Question

我的wcf重置服务只有2个合同，一个总是工作，另一个不起作用。

服务代码：

Public Class BasicServ
     Implements IBasicServ

        Public Function DoWork() Implements IBasicServ.DoWork
            Return "Working"
        End Function

        Function Authorize(ByVal id As String, ByVal pw As String) Implements IBasicServ.Authorize
            Dim c As New List(Of Guid)
            For i = 0 To 10
                c.Add(Guid.NewGuid)
            Next
            Return c
            'Return Guid.NewGuid
        End Function
    End Class

合同文件代码：

<ServiceContract()>
Public Interface IBasicServ

    <OperationContract()>
    <WebGet(UriTemplate:="test/", BodyStyle:=WebMessageBodyStyle.Wrapped, RequestFormat:=WebMessageFormat.Json, ResponseFormat:=WebMessageFormat.Json)>
    Function DoWork()

    <OperationContract()>
    <WebGet(UriTemplate:="Authorize/{id}/{pw}", BodyStyle:=WebMessageBodyStyle.Wrapped, RequestFormat:=WebMessageFormat.Json, ResponseFormat:=WebMessageFormat.Json)>
    Function Authorize(ByVal id As String, ByVal pw As String)


End Interface

Web配置文件：

      -->
    <directoryBrowse enabled="true"/>
  </system.webServer>

</configuration>

在调试/测试时，我发现，如果我在Authoriza方法中只返回1个GUID，它就可以了，但是当我发送GUID列表时，它无法正常工作，并且没有创建SVClog文件。能否帮助我更好地了解WCF REST服务？谢谢。

Answer 1

从上面的评论和几个实验中，问题的解决方案是，如果返回类型是字符串，则不是必需的，但如果是其他任何内容，则必须指定返回类型。如果始终提供返回类型，则更好。
