python - Json 显然被运行 Python 代码破坏了

问题描述

我正在使用Googletrans用于 python 的 API，谷歌使用可选的目标和源语言规范翻译任何给定的输入字符串。

我的问题：在使用它作为代码的一部分逐行处理多行对话转录后，我似乎破坏了与 Json 相关的内容，现在 API 拒绝运行。

一段示例代码，之前运行完美，但现在抛出以下错误：

from googletrans import Translator
translator = Translator()
translator.translate('안녕하세요.')

---------------------------------------------------------------------------
JSONDecodeError                           Traceback (most recent call last)
<ipython-input-1-2a9f8e95ca66> in <module>
      1 from googletrans import Translator
      2 translator = Translator()
----> 3 translator.translate('안녕하세요.')

/usr/local/anaconda3/lib/python3.7/site-packages/googletrans/client.py in translate(self, text, dest, src)
    170 
    171         origin = text
--> 172         data = self._translate(text, dest, src)
    173 
    174         # this code will be updated when the format is changed.

     79         r = self.session.get(url, params=params)
     80 
---> 81         data = utils.format_json(r.text)
     82         return data
     83 

/usr/local/anaconda3/lib/python3.7/site-packages/googletrans/utils.py in format_json(original)
     60         converted = json.loads(original)
     61     except ValueError:
---> 62         converted = legacy_format_json(original)
     63 
     64     return converted

     52             text = text[:p] + states[j][1] + text[nxt:]
     53

    347             parse_constant is None and object_pairs_hook is None and not kw):
--> 348         return _default_decoder.decode(s)
    349     if cls is None:
    350         cls = JSONDecoder

/usr/local/anaconda3/lib/python3.7/json/decoder.py in decode(self, s, _w)
    335 
    336         """
--> 337         obj, end = self.raw_decode(s, idx=_w(s, 0).end())
    338         end = _w(s, end).end()
    339         if end != len(s):

/usr/local/anaconda3/lib/python3.7/json/decoder.py in raw_decode(self, s, idx)
    353             obj, end = self.scan_once(s, idx)
    354         except StopIteration as err:
--> 355             raise JSONDecodeError("Expecting value", s, err.value) from None
    356         return obj, end

JSONDecodeError: Expecting value: line 1 column 1 (char 0)

可能发生了什么以及可以采取什么措施来解决它？

解决方案

I read the PyPI documentation of googletrans 2.4.0

It mentions the following

The maximum character limit on a single text is 15k.

Due to limitations of the web version of google translate, this API does not guarantee that the library would work properly at all times (so please use this library if you don’t care about stability).

Probably the text you are translating is too long. Thus, throwing the error.
