Types

type AgentIterator 

type AgentIterator struct {

	// InternalFetch is for use by the Google Cloud Libraries only.
	// It is not part of the stable interface of this package.
	//
	// InternalFetch returns results from a single call to the underlying RPC.
	// The number of results is no greater than pageSize.
	// If there are no more results, nextPageToken is empty and err is nil.
	InternalFetch func(pageSize int, pageToken string) (results []*dialogflowpb.Agent, nextPageToken string, err error)
	// contains filtered or unexported fields
}

AgentIterator manages a stream of *dialogflowpb.Agent.

func (*AgentIterator) Next 

func (it *AgentIterator) Next() (*dialogflowpb.Agent, error)

Next returns the next result. Its second return value is iterator.Done if there are no more results. Once Next returns Done, all subsequent calls will return Done.

func (*AgentIterator) PageInfo 

func (it *AgentIterator) PageInfo() *iterator.PageInfo

PageInfo supports pagination. See the google.golang.org/api/iterator package for details.

type AgentsCallOptions 

type AgentsCallOptions struct {
	GetAgent     []gax.CallOption
	SearchAgents []gax.CallOption
	TrainAgent   []gax.CallOption
	ExportAgent  []gax.CallOption
	ImportAgent  []gax.CallOption
	RestoreAgent []gax.CallOption
}

AgentsCallOptions contains the retry settings for each method of AgentsClient.

type AgentsClient 

type AgentsClient struct {

	// LROClient is used internally to handle longrunning operations.
	// It is exposed so that its CallOptions can be modified if required.
	// Users should not Close this client.
	LROClient *lroauto.OperationsClient

	// The call options for this service.
	CallOptions *AgentsCallOptions
	// contains filtered or unexported fields
}

AgentsClient is a client for interacting with Dialogflow API.

Methods, except Close, may be called concurrently. However, fields must not be modified concurrently with method calls.

func NewAgentsClient 

func NewAgentsClient(ctx context.Context, opts ...option.ClientOption) (*AgentsClient, error)

NewAgentsClient creates a new agents client.

Agents are best described as Natural Language Understanding (NLU) modules that transform user requests into actionable data. You can include agents in your app, product, or service to determine user intent and respond to the user in a natural way.

After you create an agent, you can add [Intents][google.cloud.dialogflow.v2.Intents], [Contexts][google.cloud.dialogflow.v2.Contexts], [Entity Types][google.cloud.dialogflow.v2.EntityTypes], [Webhooks][google.cloud.dialogflow.v2.WebhookRequest], and so on to manage the flow of a conversation and match user input to predefined intents and actions.

You can create an agent using both Dialogflow Standard Edition and Dialogflow Enterprise Edition. For details, see Dialogflow Editions (at /dialogflow-enterprise/docs/editions).

You can save your agent for backup or versioning by exporting the agent by using the [ExportAgent][google.cloud.dialogflow.v2.Agents.ExportAgent] method. You can import a saved agent by using the [ImportAgent][google.cloud.dialogflow.v2.Agents.ImportAgent] method.

Dialogflow provides several prebuilt agents (at https://dialogflow.com/docs/prebuilt-agents) for common conversation scenarios such as determining a date and time, converting currency, and so on.

For more information about agents, see the Dialogflow documentation (at https://dialogflow.com/docs/agents).

Example 
ctx := context.Background()
c, err := dialogflow.NewAgentsClient(ctx)
if err != nil {
	// TODO: Handle error.
}
// TODO: Use client.
_ = c

Output:

func (*AgentsClient) Close 

func (c *AgentsClient) Close() error

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

func (*AgentsClient) Connection 

func (c *AgentsClient) Connection() *grpc.ClientConn

Connection returns the client's connection to the API service.

func (*AgentsClient) ExportAgent 

func (c *AgentsClient) ExportAgent(ctx context.Context, req *dialogflowpb.ExportAgentRequest, opts ...gax.CallOption) (*ExportAgentOperation, error)

ExportAgent exports the specified agent to a ZIP file.

