google-cloud TypeError:gcs.bucket不是函数 [英] google-cloud TypeError: gcs.bucket is not a function

问题描述

我正在尝试实现云功能，但是如果我遇到错误 要求这样

I am trying to implement cloud function but getting error if i require it like this

   var storage =require('@google-cloud/storage')(); 

部署时

像这样

like this when deploying

var storage = require('@google-cloud/storage');

所以我决定使用上述方法，但是尝试上传图片时出现错误"TypeError:gcs.bucket不是函数"

so i resolved to using it as above but tried uploading a picture i am getting error "TypeError: gcs.bucket is not a function"

const os = require('os');
const path = require('path');

///

exports.onFileChange = functions.storage.object().onFinalize((event) => {
 const bucket = event.bucket;
 const contentType = event.contentType;
 const filePath = event.name;
 console.log('Changes made to bucket');

///

 if(path.basename(filePath).startsWith('renamed-')){
     console.log("File was previously renamed");
     return;
 }
 const gcs = storage({
    projectId: 'clfapi'
  });

///

 const destBucket = gcs.bucket(bucket);
 const tmFiilePath = path.join(os.tmpdir(), path.basename(filePath));
 const metadata = {contentType: contentType};

///

 return destBucket.file(filePath).download({
     destination: tmFiilePath
 }).then(() => {
     return destBucket.upload(tmFiilePath, {
         destination: 'renamed-' + path.basename(filePath),
         metadata: metadata
     })
   });
});

推荐答案

API在Cloud Storage节点SDK的2.x版本中进行了更改.根据文档 ，您可以这样导入SDK:

The API changed in version 2.x of the Cloud Storage node SDK. According to the documentation, you import the SDK like this:

// Imports the Google Cloud client library
const {Storage} = require('@google-cloud/storage');

然后您可以创建一个新的存储对象:

Then you can create a new Storage object:

// Creates a client
const storage = new Storage({
  projectId: projectId,
});

然后您可以进入水桶:

const bucket = storage.bucket()
