Question

我正在尝试使用node.js将文档文件从本地上传到firebase文件存储。

但我得到的错误如下：

错误：未找到

以下是我的代码。你能不能请任何人帮助我。

const keyFilename="./xxxxxxxx.json"; 
const multer = Multer({
    fileFilter: function(req, file, cb){
        checkFiletype(file, cb)
    },
  storage: Multer.memoryStorage(),
  limits: {
    fileSize: 5 * 1024 * 1024 // no larger than 5mb, you can change as needed.
  }
});

const storage = googleStorage({
  projectId: 'xxxx' ,
  keyFilename :keyFilename
});

const bucket = storage.bucket("gs://xxxx/xxxx");


const uploadImageToStorage = (file) => {
  let prom = new Promise((resolve, reject) => {
    if (!file) {
      reject('No image file');
    }
    console.log('filw',file);
    let newFileName = `${file.originalname}_${Date.now()}`;

    let fileUpload = bucket.file(newFileName);

    const blobStream = fileUpload.createWriteStream({
      metadata: {
        contentType: file.mimetype
      }
    });

    blobStream.on('error', (error) => {
        console.log(error);
      reject('Something is wrong! Unable to upload at the moment.');
    });

    blobStream.on('finish', () => {
      // The public URL can be used to directly access the file via HTTP.
      const url = util.format(`https://storage.googleapis.com/${bucket.name}/${fileUpload.name}`);
      resolve(url);
    });

    blobStream.end(file.buffer);
  });
  return prom;
}

错误：以下是我将文件上传到firebase文件存储区时遇到的错误。

希望对您有用。我从本地上传了一个文件，然后在上传到Firebase存储中之后使用UUID添加了访问令牌，然后生成了下载URL。如果我们点击该生成网址，它将自动下载文件。

 const keyFilename="./xxxxx.json"; //replace this with api key file
    const projectId = "xxx" //replace with your project id
    const bucketName = "xx.xx.appspot.com"; //Add your bucket name
    var mime=require('mime-types');
    const uuidv1 = require('uuid/v1');//this for unique id generation

    //const mime = require('mime');
    const gcs = require('@google-cloud/storage')({
        projectId,
        keyFilename
    });

    const bucket = gcs.bucket(bucketName);

    const filePath = "./sample.odp";
    const remotePath = "/XXXX";
    const fileMime = mime.lookup(filePath);

//we need to pass those parameters for this function
    var upload = (filePath, remoteFile, fileMime) => {

      let uuid = uuidv1();

      return bucket.upload(filePath, {
            destination: remoteFile,
            uploadType: "media",
            metadata: {
              contentType: fileMime,
              metadata: {
                firebaseStorageDownloadTokens: uuid
              }
            }
          })
          .then((data) => {

              let file = data[0];

              return Promise.resolve("https://firebasestorage.googleapis.com/v0/b/" + bucket.name + "/o/" + encodeURIComponent(file.name) + "?alt=media&token=" + uuid);
          });
    }
//This function is for generation download url    
 upload(filePath, remotePath, fileMime).then( downloadURL => {
        console.log(downloadURL);

      });

错误：在firebase文件存储中找不到
