WCF 中的 EndpointNotFoundException

Question

我盯着web.config看了很久，你们能看看吗？

运行 service.Endpoint.Address.ToString() 给了我预期的结果：http://localhost:2867/Service1.svc 和 http://localhost:2867/Service1.svc?wsdl 给了我需要的所有方法。

如果您需要更多信息/代码，我很乐意添加。

感谢观看！

错误

http://localhost:2867/Service1.svc 上没有可以接受消息的端点侦听。这通常是由不正确的地址或 SOAP 操作引起的。

      </service>
    </services>

Answer 1

要检查两件事：

1. 您的客户端正在使用basicHttpBinding，而您的服务正在使用webHttpBinding，因此您的绑定不匹配。

2. 您的客户端引用 ServiceReferenceCDP.IService1 的合约，而您的服务使用 CollectiveDistributedPolling.IService1 - 即使代码相同，它们也不相同。

记住 WCF 的 ABC - 地址、绑定和合同。客户端必须匹配服务才能连接。

Answer 2

你的服务器端配置地址属性只包含一个空字符串，在里面指定一个地址：http://localhost:2867/Service1.svc

（请不要为此使用开发服务器。）
