成功解决:TypeError: Argument ‘parser‘ has incorrect type (expected lxml.etree._BaseParser, got type)
报错代码
我的代码:
import requests
import time
import random
from lxml import etree
headers = {
"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/95.0.4638.69 Safari/537.36"}
def baidu_search(search_keyword, max_page):
for page in range(max_page):
time.sleep(random.randint(1, 2))
url = 'https://www.baidu.com/s?wd=%s' % search_keyword + '&pn=' + str(page * 10)
r = requests.get(url, headers=headers)
html = r.text
print(html)
html_data = etree.HTML(html, etree.HTMLParser)
# r1 = html_data.xpath('//h3')
# r2 = html_data.xpath('//*[@class="c-abstract"]')
# r3 = html_data.xpath('//*[@class="t"]/a/@href')
#
# for i in range(8):
# r11 = r1[i].xpath('string(.)')
# r22 = r2[i].xpath('string(.)')
# r33 = r3[i]
# print(r11)
def main():
rows = [('吾皇万睡'), ('Nike')]
max_page = 1
for search_keyword in rows:
baidu_search(search_keyword, max_page)
if __name__ == '__main__':
main()
报错内容:
Traceback (most recent call last):
File "E:/Python/3.py", line 54, in <module>
main()
File "E:/Python/3.py", line 46, in main
baidu_search(search_keyword, max_page)
File "E:/Python/3.py", line 29, in baidu_search
html_data = etree.HTML(html,etree.HTMLParser)
TypeError: Argument 'parser' has incorrect type (expected lxml.etree._BaseParser, got type)
报错原因
报错内容翻译:TypeError:参数“parser”的类型不正确(应为lxml.etree。\u BaseParser,get type)
解决方法
把解析代码换成即可:
html_data = etree.HTML(html)
