Calling functions remotely
You can use the Uplink to call functions on your own machine—or anywhere else, like a cloud server or IoT device. You can also call functions in your Anvil Server Modules from these external scripts.
Anvil -> your machine
To use the Anvil Uplink library in your Python project, first run pip install anvil-uplink on your machine.
Your local Python code can now do anything a Server Module can do.
Mark functions with @anvil.server.callable if you want to call them from your app.
# In a script on your own machine (or anywhere)
import anvil.server
anvil.server.connect("<your Server Uplink key>")
@anvil.server.callable
def get_file():
# Return a file from this local machine
return anvil.media.from_file("./image.jpg", "image/jpeg")
anvil.server.wait_forever()Your machine -> Anvil
You can also call functions in your Anvil Server Modules from your uplinked code. This makes the Uplink a two-way connection: your app can run code on your machine, and your machine can call back into your app.
# This is a simple program that makes a call to a server module.
import anvil.server
anvil.server.connect("<your Uplink key>")
anvil.server.call("store_number", 42)This example does not register any @anvil.server.callable functions, and exits as soon as the call to store_number returns.
