C# 具有基本身份验证的WCF（远程服务器返回错误：404未找到）

在使用基本身份验证模块设置wcf（使用端口26880的http协议）服务后，我尝试从外部（部署在IIS上）访问该服务，但它会引发以下错误：

远程服务器返回错误：（404）未找到

到目前为止，我所尝试的：

删除了基本身份验证，并检查该服务是否可以在内部和外部访问，以及是否正常工作

检查服务是否实际收到了标头授权，并且用户已登录。（此操作有效）

在我的web.config文件中添加了以下行：

在添加我的基本身份验证模块后，仍然没有运气

进入IIS并确保基本身份验证已启用

启用了跟踪日志记录，显然除了查看此地址之外，我看不到任何错误：

http://localhost/ResponseService

实际上它应该是

http://localhost:26880/ResponseService

我在谷歌上搜索并尝试了与我的错误相关的所有可能的解决方案，到目前为止没有结果

这是我的客户：

    HttpWebResponse resp = null;
    string SampleXml = string.Empty;

    string baseAddress = "http://'external ip':26880/DcsResponse/XMLGate/inbound?System=84771500";
    try
    {
        string strResult = string.Empty;

        using (StreamReader readFile = new StreamReader(@"C:\Users\Alin\Desktop\testingXml.xml"))
        {
            SampleXml = readFile.ReadToEnd();
        }

        string postData = SampleXml.ToString();
        byte[] data = Encoding.UTF8.GetBytes(postData);

        string svcCredentials = Convert.ToBase64String(ASCIIEncoding.ASCII.GetBytes("alin" + ":" + "Dcs1234"));


        HttpWebRequest webrequest = (HttpWebRequest)WebRequest.Create(baseAddress);
        webrequest.Headers.Add("Authorization", "Basic " + svcCredentials);

        webrequest.Method = "POST";

        webrequest.ContentType = "text/xml"; 
        webrequest.ContentLength = data.Length;

        Stream newStream = webrequest.GetRequestStream();   
        newStream.Write(data, 0, data.Length);
        newStream.Close();

        HttpWebResponse webresponse = (HttpWebResponse)webrequest.GetResponse();

        if (webresponse.StatusCode == HttpStatusCode.OK)
        {
            Stream stream = webresponse.GetResponseStream();
            using (StreamReader reader = new StreamReader(stream))
            {
                Console.WriteLine(reader.ReadToEnd());
            }
        }
    }
    catch (WebException webEx)
    {
        Console.WriteLine("Web exception :" + webEx.Message);
    }
    catch (Exception ex)
    {
        Console.WriteLine("Exception :" + ex.Message);
    }

根据我得到的错误，我假设它找不到文件或者我的web.config设置不正确？有什么新想法吗？

通过将绑定从BasicHttpBinding更改为WebHttpBinding，并将安全模式从Transport更改为None（更新了web.config），最终实现了该功能。我仍然不确定为什么会出现404 Not found错误，但我首先删除了BasicAuthorization模块，并重新测试了该服务，确保我可以从内部和外部访问它。之后，我实现了webHttpBinding，并将安全模式设置为None，这几乎使一切正常工作。现在我有了一个具有基本身份验证的完整功能的WCF服务。希望这能帮助那些和我一样的人。
