python - base64转图片
折腾了base64转png弄了很久，使用以下代码进行转换后图片一直打不开
import base64
imgData = 'data:image/png;base64,/9j/4AAQSkZJRgABAQAAAQABAAD后面省略'
imgData = imgData.split(',')[1]
imgData = base64.b64decode(imgData)
with open('test.png', 'wb') as f:
f.write(imgData)
最后才发现是因为自己要转换的这个base64里面带有%2B，所以需要先将%2B这些先进行反转义
import urllib
import base64
imgData = 'data:image/png;base64,/9j/4AAQSkZJRgABAQAAAQABAAD后面省略'
imgData = imgData.split(',')[1]
imgData = urllib.parse.unquote(imgData)
imgData = base64.b64decode(imgData)
with open('test.png', 'wb') as f:
f.write(imgData)
