python - 使用 appcfg.py App Engine 1.8 for python 上传数据时出现错误 301/404

Question

App Engine SDK 中的 7.5 到 1.8，现在我无法上传数据。 这是错误:

appcfg.py upload_data --url=http://192.168.1.106:8001/ --filename=database --num_threads=4 --rps_limit=500
08:46 PM Uploading data records.
[INFO    ] Logging to bulkloader-log-20130528.204655

[INFO    ] Entities inserted/fetched/modified: 500/second
[INFO    ] Batch Size: 10
Error 301: --- begin server output ---

--- end server output ---

当我使用:/_ah/remote_api 时，这是错误。

appcfg.py upload_data --url=http://192.168.1.106:8001/_ah/remote_api --filename=database --num_threads=4 --rps_limit=500

404 Not Found

我已经使用localhost(使用默认配置)对其进行了测试，结果完全相同。 为什么 1.7.5 版本可以正常工作，但 1.8 版本却无法工作？ 有什么想法吗？

编辑: 我也用bulkloader进行了测试，以使事情变得更容易，这就是结果:

1) 我已使用以下命令将数据库转储到 GAE 中的应用程序中:

bulkloader.py --dump --url=<myapp> --filename=dumpBetaServer 

一切都很好。我有一个名为 dumpBetaServer 的转储。

2)现在，我尝试将此转储恢复到我的开发服务器:

bulkloader.py --restore --url=http://192.168.1.106:8001 --filename=dumpBetaServer --num_threads=1

这就是结果:

感谢您的帮助!

新的 devappserver 在不同的端口启动不同的服务。一般情况下，它将启动三个服务:您的应用程序(默认服务器)、管理服务器(相当于 appengine.google.com 上的管理控制台)和 API 服务器。日志将显示如下内容:

INFO 2013-05-31 16:34:58,397 api_server.py:148] Starting API server at: http://localhost:48392

INFO 2013-05-31 16:34:58,408 dispatcher.py:96] Starting server "default" running at: http://localhost:8080

INFO 2013-05-31 16:34:58,420 admin_server.py:112] Starting admin server at: http://localhost:8000

您需要传递给批量 uploader 的网址是您的应用程序的网址(默认服务器)。
