Aurora push problem with Mac: Can not connect to Jpush Server. Please ensure your Internet connect

Recently, as a result of the project needs, using the Aurora push service, it is configured on the server side, but in the use of the official demo always error: Can not connect to Jpush Server. Please ensure your Internet connect.
caused by:java.net.UnknownHostException:api.jpush.cn but the same as the official example, and the network is no problem, how can report this error.
This is the domain name parsing error, we need to resolve this domain name in our own machine.
Workaround:

1, open the terminal:

Cd/etc

2, VI hosts

Add the Jpush IP and the corresponding hostname here.
3, after the Save exit

At this point, you will be able to send the message smoothly
