如何使用python从在线pdf文件中获取数据？

import requests
import PyPDF2

# 下载PDF文件
url = "https://example.com/path/to/file.pdf"
response = requests.get(url)
with open("file.pdf", "wb") as file:
    file.write(response.content)

# 解析PDF文件
with open("file.pdf", "rb") as file:
    pdf = PyPDF2.PdfFileReader(file)
    num_pages = pdf.getNumPages()
    
    # 遍历每一页
    for page_num in range(num_pages):
        page = pdf.getPage(page_num)
        text = page.extractText()
        
        # 处理提取的文本数据
        # ...

        print(text)
