如何在python 3.x中检索和显示Vimeo视频的JSON数据？

Question

给定视频的URL，我想在python 3.2中检索并使用基本的Vimeo数据。我是JSON（和python）的新手，但看起来很适合执行此操作。

1. 请求Vimeo视频数据（通过API格式的.json URL）
2. 将返回的JSON数据转换为python字典
3. 显示字典键和数据（“ id”，“ title”，“ description”等）

另一个SO页Get json data via url and use in python在python 2.x中做了类似的操作，但是语法更改（例如集成urllib2）使我尝试了此操作。

>>> import urllib
>>> import json
>>> req = urllib.request.urlopen("http://vimeo.com/api/v2/video/31161781.json")
>>> opener = urllib.request.build_opener()
>>> f = opener.open(req)
Traceback (most recent call last):
  File "<pyshell#28>", line 1, in <module>
    f = opener.open(req)
  File "C:\Python32\lib\urllib\request.py", line 358, in open
    protocol = req.type
AttributeError: 'HTTPResponse' object has no attribute 'type'

此代码将集成到现有项目中，因此我只能使用python。我对HTTP查询有足够的了解，无法猜测该响应对象中的数据，但对于python却了解的不够，因此无法理解为什么打开失败以及如何正确引用它。我应该怎么做才能代替opener.open(req)？

Answer 1

这对我有用：

import urllib.request, json

response = urllib.request.urlopen('http://vimeo.com/api/v2/video/31161781.json')
content = response.read()
data = json.loads(content.decode('utf8'))

或带有请求：

import requests

data = requests.get('http://vimeo.com/api/v2/video/31161781.json').json()

Answer 2

您可以尝试仅这样请求网址

response = urllib.urlopen('http://www.weather.com/weather/today/Ellicott+City+MD+21042')
response_dict = json.loads(response.read())

如您所见，Python有许多共享功能的库，您无需构建打开器或任何东西来获取此数据。

您可以尝试这样：

import requests
url1 = 'http://vimeo.com/api/v2/video/31161781.json'
html = requests.get(url1)
html.encoding = html.apparent_encoding
print(html.text)
