使用 python 请求从 web 页面抓取数据

Question

我正在尝试抓取域搜索页面（您可以在其中输入关键字并获得一些随机结果），我在网络选项卡https中找到了这个 api url关键字：计算机），但我收到此错误

{'error': True, 'message': 'Invalid API Credentials'}

这是代码

import requests

r = requests.get("https://api.leandomainsearch.com/search?query=cmputer&count=all")
print(r.json())

Answer 1

该站点需要您设置Authorization和Referer HTTP 标头。

例如：

import re
import json
import requests


kw = 'computer'

url = 'https://leandomainsearch.com/search/'
api_url = 'https://api.leandomainsearch.com/search'

api_key = re.search(r'"apiKey":"(.*?)"', requests.get(url, params={'q': kw}).text)[1]
headers = {'Authorization': 'Key ' + api_key, 'Referer': 'https://leandomainsearch.com/search/?q={}'.format(kw)}
data = requests.get(api_url, params={'query': kw, 'count': 'all'}, headers=headers).json()

# uncomment this to print all data:
# print(json.dumps(data, indent=4))

for d in data['domains']:
    print(d['name'])

print()
print('Total:', data['_meta']['total_records'])
