google-app-engine – Cloud Shell上dev_appserver上的Google Cloud存储

2024年1月12日 263次阅读

我正在尝试使用GAE的Google云端存储,部署后一切正常.但是,我无法让存储在Google Cloud
Shell上运行的开发服务器上运行.

我正在使用cloudstorage API并且我理解dev_appserver应该访问与已部署的应用程序相同的存储桶.对我来说,使用本地数据也可以.

dev_appserver.py调用开发服务器.

我玩过未记录的default_gcs_bucket_name标志,但没有运气.

我使用gcloud init设置了cloud shell以使用正确的项目.我也尝试过使用新的google.cloud.storage API而没有运气.

如果我运行此处提供的示例,则会触发与下面引用的相同的错误：App Engine and Google Cloud Storage Sample.

任何人？

编辑：无论是否提供有效或无效的存储桶名称,我都会收到相同的错误.

的app.yaml

runtime: python27
api_version: 1
threadsafe: true

builtins:
- remote_api: on

handlers:
- url: /.*
  script: main.app

main.py

import logging
import cloudstorage as gcs
import webapp2
from google.appengine.api import app_identity

class MainPage(webapp2.RequestHandler):
    def get(self):
        self.response.headers['Content-Type'] = 'text/plain'
        bucket_name = "xxxx-xxxxxx.appspot.com"     
        stats = gcs.listbucket('/'+bucket_name) 
        for stat in stats:
          self.response.write(repr(stat) + '')        

app = webapp2.WSGIApplication([
    ('/', MainPage),
], debug=True)

最佳答案 按照
How the Application Default Credentials work中的说明进行操作(条件1)

它涉及将GOOGLE_APPLICATION_CREDENTIALS env变量设置为指向有效的json凭证文件.
对于这些测试,我刚刚创建了一个新的选择App Engine默认服务帐户：

《google-app-engine – Cloud Shell上dev_appserver上的Google Cloud存储》

……而且效果很好.

根据How the Application Default Credentials work运行gcloud auth应用程序 – 默认登录(条件2)也应该解决问题,但我还没能使它在Cloud Shell上运行,它失败了同样的“访问令牌相关”错误:-(
