System.ServiceModel.EndpointNotFoundException：沒有端點監聽

Question

我在 Visual Studio 中有一個新的 WPF 項目。 我想連接到這個 url：“ http://www.oorsprong.org/websamples.countryinfo/CountryInfoService.wso?WSDL ”。

我已經做了一個服務參考。

當我運行它時，我收到此錯誤（我已將文本翻譯成英文）：

System.ServiceModel.EndpointNotFoundException
  HResult=0x80131501
  Message=There was no endpoint listening at http://www.oorsprong.org/websamples.countryinfo/CountryInfoService.wso, that can accept the message. This is often because of a wrong address or SOAP-action. Find more information at InnerException.
  Source=mscorlib
  StackTrace:

   at System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke(MessageData& msgData, Int32 type)

Inner Exception 1:
WebException: The underlying connection was closed: Cannot connect to remote server.

Inner Exception 2:
SocketException: There was given an illegal argument

url 與 Google Chrome 中的 Widzler 配合得很好。

代碼：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;

namespace ContactCountry
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();

            CountryConverter.CountryInfoServiceSoapTypeClient client = new CountryConverter.CountryInfoServiceSoapTypeClient("CountryInfoServiceSoap");

            myTextBox.Text = client.CapitalCity("US");
        }
    }
}

應用程序配置：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6.1" />
    </startup>

  <system.net>
    <defaultProxy enabled="false" useDefaultCredentials="false">
    </defaultProxy>
  </system.net>

  <system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="CountryInfoServiceSoapBinding" />
            </basicHttpBinding>
            <customBinding>
                <binding name="CountryInfoServiceSoapBinding12">
                    <textMessageEncoding messageVersion="Soap12" />
                    <httpTransport />
                </binding>
            </customBinding>
        </bindings>
        <client>
            <endpoint address="http://www.oorsprong.org/websamples.countryinfo/CountryInfoService.wso"
                binding="basicHttpBinding" bindingConfiguration="CountryInfoServiceSoapBinding"
                contract="CountryConverter.CountryInfoServiceSoapType" name="CountryInfoServiceSoap" />
            <endpoint address="http://www.oorsprong.org/websamples.countryinfo/CountryInfoService.wso"
                binding="customBinding" bindingConfiguration="CountryInfoServiceSoapBinding12"
                contract="CountryConverter.CountryInfoServiceSoapType" name="CountryInfoServiceSoap12" />
        </client>
    </system.serviceModel>
</configuration>

Answer 1

我發現問題在於我的 Visual Studio 解決方案位於網絡驅動器上（Windows 稱為“K”）。 當我將解決方案移至 C 驅動器時，它運行良好。

謝謝你的時間！

Answer 2

您應該將綁定名稱傳遞給構造函數。 嘗試這個

var client = new CountryConverter.CountryInfoServiceSoapTypeClient("CountryInfoServiceSoapBinding");

Answer 3

在我創建一個新控制台並測試您提供的 URL 后，它運行良好。
調用服務的代碼段和你上面貼的一樣，包括Appconfig文件中的服務端點。
結果。

兩個端點都能正常工作，我什至使用自定義綁定測試端點。

ServiceReference1.CountryInfoServiceSoapTypeClient client = new
ServiceReference1.CountryInfoServiceSoapTypeClient("CountryInfoServiceSoap12");
MyLabel.Content = client.CapitalCity("US");

因此，我懷疑您的本地網絡連接有問題。
建議你關閉本地防火牆、殺毒軟件、本地Hosts文件，使用Ping命令查明問題所在，查看該機瀏覽器能否訪問URL。
如果問題仍然存在，請隨時告訴我。
