c# - WCF - 错误 : Cannot obtain Metadata

Question

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:

Error: Cannot obtain Metadata from http://localhost:53867/MyAPI.svc If this is a Windows (R) Communication Foundation service to which you have access, please check that you have enabled metadata publishing at the specified address.
For help enabling metadata publishing, please refer to the MSDN documentation at http://go.microsoft.com/fwlink/?LinkId=65455.WS-Metadata Exchange Error
URI: http://localhost:53867/MyAPI.svc
Metadata contains a reference that cannot be resolved: 'http://localhost:53867/MyAPI.svc'.
Content Type application/soap+xml; charset=utf-8 was not supported by service http://localhost:53867/MyAPI.svc.
The client and service bindings may be mismatched.
The remote server returned an error: (415) Unsupported Media Type.HTTP GET Error
URI: http://localhost:53867/MyAPI.svc
The HTML document does not contain Web service discovery information.

这是我的一些 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>

我不知道是什么原因造成的？我的成员(member)提供者在那个位置，它有正确的命名空间。

Answer 1

从

中删除名称属性

   <behavior name="MyServiceBehavior"> 

从

   <binding name="MembershipBinding">

并添加 serviceMetadata 元素

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

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