当我尝试进行json解码时,出现了错误:期望一个类型为'List'的值,但实际却得到了'_JsonMap'类型的值。
我的代码:
我的代码:
static Future<Response<Localizacao>> getLocalizacao(String cep) async {
await Future.delayed(Duration(milliseconds: 200));
try {
Map<String, String> headers = {
'Authorization': 'Token token=9e034db1f315356f30'};
String protocol = 'https://cors-anywhere.herokuapp.com/';
String uri =
'https://www.cepaberto.com/api/v3/cep?cep=' + cep;
final endpoint = "&format=json";
String url = protocol + uri + endpoint;
final response = await http.get(url, headers: headers);
if (response.statusCode == 200) {
final json = response.body;
List list = (jsonDecode(json) as List<dynamic>) ;
final local = list.map<Localizacao>((map) => Localizacao.fromJson(map)).toList();
return Response(true, msg: "OK", result: local[0]);
} else {
return Response(false, msg: "Erro ao conectar no web service");
}
} catch (e) {
return Response(false, msg: "Erro ao conectar no web service");
}
}
我尝试了其他方法,比如:
List list = convert.json.decode(response.body);
List list = convert.json.decode(json);
