Naos.FluentUri

A fluent grammar on top of the .NET Uri object for building up the Uri of a RESTful service and calling it with the appropriate information.

Use - Referencing in your code

The entire implemenation is in a single file so it can be included without taking a dependency on the NuGet package if necessary preferred.

• Reference the NuGet package: http://www.nuget.org/packages/Naos.FluentUri.
  OR
• Include the single file in your project: https://raw.githubusercontent.com/NaosFramework/Naos.FluentUri/master/Naos.FluentUri/Naos.FluentUri.cs.

Use - Building up the Uri

• Adding segments to the URL

• To get http://baseUrlOfService/subPath use new Uri("http://baseUrlOfService").AppendPathSegment("subPath");
• Trailing slashes are handled... http://baseUrlOfService/subPath can also be done using new Uri("http://baseUrlOfService/").AppendPathSegment("subPath");

• Adding query string parameters

• To get http://url?myParam=aValue use new Uri(http://url).AppendQueryStringParam("myParam", "aValue");
• Can also be done in batches by using .AppendQueryStringParams(/* IDictionary<string, string> */); or .AppendQueryStringParams(/* ICollection<KeyValuePair<string, string>> */);
• Will work correctly out of order too... http://url/path?q=hello can be done using new Uri("http://url").AppendQueryStringParam("q", "hello").AppendPathSegment("path"); although this is not really recommended as it doesn't read great...

Use - Calling the Uri

• Void Return vs. Typed Return

• Void Return Usage:
  • new Uri("http://api/Objects/42/Setting").Put();
• Typed Return Usage:
  • MyObject returnedData = net Uri("http://api/Objects/42").Get<MyObject>();

• The four main verbs are currently supported as first class methods as well as a method to pass any verb as a string.

• GET - new Uri("http://api/Objects/42").Get();
• POST - new Uri("http://api/Objects/").Post();
• PUT - new Uri("http://api/Objects/42/Setting").Put();
• DELETE - new Uri("http://api/Objects/42").Delete();
• "Custom Verb" - new Uri("http://api/Objects/42").CallWithVerb("Custom Verb");

• There are additional decorators for the call for standard operations.

• Add a body to the request:
  • new Uri("http://api/Objects/").WithBody(new MyObject()).Post();
• Add a cookie to the request:
  • // Cookie can also be of type HttpCookie...
  • var cookie = new Cookie(".ASPXAUTH", "[AuthCookieValue]") { Expires = DateTime.Now.AddDays(30) };
  • var obj = new Uri("http://api/Objects/42").WithCookie(cookie).Get<MyObject>();
• Add headers to the request:
  • // Headers can also be of type WebHeaderCollection or NameValueCollection..
  • var headers = new[] { new KeyValuePair<string, string>("Auth-Token", "[AuthTokenValue]") };
  • var obj = new Uri("http://api/Objects/42").WithHeaders(headers).Get<MyObject>();
• Update the timeout of the request:
  • var obj = new Uri("http://api/Objects/42").WithTimeout(TimeSpan.FromHours(1)).Get<MyObject>();
• Save response headers using a lambda:
  • KeyValuePair<string, string>[] responseHeadersFromCall;
  • new Uri("http://api/Auth/Login").WithResponseHeaderSaveAction(responseHeaders => responseHeadersFromCall = responseHeaders).Post();

Combined Examples

• Example of a request that might authenticate against a system.

var loginResponse = new Uri("http://auth.services.com") .AppendPathSegment("login") .WithBody(loginRequest) .Post();

* Example of a request that might update a user's zip code in the system.
 - ```
new Uri("http://user.services.com")
            .AppendPathSegment("user")
            .AppendPathSegment(user.Id)
            .AppendPathSegment("zipCode")
            .AppendPathSegment(user.ZipCode)
            .WithCookie(authCookieToAllowThis)
            .Put();
