重要
使用不受信任的数据从实现此接口的类中调用方法存在安全风险。Calling methods from classes that implement this interface with untrusted data is a security risk. 仅使用受信任的数据从实现此接口的类中调用方法。Call the methods from classes that implement this interface only with trusted data. 有关详细信息,请参阅数据验证。For more information, see Data Validation.
通道的发送端必须公开 IChannelSender 接口。The sending side of channels must expose the IChannelSender interface.
属性
| ChannelName |
获取信道的名称。Gets the name of the channel. (继承自 IChannel) |
| ChannelPriority |
获取该信道的优先级。Gets the priority of the channel. (继承自 IChannel) |
方法
| CreateMessageSink(String, Object, String) |
返回将消息传送到指定 URL 或信道数据对象的信道消息接收器。Returns a channel message sink that delivers messages to the specified URL or channel data object. |
| Parse(String, String) |
将对象 URI 返回为输出参数,将当前信道的 URI 返回为返回值。Returns the object URI as an out parameter, and the URI of the current channel as the return value. (继承自 IChannel) |
