Question

我尝试使用StackExchange API，然后找到了Python的Py-StackExchange库。我在Windows中通过easy_install安装了它。

以下是代码：

from stackexchange import Site, StackOverflow

so = Site(StackOverflow)
my_favourite_guy = so.user(2309097)
print my_favourite_guy.reputation.format()
print len(my_favourite_guy.answers), 'answers'

这是错误：

Traceback (most recent call last):
  File "C:\Users\Tasos\Desktop\test - Copy.py", line 8, in <module>
    my_favourite_guy = so.user(2309097)
  File "build\bdist.win-amd64\egg\stackexchange\__init__.py", line 626, in user
    u, = self.users((nid,), **kw)
  File "build\bdist.win-amd64\egg\stackexchange\__init__.py", line 631, in users
    return self._get(User, ids, 'users', kw)
  File "build\bdist.win-amd64\egg\stackexchange\__init__.py", line 621, in _get
    return self.build(root, typ, coll, kw)
  File "build\bdist.win-amd64\egg\stackexchange\__init__.py", line 598, in build
    json = self._request(url, kw)
  File "build\bdist.win-amd64\egg\stackexchange\__init__.py", line 570, in _request
    json, info = request_mgr.json_request(url, new_params)
  File "build\bdist.win-amd64\egg\stackexchange\web.py", line 120, in json_request
    return (json.loads(req.data), req.info)
  File "C:\Python27\lib\json\__init__.py", line 338, in loads
    return _default_decoder.decode(s)
  File "C:\Python27\lib\json\decoder.py", line 365, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "C:\Python27\lib\json\decoder.py", line 383, in raw_decode
    raise ValueError("No JSON object could be decoded")
ValueError: No JSON object could be decoded

我在Wiki中看到了以下内容，但我没有使用任何代理，代码版本是easy_install的最新版本：

这可能是某些代理/路由器与请求重合的结果头。可能是您的路由器/代理添加了请求的标头 gzip数据，但不解压缩，而且你正在运行稍微旧版本的代码，不处理gzip 压缩。在这种情况下，只需更新到最新版本库。

Answer 1

version on PyPI已过时（2011年发布），仍然使用API版本1.1，该版本已为shut down。

Github codebase已更新为使用API v2.2，直接安装：

pip install git+https://github.com/lucjon/Py-StackExchange

或使用easy_install，下载当前的主zip：

easy_install https://github.com/lucjon/Py-StackExchange/archive/640eac1525baaf57474ddbc3be2b580f00e4f1e8.zip

要获得列出的答案，您需要致电.fetch()：

print len(my_favourite_guy.answers.fetch()), 'answers'

这只会获取答案的第一页：

>>> from stackexchange import Site, StackOverflow
>>> so = Site(StackOverflow)
>>> my_favourite_guy = so.user(2309097)
>>> print my_favourite_guy.reputation.format()
563
>>> print len(my_favourite_guy.answers.fetch()), 'answers'
19 answers
>>> my_favourite_guy = so.user(100297)
>>> print my_favourite_guy.reputation.format()
251.2k
>>> print len(my_favourite_guy.answers.fetch()), 'answers'
30 answers

我上次检查时有30多个答案。使用.extend_next()调用来获取下一个查询集，直到用完为止。
