如何在Python 2.7中使用Google App Engine遠程API和聯合登錄？

Question

當使用聯合登錄時，Google App Engine的Remote API爲not supported。但是，顯然有可能在Python 2.5使用它，如下所述：

基於該解決方案，我創建了下面的Python 2.7的代碼的文章下面的評論：

應用.yaml：

application: my_application 
version: 1 
runtime: python27 
api_version: 1 
threadsafe: true 

builtins: 
- appstats: on 
#- remote_api: on 

handlers: 
- url: /remoteapi.* 
    script: remote_api.app 
- url: /.* 
    script: main.app 
    secure: never 

remote_api.py：

from google.appengine.ext.remote_api import handler 
from google.appengine.ext import webapp 
import re 

MY_SECRET_KEY = 'secret' 
cookie_re = re.compile('^"?([^:]+):.*"?$') 

class ApiCallHandler(handler.ApiCallHandler): 
    def CheckIsAdmin(self): 
     login_cookie = self.request.cookies.get('dev_appserver_login', '') 
     match = cookie_re.search(login_cookie) 
     if (match and match.group(1) == MY_SECRET_KEY 
      and 'X-appcfg-api-version' in self.request.headers): 
      return True 
     else: 
      self.redirect('/_ah/login') 
      return False 


app = webapp.WSGIApplication([('.*', ApiCallHandler)]) 

當我運行remote_api_shell命令：

remote_api_shell.py -s my_application.appspot.com/remoteapi 

返回此錯誤：

Traceback (most recent call last): 
    File "remote_api_shell.py", line 133, in <module>

    File "C:\Python27\lib\urllib2.py", line 400, in open 
    response = meth(req, response) 
    File "C:\Python27\lib\urllib2.py", line 513, in http_response 
    'http', request, response, code, msg, hdrs)

    result = func(*args) 
    File "C:\Python27\lib\urllib2.py", line 521, in http_error_default 
    raise HTTPError(req.get_full_url(), code, msg, hdrs, fp) 
urllib2.HTTPError: HTTP Error 302: Found 

什麼是錯我的代碼？使用聯合登錄可以在Google App Engine上的Python 2.7中使用Remote API嗎？

Answer 1

代碼沒有問題。像這樣運行remote_api_shell命令：

remote_api_shell.py -s my_application.appspot.com -p /remoteapi 

當提示輸入電子郵件地址，填寫的MY_SECRET_KEY值。密碼無關緊要。
