type EncodedJwt ¶

type EncodedJwt string

func EncodeJwt(secret Secret, claims *jwt.StandardClaims) (EncodedJwt, error)

func GenJwt(secret Secret, fileId string) EncodedJwt

func GetJwt(r *http.Request) EncodedJwt

type Guard ¶

type Guard struct {
	SecretKey Secret
	// contains filtered or unexported fields
}

Guard is to ensure data access security. There are 2 ways to check access:

1. white list. It's checking request ip address.
2. JSON Web Token(JWT) generated from secretKey. The jwt can come from:
1. url parameter jwt=...
2. request header "Authorization"
3. cookie with the name "jwt"

The white list is checked first because it is easy. Then the JWT is checked.

The Guard will also check these claims if provided: 1. "exp" Expiration Time 2. "nbf" Not Before

Generating JWT:

1. use HS256 to sign
2. optionally set "exp", "nbf" fields, in Unix time, the number of seconds elapsed since January 1, 1970 UTC.
