Relativity.API.Extensions 20.0.2

Relativity.API.Extensions

This library provides extension methods for the IServicesMgr interface for connecting multi-tenant microservices. It includes the following methods:

• GetInstanceBaseURL
  • Returns the Base Url and port if specified from theRelativity.Core::RestServicesUri Instance-Setting of the tenant as a string.
• GetHttpAuthorizationHandler
  • Returns a DelegatingHandler that automatically adds Authorization headers for HTTP calls. This method takes in Relativity.API.ExecutionIdentity as an input.

Installing via the .NET SDK

dotnet add package Relativity.API.Extensions

Developer Setup

Usage

Users will need to include the Extensions assembly in their ADS applications. The GetInstanceBaseURL and GetHttpAuthorizationHandler can be called using the snippet below:

using Relativity.API.Extensions;
public class AgentBaseTest : AgentBase
{
	private IServicesMgr _servicesMgr;

	public AgentBaseTest()
	{
	}

	public override string Name => "AgentBaseTest";

	public override void Execute()
	{
		_servicesMgr = Helper.GetServicesManager();
		
		// Get the auth handler
		// See advanced usage for setting an inner handler
		
		var authHandler = _servicesMgr.GetHttpAuthorizationHandler(ExecutionIdentity.CurrentUser);
		var client = new HttpClient(authHandler);

		var requestUrl = GetRequestUrl("/api/test-endpoint");

		var request = new HttpRequestMessage(HttpMethod.Get, requestUrl);

		var response = client.SendAsync(request).Result;

	}

	private Uri GetRequestUrl(string requestEndpoint)
	{
		var baseUrl = _servicesMgr.GetInstanceBaseURL();

		if (string.IsNullOrEmpty(baseUrl))
		{
			throw new InvalidOperationException("Base URL is not set.");
		}
		var fullUri = new Uri(new Uri(baseUrl), requestEndpoint);

		return fullUri;
	}
}

Advanced Usage: Setting the InnerHandler

If you want to chain additional handlers or use a custom HttpClientHandler, set the InnerHandler property before passing the handler to HttpClient:

var authHandler = _servicesMgr.GetHttpAuthorizationHandler(ExecutionIdentity.CurrentUser);
authHandler.InnerHandler = new MyCustomHandler(); // or new HttpClientHandler()
var client = new HttpClient(authHandler);

If you do not set InnerHandler, a default HttpClientHandler will be used.
