Determine if Python script is being executed locally or as CGI
Let's say I have a basic Python script, test.py:
#!/usr/bin/python
print "Content-type: text/html\n\n"
print "<html>Hello world!</html>"
How would one determine if the script is being executed locally, e.g.:
python test.py
Or being called via a web browser, e.g. visiting:
http://example.com/test.py
This doesn't seem to be addressed in the documentation for the开发者_JAVA技巧 cgi module. I thought there might be a difference in the result of cgi.FieldStorage() but there doesn't seem to be one.
The only way I can think to do it is as follows:
#!/usr/bin/python
import os
print "Content-type: text/html\n\n"
print "<html>Hello world!</html>"
if 'REQUEST_METHOD' in os.environ :
print "This is a webpage"
else :
print "This is not a webpage"
Is this the best and/or most ideal method? Why/why not?
That looks like the best method. There isn't much difference between being called from the command-line and being started by the web server following a HTTP request, except for the CGI environment variables, like REQUEST_METHOD.
