Html 如何将图像从客户端表单上传到Google云存储桶？,html,google-app-engine,python-2.7,google-cloud-storage,webapp2,Html,Google App Engine,Python 2.7,Google Cloud Storage,Webapp2,有一个表单可以上载图像。现在我想把它存储在谷歌云存储中，然后在页面上打印出来。表格为：- <form action="http://master-engine-799.appspot.com/uploadimage" method="POST" enctype="multipart/form-data"> Upload File: <input type="file" name="file"><br> <input type="submit" name=

有一个表单可以上载图像。现在我想把它存储在谷歌云存储中，然后在页面上打印出来。表格为：-

<form action="http://master-engine-799.appspot.com/uploadimage" method="POST" enctype="multipart/form-data">
Upload File: <input type="file" name="file"><br>
<input type="submit" name="submit" value="Submit"> 
</form>

create_upload_url提供的upload_url是希望用作表单本身上的“操作”的url，而不是/uploadimage。因此，您的HTML表单应该更像：

<form action="CONTENTS_OF_UPLOAD_URL_HERE" method="POST" enctype="multipart/form-data">
  <input type="file" name="file"><br>
  <input type="submit" name="submit" value="Submit">
</form>

形式是这样的

<html>
<body>
<form action="http://your-app-id.appspot.com/myimagehandler" method="POST" enctype="multipart/form-data">
   <input type="file" name="file"><br>
File Name : <input type="text" name="filename1">   <input type="submit" name="submit" value="Submit"> </form>
</body>
</html>

实际上表单在客户端。从表单中，它将调用服务。那么我将如何提供上传url，因为它将被动态创建。。。

class UploadHandler(blobstore_handlers.BlobstoreUploadHandler):
  def post(self):
    upload_files = self.get_uploads('file')  # 'file' is file upload field in the form
    blob_info = upload_files[0]
    self.redirect('/serve/%s' % blob_info.key())

from __future__ import with_statement

import cloudstorage as gcs

import webapp2
import logging

from google.appengine.ext import blobstore
from google.appengine.ext.webapp import blobstore_handlers



def CreateFile(filename,imageFile):
  with gcs.open(filename, 'w', content_type = 'image/jpeg') as f:
    f.write(imageFile)
    f.close()


  blobstore_filename = '/gs' + filename
  return blobstore.create_gs_key(blobstore_filename)

class MyImageHandler(webapp2.RequestHandler):
      def post(self):
        bucket='yourbucketname'
        imageFile = self.request.get('file')
        naemofFile=self.request.get('filename1')
        fileName='/yourbucketname'+'/'+naemofFile
        blob_key = CreateFile(fileName,imageFile)
        logging.info("Blob-Key "+blob_key)
        imageUrl = 'https://%(bucket)s.storage.googleapis.com/%(file)s' % {'bucket':bucket, 'file':naemofFile}

    app = webapp2.WSGIApplication([('/myimagehandler', MyImageHandler)],
                                  debug=True)
