目录
一、目标1:爬取指定json中数据
二、目标2:循环取json中数据
三、目标3:提取每个数据中的某一项
四、网络安全小圈子
爬取data里数据
核心代码:
dirt1 = json.loads(res.text) print(dirt1['data'])
(1)json.loads()方法可用于解析有效的JSON字符串并将其转换为Python字典
(2)dirt1['data']是打印json中的data部分
运行结果:
完成了爬取
代码:
import requests import json from fake_useragent import UserAgent def get_json(): try: url = 'https://napi-huawei.tianyancha.com/next/web/home/vajialist?_=1688703382196' ua = UserAgent() headers = { 'User-Agent': ua.chrome, } res = requests.get(url, headers=headers,timeout=10) dirt1 = json.loads(res.text) print(dirt1['data']) except: return "" if __name__ == '__main__': get_json()
我这里有2部分才到列表里面是把
所以我要取列表中数据就要变为
dirt1['data']['detailList']
循环:
使用一个循环就可以区分开来了
for item in dirt1['data']['detailList']: print(item)
代码:
import requests import json from fake_useragent import UserAgent def get_json(): try: url = 'https://napi-huawei.tianyancha.com/next/web/home/vajialist?_=1688703382196' ua = UserAgent() headers = { 'User-Agent': ua.chrome, } res = requests.get(url, headers=headers,timeout=10) dirt1 = json.loads(res.text) #print(dirt1['data']) for item in dirt1['data']['detailList']: print(item) except: return "" if __name__ == '__main__': get_json()
目标
提取这2个指定项
理解:
此时item其实相当于dirt1['data']['detailList']中的一项
所以
item['resourceKey'] === ['data']['detailList']['resourceKey']
这行代码精确到数据中的更小一项resourceKey
运行结果:
完整代码:
import requests import json from fake_useragent import UserAgent def get_json(): try: url = 'https://napi-huawei.tianyancha.com/next/web/home/vajialist?_=1688703382196' ua = UserAgent() headers = { 'User-Agent': ua.chrome, } res = requests.get(url, headers=headers,timeout=10) dirt1 = json.loads(res.text) #print(dirt1['data']) for item in dirt1['data']['detailList']: #print(item) print(item['resourceKey']) print(item['resourceName']) except: return "" if __name__ == '__main__': get_json()
