[英]Microsoft WCF test client Error
我是 WCF 服務的新手。 我瀏覽了一些教程,得到了一個簡單的程序,並嘗試在 C# 中的 WCF 服務應用程序中執行。 代碼如下所示。
服務1.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;
namespace WcfService1
{
[ServiceContract]
public interface IService1
{
int calculatedays(int day,int month,int year);
}
}
服務1.svc.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;
namespace WcfService1
{
public class Service1 : IService1
{
public int calculatedays(int day, int month, int year)
{
DateTime dt = new DateTime(year, month, day);
int datetodays = DateTime.Now.Subtract(dt).Days;
return datetodays;
}
}
}
網頁配置
<?xml version="1.0"?>
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.0" />
</system.web>
<system.serviceModel>
<behaviors>

<behavior>
<!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->

當我運行應用程序時,它給出的錯誤是
錯誤:無法從http://localhost:2049/Service1.svc獲取元數據 如果這是您有權訪問的 Windows (R) Communication Foundation 服務,請檢查您是否已在指定地址啟用元數據發布。 有關啟用元數據發布的幫助,請參閱 MSDN 文檔,網址為http://go.microsoft.com/fwlink/?LinkId=65455.WS-Metadata Exchange Error URI: http://localhost:2049/Service1.svc Metadata contains無法解析的引用:“ http://localhost:2049/Service1.svc ”。 服務器沒有提供有意義的回復; 這可能是由於合同不匹配、會話過早關閉或內部服務器錯誤造成的
創建 One Host 並在 host 程序中添加 appconfig 文件。然后在 appconfig 中編寫以下代碼。
<?xml version="1.0"?>
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.5" />
<httpRuntime targetFramework="4.5" />
</system.web>
<system.serviceModel>
<services>
<service name="WcfService1.Service1" behaviorConfiguration="maxBehaviour">
<endpoint address="WcfService1" binding="netTcpBinding" contract="WcfService1.IService1">
</endpoint>
<host>
<baseAddresses>
<add baseAddress="http://localhost:2049/"/>
<add baseAddress="net.tcp://localhost:8090/"/>
</baseAddresses>
</host>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="maxBehaviour">
<serviceMetadata httpGetEnabled="true"/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>
</configuration>
將 Wcfservice1 項目的 Reference 添加到該項目中。創建一個類並編寫以下代碼
public static void Main()
{
using (ServiceHost host = new ServiceHost(typeof(WcfService1.Service1)))
{
host.Open();
Console.WriteLine("Started Report Host");
Console.ReadKey();
}
}
