Question

我已经阅读了很多关于此的问题，但没有找到有效的解决方案：（

$ appcfg.py download_data --url=http://THING.appspot.com/_ah/remote_api --filename=backup1 .
08:47 PM Application: THING
08:47 PM Downloading data records.
[INFO    ] Logging to bulkloader-log-20120910.204726
[INFO    ] Throttling transfers:
[INFO    ] Bandwidth: 250000 bytes/second
[INFO    ] HTTP connections: 8/second

[INFO    ] Opening database: bulkloader-results-20120910.204726.sql3
[INFO    ] Connecting to THING.appspot.com/_ah/remote_api
[INFO    ] Authentication Failed

所以我对发生的事情有几个疑问：

为什么这不会问我我的密码，几乎所有其他问题我都见过它？是因为我已经上传了我的应用程序的新版本并登录了吗？
为什么有些人必须在他们的命令行中放置application ='s~THING'（对我没用）。
我正在使用gmail地址作为我的管理员，所以大概这意味着它与作为其他类似问题的答案给出的任何OpenID错误无关？
我的app.yaml中有builtins: - remote_api: on（位于此目录中 - 因此是“。”，对吗？），我是否需要设置处理程序？
对/ _ah / remote_api的请求转到我的主（“/.*”）处理程序！这是问题的原因吗？
我该如何解决这些问题？

编辑：塞巴斯蒂安亲切地指出了我正确的方向，但我现在有这个错误：

Answer 1

我仍然有错误（见上文），但https://developers.google.com/appengine/docs/go/tools/uploadingdata似乎涵盖了基础知识正如评论中所建议的那样。感谢那。如果我修复了其他错误，我会更新它。

Answer 2

Go remote_api支持中存在一个小错误。要解决此问题，您可以添加相关索引，也可以使用虚拟Python版本来下载数据。它应该在将来的版本中修复。
