Answer 1

尝试将token添加到api头部，如下所示：

  Map<String, String> _headers = <String, String>{
    'Content-Type': 'application/json',
    'Accept': 'application/json',
  };

makeRequest(){
_headers['access_token'] = "YOUR_ACCESS_TOKEN";
    Dio dio = new Dio();
  dio.get(url,
          options: Options(
            headers: _headers,
          )));
}

请注意，密钥可能不是"access_token“，它取决于后端
