如何将包含图像的base64字符串转换为图像格式并将其保存到本地系统。这是我的字符串：
data:image/jpeg;base64,/9j/4AAQSkZJRgABAQEAYABgAAD/4QCSRXhpZgAASUkqAAgAAAAEAA4BAgAbAAAAPgAAADEBAgAHAAAAWQAAABICAwACAAAAAQABAGmHBAABAAAAYAAAAAAAAABwcm9mZXNzaW9uYWwgd29tYW4gcGljdHVyZQBHb29nbGUAAwAAkAcABAAAADAyMjACoAQAAQAAAIQDAAADoAQAAQAAAGQCAAAAAAAA/9sAQwAGBAUGBQQGBgUGBwcGCAoQCgoJCQoUDg8MEBcUGBgXFBYWGh0lHxobIxwWFiAsICMmJykqKRkfLTAtKDAlKCko/9sAQwEHBwcKCAoTCgoTKBoWGigoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgo/8IAEQgCZAOEAwERAAIRAQMRAf/EAB0AAAEFAQEBAQAAAAAAAAAAAAEAAgMEBQYHCAn/x
我需要将此字符串转换为jpg / png / jpeg格式，并作为图像存储在本地系统中。我已经尝试过this问题，但没有得到解决。在html变量中，我得到了一些字符串格式的文本和图像。这是我的代码：
views.py ：
html = request.POST.get('html')
soup = BeautifulSoup(html,features="lxml")
html_image = soup.find_all('img')[0].get('src')
b = html_image.encode()
html_title = soup.get_text()
with open("new_image.png", "wb") as new_file:
new_file.write(base64.decodebytes(b))
