我需要使用Django從url保存圖片。 所以我確實喜歡這個教程,但是我遇到了一個奇怪的錯誤。python:從url保存圖片時出錯
page = requests.get(url)
if page.status_code != 200 or not page.content:
assert 0, 'can\'t download article image'
image = image_content_file(page.content)
article.image.save('%i.jpg' % article.pk, image, save=False)
我的文章型號:
class Article(models.Model):
title = models.CharField(max_length=255)
content = models.TextField(blank=True)
image = models.ImageField(blank=True, upload_to='upload/article_image')
date_created = models.DateTimeField(null=True, blank=True, db_index=True)
我已經創建upload/article_image
文件夾,並設置其權限爲777
我image_content_file
功能:
def image_content_file(img_content):
input_file = StringIO(img_content)
output_file = StringIO()
img = Image.open(input_file)
if img.mode != "RGB":
img = img.convert("RGB")
img.save(output_file, "JPEG")
return ContentFile(output_file.getvalue())
但我得到這個錯誤
image = image_content_file(page.content)
File "/home/yital9/webservers/binarybits/binarybits/../binarybits/utils/img.py", line 24, in image_content_file
img.save(output_file, "JPEG")
File "/usr/local/lib/python2.7/dist-packages/PIL/Image.py", line 1439, in save
save_handler(self, fp, filename)
File "/usr/local/lib/python2.7/dist-packages/PIL/JpegImagePlugin.py", line 471, in _save
ImageFile._save(im, fp, [("jpeg", (0,0)+im.size, 0, rawmode)])
File "/usr/local/lib/python2.7/dist-packages/PIL/ImageFile.py", line 481, in _save
e = Image._getencoder(im.mode, e, a, im.encoderconfig)
File "/usr/local/lib/python2.7/dist-packages/PIL/Image.py", line 399, in _getencoder
return apply(encoder, (mode,) + args + extra)
TypeError: function takes at most 9 arguments (11 given)
你能告訴我什麼問題嗎?
你爲什麼不使用的urllib .urlretrieve(「http://example.com/img.jpg」)? – mou
