以下是一个利用Python进行逆向分析获取数据的代码,实现目标为获取“新书推荐”图书名称、图书ID、图书照片网址并存储数据。
首先,我们需要导入需要的Python第三方库:
```python
import requests
from bs4 import BeautifulSoup
```
接下来,我们需要向目标网站发送请求,获取HTML源代码:
```python
url = 'https://www.example.com/new_books'
response = requests.get(url)
html = response.text
```
然后,我们需要使用BeautifulSoup库解析HTML源代码,获取我们需要的数据:
```python
soup = BeautifulSoup(html, 'html.parser')
books = soup.find_all(class_='new_book')
book_names = []
book_ids = []
book_photos = []
for book in books:
book_name = book.find(class_='book_name').text.strip()
book_id = book.find(class_='book_id').text.strip()
book_photo = book.find('img')['src']
book_names.append(book_name)
book_ids.append(book_id)
book_photos.append(book_photo)
```
最后,我们可以将数据存储到文件中,例如CSV文件:
```python
import csv
with open('new_books.csv', 'w', newline='', encoding='utf-8') as file:
writer = csv.writer(file)
writer.writerow(['Book Name', 'Book ID', 'Book Photo'])
for i in range(len(book_names)):
writer.writerow([book_names[i], book_ids[i], book_photos[i]])
```
完整代码如下:
```python
import requests
from bs4 import BeautifulSoup
import csv
url = 'https://www.example.com/new_books'
response = requests.get(url)
html = response.text
soup = BeautifulSoup(html, 'html.parser')
books = soup.find_all(class_='new_book')
book_names = []
book_ids = []
book_photos = []
for book in books:
book_name = book.find(class_='book_name').text.strip()
book_id = book.find(class_='book_id').text.strip()
book_photo = book.find('img')['src']
book_names.append(book_name)
book_ids.append(book_id)
book_photos.append(book_photo)
with open('new_books.csv', 'w', newline='', encoding='utf-8') as file:
writer = csv.writer(file)
writer.writerow(['Book Name', 'Book ID', 'Book Photo'])
for i in range(len(book_names)):
writer.writerow([book_names[i], book_ids[i], book_photos[i]])
```
在运行完这段代码后,我们就能得到一个名为new_books.csv的文件,其中包含了我们所需要的数据。
