我怎样才能将这个符号视为文本?
How can I treat this ampersand as text?
from googlefinance import getQuotes
print(getQuotes("NSE:M\&MFIN"),)
& 符号被视为代码,但我想将其视为文本;我收到一个错误的请求异常:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/.../site-packages/googlefinance/__init__.py", line 70, in getQuotes
content = json.loads(request(symbols))
File "/.../site-packages/googlefinance/__init__.py", line 33, in request
resp = urlopen(req)
File "/.../urllib/request.py", line 223, in urlopen
return opener.open(url, data, timeout)
File "/.../urllib/request.py", line 532, in open
response = meth(req, response)
File "/.../urllib/request.py", line 642, in http_response
'http', request, response, code, msg, hdrs)
File "/.../urllib/request.py", line 570, in error
return self._call_chain(*args)
File "/.../urllib/request.py", line 504, in _call_chain
result = func(*args)
File "/.../urllib/request.py", line 650, in http_error_default
raise HTTPError(req.full_url, code, msg, hdrs, fp)
urllib.error.HTTPError: HTTP Error 400: Bad Request
我试图逃避它(使用 \
)但这也没有用。
如何将这个 & 符号视为文本?
该库相当幼稚,因为它只是将符号附加到 URL 而没有正确编码,请参阅 the source code:
def buildUrl(symbols):
symbol_list = ','.join([symbol for symbol in symbols])
# a deprecated but still active & correct api
return 'http://finance.google.com/finance/info?client=ig&q=' \
+ symbol_list
您可以使用 urllib.parse.quote()
function:
手动预先引用来解决此问题
from urllib.parse import quote
print(getQuotes(quote("NSE:M&MFIN")))
演示:
>>> from googlefinance import getQuotes
>>> from urllib.parse import quote
>>> print(getQuotes(quote("NSE:M&MFIN")))
