我在飞镖中有以下代码

import 'dart:io';
import 'package:http/http.dart' as http;

main() async {
  final url = 'https://jsonplaceholder.typicode.com/users';
  final response = await http.get(url);

  if (response.statusCode == HttpStatus.ok) {
    print(response.body);
  }
}

它工作正常，但是当我查询网址更改为 http://loterias.caixa.gov.br/wps/portal/loterias/landing/lotofacil/!ut/p/a1/04_Sj9CPykssy0xPLMnMz0vMAfGjzOLNDH0MPAzcDbz8vTxNDRy9_Y2NQ13CDA0sTIEKIoEKnN0dPUzMfQwMDEwsjAw8XZw8XMwtfQ0MPM2I02-AAzgaENIfrh-FqsQ9wBmoxN_FydLAGAgNTKEK8DkRrACPGwpyQyMMMj0VAcySpRM!/dl5/ d5/L2dBISEvZ0FBIS9nQSEh/pw/Z7_61L0H0G0J0VSC0AC4GLFAD2003/res/id=buscaResultado/c=cacheLevelPage/=/?timestampAjax=1534624870817&concurso=1703

import 'package:http/http.dart' as http;

main() async {
  final url =
      'http://loterias.caixa.gov.br/wps/portal/loterias/landing/lotofacil/!ut/p/a1/04_Sj9CPykssy0xPLMnMz0vMAfGjzOLNDH0MPAzcDbz8vTxNDRy9_Y2NQ13CDA0sTIEKIoEKnN0dPUzMfQwMDEwsjAw8XZw8XMwtfQ0MPM2I02-AAzgaENIfrh-FqsQ9wBmoxN_FydLAGAgNTKEK8DkRrACPGwpyQyMMMj0VAcySpRM!/dl5/d5/L2dBISEvZ0FBIS9nQSEh/pw/Z7_61L0H0G0J0VSC0AC4GLFAD2003/res/id=buscaResultado/c=cacheLevelPage/=/?timestampAjax=1534624870817&concurso=1703';
  final response = await http.get(url);

  if (response.statusCode == HttpStatus.ok) {
    print(response.body);
  }
}

出现以下错误：
