f = open（）/可在命令行中使用，但不能作为CGI脚本[python]

Question

    #! /usr/bin/env python

import htmlSplitter, htmlGlue

headerContent, mainContent, sideSetup, sideContent, footerContent = htmlSplitter.split("../htdocs/bcc/register.html")


mainContent = "<h1>This is another Test</h1>"
sideContent = "<h2>Jonathan's here!</h2>"


htmlDoc = htmlGlue.glue(headerContent, mainContent, sideSetup, sideContent, footerContent)

f = open("../bcc/doctest.html", "w")
f.write(htmlDoc)
f.close()

print("Location:../bcc/doctest.html")
print

this script works perfectly when I run it from the command line. However, when I run it as a CGI script, it gives me a "premature end of script headers" error. I've debugged and it's fine if I comment out the segment that opens and writes "doctest.html" (so I know that the other two modules I've included are not causing the problem). Any idea why that part of the code doesn't work as a CGI script? Is there something I should be substituting instead?

NOTE: I've done a chmod a+rw on 'doctest.html' to make sure that the script has permissions to edit.

Thanks!

Answer 1

Maybe just a copy/paste-error, but your shebang seems to be indented. unindent it, and try to start the script via command line on the server, using ./yourscript (not python yourscript , as this is how it probably gets executed by the webserver)

Answer 2

Add the following to the beginning of your script:

#!/usr/bin/env python
print 'Content-Type: text/html'
print

I've always declared the Content-Type in my python cgi scripts, it's polite.

import cgi
import cgitb
cgitb.enable() # allows error tracebacks

cgitb will show you a nice web based traceback if something went wrong with your script, such as any exceptions thrown.
