Functions

func DecodeDecryptRequest

func DecodeDecryptRequest(_ context.Context, r *http.Request) (interface{}, error)

DecodeDecryptRequest fills struct from JSON details of request

func DecodeEncryptRequest

func DecodeEncryptRequest(_ context.Context, r *http.Request) (interface{}, error)

DecodeEncryptRequest fills struct from JSON details of request

func EncodeResponse

func EncodeResponse(_ context.Context, w http.ResponseWriter, response interface{}) error

EncodeResponse is common for both the reponses from encrypt and decrypt services

func MakeDecryptEndpoint

func MakeDecryptEndpoint(svc EncryptService) endpoint.Endpoint

MakeDecryptEndpoint forms endpoint for request/response of decrypt function

func MakeEncryptEndpoint

func MakeEncryptEndpoint(svc EncryptService) endpoint.Endpoint

MakeEncryptEndpoint forms endpoint for request/response of encrypt function

Types

type DecryptRequest

type DecryptRequest struct {
	Message string `json:"message"`
	Key     string `json:"key"`
}

DecryptRequest strctures request coming from client

type DecryptResponse

type DecryptResponse struct {
	Text string `json:"text"`
	Err  string `json:"error"`
}

DecryptResponse strctures response going to the client

type EncryptRequest

type EncryptRequest struct {
	Text string `json:"text"`
	Key  string `json:"key"`
}

EncryptRequest strctures request coming from client

type EncryptResponse

type EncryptResponse struct {
	Message string `json:"message"`
	Err     string `json:"error"`
}

EncryptResponse strctures response going to the client

type EncryptService

type EncryptService interface {
	Encrypt(context.Context, string, string) (string, error)
	Decrypt(context.Context, string, string) (string, error)
}

EncryptService is a blueprint for our service

type EncryptServiceInstance

type EncryptServiceInstance struct{}

EncryptServiceInstance is the implementation of interface for micro service

func (EncryptServiceInstance) Decrypt

func (EncryptServiceInstance) Decrypt(_ context.Context, key string, text string) (string, error)

Decrypt decrypts the encrypted string to original

func (EncryptServiceInstance) Encrypt

func (EncryptServiceInstance) Encrypt(_ context.Context, key string, text string) (string, error)

Encrypt encrypts the string with given key

type InstrumentingMiddleware

type InstrumentingMiddleware struct {
	RequestCount   metrics.Counter
	RequestLatency metrics.Histogram
	Next           EncryptService
}

InstrumentingMiddleware is a struct representing middleware

func (InstrumentingMiddleware) Decrypt

func (mw InstrumentingMiddleware) Decrypt(ctx context.Context, key string, text string) (output string, err error)

func (InstrumentingMiddleware) Encrypt

func (mw InstrumentingMiddleware) Encrypt(ctx context.Context, key string, text string) (output string, err error)

type LoggingMiddleware

type LoggingMiddleware struct {
	Logger log.Logger
	Next   EncryptService
}

LoggingMiddleware wraps the logs for incoming requests

func (LoggingMiddleware) Decrypt

func (mw LoggingMiddleware) Decrypt(ctx context.Context, key string, text string) (output string, err error)

Decrypt logs the encyption requests

func (LoggingMiddleware) Encrypt

func (mw LoggingMiddleware) Encrypt(ctx context.Context, key string, text string) (output string, err error)

Encrypt logs the encyption requests
