使用WCF HTTP的Web API，UriTemplateMatch始终为null [英] Using the WCF HTTP Web API, UriTemplateMatch is always null

问题描述

我设置我的服务，根据我已经找到了最新的教程，一切似乎很好地工作。

I've setup my service according to the latest tutorials I've found, and everything seems to work fine.

不过，

为了访问包含QueryParameters集合WebOperationContext.Current.IncomingRequest.UriTemplateMatch类（如姓名=汤姆和放大器;年龄= 20），我需要有配置为使用WebHttpBehavior的服务。我已经成功地得到这个工作的唯一方法是将其用WebServiceHost从控制台应用程序的自我主机。我不能让它从web.config中工作或IIS或卡西尼Global.asax中。

In order to access the WebOperationContext.Current.IncomingRequest.UriTemplateMatch class which contains the QueryParameters collection (e.g. ?name=tom&age=20), I need to have the service configured to use WebHttpBehavior. The only way I've managed to get this to work is to self host it using WebServiceHost from a console application. I can't get it to work from the web.config or global.asax from IIS or cassini.

我觉得奇怪的是如何承载的东西在IIS之前，使用有关的IoC的网络API通话教程：那不是更加有用吗？他们似乎都使用根本不使用查询字符串非常简单的服务，国际奥委会！

I find it strange that tutorials on how to use the web-api talk about IoC before hosting the thing in IIS: wouldn't that be far more useful? They all seem to use extremely simple services that don't use query strings at all, with IoC!

下面是我发现，几乎提到这个问题，但不解决它的资源：

Here are the resources I've found that almost mention the problem but don't fix it:

推荐答案

您可以做这样的事情：

[ServiceContract]
public class ContactResource {
    [WebGet(UriTemplate = "")]
    public HttpResponseMessage<Contact> Get(HttpRequestMessage request) {
        var querystring = request.RequestUri.Query;
        var parameters = HttpUtility.ParseQueryString(querystring);
        var name = parameters["Name"];
        return new HttpResponseMessage<Contact>(
            new Contact()
                {
                    Id = Guid.NewGuid(),
                    Name = name
                });
    }
}

的http：//本地主机：12741 /联系人姓名=乔治

收益率：
