Py-StackExchange引發一個值錯誤

Question

我嘗試使用StackExchange API，並找到Python的Py-StackExchange庫。我通過Windows中的easy_install安裝它。

下面是代碼：

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' 

這裏是錯誤：

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Wiki下面看到的，但我不使用任何代理和代碼版本是最新的通過easy_install：

This is probably the result of some proxy/router mangling with request headers. It could be that your router/proxy adds headers requesting gzip data, but doesn't decompress it, and that you are running a slightly old version of the code which does not deal with gzip compression. In this case, just update to the latest version of the library.

Answer 1

version on PyPI很好過時（2011年發佈），仍然使用API​​版本1.1，版本號爲shut down。

的Github codebase已更新爲使用API​​ v2.2中，安裝直接：

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

或使用easy_install，下載最新的主拉鍊：

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

爲了得到答案，列出你需要致電.fetch()：

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

這僅獲取了第一頁答案：

>>> 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 

我有幾個30分多的答案，我最後一次檢查。使用.extend_next()調用來獲取下一個查詢集，直到用完爲止。
