yeah hURL is a mess .. took me long time to understand back then
here is an example who will receive 404
Code: Select all
@REQUIRE "hurl"
; this function will be called whenever there is new data
Function p_WriteData(data$)
DebugPrint(data$)
EndFunction
; create easy object and configure it
e = hurl.Easy({URL = "https://www.google.com/NONEXISTING", WriteFunction = p_WriteData})
e:setopt_http_version(#CURL_HTTP_VERSION_1_1)
e:setopt_customrequest("GET")
e:perform()
; destroy easy object
responsecode = e:getinfo_response_code()
e:close()
DebugPrint("error code : "..responsecode)
End

Yes, MorphOS open an output window with the content of the URL (file).

Did you remove the debug output from the write function too? In any case there's no output window by default.

@jPV: yes...
This is a code wich normally just show responsecode:
Code: Select all
@REQUIRE "hurl"
e = hurl.Easy({URL = "https://www.google.com"})
e:perform()
responsecode = e:getinfo_response_code()
e:close()
DebugPrint("error code : "..responsecode)
End
I have many caracters before the responsecode on MorphOS...

If you don't provide a write function, it will output to stdout (shell). So it works as it should and if you don't want any output or store any data to anywhere, give it a function that does nothing.
This is a very minimal example:
e = hurl.Easy({URL = "
https://www.google.com", WriteFunction = Function() EndFunction})
Here's what's told in the libcurl manual (googled it):
"libcurl offers its own default internal callback that takes care of the data if you do not set the callback with CURLOPT_WRITEFUNCTION. It simply outputs the received data to stdout."
