python - 我应该在开发服务器上为 Google App Engine BulkLoader 输入哪些凭据？

Question

我想问一下，使用 Google App Engine BulkLoader 类导入数据需要提供哪种凭证

appcfg.py upload_data --config_file=models.py --filename=listcountries.csv --kind=CMSCountry --url=http://localhost:8178/remote_api vit/

然后它要求我提供凭据:

Please enter login credentials for localhost

这是 models.py 内容的提取，我使用这个 listcountries.csv文件

class CMSCountry(db.Model):
  sortorder = db.StringProperty()
  name = db.StringProperty(required=True)
  formalname = db.StringProperty()
  type = db.StringProperty()
  subtype = db.StringProperty()
  sovereignt = db.StringProperty()
  capital = db.StringProperty()
  currencycode = db.StringProperty()
  currencyname = db.StringProperty()
  telephonecode = db.StringProperty()
  lettercode = db.StringProperty()
  lettercode2 = db.StringProperty()
  number = db.StringProperty()
  countrycode = db.StringProperty()

class CMSCountryLoader(bulkloader.Loader):
  def __init__(self):
    bulkloader.Loader.__init__(self, 'CMSCountry',
                           [('sortorder', str),
                            ('name', str),
                            ('formalname', str),
                            ('type', str),
                            ('subtype', str),
                            ('sovereignt', str),
                            ('capital', str),
                            ('currencycode', str),
                            ('currencyname', str),
                            ('telephonecode', str),
                            ('lettercode', str),
                            ('lettercode2', str),
                            ('number', str),
                            ('countrycode', str)
                            ])
loaders = [CMSCountryLoader] 

每次尝试输入电子邮件和密码都会导致“身份验证失败”，因此我无法将数据导入开发服务器。

我认为我的文件和模型都没有任何问题，因为我已成功将数据上传到 appspot.com 应用程序。
那么我应该为本地主机凭据输入什么？
我还尝试将 Eclipse 与 Pydev 一起使用，但我仍然收到相同的消息:(
这是输出:

谢谢!

Answer 1

EUREKA:我找到了无需手动输入登录凭据即可使用 bulkloader.py 工具的方法。

这里有两个步骤:

---

设置您的 app.yaml 文件。示例:

- url: /remote_api
  script: $PYTHON_LIB/google/appengine/ext/remote_api/handler.py
  login: admin

你应该把它放在 app.yaml 中的 - url: .* 行之前，否则你将永远无法访问 /remote_api url .

请注意，我已经离开了 login: admin 部分，因为删除它是一种非常糟糕的做法，因为您可能会将其部署到生产中...

---

2 启动此命令(根据您的需要进行调整)。

echo 'XX' | python2.5 ../google_appengine/bulkloader.py --dump --kind=NAMEOFMODEL --url=http://localhost:8080/remote_api --filename=FILENAME --app_id=APPID --email=foobar@nowhere.com --passin .

诀窍是使用这两个参数的组合:

• --email=(你可以输入任何你想要的电子邮件地址，我使用foobar@nowhere.com)
• --passin

指定 --email= 将抑制“输入凭据”提示，而 --passin 将允许从 stdin 读取密码(这就是 echo 'XX' | 发挥作用的地方!)

---

尽情享受吧!
