[英]How to upload an image from web into Google Cloud Storage?
I am working on a news app and would like to cache the news images on my own google cloud storage. 我正在开发新闻应用程序,并希望将新闻图像缓存在我自己的Google云存储中。
I am planning to use Flask on GAE. 我打算在GAE上使用Flask。 All examples I have found relate to upload a file from user's browser into cloud storage. 我发现的所有示例都与将文件从用户的浏览器上传到云存储有关。
What is the best way to obtain an image via an url and upload it to google cloud storage? 通过网址获取图片并将其上传到Google云存储的最佳方法是什么? I hope this makes sense, please feel free to suggest improvements. 我希望这是有道理的,请随时提出改进建议。 Many Thanks 非常感谢
def main():
bucket_name = os.environ.get('BUCKET_NAME',
app_identity.get_default_gcs_bucket_name())
bucket = '/' + bucket_name
filename = bucket + '/image_name'
image_url = "http://news.com/crash.jpg"
try:
create_file(image_url, filename)
except Exception, e:
logging.exception(e)
return "Success", 201
def create_file(image_url, filename):
image = cStringIO.StringIO(urllib.urlopen(image_url).read()) // Not sure about this
img = Image.open(image)
write_retry_params = gcs.RetryParams(backoff_factor=1.1)
gcs_file = gcs.open(filename,
'w',
content_type='image/jpeg', // ???? Is MIME type correct?
options={'x-goog-acl': 'public'},
retry_params=write_retry_params)
gcs_file.write(img)
gcs_file.close()
Try this: 尝试这个:
import urllib2
from google.appengine.api import images
import cloudstorage as gcs
image_at_url = urllib2.urlopen(url)
content_type = image_at_url.headers['Content-Type']
filename = #use your own or get from file
image_bytes = image_at_url.read()
image_at_url.close()
image = images.Image(image_bytes)
# this comes in handy if you want to resize images:
if image.width > 800 or image.height > 800:
image_bytes = images.resize(image_bytes, 800, 800)
options={'x-goog-acl': 'public-read', 'Cache-Control': 'private, max-age=0, no-transform'}
with gcs.open(filename, 'w', content_type=content_type, options=options) as f:
f.write(image_bytes)
f.close()
