HTTP请求无法获得完整的数据

如何解决HTTP请求无法获得完整的数据

我上这堂课：

class Weeks {
final int index;
  final int udigree;
  final int d_id;
  final String activity_a;
  final String activity_k;
  final String title_a;
  final String title_k;
  Weeks(this.index,this.udigree,this.d_id,this.activity_a,this.activity_k,this.title_a,this.title_k);
}

我使用了将来的功能来从服务器获取数据：

import 'package:flutter/material.dart';
import 'package:jiyanUquraan/classes/weekly.dart';
import 'package:http/http.dart' as http;
import 'dart:convert';
class Weekly extends StatefulWidget {
  @override
  _WeeklyState createState() => _WeeklyState();
}
class _WeeklyState extends State<Weekly> {
  @override
  Widget build(BuildContext context) {
    var widthView = MediaQuery.of(context).size.width;
    var heightView = MediaQuery.of(context).size.height;
    List weekly = [];
    Map rData = ModalRoute.of(context).settings.arguments;
    var cm_id = rData['current_m_id'];
    var u_id = rData['u_id'];
    var d_id = rData['d_id'];
    var w_id = rData['w_id'];
    // Futher Function for Get Data
    Future<List> getWeeks() async {
      print(cm_id);
      print(u_id);
      print(w_id);
      var url =
          'http://10.0.2.2/jiyan/test/api/digrees/weekly_report.php?m_id=$cm_id&u_id=$u_id&w_id=$w_id';
      var response = await http.get(url);
      var data = jsonDecode(response.body);
      print(data);
      print(data.length);
      for (var x in data) {
        Weeks _weeklyReport = Weeks(x['index'],x['udigree'],x['activity_a'],x['activity_k'],x['title_a'],x['title_k'],x['d_id']);
        weekly.add(_weeklyReport);
      }
      return weekly;
    }
    // End of Get Data
    // Create Future Builder
    return FutureBuilder(
        future: getWeeks(),builder: (context,snapshot) {
          if (snapshot.data == null) {
            return Center(
              child: Text('Loading'),);
          } else {
            return Center(child: Text('data'));
          }
        });
    // End of Futur Builder
  }
}

在打印数据及其长度时，长度是正确的，但数据不完整，如下所示：

由于无法正确获取数据，因此snapshot.data为空，如何解决此问题？ 是否由于数据为库尔德语而发生错误？

解决方法

这个错误在课堂上。 变量d_id和udigree必须为String
