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 …

我有以下方法返回Http status code给定的Url:

public static async void makeRequest(int row, string url)
{
    string result;
    Stopwatch sw = new Stopwatch(); sw.Start();

    try
    {
        using (HttpClient client = new HttpClient())
        {
            HttpResponseMessage response = new HttpResponseMessage();
            response = await client.GetAsync(url);

            // dump contents of header
            Console.WriteLine(response.Headers.ToString());

            if (response.IsSuccessStatusCode)
            {
                result = ((int)response.StatusCode).ToString();
            }
            else
            {
                result = ((int)response.StatusCode).ToString();
            }
        }
    }
    catch (HttpRequestException hre)
    {
        result = "Server unreachable";
    }

    sw.Stop();
    long time = sw.ElapsedTicks / (Stopwatch.Frequency / …

我有一个返回HTTP 302重定向的URL,我想获取它重定向到的URL.

问题是System.Net.WebClient似乎实际上遵循它,这很糟糕.HttpWebRequest似乎也这样做.

有没有办法制作一个简单的HTTP请求并返回目标位置而不使用WebClient？

我很想做原始套接字通信,因为HTTP很简单,但网站使用HTTPS,我不想做握手.

最后,我不关心我使用哪个类,我只是不希望它遵循HTTP 302重定向:)

我正在使用FlurlHttp，并且想对某些API调用禁用AllowAutoRedirect。我知道如何使System.Net.Http.HttpClient不遵循302重定向？

WebRequestHandler webRequestHandler = new WebRequestHandler();
webRequestHandler.AllowAutoRedirect = false;
HttpClient httpClient = new HttpClient(webRequestHandler);
// Send a request using GetAsync or PostAsync
Task<HttpResponseMessage> response = httpClient.GetAsync("http://www.google.com")

但是对于Flurl，我只找到了与C＃Flurl中所述类似的方法 -将WebRequestHandler添加到FlurlClient（我尚未编译下面的代码，因此可能会有一些错误）

public class HttpClientFactoryWithWebRequestHandler : DefaultHttpClientFactory
{
    private readonly WebRequestHandler _webRequestHandler;

    public HttpClientFactoryWithWebRequestHandler (WebRequestHandler webRequestHandler ) 
    {
        _webRequestHandler = webRequestHandler ;
    }

    public override HttpMessageHandler CreateMessageHandler()
    {
        var handler =_webRequestHandler ;
//Or    var handler = new WebRequestHandler(_webRequestHandler );
        return handler;
    }
}

然后，我可以为新的FlurlClient传递设置：

WebRequestHandler webRequestHandler = new …
