[Flutter] 이미지 데이터 서버에 업로드하기

 

Future<String> uploadImage(File file) async {
    String fileName = file.path.split('/').last;
    FormData formData = FormData.fromMap({
        "file":
            await MultipartFile.fromFile(file.path, filename:fileName),
    });
    response = await dio.post("/info", data: formData);
    return response.data['id'];
}

 

contentType 옵션을 추가하는 내용 포함

Future<dynamic> patchUserProfileImage(dynamic input) async {
    print("프로필 사진을 서버에 업로드 합니다.");
    var dio = new Dio();
    try {
      dio.options.contentType = 'multipart/form-data';
      dio.options.maxRedirects.isFinite;

      dio.options.headers = {'token': token};
      var response = await dio.patch(
        baseUri + '/users/profileimage',
        data: input,
      );
      print('성공적으로 업로드했습니다');
      return response.data;
    } catch (e) {
      print(e);
    }
  }
