Anybody know of an example of this? I haven't been able to find one in Google's documentation.

推荐答案

get_serving_url已记录在此处.本身并没有端到端示例，但它非常简单:您将其传递给Blob键以及可选的调整大小和裁剪选项，并为您提供URL.您可以在要引用图像的任何地方使用该URL，基础结构将对其提供服务，并对其进行适当的调整和裁剪.

get_serving_url is documented here. There's no end-to-end example per-se, but it's pretty straightforward: You pass it a blob key, along with optional resize and crop options, and it gives you back a URL. You can use that URL anywhere you want to reference the image, and it'll be served up by the infrastructure, resized and cropped appropriately.

请注意，这仅适用于上传到Blobstore的图像.上传到常规数据存储区并存储在BlobProperty中的所有内容都必须调整大小，裁剪并为自己服务.

Note that this is only for images uploaded to the blobstore. Anything uploaded to the regular datastore and stored in a BlobProperty you'll have to resize, crop, and serve yourself.
