http - Dart:带有 header 的 HTTP GET

Question

我正在创建一个与 LIFX 一起使用的 Flutter 应用程序。我正在尝试按照他们的指示here ，但我在向我的 HTTP GET 请求添加 header 时遇到问题。

TestHttpGet() async {
  var httpClient = new HttpClient();
  var header = "Bearer $token"; //token hidden
  var url = 'https://api.lifx.com/v1/lights/all/state';

  String result;
  try {
    var request = await httpClient.getUrl(Uri.parse(url));
    request.headers.set("Authorization", header);
    var response = await request.close();
    if (response.statusCode == HttpStatus.OK) {
          var json = await response.transform(UTF8.decoder).join();
          print(json);
          var data = JSON.decode(json);
          result = data['brightness'].toString();
        } else {
          result =
              'Error getting response:\nHttp status ${response.statusCode}';
        }
      } catch (exception) {
        result = 'Failed parsing response';
      }

返回 Error getting response: Http status 404。我已经尝试了 request.headers .set .add [HttpHeaders.Authorization] = "header" 的各种方法，都返回 404。任何建议都将不胜感激。

您可以通过 Map<String, String>到http.get调用headers参数如下:

await httpClient.get(url, headers: {
  'Authorization': 'Bearer $token',
});
