Anvil Q&A

Hi,
I use “anvil.http.request” to access my host, but got “hostnam: Name or service not known”, any ideas why this happen?

Hi there, and welcome to the forum!

Can you post the code you’re using? How are you calling anvil.http.request()?

Thanks for your reply, here is the code:
import anvil.http

@anvil.server.callable
def do_login(url, name, pwd):
r = anvil.http.request(url, method=‘POST’, data={“username”:name, “pwd”:pwd}).get_bytes()
…

What url are you passing in?

That error message looks like you’re using a URL like "http://hostnam/", and it’s (rightly) complaining that it can’t find a web address called "hostnam".

Sorry for mislead, the hostname just a placeholder, it represents my server host name. The actual error message is “My server url: Name or service not known”. The url is my server url. I try in my side, it works fine.
