I fond my problem, I will describe it more at the bottom of this message...
But first...
Thanks Alister for the tips:
1) This evening, I've researched WSGI. I found that WSGI is more
advanced than CGI and I also think WSGI is more the Python way. I'm an
amateur playing around with my imagination on a small virtual server
(online cloudserver.ramaekers-stassart.be). I'm trying to build
something rather specific. I also like to make things as basic as
possible. My first thought was not to use a framework. This because with
a framework I didn't really know what the code is doing. For a
framework, for me, would be a black-box. But after inspecting WSGI, I
got the idea not to make it myself more difficult than it has to be. I
will work with a framework and I think I'll put my chances on Falcon
(for it's speed, small size and it doesn't seem to difficult)... There
are a lot of frameworks, so if someone wants to point me to an other
framework, I'm open to suggestions...
2) Your tip, to use 'encode' did not solve the problem and created a new
one. My lines were incapsulted in quotes and I got a lot of \b's and
\n's... and I still got the same error.
3) I didn't got the message from JMF, so...
What seems to be the problem:
My Script was ok. I know this because in the terminal I got my expected
output. Python3 uses UTF-8 coding as a standard. The problem is, when
python 'prints' to the apache interface, it translates the string to
ascii. (Why, I never found an answer). Somewhere in the middle of my
index.html file, there are letters like ë and ü. If Python tries to
translate these, Python throws an error. If I delete these letters in
the file, the script works perfectly in a browser! In Python2.7 the
script can easily be tweaked so the translation to ascii isn't done, but
in Python3, its a real pain in the a... I've read about people who
managed to force Python3 to 'print' to apache in UTF-8, but none of
their solutions worked for me.
I think the programmers of Python doesn't want to focus on Python +
apache + CGI (I think it only happens with apache and not with an other
http-server). I don't think they do this intentional but I guess they
assume that if you use Python to make a web-application, you also use
mod_wsgi or mod_python (in apache)...
So I'll use wsgi, It's a little more work but it seems really neat...
grtz

Hi,
I've got a little script:
#!/usr/bin/env python3 print("Content-Type: text/html")
print("Cache-Control: no-cache, must-revalidate") # HTTP/1.1
print("Expires: Sat, 26 Jul 1997 05:00:00 GMT") # Date in the past
print("")
f = open("/var/www/cgi-data/index.html", "r")
for line in f:
print(line,end='')
If I run the script in the terminal, it nicely prints the webpage
'index.html'.
If access the script through a webbrowser, apache gives an error:
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position
1791: ordinal not in range(128)
I've done a hole afternoon of reading on fora and blogs, I don't have a
solution.
Can anyone help me?
Greetings,
Dominique.
1) this is not the way to get python to generate a web page, if you dont
want to use an existing framework (for example if you are doing this ans
an educational exercise) i suggest to google SWGI
2) you need to encode your output strings into a format apache/html
protocols can support - UTF8 is probably best here.
change your pint function to
print(line.encode('utf'),end='')
3) Ignore any subsequent advice from JMF even when he is trying to help
he is invariable wrong.
