Python scripts in IIS

[Jon Cosby]

I'm having trouble executing Python scripts in IIS. I have the error message
"%1 is not a valid Win32 application". Anyone know what this is about?

Somewhere, something is attempting to execute an application with an
argument that contains "%1", which is normally substituted with a
variable string supplied by something else. Clearly that isn't happening
here.

Without more detail, I doubt anyone can help much more. Maybe you should
post some snippets of code. Also, if the error message actually includes
more information (e.g. such as a Python traceback would have), cut and paste
the entire output rather than just retyping a part of it (if that's what you
did).

I get the same line with all of my scripts, nothing else.

Please go back and reread the previous sentence again. If you won't
provide some context, you won't likely get helpful answers.

I'll try again: *what* is giving you that error message? Some program
prints it, somewhere. Is it in a log file? Printed to the console?
In a popup dialog box? On the browser screen? What exact command did you
type just before you saw that error. Have you installed Python?
What version? etc etc etc...

Sorry. It's in the browser window. The script does not execute. I have "Show
friendly http error messages" set to false in Internet Explorer. As it
happens on all of the scripts, I can't single out one command. I have
ActiveState's build of Python 2.3, and don't recall running into this
previously, but there might be something in the IIS configuration I'm
overlooking.

Go to the Properties of the (Default) Web site, Home Directory tab,
Configuration button. On the Mappings tab, add a mapping for Python in
the form

<pathtopython>\ python.exe %s %s

Use your actual pathtopython and don't substitute anything for %s %s.

Should work fine.

Thanks. I had left out the trailing arguments. What is "%s" for, anyway?

I don't know. With MS I usually don't bother finding out if I can get
things to work.

Sorry, I just read this message. I did not the beginning of this thread.
Jon, why don't you register
Python as an ActiveX scripting language? You can download and install
pywin32 extensions:

https://sourceforge.net/projects/pywin32/

then you can run this script:

site-packages\win32c omext\axscript\ client\pyscript .py

This will register Python as an ActiveX scripting language.
Then you can create an ASP page like this (index.asp):

<%@ Language=Python %>
<%
lst = [0,1,2,3]
Response.write( str(lst))
%>

I think it is better (and faster) to use Python as an ActiveX scripting
language then to use it as a CGI program.
Best,

G

It gets substituted with the name of the .py file.

Note: you really want -

...python.exe -u %s %s

The -u ensures you get binary IO streams, which will become significant if
you are receiving file upload fields or returning a non-textual response
(ie. file download).

Can you reference the documentation for the -u argument?

Thanks.

"python -h" will show you.

Right for python, but not for IIS. E.g., in

<path>python.ex e %s %s

The first %s stands for the script name, and the second %s stands for
_all_ the arguments. This is not normal substitution. That's why %s
needs to be used, not even %S (capitalized).

Actually, Robert Brewer's response is more to the point. Security is
more troublesome with the above.

Wasn't the -u used as an option to Python in the example you were
asking about?

Andy had written this (re-posted here for reference):

Looks like a Python option to me, not an IIS one...
