translate url with google translate from python script

I'm trying to use google translate from a python script:

#!/usr/bin/env python
from urllib2 import urlopen
from urllib import urlencode

base_url = "http://www.google.com/translate?"
params = (('langpair','en|es'), ('u','http://asdf.com'),)
url = base_url+urlencode(params)
print "Encoded URL: %s" % url 
print urlopen(url).read()

I'm getting the error 403 when I use it.

# ./1.py 
Encoded URL: http://www.google.com/translate?langpair=en%7Ces&u=http%3A%2F%2Fasdf.com
Traceback (most recent call last):
开发者_如何转开发...
urllib2.HTTPError: HTTP Error 403: Forbidden

However the same URL works fine when accessed from browser. Could anyone spot the error? Or is it that google does not allow this type of usage?

Thanks in advance

If Google doesn't let you do this, you could programatically translate the normal website's source via the Google's APIs.

I wrote a function for this a little while back:

def translate(text, src = '', to = 'en'):
  parameters = ({'langpair': '{0}|{1}'.format(src, to), 'v': '1.0' })
  translated = ''

  for text in (text[index:index + 4500] for index in range(0, len(text), 4500)):
    parameters['q'] = text
    response = json.loads(urllib.request.urlopen('http://ajax.googleapis.com/ajax/services/language/translate', data = urllib.parse.urlencode(parameters).encode('utf-8')).read().decode('utf-8'))

    try:
      translated += response['responseData']['translatedText']
    except:
      pass

  return translated

You should be using the google API. I found and tested this code, it works:

#!/usr/bin/env python
from urllib2 import urlopen
from urllib import urlencode
import sys


lang1=sys.argv[1]
lang2=sys.argv[2]
langpair='%s|%s'%(lang1,lang2)
text=' '.join(sys.argv[3:])
base_url='http://ajax.googleapis.com/ajax/services/language/translate?'
params=urlencode( (('v',1.0),
                   ('q',text),
                   ('langpair',langpair),) )
url=base_url+params
content=urlopen(url).read()
start_idx=content.find('"translatedText":"')+18
translation=content[start_idx:]
end_idx=translation.find('"}, "')
translation=translation[:end_idx]
print translation

You want to use the offical Google Translate APIs:

http://code.google.com/intl/de-DE/apis/language/translate/overview.html

Apart from that:

http://www.catonmat.net/blog/python-library-for-google-search/

your problem is because you have no headers

(which tells google what is your browser and compatibility)

I had this error before when I made my google translate api

you can find it here: https://github.com/mouuff/Google-Translate-API

you can use a much better python code for translating with google:
