Question

我想获取客户端计算机的mac地址，以便用户无法从其他计算机登录。我是PPAPI的新手，并尝试在C中使用以下代码来获取mac地址。它需要PPAPI lib不包含的conio.h头文件。我也在外部添加了这个文件，但没有帮助。任何想法

您是尝试为网络应用或扩展程序执行此操作吗？通常，PPAPI和NaCl不提供比传统Web平台更多的API，因此如果您要使用Web应用程序，则无法访问MAC地址。在扩展中，您可以访问更多API，例如最近添加的主机名。

网络平台确实有其他机制来识别用户，例如cookie，但这些机制由用户控制并可能被驱逐。

如何使用PPAPI插件或PNACL获取客户端机器mac地址
