Types

type GinJWTMiddleware

type GinJWTMiddleware struct {
	// Realm name to display to the user. Required.
	Realm string

	Timeout time.Duration

	// This field allows clients to refresh their token until MaxRefresh has passed.
	// Note that clients can refresh their token in the last moment of MaxRefresh.
	// This means that the maximum validity timespan for a token is TokenTime + MaxRefresh.
	// Optional, defaults to 0 meaning not refreshable.
	MaxRefresh time.Duration

	// Callback function that should perform the authentication of the user based on login info.
	// Must return user data as user identifier, it will be stored in Claim Array. Required.
	// Check error (e) to determine the appropriate error message.
	Authenticator func(c *gin.Context) (interface{}, error)

	// only after an authentication success. Must return true on success, false on failure.
	// Optional, default to success.
	Authorizator func(data interface{}, c *gin.Context) bool

	// Callback function that will be called during login.
	// Using this function it is possible to add additional payload data to the webtoken.
	// The data is then made available during requests via c.Get("JWT_PAYLOAD").
	// Note that the payload is not encrypted.

GinJWTMiddleware provides a Json-Web-Token authentication implementation. On failure, a 401 HTTP response is returned. On success, the wrapped middleware is called, and the userID is made available as c.Get("userID").(string). Users can get a token by posting a json request to LoginHandler. The token then needs to be passed in the Authentication header. Example: Authorization:Bearer XXX_TOKEN_XXX
