RFF*_*RFF 2 python google-app-engine blobstore
我正在阅读Google App Engine中的Blobstore.以下代码来自示例文档.用户选择要上传的文件并单击"提交"后,如何将密钥转换为javascript变量？我可以在一个页面上显示它,但我只想保留它以供以后使用.显然,我是Web编程的新手.
#!/usr/bin/env python

import os
import urllib
from google.appengine.ext import blobstore
from google.appengine.ext import webapp
from google.appengine.ext.webapp import blobstore_handlers
from google.appengine.ext.webapp.util import run_wsgi_app
class MainHandler(webapp.RequestHandler):
def get(self):
upload_url = blobstore.create_upload_url('/upload')
self.response.out.write('<html><body>')
self.response.out.write('<form action="%s" method="POST" enctype="multipart/form-data">' % upload_url)
self.response.out.write("""Upload File: <input type="file" name="file"><br> <input type="submit"
name="submit" value="Submit"> </form></body></html>""")
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.response.out.write('<html><body>')
self.response.out.write(str(blob_info.key()))
self.response.out.write('</body><html>')
def main():
application = webapp.WSGIApplication(
[('/', MainHandler),
('/upload', UploadHandler),
], debug=True)
run_wsgi_app(application)
if __name__ == '__main__':
main()
你可以这样做:
self.response.out.write("""
<html>
<script>
var blobKey = "%s";
</script>
<body>
...
</body>
</html>""" % (blob_info.key(),)