}
op, err := c.ExportAgent(ctx, req)
if err != nil {
	// TODO: Handle error.
}

if err != nil {
	// TODO: Handle error.
}
// TODO: Use resp.
_ = resp

Output:

func (*AgentsClient) ExportAgentOperation 

func (c *AgentsClient) ExportAgentOperation(name string) *ExportAgentOperation

ExportAgentOperation returns a new ExportAgentOperation from a given name. The name must be that of a previously created ExportAgentOperation, possibly from a different process.

func (*AgentsClient) GetAgent 

func (c *AgentsClient) GetAgent(ctx context.Context, req *dialogflowpb.GetAgentRequest, opts ...gax.CallOption) (*dialogflowpb.Agent, error)

GetAgent retrieves the specified agent.

Uploads new intents and entity types without deleting the existing ones. Intents and entity types with the same name are replaced with the new versions from ImportAgentRequest.

Operation <response: [google.protobuf.Empty][google.protobuf.Empty], metadata: [google.protobuf.Struct][google.protobuf.Struct]>

Example 
ctx := context.Background()
c, err := dialogflow.NewAgentsClient(ctx)
if err != nil {
	// TODO: Handle error.
}

req := &dialogflowpb.ImportAgentRequest{
	// TODO: Fill request struct fields.
}

func (*AgentsClient) SearchAgents 

func (c *AgentsClient) SearchAgents(ctx context.Context, req *dialogflowpb.SearchAgentsRequest, opts ...gax.CallOption) *AgentIterator

SearchAgents returns the list of agents.

Since there is at most one conversational agent per project, this method is useful primarily for listing all agents across projects the caller has access to. One can achieve that with a wildcard project collection id "-". Refer to List Sub-Collections (at https://cloud.google.com/apis/design/design_patterns#list_sub-collections).

Example 
ctx := context.Background()
c, err := dialogflow.NewAgentsClient(ctx)
if err != nil {
	// TODO: Handle error.
}

req := &dialogflowpb.SearchAgentsRequest{
	// TODO: Fill request struct fields.
}

		// TODO: Handle error.
	}
	// TODO: Use resp.
	_ = resp
}

func NewContextsClient 

func NewContextsClient(ctx context.Context, opts ...option.ClientOption) (*ContextsClient, error)

NewContextsClient creates a new contexts client.

A context represents additional information included with user input or with an intent returned by the Dialogflow API. Contexts are helpful for differentiating user input which may be vague or have a different meaning depending on additional details from your application such as user setting and preferences, previous user input, where the user is in your application, geographic location, and so on.

You can include contexts as input parameters of a [DetectIntent][google.cloud.dialogflow.v2.Sessions.DetectIntent] (or [StreamingDetectIntent][google.cloud.dialogflow.v2.Sessions.StreamingDetectIntent]) request, or as output contexts included in the returned intent. Contexts expire when an intent is matched, after the number of DetectIntent requests specified by the lifespan_count parameter, or after 10 minutes if no intents are matched for a DetectIntent request.

For more information about contexts, see the Dialogflow documentation (at https://dialogflow.com/docs/contexts).

func NewEntityTypesClient 

func NewEntityTypesClient(ctx context.Context, opts ...option.ClientOption) (*EntityTypesClient, error)

NewEntityTypesClient creates a new entity types client.

Entities are extracted from user input and represent parameters that are meaningful to your application. For example, a date range, a proper name such as a geographic location or landmark, and so on. Entities represent actionable data for your application.

When you define an entity, you can also include synonyms that all map to that entity. For example, "soft drink", "soda", "pop", and so on.

There are three types of entities:

  • **System** - entities that are defined by the Dialogflow API for common data types such as date, time, currency, and so on. A system entity is represented by the `EntityType` type.
  • **Developer** - entities that are defined by you that represent actionable data that is meaningful to your application. For example, you could define a `pizza.sauce` entity for red or white pizza sauce, a `pizza.cheese` entity for the different types of cheese on a pizza, a `pizza.topping` entity for different toppings, and so on. A developer entity is represented by the `EntityType` type.
  • **User** - entities that are built for an individual user such as favorites, preferences, playlists, and so on. A user entity is represented by the [SessionEntityType][google.cloud.dialogflow.v2.SessionEntityType] type.

