Overview

Package iot is an auto-generated package for the Cloud IoT API.

Registers and manages IoT (Internet of Things) devices that connect to the Google Cloud Platform.

Example usage

To get started with this package, create a client.

ctx := context.Background()
c, err := iot.NewDeviceManagerClient(ctx)
if err != nil {
	// TODO: Handle error.
}
defer c.Close()

The client will use your default application credentials. Clients should be reused instead of created as needed. The methods of Client are safe for concurrent use by multiple goroutines. The returned client must be Closed when it is done being used.

Using the Client

The following is an example of making an API call with the newly created client.

ctx := context.Background()
c, err := iot.NewDeviceManagerClient(ctx)
if err != nil {
	// TODO: Handle error.
}
defer c.Close()

req := &iotpb.CreateDeviceRegistryRequest{
	// TODO: Fill request struct fields.
	// See https://pkg.go.dev/google.golang.org/genproto/googleapis/cloud/iot/v1#CreateDeviceRegistryRequest.
}
resp, err := c.CreateDeviceRegistry(ctx, req)
if err != nil {
	// TODO: Handle error.
}
// TODO: Use resp.
_ = resp

Use of Context

The ctx passed to NewClient is used for authentication requests and for creating the underlying connection, but is not used for subsequent calls. Individual methods on the client use the ctx given to them.

To close the open connection, use the Close() method.

For information about setting deadlines, reusing contexts, and more please visit https://pkg.go.dev/cloud.google.com/go.

Functions

DefaultAuthScopes reports the default set of authentication scopes to use with this package.

Types

type DeviceIterator

type DeviceIterator struct {

	// Response is the raw response for the current page.
	// It must be cast to the RPC response type.
	// Calling Next() or InternalFetch() updates this value.
	Response interface{}

	// 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 []*iotpb.Device, nextPageToken string, err error)
	// contains filtered or unexported fields
}

DeviceIterator manages a stream of *iotpb.Device.

func (*DeviceIterator) Next

func (it *DeviceIterator) Next() (*iotpb.Device, 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 (*DeviceIterator) PageInfo

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

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

type DeviceManagerCallOptions

type DeviceManagerCallOptions struct {
	CreateDeviceRegistry      []gax.CallOption
	GetDeviceRegistry         []gax.CallOption
	UpdateDeviceRegistry      []gax.CallOption
	DeleteDeviceRegistry      []gax.CallOption
	ListDeviceRegistries      []gax.CallOption
	CreateDevice              []gax.CallOption
	GetDevice                 []gax.CallOption
	UpdateDevice              []gax.CallOption
	DeleteDevice              []gax.CallOption
	ListDevices               []gax.CallOption
	ModifyCloudToDeviceConfig []gax.CallOption
	ListDeviceConfigVersions  []gax.CallOption
	ListDeviceStates          []gax.CallOption
	SetIamPolicy              []gax.CallOption
	GetIamPolicy              []gax.CallOption
	TestIamPermissions        []gax.CallOption
	SendCommandToDevice       []gax.CallOption
	BindDeviceToGateway       []gax.CallOption
	UnbindDeviceFromGateway   []gax.CallOption
}

DeviceManagerCallOptions contains the retry settings for each method of DeviceManagerClient.

type DeviceManagerClient

type DeviceManagerClient struct {

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

DeviceManagerClient is a client for interacting with Cloud IoT API. Methods, except Close, may be called concurrently. However, fields must not be modified concurrently with method calls.

func NewDeviceManagerClient

func NewDeviceManagerClient(ctx context.Context, opts ...option.ClientOption) (*DeviceManagerClient, error)

NewDeviceManagerClient creates a new device manager client based on gRPC. The returned client must be Closed when it is done being used to clean up its underlying connections.

func (*DeviceManagerClient) SendCommandToDevice

SendCommandToDevice sends a command to the specified device. In order for a device to be able to receive commands, it must:

be connected to Cloud IoT Core using the MQTT protocol, and

be subscribed to the group of MQTT topics specified by /devices/{device-id}/commands/#. This subscription will receive commands at the top-level topic /devices/{device-id}/commands as well as commands for subfolders, like /devices/{device-id}/commands/subfolder. Note that subscribing to specific subfolders is not supported. If the command could not be delivered to the device, this method will return an error; in particular, if the device is not subscribed, this method will return FAILED_PRECONDITION. Otherwise, this method will return OK. If the subscription is QoS 1, at least once delivery will be guaranteed; for QoS 0, no acknowledgment will be expected from the device.

package main

import (
	"context"
