在将图像上传到Firebase之前调整其大小 [英] Resize an image before uploading it to firebase

问题描述

Firebase存储看起来非常酷并且易于使用，但是我想知道是否有一种方法可以在将图像上传到Firebase存储之前调整其大小，例如，在服务器中使用ImageMagick运行一个过程，然后使用Firebase SDK，但我注意到Firebase SDK Server没有存储功能.

Firebase storage looks very cool and easy to use, but I'm wondering if there's a way to resize an image before uploading it to Firebase Storage, e.g., run a proccess using ImageMagick in a server and then run the uploading process using Firebase SDK but I notice there aren't storage functions for Firebase SDK Server.

推荐答案

您还可以使用Firebase Storage + Google Cloud Functions 来上传图像，调整图像大小(使用ImageMagick或类似工具)，然后将其写回Firebase存储.

You can also use Firebase Storage + Google Cloud Functions to upload an image, resize the image (using ImageMagick or similar), and write it back to Firebase Storage.

我有一个在此处一起使用这些示例(尽管我触发了

I have an example using these together here (though I trigger the Cloud Vision API, rather than an image resizer).

一个简短的说明:Firebase Storage没有Node.js客户端，相反，我们建议使用 GCloud-Node 库.

A quick side note: Firebase Storage doesn't have a Node.js client, instead we recommend using the GCloud-Node library.
