Usage

Creating a client and trying to invoke getCurrentUser method:

Basic usage

Install the NuGet package Thingsboard.Net.Flurl.

PM> Install-Package Thingsboard.NET.Flurl

Then put following code into your project

// Initial factory
var factory = new FlurlTbClientFactory
{
    Options = new ThingsboardNetFlurlOptions()
    {
        BaseUrl  = "http://localhost:8080",
        Username = "tenant@thingsboard.org",
        Password = "tenant",
    }
};

// Get the client
var authClient = factory.CreateAuthClient();
var userInfo = await authClient.GetCurrentUserAsync();
Console.WriteLine($"Hello {userInfo.Email}");

You will get the output from console:

Hello tenant@thingsboard.org

Integration to ASP.NET Core

You can use the Thingsboard.NET.Flurl library in ASP.NET Core applications. Te dependency injection mode is supported.

First, add the Thingsboard.NET.Flurl.DependencyInjection library to your project:

PM> Install-Package Thingsboard.NET.Flurl.DependencyInjection

Then, register the Thingsboard.NET.Flurl services in the ConfigureServices method of Startup.cs:

// add package "Thingsboard.Net.Flurl.DependencyInjection" Version="3.4.1.1"
serviceBuilder.AddThingsboardNet(options =>
{
    options.Username = "tenant@thingsboard.org";
    options.Password = "tenant";
    options.BaseUrl  = "http://localhost:8080";
});

Then you can inject the client factory in your controllers:

public class HomeController : Controller
{
    private readonly ITbAuthClient _authClient;

    public HomeController(ITbAuthClient authClient)
    {
        _authClient = authClient;
    }

    public async Task<IActionResult> Index()
    {
        var userInfo = await _authClient.GetCurrentUserAsync();
        return View(userInfo);
    }
}

Customization options

You can customize the client options before invoke RPC methods:

public class HomeController : Controller
{
    private readonly ITbAuthClient _authClient;

    public HomeController(ITbAuthClient authClient)
    {
        _authClient = authClient;
    }

    public async Task<IActionResult> Index()
    {
        var userInfo = await auth
            .WithCredentials("newuser@thingsboard.com", "your-password")
            .WithBaseUrl("https://tb-server")
            .GetCurrentUserAsync();
        return View(userInfo);
    }
}
