WCF 拒绝将客户端凭据附加到请求

Question

我有一个正在尝试与之交互的网络服务，但是无论我尝试什么，它都拒绝随请求一起发送客户端凭据。

我的 app.config 中的安全块看起来像

<security mode="Transport">
    <transport clientCredentialType="None" proxyCredentialType="None" realm="" />
    <message clientCredentialType="UserName" algorithmSuite="Default" />
</security>

然后我像这样使用服务代理：

Dim MyUploadEvent As New EventUploadWSv1.EventUploadWSv1PortTypeClient("IEventUploadWSv1Port")
Dim request As New EventUploadWSv1.webservice_source_event_FileUploadRequest

' First Thing I tried
MyUploadEvent.ClientCredentials.UserName.UserName = "..."
MyUploadEvent.ClientCredentials.UserName.Password = "..."

' Also Tried this based on a question here and a couple of blogs
'Dim defaultCredentials As ClientCredentials
'Dim loginCredentials As New ClientCredentials()

'loginCredentials.UserName.UserName = "..."
'loginCredentials.UserName.Password = "..."

'defaultCredentials = MyUploadEvent.Endpoint.Behaviors.Find(Of ClientCredentials)()
'MyUploadEvent.Endpoint.Behaviors.Remove(defaultCredentials)
'MyUploadEvent.Endpoint.Behaviors.Insert(0, loginCredentials)

' Configure Request Object

' This throws an exception
MyUploadEvent.fileUpload(request)

我还尝试使用其他所有 ClientCredentials 字段（MyUploadEvent.ClientCredentials 和 MyUploadEvent.ClientFactory.ClientCredentials），但服务器不断返回一条消息，告诉我没有 SOAP附有认证信息。我检查了通过网络发送的消息，没有任何地方提到用户名或密码。我显然在这里遗漏了一些我不应该遗漏的东西。

您必须使用 TransportWithMessageCredential 安全模式。 Transport 仅使用 Transport 元素中定义的配置，而 Message 元素被完全忽略。
