如何将JSON从网页导入Python脚本

Question

在我的一个脚本中获得了以下代码：

#
# url is defined above.
#
jsonurl = urlopen(url)

#
# While trying to debug, I put this in:
#
print jsonurl

#
# Was hoping text would contain the actual json crap from the URL, but seems not...
#
text = json.loads(jsonurl)
print text

我想做的是把我在Firefox中加载到脚本中时在URL上看到的{{.....etc.....}}内容，这样我就可以从中解析出一个值。我已经搜索了大量的内容，但是我还没有找到一个很好的答案，如何将以.json结尾的URL中的{{...}}内容真正转换成Python脚本中的对象。

Answer 1

从URL获取数据，然后调用json.loads

Python3示例：

import urllib.request, json 
with urllib.request.urlopen("http://maps.googleapis.com/maps/api/geocode/json?address=google") as url:
    data = json.loads(url.read().decode())
    print(data)

Python2示例：

import urllib, json
url = "http://maps.googleapis.com/maps/api/geocode/json?address=google"
response = urllib.urlopen(url)
data = json.loads(response.read())
print data

输出结果如下：

{
"results" : [
    {
    "address_components" : [
        {
            "long_name" : "Charleston and Huff",
            "short_name" : "Charleston and Huff",
            "types" : [ "establishment", "point_of_interest" ]
        },
        {
            "long_name" : "Mountain View",
            "short_name" : "Mountain View",
            "types" : [ "locality", "political" ]
        },
        {
...
