我们如何使用 firebase 图像文件并使用 get_Serving_URL 调整它们的大小 [英] how can we use firebase image file and resize them using get_Serving_URL

问题描述

我刚开始使用谷歌云服务并发现以下只能使用 blob 实现，但我想使用云存储中的图像名称.

I just started using google cloud services and found that the following can be only implemented using blob but i want to use image name from cloud storage.

如果有的话，有没有办法使用servingURL来调整图像的大小我如何实现它，即我如何从云存储中提供存储桶名称和图像名称?

Is there a way to resize the images using servingURL if so how can i implement it i.e. how can i give the bucket name and image name from cloud storage ?

并构造URL并传递参数

and construct the URL and pass the parameters
