使用 python 请求从网页中抓取数据

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）并且我在网络选项卡中找到了这个 api url https://api.leandomainsearch.com/search?query=computer&count=all（对于关键字：计算机），但出现此错误{'error': True, 'message': 'Invalid API Credentials'}这是代码import requestsr = 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RefererHTTP 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'])
