问题描述

当我尝试从 WCF 测试客户端运行我的应用程序时，我收到以下错误:

When I try to run my application from the WCF Test Client I receive the following error:

这是我的一些 web.config:

Here is some of my web.config:

    <system.web>
    <compilation debug="true" targetFramework="4.0">
        <assemblies>
            <add assembly="System.Data.Entity, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
        </assemblies>
    </compilation>
    <membership defaultProvider="CustomMembershipProvider">
        <providers>
            <clear/>
            <add name="CustomMembershipProvider" type="Namespace.Models.MyMembershipProvider" />
        </providers>
    </membership>
</system.web>
<system.serviceModel>
    <bindings>
        <wsHttpBinding>
            <binding name="MembershipBinding">
                <security mode ="Message">
                    <message clientCredentialType="UserName"/>
                </security>
            </binding>
        </wsHttpBinding>
    </bindings>
    <behaviors>
        <serviceBehaviors>
            <behavior name="MyServiceBehavior">
                <serviceCredentials>
                    <userNameAuthentication
                    userNamePasswordValidationMode="MembershipProvider"
                    membershipProviderName="CustomMembershipProvider" />
                </serviceCredentials>
            </behavior>
        </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment multipleSiteBindingsEnabled="true" aspNetCompatibilityEnabled="true" />
</system.serviceModel>

我不知道是什么导致了这种情况?我的会员资格提供商位于该位置，并且具有正确的命名空间.

I've no idea what could be causing this? My Membership Provider is in that location and it has the correct namespace.

推荐答案

从

   <behavior name="MyServiceBehavior"> 

来自

   <binding name="MembershipBinding">

并添加 serviceMetadata 元素

and add serviceMetadata element

    <behaviors>
        <serviceBehaviors>
            <behavior>
                <serviceMetadata httpGetEnabled="True"/>
                <serviceCredentials>
                <userNameAuthentication
                    userNamePasswordValidationMode="MembershipProvider"
                    membershipProviderName="CustomMembershipProvider" />
                </serviceCredentials>

            </behavior>
        </serviceBehaviors>
    </behaviors>
