python 爬虫提示如下

GuessedAtParserWarning: No parser was explicitly specified, so I'm using the best available HTML parser for this system ("html.parser"). This usually isn't a problem, but if you run this code on another system, or in a different virtual environment, it may use a different parser and behave differently.

The code that caused this warning is on line 10 of the file C:\Users\PycharmProjects\pythonProject\pa\main.py. To get rid of this warning, pass the additional argument 'features="html.parser"' to the BeautifulSoup constructor.

  bs_obj = BeautifulSoup(req_html)

大致意思是:GuessedAtParserWarning：未明确指定解析器，因此我正在为此系统使用最佳的HTML解析器（“ html.parser”）

我大代码是这样的

import requestsfrom bs4 import BeautifulSoupdef getContent():    url = "https://read.qidian.com/chapter/tlBx1lEZoo3djrstIrF5-w2/-hwjPfM_yFT6ItTi_ILQ7A2"    req_url = requests.get(url)    req_html = req_url.text    bs_obj = BeautifulSoup(req_html)    texts = bs_obj.find_all("div", class_="read-content j_readContent")    print(texts)if __name__ == "__main__":    getContent()

处理方法就是添加html.parser

效果如下

import requestsfrom bs4 import BeautifulSoupdef getContent():    url = "https://read.qidian.com/chapter/tlBx1lEZoo3djrstIrF5-w2/-hwjPfM_yFT6ItTi_ILQ7A2"    req_url = requests.get(url)    req_html = req_url.text    bs_obj = BeautifulSoup(req_html, "html.parser")    texts = bs_obj.find_all("div", class_="read-content j_readContent")    print(texts)if __name__ == "__main__":    getContent()

运行ok
