Hi, Jeremy,
Thank you so much for such a quick response!
Now my code runs well on GAE. I'd like to share some portion of it for
anyone else in need.
# make sure s is no more than 4,000 characters long before
urlencoded
def translate(self, s, lang):
params = {'q': s, 'v': '1.0', 'langpair': '|%s' % lang,
'format': 'html'}
# payload can be as long as 5,000 characters after urlencoded
response = urlfetch.fetch(url = _GOOGLE_TRANSLATE_BASE,
payload = urllib.urlencode(params),
method = urlfetch.POST,
headers = {'Content-Type': 'application/x-www-form-
urlencoded'})
data = simplejson.loads(response.content)
if data['responseStatus'] == 200:
return data['responseData']['translatedText']
else:
return '<h1>' + _ERROR_TITLE + '</h1><p class="e">' + str
(data['responseStatus']) + '</p>'
