Google App Engine 出現 Stripped prohibited headers from URLFetch request: ['Host']

今天發現Google App Engine 出現

urlfetch_stub.py:504 Stripped prohibited headers from URLFetch request: ['Host']

的解法，原來只要把 urllib 或 urllib2 改成 urlfetch 即可~

源自 StackOverFlow

Since urllib and urllib2 are just wrappers for urlfetch, I might also suggest the following:

from google.appengine.api import urlfetch
result = urlfetch.fetch(url)

不過這只是一個Warning，不是 Error ，所以沒解決也沒關係~
