本文探讨了在使用Python的BeautifulSoup和requests库时遇到的一个常见错误：TypeError: object of type 'Response' has no len()。作者尝试了将html作为参数传递给BeautifulSoup，但仍然无法解决问题。文中提供了具体的代码示例，包括请求URL、设置headers以及尝试解析HTML的代码。

Issue: when I try to execute the script, BeautifulSoup(html, ...) gives the error message "TypeError: object of type 'Response' has no len(). I tried passing the actual html as a parameter, but it still doesn't work.

url = "https://www.ximalaya.com/shangye/6855034/"
    headers={
        'User-Agent':'Mozilla/5.0 (Windows NT 10.0; WOW64; rv:62.0) Gecko/20100101 Firefox/62.0',
    }
    html=requests.get(url,headers=headers)
    html.encoding = 'utf-8'
    # print(html.text)

    soup = BeautifulSoup(html.text, 'html.parser')
    # soup = BeautifulSoup(html, 'html.parser'),传入参数html不行哦
    print(soup.text)

在B站学习python爬虫期间，根据老师写的代码，我放在pycharm编辑器中一直运行不出来，具体源代码是这样的：`import code import xlwt import bs4 import re import urllib.request import sqlite3 def main(): baseurl = “http://movie.douban.com/top250?star=” # 爬取网页 datalist = getData (baseurl) savepath = “豆瓣电影To

TypeError object of type ‘type’ has no len()—Python报错问题：

翻译过来是类型为“type”的TypeError对象没有len（），我报错的代码是： #coding=utf-8 print(请输入一个字符串：) a = input('') #回文的长度至少为2 if len(str) < 2: print('请不要输入空字符串！') a = input('请重新输入一个字符串：') b = reversed(list(a)) if list(b) == list(a): print(a,'是回文') else: print(a,'不是回文') 运行结果：将if len(a) < 2 里面的a错写成了python里面

译为： 'Response' 类型的对象没有 len（）将响应的res 改为res.text即可。在使用bs4 的时候爆出了这样一个错。

TypeError: object of type 'Response' has no len() 这是为何？

代码如下： rom bs4 import BeautifulSoup import requests url='XXX' web=requests.get(url) soup=BeautifulSoup(web,'lxml') print(soup) 就这几行，出错是： E:\Python\Python35-32\python.exe C:/Users/ty/PycharmProjects/...

这个错误的原因可能是因为您使用的是 Response 对象而不是 HTML 文本。请检查您的代码，确保您已经正确地将请求发送到目标网站并从中获取到了 HTML 文本。您可以尝试使用 response.text 或 response.content 来获取 ...

这个错误提示是因为 `BeautifulSoup` 期望接收一个字符串类型的参数，而 `page_text` 是一个 `Response` 类型的对象。你需要将 `page_text.content` 传递给 `BeautifulSoup`，而不是 `page_text`。修改代码如下： `...

嗯，用户遇到了一个TypeError，具体是“object of type 'NoneType' has no len()”。看起来这个问题出现在他们使用BeautifulSoup解析HTML的时候。首先，我需要回想一下这个错误的常见原因。根据之前的对话，当代码中...
