Blobstore图像消失在Google App Engine开发服务器上 [英] Blobstore Images Disappearing on Google App Engine Development Server

问题描述

我在我的网站上使用了App Engine的高性能图片服务，并且我可以在本地计算机和生产环境中正常运行，例如，我可以上传图片并使用get_serving_url成功显示图片一团糟。但是，这些图像似乎并未在我的开发服务器上持续存在，即从计算机重新启动回来后，图像不再显示。开发服务器吐出：

I'm using App Engine's high performance image serving on my site, and I'm able to get everything working properly on both my local machine and in production i.e. I can upload an image and successfully display the images using get_serving_url on the blob key. However, these images don't seem to persist on my development server, i.e. after I come back from a computer restart, the images no longer show up. The development server spits out:

images_service_pb.ImagesServiceError.BAD_IMAGE_DATA

images_service_pb.ImagesServiceError.BAD_IMAGE_DATA

我猜测其实是因为潜在的斑点不再存在（虽然这只是一个预感）。我的数据存储的其余部分仍然完好无损，因为我正在使用启动设置--datastore_path来确保我的数据持续存在。我还需要使用一个单独的标志来坚持blob吗？或者在这里有一个单独的问题，我错过了？

which I'm guessing is actually because the underlying blobs are no longer there (although this is just a hunch). The rest of my datastore is still intact though, as I'm using the launch setting "--datastore_path" to ensure my data persists. Is there a separate flag I need to be using to persist the blobs as well? Or is there a separate problem here that I'm missing?

推荐答案

您必须使用 - blobstore_path = DIR ：

--blobstore_path=DIR       Path to directory to use for storing Blobstore
                           file stub data.

您可以看到所有输入 dev_appserver.py --help 在命令行中。

You can see all options typing dev_appserver.py --help in the command line.
