Deprecated. Use SuccessFn and CreateErrFn instead.

type FirebaseError

type FirebaseError struct {
	Code   string
	String string

FirebaseError is an error type containing an error code string.

func Error

func Error(code string, msg string) *FirebaseError

type HTTPClient

type HTTPClient struct {
	Client      *http.Client
	RetryConfig *RetryConfig
	ErrParser   ErrorParser // Deprecated. Use CreateErrFn instead.
	CreateErrFn CreateErrFn
	SuccessFn   SuccessFn
	Opts        []HTTPOption

HTTPClient is a convenient API to make HTTP calls.

This API handles repetitive tasks such as entity serialization and deserialization when making HTTP calls. It provides a convenient mechanism to set headers and query parameters on outgoing requests, while enforcing that an explicit context is used per request. Responses returned by HTTPClient can be easily unmarshalled as JSON.

HTTPClient also handles automatically retrying failed HTTP requests.

func NewHTTPClient

func NewHTTPClient(ctx context.Context, opts ...option.ClientOption) (*HTTPClient, string, error)

NewHTTPClient creates a new HTTPClient using the provided client options and the default RetryConfig.

NewHTTPClient returns the created HTTPClient along with the target endpoint URL. The endpoint is obtained from the client options passed into the function.

func WithDefaultRetryConfig

func WithDefaultRetryConfig(hc *http.Client) *HTTPClient

WithDefaultRetryConfig creates a new HTTPClient using the provided client and the default RetryConfig.

The default RetryConfig retries requests on all low-level network errors as well as on HTTP InternalServerError (500) and ServiceUnavailable (503) errors. Repeatedly failing requests are retried up to 4 times with exponential backoff. Retry delay is never longer than 2 minutes.

func (*HTTPClient) Do

func (c *HTTPClient) Do(ctx context.Context, req *Request) (*Response, error)

Do executes the given Request, and returns a Response.

If a RetryConfig is specified on the client, Do attempts to retry failing requests.

If SuccessFn is set on the client or on the request, the response is validated against that function. If this validation fails, returns an error. These errors are created using the CreateErrFn on the client or on the request. If neither is set, CreatePlatformError is used as the default error function.

func (*HTTPClient) DoAndUnmarshal

func (c *HTTPClient) DoAndUnmarshal(ctx context.Context, req *Request, v interface{}) (*Response, error)

DoAndUnmarshal behaves similar to Do, but additionally unmarshals the response payload into the given pointer.

Unmarshal takes place only if the response does not represent an error (as determined by the Do function) and v is not nil. If the unmarshal fails, an error is returned even if the original response indicated success.

type HTTPEntity

type HTTPEntity interface {
	Bytes() ([]byte, error)
	Mime() string

HTTPEntity represents a payload that can be included in an outgoing HTTP request.

func NewJSONEntity

func NewJSONEntity(v interface{}) HTTPEntity

NewJSONEntity creates a new HTTPEntity that will be serialized into JSON.

type HTTPOption

type HTTPOption func(*http.Request)

HTTPOption is an additional parameter that can be specified to customize an outgoing request.

func WithHeader

func WithHeader(key, value string) HTTPOption

WithHeader creates an HTTPOption that will set an HTTP header on the request.

func WithQueryParam

func WithQueryParam(key, value string) HTTPOption

WithQueryParam creates an HTTPOption that will set a query parameter on the request.

func WithQueryParams

func WithQueryParams(qp map[string]string) HTTPOption

WithQueryParams creates an HTTPOption that will set all the entries of qp as query parameters on the request.

type HashConfig

type HashConfig map[string]interface{}

HashConfig represents a hash algorithm configuration used to generate password hashes.

type InstanceIDConfig

type InstanceIDConfig struct {
	Opts      []option.ClientOption
	ProjectID string

InstanceIDConfig represents the configuration of Firebase Instance ID service.

type MessagingConfig

type MessagingConfig struct {
	Opts      []option.ClientOption
	ProjectID string
	Version   string

MessagingConfig represents the configuration of Firebase Cloud Messaging service.

type MockClock

type MockClock struct {
	Timestamp time.Time

MockClock can be used to mock current time during tests.

func (*MockClock) Now

func (m *MockClock) Now() time.Time

Now returns the timestamp set in the MockClock.

type MockTokenSource

type MockTokenSource struct {
	AccessToken string

MockTokenSource is a TokenSource implementation that can be used for testing.

func (*MockTokenSource) Token

func (ts *MockTokenSource) Token() (*oauth2.Token, error)

Token returns the test token associated with the TokenSource.

type Request

type Request struct {
	Method      string
	URL         string
	Body        HTTPEntity
	Opts        []HTTPOption
	SuccessFn   SuccessFn
	CreateErrFn CreateErrFn

Request contains all the parameters required to construct an outgoing HTTP request.

type Response

type Response struct {
	Status int
	Header http.Header
	Body   []byte
	// contains filtered or unexported fields

Response contains information extracted from an HTTP response.

func (*Response) CheckStatus

func (r *Response) CheckStatus(want int) error

CheckStatus checks whether the Response status code has the given HTTP status code.

Returns an error if the status code does not match. If an ErrorParser is specified, uses that to construct the returned error message. Otherwise includes the full response body in the error.

Deprecated. Directly verify the Status field on the Response instead.

func (*Response) Unmarshal

func (r *Response) Unmarshal(want int, v interface{}) error

Unmarshal checks if the Response has the given HTTP status code, and if so unmarshals the response body into the variable pointed by v.

Unmarshal uses internally, and hence v has the same requirements as the json package.

Deprecated. Use DoAndUnmarshal function instead.

type RetryCondition

type RetryCondition func(resp *http.Response, networkErr error) bool

RetryCondition determines if an HTTP request should be retried depending on its last outcome.

type RetryConfig

type RetryConfig struct {
	MaxRetries       int
	CheckForRetry    RetryCondition
	ExpBackoffFactor float64
	MaxDelay         *time.Duration

RetryConfig specifies how the HTTPClient should retry failing HTTP requests.

A request is never retried more than MaxRetries times. If CheckForRetry is nil, all network errors, and all 400+ HTTP status codes are retried. If an HTTP error response contains the Retry-After header, it is always respected. Otherwise retries are delayed with exponential backoff. Set ExpBackoffFactor to 0 to disable exponential backoff, and retry immediately after each error.

If MaxDelay is set, retries delay gets capped by that value. If the Retry-After header requires a longer delay than MaxDelay, retries are not attempted.

type StorageConfig

type StorageConfig struct {
	Opts   []option.ClientOption
	Bucket string

StorageConfig represents the configuration of Google Cloud Storage service.

type SuccessFn

type SuccessFn func(r *Response) bool

SuccessFn is a function that checks if a Response indicates success.
