考虑重定向的ASP.NET Web API服务

public class ThisController : ApiController
{
    /* more methods */

    public override HttpResponseMessage Post()
    {
        var result = new HttpResponseMessage(HttpStatusCode.MovedPermanently);
        // Post requests should be made to "ThatController" instead.
        string uri = Url.Route("That", null);
        result.Headers.Location = new Uri(uri, UriKind.Relative);
        return result;
    }
}

试图验证POST数据到"api/this"会将你重定向到"api/that",我有以下测试方法:

[TestMethod]
public void PostRedirects()
{
    using (var client = CreateHttpClient("application/json"))
    {
        var content = CreateContent(expected, "application/json");
        using (var responseMessage = client.PostAsync("api/this", content).Result)
        {
            Assert.AreEqual(HttpStatusCode.MovedPermanently, responseMessage.StatusCode);
            Assert.AreEqual(new Uri("https://api.example.com/api/that"), responseMessage.Headers.Location);
        }
    }
}

protected HttpClient …

使用WebClient类,我可以轻松地获得网站的标题:

WebClient x = new WebClient();    
string source = x.DownloadString(s);
string title = Regex.Match(source, 
    @"\<title\b[^>]*\>\s*(?<Title>[\s\S]*?)\</title\>",
    RegexOptions.IgnoreCase).Groups["Title"].Value;

我想存储URL和页面标题.但是,当遵循以下链接时:

http://tinyurl.com/dbysxp

我显然想要将我重定向到的Url.

质询

有没有办法在WebClient课堂上这样做？

我怎么用HttpResponse和HttpRequest？

使用NuGet的HttpClient.

该应用程序使用client.PostAsync()发送帖子.我希望它不要遵循302重定向.

怎么样？

我想我可以AllowAutoRedirect按照这个答案中的描述进行设置.

但是如何HttpWebRequest在PostAsync()调用中使用？