For more information about entity types, see the [Dialogflow documentation](https://dialogflow.com/docs/entities).

func NewIntentsClient 

func NewIntentsClient(ctx context.Context, opts ...option.ClientOption) (*IntentsClient, error)

NewIntentsClient creates a new intents client.

An intent represents a mapping between input from a user and an action to be taken by your application. When you pass user input to the [DetectIntent][google.cloud.dialogflow.v2.Sessions.DetectIntent] (or [StreamingDetectIntent][google.cloud.dialogflow.v2.Sessions.StreamingDetectIntent]) method, the Dialogflow API analyzes the input and searches for a matching intent. If no match is found, the Dialogflow API returns a fallback intent (`is_fallback` = true).

You can provide additional information for the Dialogflow API to use to match user input to an intent by adding the following to your intent.

  • **Contexts** - provide additional context for intent analysis. For example, if an intent is related to an object in your application that plays music, you can provide a context to determine when to match the intent if the user input is “turn it off”. You can include a context that matches the intent when there is previous user input of "play music", and not when there is previous user input of "turn on the light".
  • **Events** - allow for matching an intent by using an event name instead of user input. Your application can provide an event name and related parameters to the Dialogflow API to match an intent. For example, when your application starts, you can send a welcome event with a user name parameter to the Dialogflow API to match an intent with a personalized welcome message for the user.
  • **Training phrases** - provide examples of user input to train the Dialogflow API agent to better match intents.

For more information about intents, see the [Dialogflow documentation](https://dialogflow.com/docs/intents).

ctx := context.Background()
c, err := dialogflow.NewIntentsClient(ctx)
if err != nil {
	// TODO: Handle error.

func (it *SessionEntityTypeIterator) Next() (*dialogflowpb.SessionEntityType, error)

Next returns the next result. Its second return value is iterator.Done if there are no more results. Once Next returns Done, all subsequent calls will return Done.

func (*SessionEntityTypeIterator) PageInfo 

func (it *SessionEntityTypeIterator) PageInfo() *iterator.PageInfo

PageInfo supports pagination. See the google.golang.org/api/iterator package for details.

type SessionEntityTypesCallOptions 

type SessionEntityTypesCallOptions struct {
	ListSessionEntityTypes  []gax.CallOption
	GetSessionEntityType    []gax.CallOption
	CreateSessionEntityType []gax.CallOption
	UpdateSessionEntityType []gax.CallOption
	DeleteSessionEntityType []gax.CallOption
}

SessionEntityTypesCallOptions contains the retry settings for each method of SessionEntityTypesClient.

type SessionEntityTypesClient 

type SessionEntityTypesClient struct {

	// The call options for this service.
	CallOptions *SessionEntityTypesCallOptions
	// contains filtered or unexported fields
}

SessionEntityTypesClient is a client for interacting with Dialogflow API.

Methods, except Close, may be called concurrently. However, fields must not be modified concurrently with method calls.

func NewSessionEntityTypesClient 

func NewSessionEntityTypesClient(ctx context.Context, opts ...option.ClientOption) (*SessionEntityTypesClient, error)

NewSessionEntityTypesClient creates a new session entity types client.

Entities are extracted from user input and represent parameters that are meaningful to your application. For example, a date range, a proper name such as a geographic location or landmark, and so on. Entities represent actionable data for your application.

Session entity types are referred to as **User** entity types and are entities that are built for an individual user such as favorites, preferences, playlists, and so on. You can redefine a session entity type at the session level.

For more information about entity types, see the [Dialogflow documentation](https://dialogflow.com/docs/entities).

