如何在 python 3.x 中检索和显示 Vimeo 视频的 JSON 数据？

Question

我想在给定视频 URL 的情况下在 python 3.2 中检索和使用基本 Vimeo 数据。我是 JSON（和 python）的新手，但它看起来很适合这样做。

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. 显示字典键和字符串数据（“id”，“标题”，“描述”等）

另一个SO页面通过 url 获取 json 数据并在 python 中使用 在 python 2.x 中做了类似的事情，但是语法的变化（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'

该代码将集成到现有项目中，因此我必须使用 python。我对 HTTP 查询有足够的了解，可以猜测该响应对象中的数据，但对 python 的了解还不够，无法理解打开失败的原因以及如何正确引用它。我应该尝试什么来代替 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'))

或者有请求：

import requests

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

Answer 2

你可以尝试像这样请求url吗？

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

正如你所看到的，Python有很多共享功能的库，你不需要构建一个开启器或任何东西来获取这些数据。

查看：http://www.voidspace.org.uk/python/articles/ urllib2.shtml

>>> 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 4

你可以尝试这样：

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