4.but task queue cant get the return string only use

taskqueue.add(url='/worker', params={'key': key},method="GET")

5.so i have to edit the worker hander like this :

class CounterWorker(BaseRequestHandler):
    def get(self): 
        self.render_template('ajax.html')

and the ajax.html is :

<script type="text/javascript">
    $.get("http:/www.digu.com/api", function(data){
      $.post("/save",{ajax:data})
    })
</script>

You can use app engine’s urlfetch library to fetch a url from another server (ie the blog you want to fetch a value from).
