}

NOTE:

Obtain AK/SK, region (endpoint), and project_id by referring to AK/SK Signing and Authentication Guide.

Obtain func_name and version from the function details page.

xCFFRequestVersionRequest indicates the response body format. v0: text format; v1: JSON format. Select this format when using an SDK.
