android - DIO 响应解码问题

Question

我正在使用 Dio 来发出 HTTP 请求

  var dio = Dio();
    var response =
        await dio.get(URL);
    final responseBody = json.decode(response.data);

    final statusCode = response.statusCode;

    if (statusCode != 200 || responseBody == null) {
      print("status code:$statusCode");
      throw new ServerExceptionHandler(
          "An error ocurred : [Status Code : $statusCode]", statusCode);
    }

A response I am paring

{
"x_id": "home"
}

但是 json.decode(response.data) 抛出异常。

type '_InternalLinkedHashMap<String, dynamic>' is not a subtype of type 'String'

奇怪的是，当我将 Dio 替换为 http.get(url) 时，json.decode(response.body) 完美运行同样的 react

您的响应数据已经是一个 map ，因此您可以简单地这样做:

var response = await dio.get(_url);
var responseBody = response.data;
print(responseBody);

这是显式类型:

Response<Map> response = await dio.get(_url);
Map responseBody = response.data;
print(responseBody);
