Question

我希望在给定视频的URL的情况下检索并使用python 3.2中的基本Vimeo数据。我是JSON（和python）的新手，但它看起来非常适合这样做。

请求Vimeo视频数据（通过API格式的.json网址）
将返回的JSON数据转换为python dict
显示字典键和＆amp;数据（“id”，“title”，“description”等）

另一个SO页面Get json data via url and use in python在python 2.x中做了类似的事情，但是语法更改（比如集成urllib2）让我尝试了这个。

>>> 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，因此我与使用python相关联。我对HTTP查询有足够的了解来猜测该响应对象中的数据，但对于python不足以理解为什么open失败以及如何正确引用它。我该怎么做而不是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'))

或使用请求：

import requests

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

>>> import urllib2
>>> import json
>>> req = urllib2.Request("http://vimeo.com/api/v2/video/31161781.json")
>>> response = urllib2.urlopen(req)
>>> content_string = response.read()
>>> content_string

>>> loaded_content = json.loads(content_string)
>>> type(content_string)
<type 'str'>
>>> type(loaded_content)
<type 'list'>

Answer 3

你可以试着像这样请求网址吗

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

如你所见，python有很多共享功能的库，你不需要构建一个开放器或任何东西来获取这些数据。

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)

如何在python 3.x中检索和显示Vimeo视频的JSON数据？
