Response Content

HttpBuildR provides a set of methods to modify the content of an HttpResponseMessage object in a fluent manner.

WithContent Method

The WithContent method modifies the response content.

Usage:

HttpResponseMessage response = new HttpResponseMessage();
response = response.WithContent(new StringContent("content"));
string result = await response.Content.ReadAsStringAsync(
    TestContext.Current.CancellationToken
);
Assert.Equal("content", result);
Assert.Equal(
    "text/plain; charset=utf-8",
    response.Content.Headers.ContentType!.ToString()
);

WithJsonContent Method

The WithJsonContent method modifies the response content with JSON content.

Usage:

HttpResponseMessage response = new HttpResponseMessage();
response = response.WithJsonContent(new { Name = "Ben", Age = "Unknown" });
string result = await response.Content.ReadAsStringAsync(
    TestContext.Current.CancellationToken
);
Assert.Equal("{\"Name\":\"Ben\",\"Age\":\"Unknown\"}", result);
Assert.Equal(
    "application/json; charset=utf-8",
    response.Content.Headers.ContentType!.ToString()
);

WithXmlContent Method

The WithXmlContent method modifies the response content with XML content.

Usage:

[XmlRoot("Widget")]
public class Widget
{
    public string? Name { get; set; }
    public int PartNumber { get; set; }
}

[Fact]
public async Task TestWithXmlContentMethod()
{
    HttpResponseMessage response = new HttpResponseMessage();
    response = response.WithXmlContent(new Widget { Name = "Doohickey", PartNumber = 10 });
    string result = await response.Content.ReadAsStringAsync(
        TestContext.Current.CancellationToken
    );
    Assert.Equal(
        "<?xml version=\"1.0\" encoding=\"utf-8\"?>"
            + "<Widget xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\">"
            + "<Name>Doohickey</Name>"
            + "<PartNumber>10</PartNumber>"
            + "</Widget>",
        result
    );
    Assert.Equal(
        "text/xml; charset=utf-8",
        response.Content.Headers.ContentType!.ToString()
    );
}

WithTextContent Method

The WithTextContent method modifies the response content with text content.

Usage:

HttpResponseMessage response = new HttpResponseMessage();
response = response.WithTextContent("content");
string result = await response.Content.ReadAsStringAsync(
    TestContext.Current.CancellationToken
);
Assert.Equal("content", result);
Assert.Equal(
    "text/plain; charset=utf-8",
    response.Content.Headers.ContentType!.ToString()
);

WithFormUrlContent Method

The WithFormUrlContent method modifies the response content with FormUrlEncodedContent.

Usage:

HttpResponseMessage response = new HttpResponseMessage();
response = response.WithFormUrlContent(
    new KeyValuePair<string, string>("key", "value")
);
string result = await response.Content.ReadAsStringAsync(
    TestContext.Current.CancellationToken
);
Assert.Equal("key=value", result);
Assert.Equal(
    "application/x-www-form-urlencoded",
    response.Content.Headers.ContentType!.ToString()
);
