使用Python脚本翻译URL时，请使用Google翻译。

我正在尝试从Python脚本使用Google翻译：

#!/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()

当我使用它时，我遇到了403错误。

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

然而，当通过浏览器访问相同的URL时却没有问题。有人能找出错误吗？还是说Google不允许这种用法？提前致谢。

如果 Google 不允许您这样做，您可以通过 Google 的 API 编程地翻译正常网站的源代码。我之前写了一个函数来实现这个功能：
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

你应该使用谷歌API。我找到并测试了这段代码，它可以正常工作：

#!/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

然而，这是要翻译文本，而不是网页（保留HTML标签）。是否可能翻译整个网页而不是仅限于文本？ - facha

你可以使用更好的Python代码来使用Google进行翻译：
