sockets - Dio-Flutter Image Upload返回套接字异常

Question

我尝试使用Dio插件支持的formData上传图像。

FormData formData = new FormData.from(
        {"profile_image": UploadFileInfo(image, "profile_image.jpg")});
    var response = await _dio.post(ApiConfiguration.getUploadImageUrl().toString(),data: formData);

但是它的返回错误。

DioError [DioErrorType.DEFAULT]: SocketException: OS Error: Connection reset by peer, errno = 54, address = 3.122.199.93, port = 62181

任何帮助，将不胜感激。

v3中不建议使用UploadFileInfo和FormData.from。文档需要更清晰和更新。我浪费了一天的大部分时间。

我用dio通过这种方式发布带有其他信息的文件路径:

 Dio dio = new Dio();
  FormData formData = new FormData();
  formData.add(
    "apiKey",
    "my_api_key",
  );
  formData.add(
    "file",
    "image_path",
  );
  Response response = await dio.post(
    "https://localhost",
    data: formData,
    onSendProgress: (int sent, int total) {
      // do something
    },
  ).catchError((onError) {
    throw Exception('something');
  });
