来自ImagesService.getServingUrl的URL持续多久 [英] How long does URL from ImagesService.getServingUrl last

问题描述

我正在App Engine中使用blobstore和imagesService。我想知道从imagesService.getServingUrl（blobKey）获取的URL会持续多久。如果我使用它来存储用户个人资料图片，我可以将此URL存储在用户中，还是应该存储BlobKey并在每次需要照片时都获取servingUrl？

I'm working with the blobstore and imagesService in App Engine. I'm wondering how long a URL I get from imagesService.getServingUrl(blobKey) will last. If I'm using this to store a users profile picture, can I store this URL in the user or should I store the BlobKey and get the servingUrl each time i need the picture?

推荐答案

URL将无限期地持续。无论如何，您仍然应该仍然存储blobkey，否则，您将无法在不再需要时删除Blob，也无法获取备用图片提供网址。

The URL will last indefinitely. You should definitely still store the blobkey anyway, though, or you will have no way to delete blobs once you no longer need them, or to get alternate image serving URLs.
