Some examples in C#

[cGiesen]

Dear Nikki,
I just start to use your API.
I'm a really newby in NextCloud! Thats why I run in lot of errors.
Are thre some examples for C# and FW472 for testing an looking?

In the momentI allways run in this error:
"the requested address is not valid in its context" in line 670 api.cs and I didn't know, is that a error from my NextCloud server or an error of my coding.

Regards Carsten

First thing is to get the unit tests supplied with the project working.Run a test (it will probably fail) - this will create a settings file in your personal app settings folder (see readme for where that is). Edit it to put in your Nextcloud server url, your login name and password, etc. Make sure login tests are set to run (in the settings file). Then run the tests again, starting with login. Regards Nikki On 24 Dec 2019 8:27 am, Carsten Giesen <[email protected]> wrote:Dear Nikki, I just start to use your API.

Thats the problem. I see the folder, but no setting.json or TestSettings.json

for that, save must be called, but isn't

I change the code, if no JSON file, create one.

But I get the error by this row: "listener.Bind(localEndPoint);"

The requested address is not valid in its context

Perhaps wrong settings in JSON, but I didn't have any idea, whats the correct on.

Why not put in a call to save?Regards Nikki On 24 Dec 2019 11:55, Carsten Giesen <[email protected]> wrote:Thats the problem.

a Demo for the TestSettings.json would be Nice....
The folder is generated, but not the json.

Yes, that would be nice! Even a bit more descriptions of how to.

Hi, news about this issue? we have a demo of this file?

Hi,

I just managed to create a TestSettings.json file in the C:\Users\<USERNAME>\AppData\Local\NextcloudApi folder on a windows machine.

{
  "ModifyTests": true,
  "DestructiveTests": false,
  "TestUser": null,
  "TestGroup": null,
  "ServerUri": "https://<nextcloud-url>", <-- SET
  "ApplicationName": "<ServiceName>", <-- SET
  "RedirectUri": "https://<nextcloud-url>", <-- SET
  "RedirectAfterLogin": null,
  "PageToSendAfterLogin": null,
  "LoginExpiryTime": 108000,
  "ClientId": null,
  "ClientSecret": null,
  "AccessToken": null,
  "CsrfToken": null,
  "RefreshToken": null,
  "TokenExpires": "0001-01-01T00:00:00",
  "User": null,
  "Username": "<username>", <-- SET
  "Password": "<password>", <-- SET
  "RefreshTokenIfDueToExpireBefore": "1.00:00:00",
  "LogRequest": 0,
  "LogResult": 0
}

I did set all the fields marked with <-- SET and was able to run the ShowList test.

[TestClass]
public class NextCloudDeploymentServiceTest : TestBase
{

    [TestMethod]
    public void ShowList()
    {
        ShowList(CloudFolder.List(Api, Settings.Username));
    }
}

I think it would be nice to include this settings file in the repo too.

Can anyone test and confirm this?

This is great stuff! Here is a short C# console app written in VS 2022 (.Net Framework 4.8) that illustrates one function:

using System;
using System.Collections.Generic;
using System.IO;
using System.Threading.Tasks;
using NextcloudApi;

namespace NextcloudHelper
{
internal class Program
{
public static Settings _settings;
public static Api _api;

static void Main(string[] args)
{
  Task<List<CloudInfo>> cloudInfo = CloudFolder.List(Api, Settings.Username);
  List<CloudInfo> result = RunTask(cloudInfo);

  foreach (CloudInfo o in result)
  {
    Console.WriteLine(o);
  }
  Console.ReadKey();
}

public static T RunTask<T>(Task<T> task)
{
  T t = task.Result;
  Console.WriteLine(t);
  return t;
}


public static Api Api
{
  get
  {
    if (_api == null)
    {
      _api = new Api(Settings);
    }
    return _api;
  }
}

public static Settings Settings
{
  get
  {
    if (_settings == null)
    {
      string dataPath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData), "NextcloudApi");
      Directory.CreateDirectory(dataPath);
      string filename = Path.Combine(dataPath, "TestSettings.json"); // C:\Users\Administrator\AppData\Local\NextCloudAPI
      _settings = new Settings();
      _settings.Load(filename);
      List<string> errors = _settings.Validate();
      if (errors.Count > 0)
        throw new ApplicationException(string.Join("\r\n", errors));
    }
    return _settings;
  }
}

}
}

You will need to reference Newtonsoft.Json 12.0.2 and MimeMapping 1.0.1.12 from Nuget.

What I would like to know is how do you form the link to a file that I can provide to an eligible user for them to access/download the file from Nextcloud? You can copy the internal link to the clipboard in Nextcloud, which looks something like:
http://localhost:8080/f/320
When you put this URL in the browser, it shows as:
http://localhost:8080/apps/files/?dir=/&fileid=6
It then displays the contents of the referenced file.

How can I derive this internal link programmatically?

Answer to my question (pretty simple) - Insert these lines:

  CloudInfo props = RunTask(CloudInfo.GetProperties(Api, Settings.Username + "/ChangeLog.txt", CloudInfo.Properties.FileId));
  Console.WriteLine("FileId for ChangeLog.txt is " + props.FileId.ToString() + ", Id is " + (props.Id == null ? "(null)" : props.Id.ToString()) + ".");
