我想将此图片保存为base64,但是当我尝试这样做时会出现以下错误:
Traceback (most recent call last):
File "E:\Programs\Python\lib\site-packages\django\core\handlers\base.py",line

response = callback(request,*callback_args,**callback_kwargs)

File "E:\Programs\Python\lib\base64.py",line 321,in decodestring
return binascii.a2b_base64(s)
Error: Incorrect padding
bace64:
这是由base64 JavaScript和Filereader生成的,与上传图像时生成代码完全相同.使用Ajax我发送了它.
这个base64自动生成.

最佳答案
您需要删除前导数据:image / png; base64,.只有之后的所有内容都是base64数据.
原文链接:/python/439464.html也许这样的事情(从你的调用堆栈猜测):
_,b64data = request.POST['UplaodFile'].split(',') # [sic]
f.write(decodestring(b64data))
编辑:回答Krasimir的评论:
.split(‘,’)(在本例中)返回一个包含两个字符串的元组,即逗号(,)之前和之后的数据.第一个字符串是’data:image / png; base64′.第二个字符串是base64数据.左侧使用tuple unpacking将这两个字符串分配给名为_和b64data的变量. _只是一个变量,您可以将其重命名为任何有意义的变量. _
is typically used in tuple unpacking to signal “I don’t care about this part”.
