IntelligentPlant.IndustrialAppStore.DependencyInjection 3.1.0

IntelligentPlant.IndustrialAppStore.DependencyInjection

This package defines types and extension methods to assist with registering Industrial App Store services with Microsoft.Extensions.DependencyInjection.

Please consider using one of the following packages instead of using this package directly:

The packages can also be used to write on-premises apps that interface with a local Data Core API instance.

Getting Started

To register a scoped IndustrialAppStoreHttpClient service with an IServiceCollection, call the AddIndustrialAppStoreApiServices extension method:

var builder = services.AddIndustrialAppStoreApiServices();

This returns an IIndustrialAppStoreBuilder object that can be used to customise the registered services via additional extension method calls. For example, to customise the HttpClient used by the IndustrialAppStoreHttpClient service:

var builder = services.AddIndustrialAppStoreApiServices(configureHttpBuilder: http => http.ConfigurePrimaryHttpMessageHandler(() => new SocketsHttpHandler() {
    EnableMultipleHttp2Connections = true
}));

Once you have built your container, you can inject the IndustrialAppStoreHttpClient service into your application components as required.

Remember that IndustrialAppStoreHttpClient is registered as a scoped service.

Authentication

By default, the scoped AccessTokenProvider service is used to provide the Industrial App Store access token for the IndustrialAppStoreHttpClient service.

The default AccessTokenProvider service registration does not return an access token, meaning that calls to Industrial App Store APIs will fail. To configure an AccessTokenProvider service that returns an access token, you can do one of the following:

Replacing the default AccessTokenProvider registration

You can replace the default AccessTokenProvider registration with a custom implementation that returns an access token. For example:

var builder = services
    .AddIndustrialAppStoreApiServices()
    .AddAccessTokenProvider((IServiceProvider provider) => {
        var accessTokenService = provider.GetRequiredService<MyTokenService>();
        return (CancellationToken ct) => accessTokenService.GetAccessTokenAsync(ct);
    });

Manually setting the access token factory

After creating a new IServiceScope, you can retrieve the AccessTokenProvider service from the service provider and set the AccessTokenProvider.Factory property to a factory method that returns an access token. For example:

using var scope = serviceProvider.CreateScope();

var accessTokenProvider = scope.ServiceProvider.GetRequiredService<AccessTokenProvider>();
accessTokenProvider.Factory = (CancellationToken ct) => new ValueTask<string?>("my-access-token");

var client = scope.ServiceProvider.GetRequiredService<IndustrialAppStoreHttpClient>();
var dataSources = await client.DataSources.GetDataSourcesAsync();
