Decodificó los datos usando el códec base64 y luego escríbalos en el sistema de archivos.
# In Python 2.7
fh = open("imageToSave.png", "wb")
fh.write(img_data.decode('base64'))
fh.close()
# or, more concisely using with statement
with open("imageToSave.png", "wb") as fh:
fh.write(img_data.decode('base64'))
Modernizando este ejemplo a Python 3, que eliminó la compatibilidad con códecs arbitrarios de string/ bytes .encode() y .decode() funciones:
# For both Python 2.7 and Python 3.x
import base64
with open("imageToSave.png", "wb") as fh:
fh.write(base64.decodebytes(img_data))
Si el imagestr era datos de mapa de bits (que ahora sabemos que no lo es), podría usar esto
imagestr está codificado en base64 stringwidth es el ancho de la imagenheight es la altura de la imagen
from PIL import Image
from base64 import decodestring
image = Image.fromstring('RGB',(width,height),decodestring(imagestr))
image.save("foo.png")
Dado que imagestr es solo los datos png codificados
from base64 import decodestring
with open("foo.png","wb") as f:
f.write(decodestring(imagestr))
También puede guardarlo en un string búfer y luego haz lo que quieras con él,
import cStringIO
data = json.loads(request.POST['imgData']) # Getting the object from the post request
image_output = cStringIO.StringIO()
image_output.write(data.decode('base64')) # Write decoded image to buffer
image_output.seek(0) # seek beginning of the image string
# image_output.read() # Do as you wish with it!
En django, puede guardarlo como un archivo cargado para guardarlo en un modelo:
from django.core.files.uploadedfile import SimpleUploadedFile
suf = SimpleUploadedFile('uploaded_file.png', image_output.read(), content_type='image/png')
O envíelo como un correo electrónico:
email = EmailMessage('Hello', 'Body goes here', '[email protected]',
['[email protected]', ])
email.attach('design.png', image_output.read(), 'image/png')
email.send()
