使用Python解析豆瓣上Json格式数据

现在的API接口多为xml或json,json解析更简洁相对xml来说

 

以豆瓣的API接口为例，解析返回的json数据：

https://api.douban.com/v2/book/1220562

{
    "id":"1220562",
    "alt":"http://book.douban.com/book/1220562",
    "rating":{"max":10, "average":"7.0", "numRaters":282, "min":0},
    "author":[{"name":"片山恭一"}, {"name":"豫人"}],
    "alt_title":"",
    "image":"http://img1.douban.com/spic/s1747553.jpg",
    "title":"满月之夜白鲸现",
    "mobile_link":"http://m.douban.com/book/subject/1220562/",
    "summary":"那一年，是听莫扎特、钓鲈鱼和家庭破裂的一年。说到家庭破裂，母亲怪自己当初没有找到好男人，父亲则认为当时是被狐狸精迷住了眼，失常的是母亲，但出问题的是父亲……。",
    "attrs":{ 
       "publisher":["青岛出版社"],
        "pubdate":["2005-01-01"],
        "author":["片山恭一", "豫人"],
        "price":["18.00元"],
        "title":["满月之夜白鲸现"],
        "binding":["平装(无盘)"],
        "translator":["豫人"],
        "pages":["180"]
    },
    "tags":[
        {"count":106, "name":"片山恭一"},
        {"count":50, "name":"日本"},
        {"count":42, "name":"日本文学"},
        {"count":30, "name":"满月之夜白鲸现"},
        {"count":28, "name":"小说"},
        {"count":10, "name":"爱情"},
        {"count":7, "name":"純愛"},
        {"count":6, "name":"外国文学"}
    ]
}

用python解析我们想要的数据如：id、rating里的max 、tags第一行的name值

import urllib2
import json
html = urllib2.urlopen(r'https://api.douban.com/v2/book/1220562')
hjson = json.loads(html.read())
print hjson['id']
print hjson['rating']['max']
print hjson['tags'][0]['name']

结果图：
