先到天行数据官网（https://www.tianapi.com/）注册一个账号，获取APIKEY。
拉到下面点击美女图片：
找到我们需要用到的接口地址（http://api.tianapi.com/world/）：
我们还需要在接口地址后面加上对应的参数APIKEY.即（http://api.tianapi.com/world/?&key=APIKEY）
用浏览器打开地址，会出现一串json格式的数据，不过是还没格式化的

}现在看起来就顺眼多了。
观察这串数据，我们要获取的是newslist里面的title，picUrl和url.
可以先获取newslist的json对象，然后循环遍历它得到我们需要的数据，最后再保存到mysql数据库中。
以下是完整的代码：
import requests
import mysql.connector as mysql
cnx=mysql.connect(user='root',password='123456',database='meinv')
#获得游标
cursor=cnx.cursor()
rs=requests.get("http://api.tianapi.com/world/?key=68c42f9baf78d084cfc3cc29f8c4e569")
jsonobj=rs.json()['newslist']
#遍历这个列表
for i in jsonobj:
print(i['title'],i['picUrl'],i['url'])
#持久化保存 mysql
str1="insert into picture values('{}','{}','{}')".format(i['title'],i['picUrl'],i['url'])
cursor.execute(str1)
cnx.commit()
其中，数据库的建表语句是：
CREATE TABLE `picture` (
`title` varchar(255) DEFAULT NULL,
`picUrl` varchar(255) DEFAULT NULL,
`url` varchar(255) DEFAULT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8
注意各个字段要一一对应。
运行代码，控制台打印：

大功告成！
