【问题描述】：
我是按照 MSDN tutorial 创建 WCF 服务的，当我运行它时，它已正确启动，但是当我按照 localhost 时，服务器是空白的。
我能做什么？
我正在使用 Chrome，我已按照许多帖子中的建议更改了设置。
ICalculator.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;
namespace GettingStartedLib
{
[ServiceContract(Namespace="http://Microsoft.ServiceModel.Samples")]
public interface ICalculator
{
[OperationContract]
double Add(double n1, double n2);
[OperationContract]
double Substract(double n1, double n2);
[OperationContract]
double Multiply(double n1, double n2);
[OperationContract]
double Divide(double n1, double n2);
}
}
计算器服务
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;
namespace GettingStartedLib
{
public class CalculatorService:ICalculator
{
public double Add(double n1, double n2)
{
double result = n1 + n2;
Console.WriteLine("Otrzymano: Add({0},{1})", n1, n2);
Console.WriteLine("Wynik: {0}", result);
return result;
}
public double Substract(double n1, double n2)
{
double result = n1 - n2;
Console.WriteLine("Otrzymano: Substract({0},{1})", n1, n2);
Console.WriteLine("Wynik: {0}", result);
return result;
}
public double Multiply(double n1, double n2)
{
double result = n1 * n2;
Console.WriteLine("Otrzymano: Multiply({0},{1})", n1, n2);
Console.WriteLine("Wynik: {0}", result);
return result;
}
public double Divide(double n1, double n2)
{
double result = n1 / n2;
Console.WriteLine("Otrzymano: Divide({0},{1})", n1, n2);
Console.WriteLine("Wynik: {0}", result);
return result;
}
}
}

库的 App.config

</appSettings>
<system.web>

<!-- When deploying the service library project, the content of the config file must be added to the host's
app.config file. System.Configuration does not support config files for libraries. -->
<system.serviceModel>
<services>
<service name="GettingStartedLib.CalculatorService">
<host>
<baseAddresses>
<add baseAddress = "http://localhost:8000/GettingStarted/CalculatorService" />
</baseAddresses>
</host>
<!-- Service Endpoints -->
<!-- Unless fully qualified, address is relative to base address supplied above -->
<endpoint address="" binding="basicHttpBinding" contract="GettingStartedLib.ICalculator">

automatically.
-->
<identity>
<dns value="localhost"/>
</identity>
</endpoint>
<!-- Metadata Endpoints -->
<!-- The Metadata Exchange endpoint is used by the service to describe itself to clients. -->
<!-- This endpoint does not use a secure binding and should be secured or removed before deployment -->
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
</service>

EDIT2：
我按照@OmegaMan 的建议使用 WCFTestClient 对其进行了测试。它给了我一个错误。
但是当我尝试地址时：http://localhost:8000/GettingStarted/（没有 CalculatorService，即使在 App.config 中这样说）它可以工作！
这是为什么呢？这很奇怪。
EDIT3： 好的，我发现我需要在*.config文件中添加“/”：
<add baseAddress = "http://localhost:8000/GettingStarted/CalculatorService" />
原来如此
<add baseAddress = "http://localhost:8000/GettingStarted/CalculatorService/" />
但是谁能告诉我为什么我的编程方法不起作用？我的意思是如果我更改 *.config 文件中的地址（或默认保留它）它永远不会工作（提到的链接服务器正常启动）
