ReqHub 1.1.3

ReqHubNuGet

ReqHub middleware for C# projects. Distribute your API using the ReqHub platform in just a few lines! For more information, visit https://reqhub.io.

Distributing an API

To distribute an API for clients to consume with API keys, add these two lines to your Startup.cs:

/// Startup.cs

public class Startup
{
    public void ConfigureServices(IServiceCollection services)
    {
        // Visit https://reqhub.io to get your API keys
        services.AddReqHub("yourPublicKey", "yourPrivateKey");
    }

    public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {
        // ...
        // app.UseRouting();
        
        // Put this after app.UseRouting() and before app.UseEndpoints().
        // It verifies requests against the platform and either
        // continues execution or returns a 403 forbidden response
        // if the request is invalid (bad API key, contents tampered with, etc.)
        app.UseReqHub();
        
        // app.UseEndpoints(...);
        // ...
    }
}

That's it! 🎉

Identity

You may want to be able to uniquely identify a client. Inside your controller methods you can access the clientId with:

this.User.GetClientId();

How it works

Clients consuming your API create a request hash using their own API keys, which the middleware forwards to the platform along with your request hash. If everything matches up on the platform, the request is allowed to continue.

Consuming an API

To consume an API, configure a client and inject it into your controllers/services.

/// Startup.cs

public class Startup
{
    // ...
    
    public void ConfigureServices(IServiceCollection services)
    {
        // Visit https://reqhub.io to get your API keys
        services.AddApiClient("https://api-base-address/", "yourPublicKey", "yourPrivateKey", "serviceName");
        
        // Add as many as you like!
        services.AddApiClient("https://api2-base-address/", "anotherPublicKey", "anotherPrivateKey", "serviceName2");
    }
}

(it looks like a lot of code, but we promise it isn't 👌):

/// ExampleController.cs

public class ExampleController : ControllerBase
{
    private readonly IApiClient exampleApiClient;

    // Resolve the API client using dependency injection
    public ExampleController(ApiClientResolver apiClientResolver)
    {
        this.exampleApiClient = apiClientResolver("serviceName");
    }

    [HttpGet]
    public async Task<IEnumerable<Example>> Get()
    {
        return await this.exampleApiClient.GetAsync<IEnumerable<Example>>("example/endpoint");
    }
}
