Python:将JSON(由URL返回)转换为列表 [英] Python: Convert JSON (returned by URL) into List

问题描述

我正在请求将youtube搜索字词与jquery自动完成功能配合使用，但是很难将URL响应转换为正确的格式.

I am requesting youtube search terms for use with jquery autocomplete, but am having a hard time converting the URL response into a proper format.

在我的(Django/Python)视图中，我这样做:

In my (Django/Python) view I do:

data2 = urllib2.urlopen('http://suggestqueries.google.com/complete/search?hl=en&ds=yt&client=youtube&hjson=t&jsonp=window.yt.www.suggest.handleResponse&q=jum&cp=3')

(为简单起见，我将搜索字词="jump"硬编码)

(I hardcoded the search term = 'jump' for simplicity)

如果我执行data2.read()，我得到的是我认为的JSON(将URL复制粘贴到浏览器中也会返回此值.)

If I do data2.read() I get what I believe is JSON (copy-pasting the url into a browser also returns this.)

window.yt.www.suggest.handleResponse(["jum",[["jumpstyle","","0"],["jump","","1"],["jump around","","2"],["jump on it","","3"],["jumper","","4"],["jump around house of pain","","5"],["jumper third eye blind","","6"],["jumbafund","","7"],["jump then fall taylor swift","","8"],["jumpstyle music","","9"]],"","","","","",{}])

我需要以jquery自动完成功能可以读取的格式返回此内容.我知道如果可以将其放入列表中，例如mylist = ['jumpstyle', 'jump', 'jump around', ...]

I need to return this in a format that jquery autocomplete can read. I know it will work if I can get it into a list, for example, mylist = ['jumpstyle', 'jump', 'jump around', ...]

，然后在将其返回之前将其转换回json:

and then convert it back into json before returning it:

json.dumps(mylist)

(如果我直接按照上面的定义直接定义mylist，这将起作用.)

(This works if I directly define mylist directly as written above.)

但是我无法从URL返回的数据获取一个简单列表(然后将其转换回JSON)或某种可以直接返回以供自动完成功能使用的JSON形式.

But I cannot get from the data that is returned by the URL to either a simple list (which I then convert back into JSON) or to some form of JSON that I can return directly to be used by auto complete.

除其他外，我尝试过

j2 = json.loads(data2)

和

j2 = json.loads(data2.read())

希望有人可以提供帮助！

Hope someone can help!

推荐答案

删除&jsonp=window.yt.www.suggest.handleResponse部分

import json
import urllib2

data = urllib2.urlopen('http://suggestqueries.google.com/complete/search?hl=en&ds=yt&client=youtube&hjson=t&q=jum&cp=3')

j = json.load(data)
k = [i for i, j, k in j[1]]
l = json.dumps(k)
