Hung Jung Lu , Along these same lines, I have a C++ CGI App that I would like to call from zope. It requires a couple of parameters. The app can either return HTML or I can have it save the output to a text file. Ultimately, the text will need to be displayed to the user from Zope. Q1. How does one call a C++ CGI program from Zope? Q2. How do you supply the C++ CGI program with "command line" parameters from Zope when making the call?
From Python (either an ExternalMethod or a product)::
import sys, os, string def ExecCGI( cmdLine ): """ Run an external command and return its standard output as a string. """ f = os.popen( cmdLine ) # note that Win32 has a non-standard popen() lines = f.readlines() status = f.close() if status: raise "CGI returned error: %d" % status[1] return string.join( lines ) To call it from DTML, passing the current values of 'foo' and 'bar':: <dtml-let cmdLine="'/path/to/my/cgi %s %s' % ( foo, bar )"> <dtml-var "ExecCGI( cmdLine )"> </dtml-let> Tres. -- ========================================================= Tres Seaver tseaver@palladion.com 713-523-6582 Palladion Software http://www.palladion.com
