问题描述

我有一个使用GCS进行文件存储的python GAE应用程序。它在生产环境中可以很好地工作,但是在dev_appserver上本地运行时完全失败。



任何有助于深入了解此内容的人都会受益。



谢谢。

gcs_file = gcs.open(文件名,'w',content_type = content_type)
gcs_file.write(文件)
gcs_file.close()

解决方案

我遇到了同样的问题。
我使用google_appengine_1.8.7(来自zip)和appengine-gcs-client-python-r127.zip。

终点_ah / gcs不在dev_appserver中处理。



实际上,我认为它与此更改有关( https://code.google.com/p/appengine-gcs-client/source/detail?r=125 )和似乎是GAE 1.8.7。不符合这种变化。



我使用这个appengine-gcs-client-python-r65.zip,它现在工作正常!


I have a python GAE app that uses GCS for file storage. It works perfectly in production, but fails completely when running locally on dev_appserver.

Any help getting to the bottom of this would be appreciated.

Thanks.

解决方案

I got the same problem. I am using google_appengine_1.8.7 (from zip) and appengine-gcs-client-python-r127.zip.

The end point "_ah/gcs" is not handled in dev_appserver.

In fact i think it is related to this change (https://code.google.com/p/appengine-gcs-client/source/detail?r=125) and seems that the GAE 1.8.7. is not align with this change.

I use this appengine-gcs-client-python-r65.zip and it works fine now!