Example 
ctx := context.Background()
c, err := dialogflow.NewSessionEntityTypesClient(ctx)
if err != nil {
	// TODO: Handle error.
}
// TODO: Use client.
_ = c

Output:

func (*SessionEntityTypesClient) Close 

func (c *SessionEntityTypesClient) Close() error

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

func (*SessionEntityTypesClient) Connection 

func (c *SessionEntityTypesClient) Connection() *grpc.ClientConn

Connection returns the client's connection to the API service.

func (*SessionEntityTypesClient) CreateSessionEntityType 

func (c *SessionEntityTypesClient) CreateSessionEntityType(ctx context.Context, req *dialogflowpb.CreateSessionEntityTypeRequest, opts ...gax.CallOption) (*dialogflowpb.SessionEntityType, error)

CreateSessionEntityType creates a session entity type.

ctx := context.Background()
c, err := dialogflow.NewSessionEntityTypesClient(ctx)
if err != nil {
	// TODO: Handle error.
}

req := &dialogflowpb.CreateSessionEntityTypeRequest{
	// TODO: Fill request struct fields.
}
resp, err := c.CreateSessionEntityType(ctx, req)
if err != nil {
	// TODO: Handle error.
}
// TODO: Use resp.
_ = resp

Output:

if err != nil {
	// TODO: Handle error.
}

req := &dialogflowpb.DeleteSessionEntityTypeRequest{
	// TODO: Fill request struct fields.
}
err = c.DeleteSessionEntityType(ctx, req)
if err != nil {
	// TODO: Handle error.
}

Output:

if err != nil {
	// TODO: Handle error.
}
// TODO: Use resp.
_ = resp

Output:

func (*SessionEntityTypesClient) ListSessionEntityTypes 

func (c *SessionEntityTypesClient) ListSessionEntityTypes(ctx context.Context, req *dialogflowpb.ListSessionEntityTypesRequest, opts ...gax.CallOption) *SessionEntityTypeIterator

ListSessionEntityTypes returns the list of all session entity types in the specified session.

Example 
ctx := context.Background()
c, err := dialogflow.NewSessionEntityTypesClient(ctx)
if err != nil {
	// TODO: Handle error.
}

req := &dialogflowpb.ListSessionEntityTypesRequest{
	// TODO: Fill request struct fields.
}
it := c.ListSessionEntityTypes(ctx, req)
for {
	resp, err := it.Next()
	if err == iterator.Done {
		break
	}
	if err != nil {
		// TODO: Handle error.
	}
	// TODO: Use resp.
	_ = resp
}

Output:

func (*SessionEntityTypesClient) UpdateSessionEntityType 

func (c *SessionEntityTypesClient) UpdateSessionEntityType(ctx context.Context, req *dialogflowpb.UpdateSessionEntityTypeRequest, opts ...gax.CallOption) (*dialogflowpb.SessionEntityType, error)

Example 
ctx := context.Background()
c, err := dialogflow.NewSessionEntityTypesClient(ctx)
if err != nil {
	// TODO: Handle error.
}

req := &dialogflowpb.UpdateSessionEntityTypeRequest{
	// TODO: Fill request struct fields.
}

	// TODO: Handle error.
}
// TODO: Use resp.
_ = resp

Output:

type SessionsCallOptions 

type SessionsCallOptions struct {
	DetectIntent          []gax.CallOption
	StreamingDetectIntent []gax.CallOption
}

SessionsCallOptions contains the retry settings for each method of SessionsClient.

type SessionsClient 

type SessionsClient struct {

	// The call options for this service.
	CallOptions *SessionsCallOptions
	// contains filtered or unexported fields
}

SessionsClient is a client for interacting with Dialogflow API.

Methods, except Close, may be called concurrently. However, fields must not be modified concurrently with method calls.

func NewSessionsClient 

func NewSessionsClient(ctx context.Context, opts ...option.ClientOption) (*SessionsClient, error)

NewSessionsClient creates a new sessions client.

A session represents an interaction with a user. You retrieve user input and pass it to the [DetectIntent][google.cloud.dialogflow.v2.Sessions.DetectIntent] (or [StreamingDetectIntent][google.cloud.dialogflow.v2.Sessions.StreamingDetectIntent]) method to determine user intent and respond.

