以下代码实现一模一样的功能，对比两者的代码量：
|
||
|
||
## 获取元素内容
|
||
|
||
```python
|
||
url = 'https://baike.baidu.com/item/python'
|
||
|
||
# 使用 requests：
|
||
from lxml import etree
|
||
headers = {'User-Agent':'Mozilla/5.0 (Windows NT 6.3; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2272.118 Safari/537.36'}
|
||
response = requests.get(url, headers = headers)
|
||
html = etree.HTML(response.text)
|
||
element = html.xpath('//h1')[0]
|
||
title = element.text
|
||
|
||
# 使用 DrissionPage：
|
||
page = MixPage('s')
|
||
page.get(url)
|
||
title = page('tag:h1').text
|
||
```
|
||
|
||
?> **Tips:** <br>DrissionPage 自带默认 headers
|
||
|
||
## 下载文件
|
||
|
||
```python
|
||
url = 'https://www.baidu.com/img/flexible/logo/pc/result.png'
|
||
save_path = r'C:\download'
|
||
|
||
# 使用 requests：
|
||
r = requests.get(url)
|
||
with open(f'{save_path}\\img.png', 'wb') as fd:
|
||
for chunk in r.iter_content():
|
||
fd.write(chunk)
|
||
|
||
# 使用 DrissionPage：
|
||
page.download(url, save_path, 'img') # 支持重命名，处理文件名冲突
|
||
```
