http://msdn.microsoft.com/en-us/magazine/dd315413.aspx如何調用WCF服務方法

在本教程中,我們可以直接從瀏覽器中得到通過GET方法的數據,如下圖: http://i.msdn.microsoft.com/dd315413.fig06_L%28en-us%29.gif

這裏是:

[OperationContract] 
    [WebGet(UriTemplate = "/{year}")] 
    IssuesData GetIssuesByYear(string year); 

我在我的項目中有類似的方法:

[ServiceContract] 
public interface IRegistrationService 
{ 
    [OperationContract] 
    [WebGet(UriTemplate = "/GetUser/{number}")] 
    Users GetUsers(string number); 
} 

但是,當我在瀏覽器中鍵入

本地主機:26451/RegistrationService.svc /的getUser/1

沒有什麼..它沒有調用方法(用調試器檢查)。另一方面,來自msdn的例子很好,並且調用了該方法。

出了什麼問題?

我敢打賭,在web.config文件中有一些情況。這是我的webconfig:

<configuration> 
     <configSections> 
     <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 --> 
     <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=5.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />

     </appSettings>

       <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" /> 
       <!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid disclosing exception information --> 
       <serviceDebug includeExceptionDetailInFaults="false" /> 
      </behavior>

     </behaviors>

      <add binding="basicHttpsBinding" scheme="https" />

     <!--

      Set to false before deployment to avoid disclosing web app folder information. 
      --> 
     <directoryBrowse enabled="true" /> 
     </system.webServer> 
     <entityFramework> 
     <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework" /> 
     </entityFramework> 
    </configuration>

我應該改變些什麼呢?

你實施了IRegistrationService嗎? – Kaf

@卡夫當然。 – whoah

我認爲你在web.config中缺少端點 – Dimitri

web.config中沒有配置端點。對於這個特定的例子POX(webhttpbinding)端點應該被配置。

必須使用webHttpBinding創建WCF休息服務

因爲在MSDN的例子中,沒有終點,則使用默認的端點。在這種情況下,默認使用webHttpBinding。

爲什麼不擺脫你的端點定義,看看會發生什麼。
