python - write() argument must be str, not bytes

python -  write() argument must be str, not bytes

源代码

import requests
r = requests.get('https://www.baidu.com/img/bd_logo1.png')
if r.status_code == 200:
    with open('baidu.png','w') as f:
        f.write(r.content)        
else:
    print('获取失败')

修改后代码

import requests
r = requests.get('https://www.baidu.com/img/bd_logo1.png')
if r.status_code == 200:
    with open('baidu.png','wb') as f:
        f.write(r.content)        
else:
    print('获取失败')
 
# 原因分析 open的modle设置错误，需要将'w'改为'wb' ,'b'代表允许操作字节
