在GAE中，文件“下载”保持下载状态，而不是将内容写入HTML

Question

I'm learning to use cookies in GAE. Every time, I open localhost:8080, a file named just 'download' without any extension downloads. When I open it in notepad, it has "You've been here 0 times." So, instead of writing the content to HTML it downloads a file with the content.

import webapp2

class MainPage(webapp2.RequestHandler):
     def get(self):
         self.response.headers['Content-Type'] = 'type/plain'
         visits  = self.request.cookies.get('visits', 0)
         self.response.out.write("You've been here %s times." % visits)


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

Can please anyone tell me why this is happening and how can I avoid it?

Answer 1

正确的“内容类型”是“文本/纯文本”。

self.response.headers['Content-Type'] = 'text/plain'
