注解

每个邻近设备一次只能发布一个 URI。

可以通过将 PublishUriMessage 方法返回的发布 ID 传递给 StopPublishingMessage 方法来停止发布 URI。

与邻近设备的其他发布方法不同，URI 发布由 URI 的默认协议处理程序处理。不需要订阅 URI 消息发布。可以通过注册 URI 协议（如 HTTP 协议）的默认处理程序来接收 URI 消息。

发送应用程序的 PackageFamilyName 值随 URI 一起自动发送。如果没有为 URI 的协议注册处理程序，则发送应用程序的 PackageFamilyName 值用于将接收应用程序定向到应用程序存储。

可以使用 PublishMessage 方法将文本消息发布到近似计算机。可以使用 PublishBinaryMessage 方法发布非文本消息或符合 NDEF 消息标准的消息。

重要

邻近感应 API 不提供身份验证、加密或消息完整性。不要使用邻近感应来交换用户敏感信息，如密码、财务数据、短信、电子邮件、照片或政府 ID 号。
