使用 WebDav 在 NextCloud 中创建“File-Drop (Upload Only)”共享

Question

使用 NextCloud，我想知道是否可以使用 WebDav 创建“FileDrop（仅上传）”共享。我在 NextClouds 网站和 WebDav RFC 规范中都找不到有关此的任何文档。这是 Nextcloud 网络界面上的一项功能。

我正在使用 .NET 和 WebDav 客户端库

Answer 1

我找到了自己的答案。把它贴在这里以防有人偶然发现它。

要使用 API 在 Nextcloud 上共享文件夹，您需要使用 OCS Share API 而不是 WebDav OCS Sharing API

需要创建权限设置为“Create == 4, shareType == 3”的共享

编辑： 我写这段代码已经有一段时间了，但我希望它仍然有效。没有测试它，因为最后我没有在我的项目中使用代码。

 public class NextCloud
{
    private INextCloudConfig _config;
    private HttpClient _client;
    public NextCloud(INextCloudConfig config, string userName, string password)
    {
        _config = config;
        var credentials = Encoding.ASCII.GetBytes(userName + ":" + password);
        _client = new HttpClient();
        _client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Basic", Convert.ToBase64String(credentials));

    }

    public async Task<HttpResponseMessage> CreateFolderAsync(string path)
    {
        HttpRequestMessage request = new HttpRequestMessage(new HttpMethod("MKCOL"), _config.WebDavAddress + "/" + path);
        HttpResponseMessage response = await _client.SendAsync(request);
        return response;
    }

    public async Task<HttpResponseMessage> CreateShareAsync(string path, ShareType shareType, Permissions permissions)
    {
        HttpRequestMessage request = new HttpRequestMessage(new HttpMethod("POST"), new Uri(_config.OCSAddress + "/shares?format=json"));
        request.Headers.Add("OCS-APIRequest", "true");

        var parameters = new List<KeyValuePair<string, string>>();
        parameters.Add(new KeyValuePair<string, string>("shareType", ((int)shareType).ToString()));
        parameters.Add(new KeyValuePair<string, string>("shareWith", null));
        parameters.Add(new KeyValuePair<string, string>("path", path));
        parameters.Add(new KeyValuePair<string, string>("permissions", ((int)permissions).ToString()));
        //parameters.Add(new KeyValuePair<string, string>("publicUpload", "true"));
        
        request.Content = new FormUrlEncodedContent(parameters);
        HttpResponseMessage response = await _client.SendAsync(request);

        var responseContent = response.Content.ReadAsStringAsync().Result;
        var json = JsonDocument.Parse(responseContent);

        return response;
    }
}

public interface INextCloudConfig
{
    string WebDavAddress { get; }
    string OCSAddress { get; }
}

public class NextCloudConfig : INextCloudConfig
{
    private const string DEFAULTWEBDAVSUFFIX = "remote.php/webdav/";
    private const string DEFAULTOCSSUFFIX = "ocs/v2.php/apps/files_sharing/api/v1/";

    private static string _baseAddress = "";
    private static string _webdavSuffix = "";
    private static string _ocsSuffix = "";

    public string WebDavAddress
    {
        get => _baseAddress + "/" + _webdavSuffix;
    }

    public string OCSAddress
    {
        get => _baseAddress + "/" + _ocsSuffix;
    }

    public NextCloudConfig(string baseAddress) : this(baseAddress, DEFAULTWEBDAVSUFFIX, DEFAULTOCSSUFFIX)
    {
        
    }

    public NextCloudConfig(string baseAddress, string webdavSuffix, string ocsSuffix)
    {
        _baseAddress = baseAddress.TrimEnd('/');
        _webdavSuffix = webdavSuffix.TrimEnd('/');
        _ocsSuffix = ocsSuffix.TrimEnd('/');
    }

}

public enum Permissions
{
    Read = 1,
    Update = 2,
    Create = 4, 
    Delete = 8,
    Share = 16,
    All = 31
}

public enum ShareType
{
    User = 0,
    Group = 1,
    PublicLink = 3
}

static void Main(string[] args)
{
    Run().Wait();
}

public static async Task Run()
{
    NextCloudConfig config = new NextCloudConfig("https://url.to.nexcloudinstance");
    NextCloud nc = new NextCloud(config, "john.doe@gmail.com", "passw0rd");
    await nc.CreateFolderAsync(path);
    await nc.CreateShareAsync(path, ShareType.PublicLink, Permissions.Create);

    Console.ReadLine();
 
}

这是我的测试项目中的代码。这是一个简单的命令提示符应用程序。我希望这对你有帮助。我发布的链接仍然有效，并提供了有关不同枚举的更多信息。
