- by zjm1126
this is my code :
import os
from google.appengine.ext import webapp
from google.appengine.ext.webapp import template
from google.appengine.ext.webapp.util import run_wsgi_app
from google.appengine.ext import db
#from login import htmlPrefix,get_current_user
class MyModel(db.Model):
blob = db.BlobProperty()
class BaseRequestHandler(webapp.RequestHandler):
def render_template(self, filename, template_args=None):
if not template_args:
template_args = {}
path = os.path.join(os.path.dirname(__file__), 'templates', filename)
self.response.out.write(template.render(path, template_args))
class upload(BaseRequestHandler):
def get(self):
self.render_template('index.html',)
def post(self):
file=self.request.get('file')
obj = MyModel()
obj.blob = db.Blob(file.encode('utf8'))
obj.put()
self.response.out.write('upload ok')
class download(BaseRequestHandler):
def get(self):
#id=self.request.get('id')
o = MyModel.all().get()
#self.response.out.write(''.join('%s: %s <br/>' % (a, getattr(o, a)) for a in dir(o)))
self.response.out.write(o)
application = webapp.WSGIApplication(
[
('/?', upload),
('/download',download),
],
debug=True
)
def main():
run_wsgi_app(application)
if __name__ == "__main__":
main()
my index.html is :
<form action="/" method="post">
