Function ProcessRequestFirstMatchOf

api/api.go:140–152

ProcessRequestFirstMatchOf reads a JSON blob for the request and returns the first match of a set of keywords. For example, a request might have one of the following combinations: (foo=1, bar=2), (foo=1), and (bar=2) By giving a specific ordering of those combinations, we could decide how to accept

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

// By giving a specific ordering of those combinations, we could decide how to accept
// the request.

	blob, err := readRequestBlob(r)
	if err != nil {
		return nil, nil, err
	}

	for _, set := range keywordSets {
		if matchKeywords(blob, set) {
			return blob, set, nil
		}
	}
	return nil, nil, errors.NewBadRequestString("no valid parameter sets found")
