Question

我有另一个与WCF相关的问题，虽然这看起来相对简单。

我有一个看起来像这样的方法：

[OperationContract()]
        [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Bare, RequestFormat = WebMessageFormat.Json, UriTemplate = "/BS/vFacility/{vFacility}/vAdress/{vAdress}/vPostalNr/{vPostalNr})]
        string BS(string vFacility, string vAdress, string vPostalNr);

如果我这样称呼它，这是有效的：

/BS/vFacility/Oven/vAdress/Boulevard 25/vPostalNr/6749

但我希望用户能够通过网址调用此方法，然后不输入，就像地址一样：

/BS/vFacility/Oven/vAdress//vPostalNr/6749

在这种情况下，如果可能的话，我希望忽略的参数设置为null。如果我尝试上面的网址，我会收到一条消息，指出“找不到端点”

这是我的web.config：

<?xml version="1.0"?>
<configuration>

  <appSettings>
    <add key="aspnet:UseTaskFriendlySynchronizationContext" value="true" />
  </appSettings>
  <system.web>
    <compilation debug="true" targetFramework="4.6.1"/>
    <pages validateRequest="false" />
    <httpRuntime targetFramework="4.6.1"/>
  </system.web>
  <system.serviceModel>
    <behaviors>
      <serviceBehaviors >
        <behavior name="ServiceBehavior">
          <!-- To avoid disclosing metadata information, set the values below to false before deployment -->
          <serviceMetadata httpGetEnabled="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>
      </serviceBehaviors>
      <endpointBehaviors>
        <behavior name="web">
          <webHttp/>
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <services>
      <service name="WCFBolig.Service1" behaviorConfiguration="ServiceBehavior">
        <endpoint binding="webHttpBinding" 
                  contract="WCFBolig.IService1"
                  behaviorConfiguration="web"/>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
      </service>
    </services>
    <serviceHostingEnvironment  multipleSiteBindingsEnabled="true" />
  </system.serviceModel>
  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
    <!--
        To browse web app root directory during debugging, set the value below to true.
        Set to false before deployment to avoid disclosing web app folder information.
      -->
    <directoryBrowse enabled="true"/>
  </system.webServer>
  <connectionStrings>
    <add
      name="UnikBoligCon"
      connectionString="server=XX;database=XX;user=XX;password=XX"
      providerName="System.Data.SqlClient"
  />
  </connectionStrings>
</configuration>

这是可能的还是用户被迫为所有参数提供输入？

Answer 1

我只需要了解一下URI来做到这一点。结果我不得不改变它：

/BS/vFacility/{vFacility}/vAdress/{vAdress}/vPostalNr/{vPostalNr}

To This：

/BS?vFacility={vFacility}&vAdress={vAdress}&vPostalNr={vPostalNr}

现在我可以简单地忽略参数，它仍然有效。必须确保SQL代码仍然可以使用空值。

F.eks。像这样的网址（http://localhost/BAlias/Service1.svc/BS？）或者这个（http://localhost/BAlias/Service1.svc/BS?vAdress=Whateverroad）现在工作得很好。

WCF url允许用户不输入参数
