我应该在开发服务器上为Google App Engine BulkLoader添加哪些凭据？

Question

我想问一下,使用Google App Engine BulkLoader类导入数据需要使用哪种凭据

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

然后它要求我提供证书:

请输入localhost的登录凭据

这是一个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.

我不认为我的文件和我的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localhost凭据添加什么？
我也尝试使用Eclipse与Pydev,但我仍然得到相同的消息:(
这是输出:

谢谢!

Answer 1

EUREKA:我找到了使用该bulkloader.py工具的方法,而无需手动输入登录凭据.

以下是两个步骤:

设置您的app.yaml文件.例:

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

你应该把它放在你的- url: .*线路之前app.yaml,否则你永远不会访问/remote_api网址.

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=(您可以使用您想要的任何电子邮件地址,我使用foobar@nowhere.com)
• --passin

指定--email=将禁止"输入凭据"提示,并--passin允许从stdin(即echo 'XX' |发挥作用的位置)读取密码!

请享用!

PS:不要忘记投票,这样Google就可以提供一种更容易使用的方式:问题2440.

Answer 2

我建议您遵循此处给出的建议，我引用：

将其添加到 app.yaml 文件中：

-- url: /loadusers
 script: myloader.py
 login: admin

请注意，如果您在本地开发计算机上运行它，请注释掉最后一行“login:admin”，这样您就不需要凭据来运行bulkloader。

（我的重点）。
