Question

我正在使用val formData = MultipartFormData( dataParts = Map("" -> Seq("dummydata")), files = Seq(file), badParts = Seq())发出Dio请求

HTTP

我正在回复的答复

  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);
    }

但是{ "x_id": "home" }抛出了异常。

json.decode(response.data)

奇怪的是，当我将type '_InternalLinkedHashMap<String, dynamic>' is not a subtype of type 'String'替换为Dio时，http.get(url)的工作原理与相同的解决方案完全相同

Answer 1

您的响应数据已经是一个地图，因此您可以轻松地做到这一点：

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);

Answer 2

遵循此方法 将响应作为字符串。现在您可以对其进行解码...
