javascript - google-cloud TypeError : gcs. bucket 不是函数

Question

我正在尝试实现云功能，但如果我遇到错误像这样要求

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

部署时像这样

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

所以我决定像上面那样使用它，但尝试上传图片时出现错误“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
     })
   });
});

API 在 Cloud Storage Node SDK 的 2.x 版中发生了变化。根据documentation ，您像这样导入 SDK:

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

然后你可以创建一个新的存储对象:

// Creates a client
const storage = new Storage();

然后你可以 Handlebars 伸进一个桶里:

const bucket = storage.bucket()
