如何从浏览器访问WCF服务的方法呢？ [英] How to access WCF service methods from browser?
问题描述
这是这是在Visual Studio 2013在默认情况下向导创建一个code。
在项目属性我设置为使用本地IIS。
WCF测试客户端成功地对其进行测试。
但是，如果我访问页
HTTP：//localhost/WcfService1/Service1.svc/GetTime
在浏览器的话，我看空浏览器屏幕和小提琴手显示HTTP / 1.1 400错误的请求。
我知道我需要修改web.config文件，并在接口中的方法属性，但是不知道怎么办。你可以帮帮我吗？谢谢你。

感谢您sakir和蒂姆，你的评论让我寻找在适当的地方的答案。是的，这是SOAP服务，因此我需要通过网络的HTTP，以重新配置它来访问。
- 我说的这种行为，让HttpBinding在web.config中节的行为，并配置
- 我添加的属性[WebGet]来，我想在浏览器中，使可见的方法。
请注意：类似的结果，我们可以在Visual Studio中得到的，如果我们将通过空项目将创建WCF Web服务WCF服务（阿贾克斯启用）模板（我已经很难找到在VS2013，但它是在顶部VS2012作为一个单独的项目）。这将修改web.config中为我们，并给予工作code例子（但不是基于接口）。
修改的文件，并重新配置如下web.config中：
IService1.cs
使用System.Runtime.Serialization;
使用System.ServiceModel;
使用System.ServiceModel.Web;

It's a code that was created in Visual Studio 2013 by default wizard. In project properties I set to use Local IIS. WCF Test Client test it successfully. But if I access page
http://localhost/WcfService1/Service1.svc/GetTime
in browser then I see empty browser screen and Fiddler show "HTTP/1.1 400 Bad Request". I understand that I need to modify web.config, and attributes for the method in interface but don't know how. Could you help me? Thank you.
IService1.cs
using System.Runtime.Serialization;
using System.ServiceModel;
namespace WcfService1
{
[ServiceContract]
public interface IService1
{
[OperationContract]
string GetTime();
}
}
Service1.svc.cs
using System;
namespace WcfService1
{
public class Service1 : IService1
{
public string GetTime()
{
return DateTime.Now.ToShortTimeString();
}
}
}
web.config
<?xml version="1.0"?>
<configuration>
<appSettings>
<add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
</appSettings>
<system.web>
<compilation debug="true" targetFramework="4.5" />

Thank you to sakir and Tim, you comments allow me to look for answer in proper places. Yes, this is SOAP service, so I need to reconfigure it in order to access by web http.
- I added section "behavior" and configuration of this behavior that allow HttpBinding in web.config
- I added attribute [WebGet] to the method that I want to make visible in the browser.
Note: similar result we can get in Visual Studio, if we will create WCF web service by adding in empty project "WCF Service (Ajax-enabled)" template (which I had hard time finding in VS2013, but it's on the top in VS2012 as a separate project). This will modify web.config for us, and give working code example (however not based on interface).
Modified files and reconfigured web.config below:
IService1.cs
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
namespace WcfService1
{
[ServiceContract]
public interface IService1
{
[OperationContract]
[WebGet]
string GetTime();
}
}
web.config
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<appSettings>
<add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
</appSettings>
<system.web>
<compilation debug="true" targetFramework="4.5" />
<httpRuntime targetFramework="4.5"/>
</system.web>
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior>
<serviceMetadata httpGetEnabled="true" httpsGetEnabled="true"/>
<serviceDebug includeExceptionDetailInFaults="true"/>
</behavior>
</serviceBehaviors>
**<!--added behavior-->
<endpointBehaviors>
<behavior name="WcfService1.Service1AspNetAjaxBehavior">
<enableWebScript />
</behavior>
</endpointBehaviors>**
</behaviors>
<protocolMapping>
<add binding="basicHttpsBinding" scheme="https" />
</protocolMapping>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
**<!--added service behaviour configuration-->
<services>
<service name="WcfService1.Service1">
<endpoint address="" behaviorConfiguration="WcfService1.Service1AspNetAjaxBehavior"
binding="webHttpBinding" contract="WcfService1.IService1" />
</service>
</services>**
</system.serviceModel>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true"/>
<directoryBrowse enabled="true"/>
</system.webServer>
</configuration>
