问题描述

我只想使用表单上传图片(JPG),然后将该图像发送到RackspaceCloud Files或AmazonS3。

I simply want to upload an image (JPG) using a form, then send that image to Rackspace 'Cloud Files' or Amazon 'S3'.


  • 无法处理该文件。

  • 不保存到磁盘,所有内容(托管在一个云服务器)

  • 图像大小不会超过75kb

/ strong>(两个警告):

Update (Two Caveats):


  • 一:在手机应用发布数据时也需要工作。

  • 二:需要发送到Rackspace Cloud Files以及S3(以CF开头)。

下面的代码工作,但它是WAY太重了。

The code below works but it is way WAY too heavy.

import cloudfiles as cf
def uploadImage(request, id):

  cf_con = cf.get_connection(username='YYY', api_key='XXX', serviceNet=True)
  container = cf_con.get_container('container_name')

  file = request.FILES["item_photo"]
  f = StringIO(file.read())
  f = Image.open(f)

  ### Only works if I resize for some reason, otherwise uploads a broken file
  image = f.resize((600,600), Image.ANTIALIAS)
  o = StringIO()
  image.save(o, "JPEG", quality=80)
  image = o.getvalue()

  file_name  = "%s/%s" % (id, '600x600.jpeg')

  ### This simply uploads to Rackspace Cloud files.
  put_file(container, file_name, image)

非常感谢
希望一切都很好...

Thanks so much, Hope all is well ...

推荐答案

忽略python所有在一起,直接上传到s3?

How about ignoring python all together and just uploading directly to s3?

您可以配置您的s3桶,以禁止上传任何大于$ X字节的文件。

You can configure your s3 bucket to disallow uploading any files larger than $X bytes.

这是一个简单的例子,说明直接上传到s3(并忽略了你的图像宽度/高度条件)

Here's a simple example to illustrate uploading directly to s3 (and ignoring your image width/height conditions)

http://sente.cc/upload_to_s3.html

代码:

<html>
  <head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
  </head>
  <body>
  <h3>refresh the page after you've submitted to see your new image</h3>
    <div style="width:300px">
    <form action="http://s3.amazonaws.com/dev.sente" method="post" enctype="multipart/form-data">
      <fieldset>
      <input type="hidden" name="acl" value="public-read" /> <br />
      <i>name of key:</i><input type="text" name="key" readonly="true" value="image.jpg" /> <br />
      <input name="file" type="file" /> <br />
      <input name="submit" value="Upload" type="submit" />
    </fieldset>
    </form>
  </div>
    <br>
    <a href="http://s3.amazonaws.com/dev.sente/image.jpg">http://s3.amazonaws.com/dev.sente/image.jpg</a>
      <br>
      <a href="http://s3.amazonaws.com/dev.sente/image.jpg"><img src="http://s3.amazonaws.com/dev.sente/image.jpg"></a>
    </a>
  </body>
</html>
