下本地工作，但不是urllib2的錯誤時：AppEngine上
import urllib
import urllib2
import simplejson as json
url = 'https://www.googleapis.com/rpc'
requests = [{
'method': 'freebase.text.get',
'apiVersion': 'v1',
'params': {
'id': ['en','bob_dylan']
}
},{
'method': 'freebase.text.get',
'apiVersion': 'v1',
'params': {
'id': ['en','blade_runner']
}
}]
headers = { 'Content-Type': 'application/json' }
req = urllib2.Request(url, json.dumps(requests), headers)
response = urllib2.urlopen(req)
print response.read()
在部署時，它拋出以下錯誤：
class 'urllib2.HTTPError': HTTP Error 404: Not Found
Traceback (most recent call last):

這可能涉及到這個問題：freebase api error on deployment to appengine: DownloadError: ApplicationError: 2在這種情況下，在請求中添加api鍵可以修復它。雖然我嘗試添加一個鍵（使用網址抓取）導致錯誤：
{u'code': 100, u'message': u'Invalid API Key (Key not found)', u'stat': u'fail'}.
我註冊遊離鹼的服務，並增加了瀏覽器的應用程序來查詢的簡單API密鑰：「&鍵= apikeystringhere」。我已經將關鍵問題作爲單獨問題添加了：Setup api key for freebase queries from appengine
