以下是我尝试将文件上传到 OneDrive 时在日志中看到的内容。

Future<void> _connectToOneDrive(BuildContext context) async {
  final onedrive = OneDrive(
    redirectURL: "https://login.live.com/oauth20_desktop.srf",
    clientID: clientID,
  );

  final success = await onedrive.connect(context);
  if (success) {
    print("Connected to OneDrive.");
    _uploadCsvToOneDrive(onedrive);
  }
}

Future<void> _uploadCsvToOneDrive(OneDrive onedrive) async {
  final csvData = convertToCsv(rows);
  final data = Uint8List.fromList(utf8.encode(csvData));

  try {
    print('Attempting to upload CSV file to OneDrive...');
    final success = await onedrive.push(data, "data.csv");

    if (!success) {
      print('Failed to upload CSV file to OneDrive.');
    } else {
      print('CSV file uploaded successfully.');
    }
  } catch (e, stackTrace) {
    print('Error during upload: $e');
    print('Stack trace: $stackTrace');
  }
}

以下是我用来将数据上传到 One Drive 的函数。我可以按照日志所述连接到 OneDrive 帐户，但在上传时却无法连接。

我可以知道正确的方法吗？

使用的软件包是 flutter_onedrive: ^1.4.0 和 oauth_webauth: ^5.1.0。

Answer 1

推这个：

final csvData = convertToCsv(rows);
final data = Uint8List.fromList(utf8.encode(csvData));

前往隔离区。 它可能严重占用 CPU 资源。 您可以简单地通过以下方式做到这一点：

import 'dart:async';

final data = await Isolate.run(() {
  final csvData = convertToCsv(rows);
  return Uint8List.fromList(utf8.encode(csvData));
};

您已经在异步函数中，因此等待不需要编辑。
