Flurl

Flurl is a modern, fluent, asynchronous, testable, portable, buzzword-laden URL builder and HTTP client library.

var result = await "https://api.mysite.com" .AppendPathSegment("person") .SetQueryParams(new { api_key = "xyz" }) .WithOAuthBearerToken("my_oauth_token") .PostJsonAsync(new { first_name = firstName, last_name = lastName }) .ReceiveJson<T>(); [Test] public void Can_Create_Person() { // fake & record all http calls in the test subject using var httpTest = new HttpTest(); // arrange httpTest.RespondWith("OK", 200); // act await sut.CreatePersonAsync("Frank", "Reynolds"); // assert httpTest.ShouldHaveCalled("http://api.mysite.com/*") .WithVerb(HttpMethod.Post) .WithContentType("application/json"); }

Get it on NuGet:

PM> Install-Package Flurl.Http

Or get just the stand-alone URL builder without the HTTP features:

PM> Install-Package Flurl
