问题
I\'m trying to create a super-simplistic Virtual In / Out Board using wx/Python. I\'ve got the following code in place for one of my requests to the server where I\'ll be storing the data:
data = urllib.urlencode({\'q\': \'Status\'})
u = urllib2.urlopen(\'http://myserver/inout-tracker\', data)
for line in u.readlines():
print line
Nothing special going on there. The problem I\'m having is that, based on how I read the docs, this should perform a Post Request because I\'ve provided the data parameter and that\'s not happening. I have this code in the index for that url:
if (!isset($_POST[\'q\'])) { die (\'No action specified\'); }
echo $_POST[\'q\'];
And every time I run my Python App I get the \'No action specified\' text printed to my console. I\'m going to try to implement it using the Request Objects as I\'ve seen a few demos that include those, but I\'m wondering if anyone can help me explain why I don\'t get a Post Request with this code. Thanks!
-- EDITED --
This code does work and Posts to my web page properly:
data = urllib.urlencode({\'q\': \'Status\'})
h = httplib.HTTPConnection(\'myserver:8080\')
headers = {\"Content-type\": \"application/x-www-form-urlencoded\",
\"Accept\": \"text/plain\"}
h.request(\'POST\', \'/inout-tracker/index.php\', data, headers)
r = h.getresponse()
print r.read()
I am still unsure why the urllib2 library doesn\'t Post when I provide the data parameter - to me the docs indicate that it should.
回答1:
u = urllib2.urlopen('http://myserver/inout-tracker', data)
h.request('POST', '/inout-tracker/index.php', data, headers)
Using the path /inout-tracker without a trailing / doesn't fetch index.php. Instead the server will issue a 302 redirect to the version with the trailing /.
Doing a 302 will typically cause clients to convert a POST to a GET request.
