Overview

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, Contexts, Entity Types, Webhooks, 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.

You can save your agent for backup or versioning by exporting the agent by using the ExportAgent method. You can import a saved agent by using the ImportAgent method.

Dialogflow provides several 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.

Constructor Details

#initialize(credentials: nil, scopes: ALL_SCOPES, client_config: {}, timeout: DEFAULT_TIMEOUT, metadata: nil, exception_transformer: nil, lib_name: nil, lib_version: "") ⇒ AgentsClient

Returns a new instance of AgentsClient

Parameters:

  • credentials (Google::Auth::Credentials, String, Hash, GRPC::Core::Channel, GRPC::Core::ChannelCredentials, Proc) —

    Provides the means for authenticating requests made by the client. This parameter can be many types. A Google::Auth::Credentials uses a the properties of its represented keyfile for authenticating requests made by this client. A String will be treated as the path to the keyfile to be used for the construction of credentials for this client. A Hash will be treated as the contents of a keyfile to be used for the construction of credentials for this client. A GRPC::Core::Channel will be used to make calls through. A GRPC::Core::ChannelCredentials for the setting up the RPC client. The channel credentials should already be composed with a GRPC::Core::CallCredentials object. A Proc will be used as an updater_proc for the Grpc channel. The proc transforms the metadata for requests, generally, to give OAuth credentials.

  • scopes (Array<String>) —

    The OAuth scopes for this service. This parameter is ignored if an updater_proc is supplied.

  • client_config (Hash) —

    A Hash for call options for each method. See Google::Gax#construct_settings for the structure of this data. Falls back to the default config if not specified or the specified config is missing data points.

  • timeout (Numeric) —

    The default timeout, in seconds, for calls made through this client.

  • metadata (Hash) —

    Default metadata to be sent with each request. This can be overridden on a per call basis.

  • exception_transformer (Proc) —

    An optional proc that intercepts any exceptions raised during an API call to inject custom error handling.

#restore_agent(parent, agent_uri: nil, agent_content: nil, options: nil) ⇒ Google::Gax::Operation

Restores the specified agent from a ZIP file.

Replaces the current agent version with a new one. All the intents and entity types in the older version are deleted.

Operation Protobuf::Empty, metadata: Protobuf::Struct>

Examples:

require "google/cloud/dialogflow"

agents_client = Google::Cloud::Dialogflow::Agents.new(version: :v2)
formatted_parent = Google::Cloud::Dialogflow::V2::AgentsClient.project_path("[PROJECT]")

# Register a callback during the method call.
operation = agents_client.restore_agent(formatted_parent) do |op|
  raise op.results.message if op.error?
  op_results = op.results
  # Process the results.

  metadata = op.metadata
  # Process the metadata.
end

# Or use the return value to register a callback.
operation.on_done do |op|
  raise op.results.message if op.error?
  op_results = op.results
  # Process the results.

  metadata = op.metadata
  # Process the metadata.
end

# Manually reload the operation.
operation.reload!

# Or block until the operation completes, triggering callbacks on
# completion.
operation.wait_until_done!

Parameters:

  • parent (String) —

    Required. The project that the agent to restore is associated with. Format: +projects/+.

  • agent_uri (String) —

    The URI to a Google Cloud Storage file containing the agent to restore. Note: The URI must start with "gs://".

  • agent_content (String) —

    The agent to restore.

    Example for how to restore an agent via the command line:

    curl \ 'https://dialogflow.googleapis.com/v2/projects//agent:restore\ -X POST \ -H 'Authorization: Bearer '$(gcloud auth print-access-token) \ -H 'Accept: application/json' \ -H 'Content-Type: application/json' \ --compressed \ --data-binary "{ 'agentContent': '$(cat | base64 -w 0)' }" \

  • options (Google::Gax::CallOptions) —

    Overrides the default settings for this call, e.g, timeout, retries, etc.

Returns:

  • (Google::Gax::Operation)

Raises:

  • (Google::Gax::GaxError) —

    if the RPC is aborted.

#search_agents(parent, page_size: nil, options: nil) {|result, operation| ... } ⇒ Google::Gax::PagedEnumerable<Google::Cloud::Dialogflow::V2::Agent>

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.

Examples:

require "google/cloud/dialogflow"

agents_client = Google::Cloud::Dialogflow::Agents.new(version: :v2)
formatted_parent = Google::Cloud::Dialogflow::V2::AgentsClient.project_path("[PROJECT]")

# Iterate over all results.
agents_client.search_agents(formatted_parent).each do |element|
  # Process element.
end

# Or iterate over results one page at a time.
agents_client.search_agents(formatted_parent).each_page do |page|
  # Process each page at a time.
  page.each do |element|
    # Process element.
  end
end

Parameters:

  • parent (String) —

    Required. The project to list agents from. Format: +projects/+.

  • page_size (Integer) —

    The maximum number of resources contained in the underlying API response. If page streaming is performed per-resource, this parameter does not affect the return value. If page streaming is performed per-page, this determines the maximum number of resources in a page.

  • options (Google::Gax::CallOptions) —

    Overrides the default settings for this call, e.g, timeout, retries, etc.

Yields:

  • (result, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Returns:

  • (Google::Gax::PagedEnumerable<Google::Cloud::Dialogflow::V2::Agent>) —

    An enumerable of Google::Cloud::Dialogflow::V2::Agent instances. See Google::Gax::PagedEnumerable documentation for other operations such as per-page iteration or access to the response object.

Raises:

  • (Google::Gax::GaxError) —

    if the RPC is aborted.
