CanonicalQueryString

func CanonicalRequest

func CanonicalRequest(r *http.Request, signedHeaders []string) (string, error)

Build a CanonicalRequest from a regular request string

CanonicalRequest =

HTTPRequestMethod + '\n' +
CanonicalURI + '\n' +
CanonicalQueryString + '\n' +
CanonicalHeaders + '\n' +
SignedHeaders + '\n' +
HexEncode(Hash(RequestPayload))

func CanonicalURI

func CanonicalURI(r *http.Request) string

CanonicalURI returns request uri

func HexEncodeSHA256Hash

func HexEncodeSHA256Hash(body []byte) (string, error)
