c# - WCF 中的会话不一致

Question

我正在尝试在我的 WCF 服务 (webHttp) 中使用会话，但请求之间的会话不一致（当我第二次调用服务时会话不是 NULL，但我插入的密钥不存在并且会话身份证不同）。

我检查了默认的 InstanceContextMode 是 PerSession，据我了解，这应该适合我的要求。

在 WCF 中使用会话是否需要任何其他配置？

谢谢！

You need to use a binding that supports reliable sessions, such as these:

• HTTP-based transport standard bindings:

  WsHttpBinding and expose request-reply or one-way contracts.

  Can be used when using reliable session over a request-reply or simple one-way service contract.

  WsDualHttpBinding and expose duplex, request-reply, or one-way contracts.

  WsFederationHttpBinding and expose request-reply or one-way contracts.

• TCP-based transport standard bindings:

  NetTcpBinding and expose duplex, request reply, or one-way contracts.
