sending POST data via urlfetch

[wachaca]

Hello,
I have a certain code working in PHP, which I am migrating to Python
in order to get it work under my App.

This is the original code in PHP which works, at the end I get a nice
long XML feed.

$post_data = array();

$post_data['accountType'] = "HOSTED_OR_GOOGLE";
$post_data['Email'] = "m...@email.com";
$post_data['Passwd'] = "mypass";
$post_data['service'] = "cp";
$post_data['source'] = "Beta-Api";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://www.google.com/accounts/
ClientLogin" );
curl_setopt($ch, CURLOPT_POST, 1 );
curl_setopt($ch, CURLOPT_HEADER, 1 );
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$postResult = curl_exec($ch);
print $postResult;
curl_close($ch);


In Python, this would translate to:
url = "https://www.google.com/accounts/ClientLogin"
payload = "accountType=HOSTED_OR_GOOGLE&service=cp&source=Beta-
Api&Email=my%40email.com&Passwd=mypass"
result = urlfetch.fetch(url,payload,2)

However, in the Python script, I always get
result.status_code = 403
Error=BadAuthentication

Am I making a mistake in thebuilding the payload parameter?

Thanks for your help

Hi,
It looks like you may be trying to fetch a Gdata feed with Google App
Engine. Our Gdata team has updated the Python client library to
include Google App Engine support, so you may consider using the
library, you can find information about the release here:

payload in python should be a urlencoded dict see

How did you figure out that payload was dictionary?
There is nothing about that in the manual at
http://code.google.com/appengine/docs/urlfetch/fetchfunction.html

Anyways, I tried the following code and it did not work.

url = "https://www.google.com/accounts/ClientLogin"

data = urlencode({'accountType':'HOSTED_OR_GOOGLE', 'service':'cp',
'source':'Tigabytes-Contacts-Api', 'Email':self.request.get("email"),
'Passwd':self.request.get("pass")})

result = urlfetch.fetch(url,payload=data,method=urlfetch.POST)

Guess I'll have to download the client library.
