C#/.NET SDK

Add Speedle.Sdk 0.1.0 with dotnet add package, then call IsAllowedAsync and CheckAsync against a local Speedle or Speedle Cloud.

The .NET SDK targets .NET 8 or later and has no dependencies. Package: Speedle.Sdk 0.1.0 on NuGet, namespace Speedle.Sdk. Reference: speedle-sdk/dotnet.

The examples check the policy described in SDKs.

Add the dependency

In a new console project:

dotnet new console -o SpeedleExample
cd SpeedleExample
dotnet add package Speedle.Sdk --version 0.1.0

Call a local Speedle

Start Speedle and create the example policy as described in SDKs. Replace Program.cs with:

using Speedle.Sdk;

try
{
    await using var speedle = new SpeedleClient(new SpeedleClientOptions
    {
        Backend = Backend.SpeedlePlus,
        Endpoint = new Uri("http://localhost:6734"),
        Auth = Auth.None(),
        ServiceName = "docs",
    });

    bool allowed = await speedle.IsAllowedAsync("alice", "get", "/docs/public");
    Console.WriteLine($"alice get /docs/public: allowed={allowed}");

    Decision d = await speedle.CheckAsync("alice", "delete", "/docs/public");
    Console.WriteLine($"alice delete /docs/public: allowed={d.Allowed} reason={d.Reason}");
}
catch (SpeedleException e)
{
    Console.Error.WriteLine($"Speedle error: {e.Message}");
    return 1;
}
return 0;

Run it:

dotnet run

Output:

alice get /docs/public: allowed=True
alice delete /docs/public: allowed=False reason=NoApplicablePolicies

Call Speedle Cloud

Speedle Cloud is coming soon.

The program reads the service name from SPEEDLE_SERVICE and the service’s token from SPEEDLE_TOKEN. SPEEDLE_ENDPOINT overrides the default endpoint https://cloud.speedle.io. Replace Program.cs with:

using Speedle.Sdk;

try
{
    await using var speedle = new SpeedleClient(new SpeedleClientOptions
    {
        Backend = Backend.SpeedleCloud,
        Endpoint = new Uri(Environment.GetEnvironmentVariable("SPEEDLE_ENDPOINT") ?? "https://cloud.speedle.io"),
        Auth = Auth.Bearer(Environment.GetEnvironmentVariable("SPEEDLE_TOKEN") ?? ""),
        ServiceName = Environment.GetEnvironmentVariable("SPEEDLE_SERVICE") ?? "",
    });

    bool allowed = await speedle.IsAllowedAsync("alice", "get", "/docs/public");
    Console.WriteLine($"alice get /docs/public: allowed={allowed}");

    Decision d = await speedle.CheckAsync("alice", "delete", "/docs/public");
    Console.WriteLine($"alice delete /docs/public: allowed={d.Allowed} reason={d.Reason}");
}
catch (SpeedleException e)
{
    Console.Error.WriteLine($"Speedle error: {e.Message}");
    return 1;
}
return 0;

Set the environment and run it. read -rs keeps the token out of your shell history and screen:

export SPEEDLE_SERVICE=docs
read -rs SPEEDLE_TOKEN && export SPEEDLE_TOKEN
dotnet run

Output, when the service has the example policy:

alice get /docs/public: allowed=True
alice delete /docs/public: allowed=False reason=NoApplicablePolicies

The token is a server-side secret. Never ship it to browsers, mobile apps or desktop clients.
