Receive HTTP POST response by python
Question
I use the following example: http://www.w3schools.com/php/php_forms.asp
When I run it from browser, I see the results in the browser:
Welcome John
Your email address is john.doe@example.com
When I run python POST http request:
import httplib, urllib
params = urllib.urlencode({'@name': 'John','@email': 'John.doe@example.com'})
headers = {"Content-type": "application/x-www-form-urlencoded","Accept": "text/html"}
conn = httplib.HTTPConnection("10.0.0.201")
conn.request("POST","/welcome.php",params, headers)
response = conn.getresponse()
print "Status"
print response.status
print "Reason"
print response.reason
print "Read"
print response.read()
conn.close()
I see the following:
Status
200
Reason
OK

<html>
<body>
Welcome <br>
Your email address is:
</body>
</html>
The question is: How to receive POST request data in python?

You are using the wrong form names and the wrong HTTP method. There are no @ characters at their starts:
params = urllib.urlencode({'name': 'John','email': 'John.doe@example.com'})
Next, the form you point to uses GET , not POST as the handling method, so you'll have to add these parameters to the URL instead:
conn.request("GET", "/welcome.php?" + params, '', headers)
You are doing yourself a disservice by trying to drive the HTTPConnection() manually. You could use urllib2.urlopen() instead for example:
from urllib2 import urlopen
from urllib import urlencode
params = urlencode({'name': 'John','email': 'John.doe@example.com'})
response = urlopen('http://10.0.0.201/welcome.php?' + params)
print response.read()
or you could make use of the requests library (separate install) to make it yourself much easier still:
import requests
params = {'name': 'John','email': 'John.doe@example.com'}
response = requests.get('http://10.0.0.201/welcome.php', params=params)
print response.content

Instead of using urllib , use the requests library as Martijn suggested. It will make things much simpler.
Check out the documentation: http://docs.python-requests.org/en/latest/user/quickstart/

I just removed the "@" and it works:
Status
200
Reason
OK

Welcome John<br>
Your email address is: John.doe@example.com
</body>
</html>
Thank you Martijn Pieters.
As for POST method, i used the example for infrastructure testing purposes. Finally i need to fill mysql database and retrieve data from it over php using python script. What is the best method for it? Why is HTTPConnection() not recommended?