Example 
ctx := context.Background()
c, err := dialogflow.NewSessionsClient(ctx)
if err != nil {
	// TODO: Handle error.
}
// TODO: Use client.
_ = c

Output:

func (*SessionsClient) Close 

func (c *SessionsClient) Close() error

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

func (*SessionsClient) Connection 

func (c *SessionsClient) Connection() *grpc.ClientConn

Connection returns the client's connection to the API service.

func (*SessionsClient) DetectIntent 

func (c *SessionsClient) DetectIntent(ctx context.Context, req *dialogflowpb.DetectIntentRequest, opts ...gax.CallOption) (*dialogflowpb.DetectIntentResponse, error)

DetectIntent processes a natural language query and returns structured, actionable data as a result. This method is not idempotent, because it may cause contexts and session entity types to be updated, which in turn might affect results of future queries.

Example 
ctx := context.Background()
c, err := dialogflow.NewSessionsClient(ctx)
if err != nil {
	// TODO: Handle error.
}

req := &dialogflowpb.DetectIntentRequest{
	// TODO: Fill request struct fields.
}
resp, err := c.DetectIntent(ctx, req)
if err != nil {
	// TODO: Handle error.
}
// TODO: Use resp.
_ = resp

Output:

func (*SessionsClient) StreamingDetectIntent 

func (c *SessionsClient) StreamingDetectIntent(ctx context.Context, opts ...gax.CallOption) (dialogflowpb.Sessions_StreamingDetectIntentClient, error)

StreamingDetectIntent processes a natural language query in audio format in a streaming fashion and returns structured, actionable data as a result. This method is only available via the gRPC API (not REST).

Example 
ctx := context.Background()
c, err := dialogflow.NewSessionsClient(ctx)
if err != nil {
	// TODO: Handle error.
}
stream, err := c.StreamingDetectIntent(ctx)
if err != nil {
	// TODO: Handle error.
}
go func() {
	reqs := []*dialogflowpb.StreamingDetectIntentRequest{
		// TODO: Create requests.
	}
	for _, req := range reqs {
		if err := stream.Send(req); err != nil {
			// TODO: Handle error.
		}
	}
	stream.CloseSend()
}()
for {
	resp, err := stream.Recv()
	if err == io.EOF {
		break
	}
	if err != nil {
		// TODO: handle error.
	}
	// TODO: Use resp.
	_ = resp
}

Output:

type TrainAgentOperation 

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

TrainAgentOperation manages a long-running operation from TrainAgent.

func (*TrainAgentOperation) Done 

func (op *TrainAgentOperation) Done() bool

Done reports whether the long-running operation has completed.

func (*TrainAgentOperation) Metadata 

func (op *TrainAgentOperation) Metadata() (*structpbpb.Struct, error)

Metadata returns metadata associated with the long-running operation. Metadata itself does not contact the server, but Poll does. To get the latest metadata, call this method after a successful call to Poll. If the metadata is not available, the returned metadata and error are both nil.

func (*TrainAgentOperation) Name 

func (op *TrainAgentOperation) Name() string

Name returns the name of the long-running operation. The name is assigned by the server and is unique within the service from which the operation is created.

func (*TrainAgentOperation) Poll 

func (op *TrainAgentOperation) Poll(ctx context.Context, opts ...gax.CallOption) error

Poll fetches the latest state of the long-running operation.

Poll also fetches the latest metadata, which can be retrieved by Metadata.

If Poll fails, the error is returned and op is unmodified. If Poll succeeds and the operation has completed with failure, the error is returned and op.Done will return true. If Poll succeeds and the operation has completed successfully, op.Done will return true.

func (*TrainAgentOperation) Wait 

func (op *TrainAgentOperation) Wait(ctx context.Context, opts ...gax.CallOption) error

Wait blocks until the long-running operation is completed, returning any error encountered.

See documentation of Poll for error-handling information.
