Client is the interface for the Firebase Cloud Messaging (FCM) service.

func NewClient 

func NewClient(ctx context.Context, c *internal.MessagingConfig) (*Client, error)

NewClient creates a new instance of the Firebase Cloud Messaging Client.

This function can only be invoked from within the SDK. Client applications should access the the messaging service through firebase.App.

func (Client) Send 

func (c Client) Send(ctx context.Context, message *Message) (string, error)

Send sends a Message to Firebase Cloud Messaging.

The Message must specify exactly one of Token, Topic and Condition fields. FCM will customize the message for each target platform based on the arguments specified in the Message.

func (Client) SendAll deprecated 

func (c Client) SendAll(ctx context.Context, messages []*Message) (*BatchResponse, error)

SendAll sends the messages in the given array via Firebase Cloud Messaging.

The messages array may contain up to 500 messages. SendAll employs batching to send the entire array of messages as a single RPC call. Compared to the Send() function, this is a significantly more efficient way to send multiple messages. The responses list obtained from the return value corresponds to the order of the input messages. An error from SendAll indicates a total failure, meaning that none of the messages in the array could be sent. Partial failures are indicated by a BatchResponse return value.

Deprecated: Use SendEach instead.

func (Client) SendAllDryRun deprecated 

func (c Client) SendAllDryRun(ctx context.Context, messages []*Message) (*BatchResponse, error)

SendAllDryRun sends the messages in the given array via Firebase Cloud Messaging in the dry run (validation only) mode.

This function does not actually deliver any messages to target devices. Instead, it performs all the SDK-level and backend validations on the messages, and emulates the send operation.

The messages array may contain up to 500 messages. SendAllDryRun employs batching to send the entire array of messages as a single RPC call. Compared to the SendDryRun() function, this is a significantly more efficient way to validate sending multiple messages. The responses list obtained from the return value corresponds to the order of the input messages. An error from SendAllDryRun indicates a total failure, meaning that none of the messages in the array could be sent for validation. Partial failures are indicated by a BatchResponse return value.

Deprecated: Use SendEachDryRun instead.

func (Client) SendDryRun 

func (c Client) SendDryRun(ctx context.Context, message *Message) (string, error)

The responses list obtained from the return value corresponds to the order of the input messages. An error from SendEach or a BatchResponse with all failures indicates a total failure, meaning that none of the messages in the list could be sent. Partial failures or no failures are only indicated by a BatchResponse return value.

func (Client) SendEachDryRun added in v4.12.0 

func (c Client) SendEachDryRun(ctx context.Context, messages []*Message) (*BatchResponse, error)

This function does not actually deliver any messages to target devices. Instead, it performs all the SDK-level and backend validations on the messages, and emulates the send operation.

The messages array may contain up to 500 messages. Unlike SendAllDryRun(), SendEachDryRun sends the entire array of messages by making a single HTTP call for each message. The responses list obtained from the return value corresponds to the order of the input messages. An error from SendEachDryRun or a BatchResponse with all failures indicates a total failure, meaning that none of the messages in the list could be sent. Partial failures or no failures are only indicated by a BatchResponse return value.

func (c Client) SendEachForMulticast(ctx context.Context, message *MulticastMessage) (*BatchResponse, error)

SendEachForMulticast sends the given multicast message to all the FCM registration tokens specified.

The tokens array in MulticastMessage may contain up to 500 tokens. SendMulticast uses the SendEach() function to send the given message to all the target recipients. The responses list obtained from the return value corresponds to the order of the input tokens. An error from SendEachForMulticast or a BatchResponse with all failures indicates a total failure, meaning that none of the messages in the list could be sent. Partial failures or no failures are only indicated by a BatchResponse return value.

func (Client) SendEachForMulticastDryRun added in v4.12.0 

func (c Client) SendEachForMulticastDryRun(ctx context.Context, message *MulticastMessage) (*BatchResponse, error)

The tokens array in MulticastMessage may contain up to 500 tokens. SendEachForMulticastDryRunn uses the SendEachDryRun() function to send the given message. The responses list obtained from the return value corresponds to the order of the input tokens. An error from SendEachForMulticastDryRun or a BatchResponse with all failures indicates a total failure, meaning that of the messages in the list could be sent. Partial failures or no failures are only indicated by a BatchResponse return value.

func (Client) SendMulticast deprecated 

func (c Client) SendMulticast(ctx context.Context, message *MulticastMessage) (*BatchResponse, error)

SendMulticast sends the given multicast message to all the FCM registration tokens specified.

The responses list obtained from the return value corresponds to the order of the input tokens. An error from SendMulticast indicates a total failure, meaning that the message could not be sent to any of the recipients. Partial failures are indicated by a BatchResponse return value.

Deprecated: Use SendEachForMulticast instead.

func (Client) SendMulticastDryRun deprecated 

func (c Client) SendMulticastDryRun(ctx context.Context, message *MulticastMessage) (*BatchResponse, error)

SendMulticastDryRun sends the given multicast message to all the specified FCM registration tokens in the dry run (validation only) mode.

This function does not actually deliver any messages to target devices. Instead, it performs all the SDK-level and backend validations on the messages, and emulates the send operation.

The tokens array in MulticastMessage may contain up to 500 tokens. SendMulticastDryRun uses the SendAllDryRun() function to send the given message. The responses list obtained from the return value corresponds to the order of the input tokens. An error from SendMulticastDryRun indicates a total failure, meaning that none of the messages were sent to FCM for validation. Partial failures are indicated by a BatchResponse return value.
