Functions

func ParseSingleNodeFromNodes added in v0.22.0 

func ParseSingleNodeFromNodes(nodes []*knowledgeobjects.Node) (*knowledgeobjects.Node, error)

Types

type Client 

type Client struct {
	// contains filtered or unexported fields
}

func NewClient 

func NewClient(ctx context.Context, opts ...api.ClientOption) (*Client, error)

NewClient creates a new Identity Knowledge API gRPC Client.

Example (Default)

This example demonstrates how to create a new Identity Knowledge Client. 

package main

import (
	"context"
	"log"

	"github.com/indykite/indykite-sdk-go/knowledge"
)

func main() {
	client, err := knowledge.NewClient(context.Background())
	if err != nil {
		log.Fatalf("failed to create client %v", err)
	}
	_ = client.Close()
}

Example (Options)

This example demonstrates how to create a new Identity Knowledge Client. 

package main

import (
	"context"
	"log"

	api "github.com/indykite/indykite-sdk-go/grpc"
	"github.com/indykite/indykite-sdk-go/knowledge"
)

func main() {
	client, err := knowledge.NewClient(context.Background(),
		api.WithCredentialsJSON([]byte(`{}`)))
	if err != nil {
		log.Fatalf("failed to create client %v", err)
	}
	_ = client.Close()
}

Output:

func NewTestClient 

func NewTestClient(client knowledgepb.IdentityKnowledgeAPIClient) (*Client, error)

NewTestClient creates a new Identity Knowledge gRPC Client.

func (*Client) Close 

func (c *Client) Close() error

Close closes the connection to the API service. The user should invoke this when the client is no longer required.

func (*Client) GetIdentityByID added in v0.22.0 

func (c *Client) GetIdentityByID(
	ctx context.Context,
	id string,
	opts ...grpc.CallOption,
) (*knowledgeobjects.Node, error)

GetIdentityByID is a helper function that queries for a Identity node by its id.

Example

This example demonstrates how to use the Identity Knowledge Client to get an Identity by its id. 

package main

import (
	"context"
	"fmt"
	"log"

	"google.golang.org/protobuf/encoding/protojson"

	"github.com/indykite/indykite-sdk-go/knowledge"
)

func main() {

}

Output:

func (*Client) GetIdentityByIdentifier added in v0.22.0 

func (c *Client) GetIdentityByIdentifier(
	ctx context.Context,
	identifier *Identifier,
	opts ...grpc.CallOption,
) (*knowledgeobjects.Node, error)

GetIdentityByIdentifier is a helper function that queries for a Identity node by its externalID + type combination.

	}()

	response, err := client.GetIdentityByIdentifier(context.Background(), &knowledge.Identifier{
		ExternalID: "1234",
		Type:       "Person",
	},
	)

	if err != nil {
		log.Fatalf("failed to invoke operation on IndyKite Client %v", err)
	}

	"github.com/indykite/indykite-sdk-go/knowledge"
)

func main() {
	client, err := knowledge.NewClient(context.Background())
	if err != nil {
		log.Fatalf("failed to create client %v", err)
	}
	defer func() {
		_ = client.Close()
	}()

	query := "MATCH (n:Person)-[:HAS]->(s:Store) WHERE n.external_id = $external_id"
	params := map[string]*objects.Value{
		"external_id": {
			Type: &objects.Value_StringValue{StringValue: "1234"},
		},
	}
	returns := []*knowledgepb.Return{
		{
			Variable: "n",
		},
	}

	response, err := client.IdentityKnowledgeRead(context.Background(), query, params, returns)
	if err != nil {
		log.Fatalf("failed to invoke operation on IndyKite Client %v", err)
	}
	json := protojson.MarshalOptions{
		Multiline: true,
	}
	fmt.Println(json.Format(response))
}
