getParamsPath method

(String, Map<String, Object?>) getParamsPath(String clientPath, String serverPath)

Extracts parameters from the client path and server path.

The clientPath parameter is the path from the client's request. The serverPath parameter is the path defined in the route.

Returns a tuple where:

• The first element is the processed server path.
• The second element is a map of URL parameters extracted from the client path.

Implementation

(String, Map<String, Object?>) getParamsPath(
  String clientPath,
  String serverPath,
) {
  String resultKey = serverPath;
  Map<String, Object?> resultParams = {};

  var serverUri = Uri(path: serverPath);
  var clientUri = Uri(path: clientPath);

  if (serverUri.pathSegments.length != clientUri.pathSegments.length) {
    return (resultKey, resultParams);
  }

  for (int i = 0; i < clientUri.pathSegments.length; i++) {
    var key = Uri.decodeFull(serverUri.pathSegments[i]);
    if (!key.startsWith("{") || !key.endsWith("}")) {
      continue;
    } else {
      key = key.replaceAll("{", "").replaceAll("}", "");
      resultKey = resultKey.replaceFirst("{$key}", clientUri.pathSegments[i]);
      resultParams[key] = clientUri.pathSegments[i];
    }
  }

  return (resultKey, resultParams);
