使用cgi-python脚本设置co​​okie

Question

I'm trying to response from the server with a set-cookie header

my cgi script begins as follows

#!/usr/bin/env python

import json
from collections import defaultdict
import cgi
import cgitb; cgitb.enable()  # for troubleshooting
from MySQL import sql

form = cgi.FieldStorage()
mode = form.getvalue('mode')

print """Content-type: text/html\r\n"""
print """Set-Cookie: name=12345\r\n\r\n"""

However, when checking the response from the server on my Chrome..the debugger doesn't show any set-cookie header in the response part, and the set-cookie header is printed in the response part as part of the text, unlike the content-type header...

Any idea what I did wrong?

Thanks guys

Answer 1

The problem is that you are appending two newlines instead of one to the end of your "Content-Type" header, which is the standard separator between HTTP headers and body.

You should instead be emitting \\r\\n at the end of each header value (as opposed to \\n\\n )

When you are done emitting headers, you should print one extra \\r\\n to begin your message body.

EDIT: Additionally, you should either be using sys.stdout.write(...) or appending a trailing comma to your print statement to avoid its inserting the implicit newline. Eg,

print "Header: Value\\r\\n",

您应该在Content-type：text / html行之前打印Set-Cookie行。
