HTTP 连接问题

Question

几天来，当我从端点 加载数据时，我一直收到此错误。发生异常。 ClientException(连接在收到完整 header 之前关闭)

import 'package:http/http.dart' show Client;

Client client = Client();

Future<Platoons> fetchMeatifyById(String id) async {
    final response = await client.get('$_baseApi/platoons/$id');

    if (response.statusCode == 200 || response.statusCode == 201) {
      return Platoons(json.decode(response.body));
    } else {
      throw Exception('Failed to load platoon');
    }
  }

Answer 1

为 Dart 使用另一个 Http 客户端解决了上述问题 Dio ，简单但功能强大，能够控制应用程序。

简单的 HTTP 请求

class CartApiProvider {
  Dio _dio;

  CartApiProvider(){
    _dio = new Dio();
    _dio.interceptors.add(MeatityHttpInterceptor());      
  }  

 Future<OrderDetailResponse> fetchOrderInfo(String orderNo) async {
    try{
      Response response = await _dio.get('/orders/$orderNo');
      return OrderDetailResponse.fromJson(response.data);
    }catch (error, stacktrace){
      return OrderDetailResponse.withError(HttpErrorHandler.handleError(error));
    }
  }

}
