Auth

GetAccountID

We offer a convenient way to extract the AccountID field from an incoming authorization token. For this purpose auth.GetAccountID(ctx, nil) function can be used:

func (s *contactsServer) Read(ctx context.Context, req *ReadRequest) (*ReadResponse, error) {
	input := req.GetContact()

	accountID, err := auth.GetAccountID(ctx, nil)
	if err == nil {
		input.AccountId = accountID
	} else if input.GetAccountId() == "" {
		return nil, err
	}

	c, err := DefaultReadContact(ctx, input, s.db)
	if err != nil {
		return nil, err
	}
	return &ReadResponse{Contact: c}, nil
}

When bootstrapping a gRPC server, add middleware that will extract the account_id token from the request context and set it in the request struct. The middleware will have to navigate the request struct via reflection, in the case that the account_id field is nested within the request (like if it's in a request wrapper as per our example above)

Functions

func GetAccountID

func GetAccountID(ctx context.Context, keyfunc jwt.Keyfunc) (string, error)

GetAccountID gets the JWT from a context and returns the AccountID field

func GetJWTField

func GetJWTField(ctx context.Context, tokenField string, keyfunc jwt.Keyfunc) (string, error)

GetJWTField gets the JWT from a context and returns the specified field using the DefaultTokenName

func GetJWTFieldWithTokenType

func GetJWTFieldWithTokenType(ctx context.Context, tokenType, tokenField string, keyfunc jwt.Keyfunc) (string, error)

GetJWTFieldWithTokenType gets the JWT from a context and returns the specified field. The user must provide a token type, which prefixes the token itself (e.g. "Bearer" or "token")

func LogrusStreamServerInterceptor

func LogrusStreamServerInterceptor() grpc.StreamServerInterceptor

LogrusStreamServerInterceptor returns grpc.StreamServerInterceptor which populates request-scoped logrus logger with account_id field

func LogrusUnaryServerInterceptor

func LogrusUnaryServerInterceptor() grpc.UnaryServerInterceptor

LogrusUnaryServerInterceptor returns grpc.UnaryServerInterceptor which populates request-scoped logrus logger with account_id field

func OutgoingContext

func OutgoingContext(ctx context.Context) context.Context

OutgoingContext set to outgoing context request_id, auth_token, X-Forwarded-For, x-geo- and x-b3- headers value

func OutgoingContextWithCustomParams

func OutgoingContextWithCustomParams(ctx context.Context, keys ...string) context.Context

OutgoingContextWithCustomParams set to outgoing context specified parameters from incoming context by keys
