LookupServiceClient - Documentation

Constructor

new LookupServiceClient(optionsopt, gaxInstanceopt)

Construct an instance of LookupServiceClient.

Parameters:

Name Type Attributes Description

options

object

The configuration object. The options accepted by the constructor are described in detail in this document. The common options are:

Properties

Name Type Attributes Description

credentials

object

Credentials object.

Properties

Name	Type	Attributes	Description
`client_email`	string	<optional>
`private_key`	string	<optional>

email

string

Account email address. Required when using a .pem or .p12 keyFilename.

keyFilename

string

Full path to the a .json, .pem, or .p12 key downloaded from the Google Developers Console. If you provide a path to a JSON file, the projectId option below is not necessary. NOTE: .pem and .p12 require you to specify options.email as well.

port

number

The port on which to connect to the remote host.

projectId

string

The project ID from the Google Developer's Console, e.g. 'grape-spaceship-123'. We will also check the environment variable GCLOUD_PROJECT for your project ID. If your app is running in an environment which supports Application Default Credentials, your project ID will be detected automatically.

apiEndpoint

string

The domain name of the API remote host.

clientConfig

gax.ClientConfig

Client configuration override. Follows the structure of gapicConfig.

fallback

boolean

Use HTTP/1.1 REST mode. For more information, please check the documentation.

gaxInstance

gax

loaded instance of google-gax. Useful if you need to avoid loading the default gRPC version and want to use the fallback HTTP implementation. Load only fallback version and pass it to the constructor: const gax = require('google-gax/build/src/fallback'); // avoids loading google-gax with gRPC const client = new LookupServiceClient({fallback: true}, gax);

Members

apiEndpoint

The DNS address for this API service.

apiEndpoint

The DNS address for this API service - same as servicePath.

port

The port for this API service.

scopes

The scopes needed to make gRPC calls for every method defined in this service.

servicePath

The DNS address for this API service.

Methods

close() → {Promise}

Terminate the gRPC channel and close the client.

The client will no longer be usable and all future behavior is undefined.

Returns:

Type	Description
Promise	A promise that resolves when the client is closed.

endpointPath(project, location, namespace, service, endpoint) → {string}

Return a fully-qualified endpoint resource name string.

Parameters:

Name	Type	Description
`project`	string
`location`	string
`namespace`	string
`service`	string
`endpoint`	string

Returns:

Type	Description
string	Resource name string.

getLocation(request, optionsopt) → {Promise}

Gets information about a location.

Parameters:

Name Type Attributes Description

request

Object

The request object that will be sent.

Properties

Name	Type	Description
`name`	string	Resource name for the location.

options

object

Call options. See CallOptions for more details.

Returns:

Type	Description
Promise	The promise which resolves to an array. The first element of the array is an object representing Location. Please see the documentation for more details and examples.

Example

```
const [response] = await client.getLocation(request);
```

getProjectId() → {Promise}

Return the project ID used by this class.

Returns:

Type	Description
Promise	A promise that resolves to string containing the project ID.

initialize() → {Promise}

Initialize the client. Performs asynchronous operations (such as authentication) and prepares the client. This function will be called automatically when any class method is called for the first time, but if you need to initialize it before calling an actual method, feel free to call initialize() directly.

You can await on this method if you want to make sure the client is initialized.

Returns:

Type	Description
Promise	A promise that resolves to an authenticated service stub.

listLocationsAsync(request, optionsopt) → {Object}

Lists information about the supported locations for this service. Returns an iterable object.

for-await-of syntax is used with the iterable to get response elements on-demand.

Parameters:

Name Type Attributes Description

request

Object

The request object that will be sent.

Properties

Name	Type	Description
`name`	string	The resource that owns the locations collection, if applicable.
`filter`	string	The standard list filter.
`pageSize`	number	The standard list page size.
`pageToken`	string	The standard list page token.

options

object

Call options. See CallOptions for more details.

Returns:

Type	Description
Object	An iterable Object that allows async iteration. When you iterate the returned iterable, each element will be an object representing Location. The API will be called under the hood as needed, once per the page, so you can stop the iteration when you don't need more results. Please see the documentation for more details and examples.

Example

```
const iterable = client.listLocationsAsync(request);
for await (const response of iterable) {
  // process response
}
```
