Question

我正在尝试基于此操作方法构建一个断开的链接检查器：https://dev.to/arvindmehairjan/build-a-web-crawler-to-check-for-broken-links-with-python-beautifulsoup-39mg

但是，我在代码行上遇到了问题，因为当我运行程序时，我收到此错误消息：File "/Users/Documents/brokenlinkchecker.py", line 26 print(f"Url: { link.get('href')} " + f"| 状态码：{response_code}") 语法错误：语法无效

我一直在思考可能导致此语法错误的原因。有没有人对我可以做些什么来使这个程序起作用有什么建议？

非常感谢！

代码如下：

# Import libraries
from bs4 import BeautifulSoup, SoupStrainer
import requests

# Prompt user to enter the URL
url = input("Enter your url: ")

# Make a request to get the URL
page = requests.get(url)

# Get the response code of given URL
response_code = str(page.status_code)

# Display the text of the URL in str
data = page.text

# Use BeautifulSoup to use the built-in methods
soup = BeautifulSoup(data)

# Iterate over all links on the given URL with the response code next to it
for link in soup.find_all('a'):
    print(f"Url: {link.get('href')} " + f"| Status Code: {response_code}")

您必须将附加参数 features="lxml" 或 features="html.parser" 传递给 BeautifulSoup 构造函数。

soup = BeautifulSoup(data,features="html.parser")

BeautifulSoup 断链检查器/网络爬虫
