Functions

func NewAuthorizationInterceptorProvider

func NewAuthorizationInterceptorProvider(tokenProviders ...TokenProvider) func(string) connect.UnaryInterceptorFunc

NewAuthorizationInterceptorProvider returns a new provider function which, when invoked, returns an interceptor which will set the auth token into the request header by the provided option.

Note that the interceptor returned from this provider is always applied LAST in the series of interceptors added to a client.

func NewCLIWarningInterceptor

func NewCLIWarningInterceptor(container applog.Container) connect.UnaryInterceptorFunc

NewCLIWarningInterceptor returns a new Connect Interceptor that logs CLI warnings returned by server responses.

func NewSetCLIVersionInterceptor

func NewSetCLIVersionInterceptor(version string) connect.UnaryInterceptorFunc

NewSetCLIVersionInterceptor returns a new Connect Interceptor that sets the Buf CLI version into all request headers

Types

type AuthError

type AuthError struct {
	// contains filtered or unexported fields
}

AuthError wraps the error returned in the auth provider to add additional context.

func AsAuthError

func AsAuthError(err error) (*AuthError, bool)

AsAuthError uses errors.As to unwrap any error and look for an *AuthError.

func (*AuthError) Error

func (e *AuthError) Error() string

Error implements the error interface and returns the error message.

func (*AuthError) TokenEnvKey

func (e *AuthError) TokenEnvKey() string

TokenEnvKey returns the environment variable used, if any, for authentication.

func (*AuthError) Unwrap

func (e *AuthError) Unwrap() error

Unwrap returns the underlying error.

type TokenProvider

type TokenProvider interface {
	// RemoteToken returns the remote token from the remote address.
	RemoteToken(address string) string
	// IsFromEnvVar returns true if the TokenProvider is generated from an environment variable.
	IsFromEnvVar() bool
}

TokenProvider finds the token for NewAuthorizationInterceptorProvider.

func NewNetrcTokenProvider

func NewNetrcTokenProvider(container app.EnvContainer, getMachineForName func(app.EnvContainer, string) (netrc.Machine, error)) TokenProvider

NewNetrcTokenProvider returns a TokenProvider for a .netrc in a container.

func NewTokenProviderFromContainer

func NewTokenProviderFromContainer(container app.EnvContainer) (TokenProvider, error)

NewTokenProviderFromContainer creates a singleTokenProvider from the BUF_TOKEN environment variable

func NewTokenProviderFromString

func NewTokenProviderFromString(token string) (TokenProvider, error)

NewTokenProviderFromString creates a singleTokenProvider by the token provided
