python 2.7中googlefinance的HTTP错误404

google-finance json python

Polta Lashka · 技术社区 · 7 年前

在python 2.7 shell中,我运行了以下内容:

$from googlefinance import getQuotes
$import json
$from urllib2 import urlopen
$print json.dumps(getQuotes('AAPL'), indent=2)

在第4个命令上收到错误消息,如下所示:

Traceback (most recent call last):
  Python Shell, prompt 3, line 1
  File "C:\Users\mlashkar\_development\python\v2.7\Lib\site-packages\googlefinance\__init__.py", line 70, in getQuotes

谷歌金融似乎修改了他们的URL/端点和 googlefinance 包尚未更新以反映更改。

https://finance.google.com/finance?output=json&q=TICKER_SYMBOL

回应

Google Finance以这种格式返回JSON结果

\n// [\n{\n"symbol" : "AAPL",\n"exchange" : "NASDAQ",\n"id": "22144",\n"t" 
: "AAPL",\n"e" : "NASDAQ",\n"name" : "Apple Inc."\n, "f_reuters_url" : 
"http:\\x2F\\x2Fstocks.us.reuters.com\\x2Fstocks\\x2Fratios.asp?rpc=66\\x26symbol=AAPL.O",\n"f_recent_quarter_date" : "Q3 (Jul \\x2717)",\n"f_annual_date" : "2016",\n"f_ttm_date" : "2015",\n"financials" :

    ... a lot more stuff ...
[\n]\n}]\n'

Python的JSON解析器无法按原样加载它,因为它有前导 // ,并将一切包裹在里面 []

完成代码和解析

requests 模块,但如果您想要一个内置 urllib

import json

import requests

rsp = requests.get('https://finance.google.com/finance?q=AAPL&output=json')

if rsp.status_code in (200,):

    # This magic here is to cut out various leading characters from the JSON 
    # response, as well as trailing stuff (a terminating ']\n' sequence), and then
    # we decode the escape sequences in the response
    # This then allows you to load the resulting string
    # with the JSON module.
    fin_data = json.loads(rsp.content[6:-2].decode('unicode_escape'))

    # print out some quote data
    print('Opening Price: {}'.format(fin_data['op']))
    print('Price/Earnings Ratio: {}'.format(fin_data['pe']))
    print('52-week high: {}'.format(fin_data['hi52']))
    print('52-week low: {}'.format(fin_data['lo52']))

这将输出:

Opening Price: 162.71
Price/Earnings Ratio: 18.43
52-week high: 164.94
52-week low: 102.53

一个完整的代码JSON中包含的数据比我输出的要多得多,所以您可以决定如何使用其中的任何一个。

选择

或者,您可以使用 yahoo-finance 由于雅虎仍然提供一个真正的财务API,该模块可能不太可能出现这样的问题。
