如何在 Python 中使用来自环境变量的 IP 地址加入端点

Question

I'm trying to get the Kubernetes service IP using env variable to an endpoint inside a python app.

For example in NodeJs:

(`http://${process.env.AUTH_ADDRESS}/hashed-password/` + password);

using backticks and ${} IP address is fetched from the env variable

In Python I tried

opc.tcp://"+str(os.environ.get('USER_SERVICE_SERVICE_HOST'))+":4840/

but the result is actually something like ('10.98.191.127', 4840). I need it in a format like '10.98.191.127:4840' I have tried concatenate strings individually

Answer 1

Try to convert the port 4840 to str type. Something like:

str(os.environ.get('USER_SERVICE_SERVICE_HOST'))+":"+str(4840)

Something I would do is to use f-string format, something like:

f"{os.environ.get('USER_SERVICE_SERVICE_HOST')}:4840"
