Sending and Checking Xml

I wasn't sure that Xml over HTTP was all that common of a use case anymore, but the very first project we used Alba on turned out to be an Xml API, so here we are.

In all cases, Alba just uses the old, built in XmlSerializer from the .Net BCL.

Sending Xml in the Request

There's a similar helper for Xml serialization that allows you to send an object as xml to the web request:

public Task send_xml(IAlbaHost host)
{
    return host.Scenario(_ =>
    {
        // This serializes the Input object to xml,
        // writes it to the HttpRequest.Body, and sets
        // the accepts & content-type header values to
        // application/xml
        _.Post
            .Xml(new Input {Name = "Max", Age = 13})
            .ToUrl("/person");

        // OR, if url lookup is enabled, this is an equivalent:
        _.Post.Xml(new Input {Name = "Max", Age = 13});
    });
}

Reading Xml from the Response

There's a helper off of the HttpResponseBody for reading Xml from the response:

public async Task read_xml(IAlbaHost host)
{
    var result = await host.Scenario(_ =>
    {
        _.Get.Url("/output");
    });

    // This deserializes the response body to the
    // designated Output type
    var output = result.ReadAsXml<Output>();

    // do assertions against the Output model

    // OR, if you just want the XmlDocument itself:
    XmlDocument document = result.ReadAsXml();
}
