我正在尝试从计算引擎实例中的拉取队列中租用应用程序引擎任务,但它一直出现此错误:
{
"error": {
"errors": [
{
"domain": "global",
"reason": "forbidden",
"message": "you are not allowed to make this api call"
}
],
"code": 403,
"message": "you are not allowed to make this api call"
}
}
这是我正在使用的代码:
import httplib2, json, urllib
from oauth2client.client import AccessTokenCredentials
from apiclient.discovery import build
def FetchToken():
METADATA_SERVER = ('http://metadata/computeMetadata/v1/instance/service-accounts')
SERVICE_ACCOUNT = 'default'
http = httplib2.Http()
token_uri = '%s/%s/token' % (METADATA_SERVER, SERVICE_ACCOUNT)
resp, content = http.request(token_uri, method='GET',
body=None,
headers={'Metadata-Flavor': 'Google'})
print token_uri
print content
if resp.status == 200:
d = json.loads(content)
access_token = d['access_token'] # Save the access token
credentials = AccessTokenCredentials(d['access_token'],
'my-user-agent/1.0')
autho = credentials.authorize(http)
print autho
return autho
else:
print resp.status
task_api = build('taskqueue', 'v1beta2')
lease_req = task_api.tasks().lease(project='project-name',
taskqueue='pull-queue',
leaseSecs=30,
numTasks=1)
result = lease_req.execute(http=FetchToken()) ####ERRORS HERE
item = result.items[0]
print item['payload']
这似乎是一个身份验证问题,但如果我使用胡说八道的项目名称执行相同的租赁请求,它会给我完全相同的错误,所以我无法确定。
我还启动了启用任务队列的实例。
任何帮助将不胜感激
