如何在功能中包括存储服务帐户密钥 [英] How to include storage service account key in function

问题描述

我正在尝试将服务帐户密钥包含到我的存储功能中，以便能够通过遵循此处的过时示例来获取长期签名的URL

I'm trying to include service account key into my storage function to be able to get long lived signed url by following out of date example here

https://github .com/firebase/functions-samples/blob/b404482342906ee1b46dddb4c75667685ab098a1/generate-thumbnail/functions/index.js#L21

我已经从IAM下载了JSON格式的密钥.我试图将其保存在我的功能旁边

I have downloaded my key from IAM which is in JSON format. I have tried to save it right next to my function

-functions/storage/resizeProfileImg.js

-functions/storage/service-account-credentials.json

-functions/index.js

-functions/admin.js

其中resizeProfileImg.js是我的函数，并且这样调用

where resizeProfileImg.js is my function and call it like this

const { Storage } = require('@google-cloud/storage');
const storage = new Storage({ projectId: projectId ,keyFilename: './service-account-credentials.json'})

但是在部署后，当函数被触发时，我得到了一个错误

but after deployment when the function is triggered then I get an error

错误:ENOENT:没有此类文件或目录，请打开"/srv/service-account-credentials.json"

我甚至试图像这样将其添加为常量

I have even tried to add it in constant like this

const serviceAccountCredentials = require('./accountKey/service-account-credentials.json')

const { Storage } = require('@google-cloud/storage');
const storage = new Storage({ projectId: projectId ,keyFilename: serviceAccountCredentials})

但是我得到一个错误

TypeError:路径必须是字符串.已收到{类型:"service_account"，...

任何想法如何正确执行此操作

Any idea how to do this properly

推荐答案

在Cloud Functions中，当前目录.不在您的源文件所在的位置.这是功能文件夹的部署位置.由于您的凭据文件位于名为存储"的子目录中，因此您需要在路径中使用该文件.

In Cloud Functions, the current directory . isn't where your source file is located. It's where the functions folder was deployed. Since your credentials file is in a subdirectory called "storage", you will need to use that in the path.

const serviceAccountCredentials = require('./storage/service-account-credentials.json')
