示例1: MemoryStream
public void SelectFormatter_WithNoMatchingAcceptHeadersAndRequestContentType_PicksFormatterBasedOnObjectType
(string acceptHeader)
{
// For no accept headers,
// can write is called twice once for the request Content-Type and once for the type match pass.
// For each additional accept header, it is called once.
// Arrange
var acceptHeaderCollection = string.IsNullOrEmpty(acceptHeader) ?
null : MediaTypeHeaderValue.ParseList(new[] { acceptHeader }).ToArray();
var stream = new MemoryStream();
var httpResponse = new Mock<HttpResponse>();
httpResponse.SetupProperty<string>(o => o.ContentType);
httpResponse.SetupGet(r => r.Body).Returns(stream);
var actionContext = CreateMockActionContext(httpResponse.Object,
requestAcceptHeader: acceptHeader,
requestContentType: "application/xml");
var input = "testInput";
var result = new ObjectResult(input);
var mockCountingFormatter = new Mock<IOutputFormatter>();
var context = new OutputFormatterContext()
{
HttpContext = actionContext.HttpContext,
Object = input,
DeclaredType = typeof(string)
};
var mockCountingSupportedContentType = MediaTypeHeaderValue.Parse("application/text");
mockCountingFormatter.Setup(o => o.CanWriteResult(context,
It.Is<MediaTypeHeaderValue>(mth => mth == null)))
.Returns(true);
mockCountingFormatter.Setup(o => o.CanWriteResult(context, mockCountingSupportedContentType))

// Set more than one formatters. The test output formatter throws on write.
result.Formatters = new List<IOutputFormatter>

// Act
var formatter = result.SelectFormatter(context, result.Formatters);
// Assert
Assert.Equal(mockCountingFormatter.Object, formatter);
mockCountingFormatter.Verify(v => v.CanWriteResult(context, null), Times.Once());
// CanWriteResult is invoked for the following cases:
// 1. For each accept header present
// 2. Request Content-Type
// 3. Type based match
var callCount = (acceptHeaderCollection == null ? 0 : acceptHeaderCollection.Count()) + 2;
mockCountingFormatter.Verify(v => v.CanWriteResult(context,
It.IsNotIn<MediaTypeHeaderValue>(mockCountingSupportedContentType)),
