是否有一种特定的方法来获取Pharo smalltalk中的计算机的IP？

Question

I am trying to run an application Pharo that requires data from the Ip of the host computer in which it's running. In general I have to open the code to set it manually in my Pharo code then launch the application. Is there a better and programmatically way of getting the IP address and returning this address automatically regardless of the computer? Say I deploy it to different computer.

Answer 1

I think you are searching for NetResolverName .

To get name of your computer:

NetNameResolver localHostName

Then you can use it for the IP address. If you execute in Workspace:

NetNameResolver addressForName: NetNameResolver localHostName

You will get a local network address.

In my case: #[192 168 1 17]

Edit

You can also directly query it via:

NetNameResolver localAddressString

Where you will get just: '192 168 1 17'

Note: If you are getting 127.0.0.1

If you are getting localhost address => 127.0.0.1 you probably have issues with the host mapping.
You can test that with via ping "hostname" eg ping localhost.localdomain which will get you replies from 127.0.0.1 . If you have correct setup (hosts, DNS, etc.) you should get reply from your IP address.

When I have changed the hostname from localhost.localdomain to smalltalk then ping smalltalk correctly replies with 192.168.10.30 . Then Pharo produces correct result.
