对于基本身份验证,我已经实现了一个HttpMessageHandler基于Darin Dimitrov在这里回答的示例的自定义:https://stackoverflow.com/a/11536349/270591

代码创建具有用户名和角色principal的类型实例,GenericPrincipal然后将此主体设置为线程的当前主体:

Thread.CurrentPrincipal = principal;

稍后在ApiController方法中,可以通过访问controllers User属性来读取主体:

public class ValuesController : ApiController
{
    public void Post(TestModel model)
    {
        var user = User; // this should be the principal set in the handler
        //...
    }
}

这似乎工作正常,直到我最近添加了一个MediaTypeFormatter使用该Task库的自定义,如下所示:

public override Task<object> ReadFromStreamAsync(Type type, Stream readStream,
    HttpContent content, IFormatterLogger formatterLogger)
{
    var task = Task.Factory.StartNew(() =>
    {
        // some formatting happens and finally a TestModel is …

我能够在global.asax.cs中为Web API路由ala成功注册一个自定义路由处理程序(从IRouteHandler派生):

        routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "{client}/api/1.0/{controller}/{action}/{id}",
            defaults: new{id = UrlParameter.Optional}
        ).RouteHandler = new SingleActionAPIRouteHandler();

但是,当我尝试为集成测试设置内存主机时,我似乎无法找到一种方法,当我调用HttpConfiguration.Routes.MapRoute时,我无法在返回的IHttpRoute上设置处理程序.

我应该采用不同的方式(例如使用自定义的HttpControllerSelector)吗？在两种情况下,我显然都喜欢这样做.

谢谢,马特

所以我最终做的基本上是遵循下面的建议,但只是重写HttpControllerDispatcher类,如下所示:

public class CustomHttpControllerDispatcher : HttpControllerDispatcher
{
    public CustomHttpControllerDispatcher(HttpConfiguration configuration) : base(configuration)
    {
    }
    protected override Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
    {
        // My stuff here

        return base.SendAsync(request, cancellationToken);
    }
}
