Device-MojoMsgSample部分代码- /* This is a sample app that shows how to use the mojo messaging service.
- The app works in tandem with a cloud push app that runs at TODO.
- The first time this app is launched it creates an endpoint for itself
- and lets the clould app know about it. The cloud app also creates a
- device id to identify your device. It also has a web UI interface
- that lets you put your device id and push messages to your device.
- You can use some kind of login mechanism or the device nduid (see SDK)
- to uniquely identify a device from your cloud app. */
