HTTPError: HTTP Error 503: Service Unavailable goslate language detection request : Python

Question

I have just started using the goslate library in Python to detect the language of the words in a text but after testing it for 7-8 inputs, I gave the input which had the words written in two languages, Arabic and English. After which, it started giving me the error.

Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    execfile("C:/test_goslate.py");

    raise HTTPError(req.get_full_url(), code, msg, hdrs, fp)
HTTPError: HTTP Error 503: Service Unavailable

I wrote the code as :

# -*- coding: utf8 -*-
import urllib2
import goslate


gs = goslate.Goslate()

language_id = gs.detect('wait الدولة')

print (gs.get_languages()[language_id])

and now it is not working at all for any input which I tested previously and is giving me same error. I tried finding error resolve on google but nothing helped. This is what I found : Link 1 - StackOverflow

I tried updating it with the command as also suggested in the link above :

pip install -U goslate

but it did not help as it is already the newest updated version that I am using. Also I read in the library documentation that one gets this kind of error for translation when :

If you get HTTP 5xx error, it is probably because google has banned your client IP address from transation querying.

You could verify it by access google translation service in browser manually.

You could try the following to overcome this issue:

query through a HTTP/SOCK5 proxy, see Proxy Support
using another google domain for translation: gs = Goslate(service_urls=['http://translate.google.de'])
wait for 3 seconds before issue another querying

I tried using proxy connection but nothing helped.

EDIT Could the reason be that Google allows only some number of requests per day ? In that case what better can be done ? Is there any other Python based library which can help me resolve this?

Answer 1

maybe looking for this: https://pypi.python.org/pypi/textblob it is better than goslate,

since textblob is blocked as of now, maybe py-translate could do the trick,

https://pypi.python.org/pypi/py-translate/#downloads

http://pythonhosted.org/py-translate/devs/api.html

from translate import translator
translator('en', 'es', 'Hello World!')

"py-translate is a CLI Tool for Google Translate written in Python!"

the first argument to the translator function is the source language, the second is the target language, and the third is the phrase to be translated,

it returns a dictionary, which the documentation refers to as a request interface
