Function ProcessRequestOneOf

api/api.go:114–133

ProcessRequestOneOf reads a JSON blob for the request and makes sure it contains one of a set of keywords. For example, a request might have the ('foo' && 'bar') keys, OR it might have the 'baz' key. In either case, we want to accept the request; however, if none of these sets shows up, the request

(r *http.Request, keywordSets [][]string)

// none of these sets shows up, the request is a bad request, and it
// should be returned.
func ProcessRequestOneOf(r *http.Request, keywordSets [][]string) (map[string]string, []string, error) {
	blob, err := readRequestBlob(r)
	if err != nil {
		return nil, nil, err
	}

	var matched []string
	for _, set := range keywordSets {
		if matchKeywords(blob, set) {
			if matched != nil {
				return nil, nil, errors.NewBadRequestString("mismatched parameters")
			}
			matched = set
		}
	}
	if matched == nil {
		return nil, nil, errors.NewBadRequestString("no valid parameter sets found")
	}
	return blob, matched, nil
}
