Add a Path Substitution Parameter to a REST Request

See more REST Examples

Demonstrates Rest.AddPathParam, which adds or replaces a path-substitution parameter. Before a request is sent, each occurrence of the name in the URI path is replaced with its value.

import 'package:chilkat/chilkat.dart';

void main() {
  final rest = CkRest();

  // Connect to the REST server.  The 3rd argument enables TLS (use true for HTTPS on port 443),
  // and the 4th enables automatic reconnection if the connection is dropped between requests.
  final bTls = true;
  final bAutoReconnect = true;
  try {
    rest.connect('example.com', 443, bTls, bAutoReconnect);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Add path-substitution parameters.  Before a request is sent, each occurrence of the name in the
  // URI path is replaced with the value.  This keeps the path template readable.
  rest.addPathParam('{userId}', '12345');
  rest.addPathParam('{orderId}', '98765');

  // The placeholders in the path are replaced before the request is sent.
  final String responseText;
  try {
    responseText = rest.fullRequestNoBody('GET', '/users/{userId}/orders/{orderId}');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  print(responseText);
