Constructor Details

#initialize {|config| ... } ⇒ Client

Create a new LookupService REST client object.

Examples:


# Create a client using the default configuration
client = ::Google::Cloud::ServiceDirectory::V1::LookupService::Rest::Client.new

# Create a client using a custom configuration
client = ::Google::Cloud::ServiceDirectory::V1::LookupService::Rest::Client.new do |config|
  config.timeout = 10.0
end

Yields:

  • (config) —

    Configure the LookupService client.

::Google::Cloud::ServiceDirectory::V1::LookupService::Rest::Client.configure do |config|
  config.timeout = 10.0
end

Yields:

  • (config) —

    Configure the Client client.

Instance Method Details

#configure {|config| ... } ⇒ Client::Configuration

Configure the LookupService Client instance.

The configuration is set to the derived mode, meaning that values can be changed, but structural changes (adding new fields, etc.) are not allowed. Structural changes should be made on configure.

See Configuration for a description of the configuration fields.

Yields:

  • (config) —

    Configure the Client client.

#resolve_service(request, options = nil) ⇒ ::Google::Cloud::ServiceDirectory::V1::ResolveServiceResponse #resolve_service(name: nil, max_endpoints: nil, endpoint_filter: nil) ⇒ ::Google::Cloud::ServiceDirectory::V1::ResolveServiceResponse

Returns a service and its associated endpoints. Resolving a service is not considered an active developer method.

Overloads:

  • #resolve_service(request, options = nil) ⇒ ::Google::Cloud::ServiceDirectory::V1::ResolveServiceResponse

    Pass arguments to resolve_service via a request object, either of type ResolveServiceRequest or an equivalent Hash.

    Parameters:

    • request (::Google::Cloud::ServiceDirectory::V1::ResolveServiceRequest, ::Hash) —

      A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.

    • options (::Gapic::CallOptions, ::Hash) (defaults to: nil) —

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

  • #resolve_service(name: nil, max_endpoints: nil, endpoint_filter: nil) ⇒ ::Google::Cloud::ServiceDirectory::V1::ResolveServiceResponse

    Pass arguments to resolve_service via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

    Parameters:

    • name (::String) (defaults to: nil) —

      Required. The name of the service to resolve.

    • max_endpoints (::Integer) (defaults to: nil) —

      Optional. The maximum number of endpoints to return. Defaults to 25. Maximum is 100. If a value less than one is specified, the Default is used. If a value greater than the Maximum is specified, the Maximum is used.

    • endpoint_filter (::String) (defaults to: nil) —

      Optional. The filter applied to the endpoints of the resolved service.

      General filter string syntax: () can be "name" or "metadata." for map field. can be "<, >, <=, >=, !=, =, :". Of which ":" means HAS and is roughly the same as "=". must be the same data type as the field. can be "AND, OR, NOT".

      Examples of valid filters:

      • "metadata.owner" returns Endpoints that have a label with the key "owner", this is the same as "metadata:owner"
      • "metadata.protocol=gRPC" returns Endpoints that have key/value "protocol=gRPC"
      • "metadata.owner!=sd AND metadata.foo=bar" returns Endpoints that have "owner" field in metadata with a value that is not "sd" AND have the key/value foo=bar.

Yields:

  • (result, operation) —

    Access the result along with the TransportOperation object

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the REST call is aborted.
