运行进程间通信dbus服务程序和客户程序时报错：

Couldn't connect to session bus: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

原因：

不能在root用户下运行，（可能这创建的是session dbus的原因，而不是system dbus），用exit退出root用户到普通用户下运行就好了
