Function ParseFromRequest

request/request.go:15–40

ParseFromRequest extracts and parses a JWT token from an HTTP request. This behaves the same as Parse, but accepts a request and an extractor instead of a token string. The Extractor interface allows you to define the logic for extracting a token. Several useful implementations are provided. You

(req *http.Request, extractor Extractor, keyFunc jwt.Keyfunc, options ...ParseFromRequestOption)

//
// You can provide options to modify parsing behavior
func ParseFromRequest(req *http.Request, extractor Extractor, keyFunc jwt.Keyfunc, options ...ParseFromRequestOption) (token *jwt.Token, err error) {
	// Create basic parser struct
	p := &fromRequestParser{req, extractor, nil, nil}

	// Handle options
	for _, option := range options {
		option(p)
	}

	// Set defaults
	if p.claims == nil {
		p.claims = jwt.MapClaims{}
	}
	if p.parser == nil {
		p.parser = &jwt.Parser{}
	}

	// perform extract
	tokenString, err := p.extractor.ExtractToken(req)
	if err != nil {
		return nil, err
	}

	// perform parse
	return p.parser.ParseWithClaims(tokenString, p.claims, keyFunc)
}

// ParseFromRequestWithClaims is an alias for ParseFromRequest but with custom Claims type.
