I am trying to display the contents of /etc/postfix/transport.in in a <div> via python & cgi. When I run the script from the command line it works as I would expect, however, when called from the webpage it does not display the file contents. This is what I have in my CGI:
#!/usr/bin/env python
import cgi, os.path
# fileName = "/etc/postfix/transport.in"
form = cgi.FieldStorage()
fileName = form['file'].value
def safePlainText(s):
newString = s.replace('&', '&').replace('<', '<')
return newString
def fileLinesToHTMLLines(fileName):
safeLines = list()
if os.path.exists(fileName): # test if the file exists yet
lines = fileToStr(fileName).splitlines()
for line in lines:
safeLines.append(safePlainText(line))
return safeLines
def fileToStr(fileName):
fin = open(fileName);
contents = fin.read();
fin.close()
return contents
lines = fileLinesToHTMLLines(fileName)
print "Content-type:text/htmlrnrn"
print "<html>"
print "<head>"
print "<title>Data File %s</title>" % fileName
print "</head>"
print "<body>"
print "<ul>"
for line in lines:
print "<li> %s </li>" % str(cgi.escape(line))
print "</ul>"
print "</body>"
print "</html>"
Everything (HTML Tags incl. title) comes through as expected with the exception of the lines of the file I am trying to display. Firebug shows the response from the server as being:
<html>
<head>
<title>Data File transport.in</title>
</head>
<body>
<ul>
</ul>
</body>
</html>
However if I run the script from the command line I get:
# sudo -u apache ./test3.py
Content-type:text/html
<html>
<head>
<title>Data File /etc/postfix/transport.in</title>
</head>
<body>
<ul>
<li> host.domain.com relay:[mailhub.domain.corpnet1] </li>
<li> * relay:[host.mailrelay.com] </li>
</ul>
</body>
</html>
I am sure that it is something simple, but for the life of me I cannot figure it out...
I am running Python 2.7.5 / Apache 2.4.6 on RHEL7.
