C# Web服务终结点标识错误

我对我们的web服务有问题。我们没有制作web服务，所以我们不知道到底发生了什么。起初，它在我们的服务器上工作，但有时不工作，这导致我们重新启动它。现在，它显示错误消息：

无法打开安全通道，因为与远程终结点的安全协商失败。这可能是由于用于创建通道的EndpointAddress中缺少EndpointIdentity或未正确指定EndpointIdentity造成的。请验证EndpointAddress指定或暗示的EndpointIdentity是否正确标识远程端点

但是我们的web服务甚至都不安全！我们的网络配置是：

在安全标签下，尝试以下操作

<security mode="None">  

<transport clientCredentialType="Windows" proxyCredentialType="None" realm="" />  

<message clientCredentialType="Windows" negotiateServiceCredential="true" establishSecurityContext="true" />  

</security>

终于找到了答案！基本上，在asp.net应用程序web.config的System.Servicemodel绑定下，我应该添加：

<security mode="None"/>

它被删除了，因为我正在玩web服务身份验证的代码。感谢上帝，我有多个备份！谢谢大家！我将在两天后更新此答复。

我们已修复

旧代码

<security mode="TransportWithMessageCredential">
    <transport clientCredentialType="None" />
    <message establishSecurityContext="false" />
</security>
   

<security mode="TransportWithMessageCredential">
    <transport clientCredentialType="None" proxyCredentialType="None" realm="" />
    <message clientCredentialType="UserName" negotiateServiceCredential="true" algorithmSuite="Default" establishSecurityContext="false" />
</security>  

新代码

<security mode="TransportWithMessageCredential">
    <transport clientCredentialType="None" />
    <message establishSecurityContext="false" />
</security>
   

<security mode="TransportWithMessageCredential">
    <transport clientCredentialType="None" proxyCredentialType="None" realm="" />
    <message clientCredentialType="UserName" negotiateServiceCredential="true" algorithmSuite="Default" establishSecurityContext="false" />
</security>  

我尝试了您的解决方案，但它仍然会抛出该错误。有一件事总是好的，那就是检查不同配置属性的默认值，因为它们适用于您正在使用的绑定<例如，code>wsHttpBinding的默认安全模式为

Message

，而

basicHttpBinding

的默认安全模式为

None

（IIRC），而

netTcpBinding

的默认安全模式为

Transport

。如果未在配置（或代码）中指定值，则使用默认值。
