Functions ¶
func IsInternal ¶
IsInternal checks if the given error was due to an internal server error.
func IsInvalidAPNSCredentials ¶
IsInvalidAPNSCredentials checks if the given error was due to invalid APNS certificate or auth key.
func IsInvalidArgument ¶
IsInvalidArgument checks if the given error was due to an invalid argument in the request.
func IsMessageRateExceeded ¶
IsMessageRateExceeded checks if the given error was due to the client exceeding a quota.
func IsMismatchedCredential ¶
IsMismatchedCredential checks if the given error was due to an invalid credential or permission error.
func IsRegistrationTokenNotRegistered ¶
IsRegistrationTokenNotRegistered checks if the given error was due to a registration token that became invalid.
func IsServerUnavailable ¶
IsServerUnavailable checks if the given error was due to the backend server being temporarily unavailable.
func IsTooManyTopics ¶
IsTooManyTopics checks if the given error was due to the client exceeding the allowed number of topics.
Types ¶
type APNSConfig ¶
type APNSConfig struct { Headers map[string]string `json:"headers,omitempty"` Payload *APNSPayload `json:"payload,omitempty"` }
APNSConfig contains messaging options specific to the Apple Push Notification Service (APNS).
See https://developer.apple.com/library/content/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/CommunicatingwithAPNs.html for more details on supported headers and payload keys.
type APNSPayload ¶
APNSPayload is the payload that can be included in an APNS message.
The payload mainly consists of the aps dictionary. Additionally it may contain arbitrary key-values pairs as custom data fields.
See https://developer.apple.com/library/content/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/PayloadKeyReference.html for a full list of supported payload fields.
func (*APNSPayload) MarshalJSON ¶
func (p *APNSPayload) MarshalJSON() ([]byte, error)
MarshalJSON marshals an APNSPayload into JSON (for internal use only).
type AndroidConfig ¶
type AndroidConfig struct { CollapseKey string `json:"collapse_key,omitempty"` Priority string `json:"priority,omitempty"` // one of "normal" or "high" TTL *time.Duration `json:"-"` RestrictedPackageName string `json:"restricted_package_name,omitempty"` Data map[string]string `json:"data,omitempty"` // if specified, overrides the Data field on Message type Notification *AndroidNotification `json:"notification,omitempty"` }
AndroidConfig contains messaging options specific to the Android platform.
func (*AndroidConfig) MarshalJSON ¶
func (a *AndroidConfig) MarshalJSON() ([]byte, error)
MarshalJSON marshals an AndroidConfig into JSON (for internal use only).
type AndroidNotification ¶
type AndroidNotification struct { Title string `json:"title,omitempty"` // if specified, overrides the Title field of the Notification type Body string `json:"body,omitempty"` // if specified, overrides the Body field of the Notification type Icon string `json:"icon,omitempty"` Color string `json:"color,omitempty"` // notification color in #RRGGBB format Sound string `json:"sound,omitempty"` Tag string `json:"tag,omitempty"` ClickAction string `json:"click_action,omitempty"` BodyLocKey string `json:"body_loc_key,omitempty"` BodyLocArgs []string `json:"body_loc_args,omitempty"` TitleLocKey string `json:"title_loc_key,omitempty"` TitleLocArgs []string `json:"title_loc_args,omitempty"` }
AndroidNotification is a notification to send to Android devices.
type Aps ¶
type Aps struct { AlertString string Alert *ApsAlert Badge *int Sound string ContentAvailable bool MutableContent bool Category string ThreadID string CustomData map[string]interface{} }
Aps represents the aps dictionary that may be included in an APNSPayload.
Alert may be specified as a string (via the AlertString field), or as a struct (via the Alert field).
func (*Aps) MarshalJSON ¶
MarshalJSON marshals an Aps into JSON (for internal use only).
type ApsAlert ¶
type ApsAlert struct { Title string `json:"title,omitempty"` // if specified, overrides the Title field of the Notification type Body string `json:"body,omitempty"` // if specified, overrides the Body field of the Notification type LocKey string `json:"loc-key,omitempty"` LocArgs []string `json:"loc-args,omitempty"` TitleLocKey string `json:"title-loc-key,omitempty"` TitleLocArgs []string `json:"title-loc-args,omitempty"` ActionLocKey string `json:"action-loc-key,omitempty"` LaunchImage string `json:"launch-image,omitempty"` }
ApsAlert is the alert payload that can be included in an Aps.
See https://developer.apple.com/library/content/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/PayloadKeyReference.html for supported fields.
type Client ¶
type Client struct {
// contains filtered or unexported fields
}
Client is the interface for the Firebase Cloud Messaging (FCM) service.
func NewClient ¶
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 ¶
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) SendDryRun ¶
SendDryRun sends a Message to Firebase Cloud Messaging in the dry run (validation only) mode.
This function does not actually deliver the message to target devices. Instead, it performs all the SDK-level and backend validations on the message, and emulates the send operation.
func (*Client) SubscribeToTopic ¶
func (c *Client) SubscribeToTopic(ctx context.Context, tokens []string, topic string) (*TopicManagementResponse, error)
SubscribeToTopic subscribes a list of registration tokens to a topic.
The tokens list must not be empty, and have at most 1000 tokens.
func (*Client) UnsubscribeFromTopic ¶
func (c *Client) UnsubscribeFromTopic(ctx context.Context, tokens []string, topic string) (*TopicManagementResponse, error)
UnsubscribeFromTopic unsubscribes a list of registration tokens from a topic.
The tokens list must not be empty, and have at most 1000 tokens.
type Message ¶
type Message struct { Data map[string]string `json:"data,omitempty"` Notification *Notification `json:"notification,omitempty"` Android *AndroidConfig `json:"android,omitempty"` Webpush *WebpushConfig `json:"webpush,omitempty"` APNS *APNSConfig `json:"apns,omitempty"` Token string `json:"token,omitempty"` Topic string `json:"-"` Condition string `json:"condition,omitempty"` }
Message to be sent via Firebase Cloud Messaging.
Message contains payload data, recipient information and platform-specific configuration options. A Message must specify exactly one of Token, Topic or Condition fields. Apart from that a Message may specify any combination of Data, Notification, Android, Webpush and APNS fields. See https://firebase.google.com/docs/reference/fcm/rest/v1/projects.messages for more details on how the backend FCM servers handle different message parameters.
func (*Message) MarshalJSON ¶
MarshalJSON marshals a Message into JSON (for internal use only).
type Notification ¶
type Notification struct { Title string `json:"title,omitempty"` Body string `json:"body,omitempty"` }
Notification is the basic notification template to use across all platforms.
type TopicManagementResponse ¶
TopicManagementResponse is the result produced by topic management operations.
TopicManagementResponse provides an overview of how many input tokens were successfully handled, and how many failed. In case of failures, the Errors list provides specific details concerning each error.
type WebpushConfig ¶
type WebpushConfig struct { Headers map[string]string `json:"headers,omitempty"` Data map[string]string `json:"data,omitempty"` Notification *WebpushNotification `json:"notification,omitempty"` }
WebpushConfig contains messaging options specific to the WebPush protocol.
See https://tools.ietf.org/html/rfc8030#section-5 for additional details, and supported headers.
type WebpushNotification ¶
type WebpushNotification struct { Title string `json:"title,omitempty"` // if specified, overrides the Title field of the Notification type Body string `json:"body,omitempty"` // if specified, overrides the Body field of the Notification type Icon string `json:"icon,omitempty"` }
WebpushNotification is a notification to send via WebPush protocol.
