Usage

First of all you should create client instance using newClient() function:

var client = webdav.newClient(
    'http://localhost:6688/',
    user: 'flyzero',
    password: '123456',
    debug: true,
  );

Common settings

    // Set the public request headers
    client.setHeaders({'accept-charset': 'utf-8'});

    // Set the connection server timeout time in milliseconds.
    client.setConnectTimeout(8000);

    // Set send data timeout time in milliseconds.
    client.setSendTimeout(8000);

    // Set transfer data time in milliseconds.
    client.setReceiveTimeout(8000);

    // Test whether the service can connect
    try {
      await client.ping();
    } catch (e) {
      print('$e');
    }

Read all files in a folder

    var list = await client.readDir('/');
    list.forEach((f) {
        print('${f.name} ${f.path}');
      });

    // can sub folder
    var list2 = await client.readDir('/sub/sub/folder');
    list2.forEach((f) {
        print('${f.name} ${f.path}');
      });
    

Create folder

    await client.mkdir('/新建文件夹');

    // Recursively create folders
    await client.mkdirAll('/new folder/new folder2');

Remove a folder or file

If you remove the folder, some webdav services require a '/' at the end of the path.

    // Delete folder
    await client.remove('/new folder/new folder2/');

    // Delete file
    await client.remove('/new folder/新建文本文档.txt');

Rename a folder or file

If you rename the folder, some webdav services require a '/' at the end of the path.

    // Rename folder
    await client.rename('/新建文件夹 /', '/新建文件夹 2/', true);

    // Rename file
    await client.rename('/新建文件夹 2/test.dart', '/新建文件夹 2/test2.dart', true);

Copy a file / folder from A to B

If copied the folder (A > B), it will copy all the contents of folder A to folder B.

Some webdav services have been tested and found to delete the original contents of the B folder!!!

    // Copy all the contents of folderA to folder B
    await client.copy('/folder/folderA/', '/folder/folderB/', true);

    // Copy file
    await client.copy('/folder/aa.png', '/folder/bb.png', true);

Download file

    // download bytes
    await client.read('/folder/folder/openvpn.exe');

    // download 2 local file
    await client.read2File(
          '/folder/vpn.exe', 'C:/Users/xxx/vpn2.exe');

Upload file

    // upload local file 2 remote file
    await client.writeFromFile(
        'C:/Users/xxx/vpn.exe', '/f/vpn2.exe');

Cancel request

    CancelToken cancel = CancelToken();

    // Supports most methods
    client.mkdir('/新建文件夹', cancel)
    .catchError((err) {
      prints(err.toString());
    });

    // in other
    cancel.cancel('reason')
