node.js - Firebase 有上传限制吗？

Question

我似乎无法使用 Busboy 的 Firebase 功能在 Firebase 存储中上传超过 5MB 的文件。错误返回:

ResumableUploadError: A resumable upload could not be performed. The directory, /tmp/.config, is not writable. You may try another upload, this time setting options.resumable to false.

小于 5mb 即可工作。如果 5mb 是限制，有解决办法吗？

这是我的代码

  const functions = require('firebase-functions');
  const admin = require('firebase-admin');
  const express = require('express');

  var serviceAccount = require('./serviceAccount.json');
  admin.initializeApp(
  {credential: admin.credential.cert(serviceAccount),
    databaseURL:dbURL})
  let gcs = admin.storage();
  const bucketName = 'bucket name';

  const app = express();
  const api = functions.https.onRequest(app);

  app.post('/addImage',(req,res)=>{

    const busboy = new Busboy({ headers: req.headers });
    let uploadData = null;
    let origFileName;

    busboy.on("file", (fieldname, file, filename, encoding, mimetype) => {
      origFileName = filename
      const filepath = path.join(os.tmpdir(), filename);
      uploadData = { file: filepath, type: mimetype };
      file.pipe(fs.createWriteStream(filepath));
    });

    let formData = new Map();
    busboy.on('field', function(fieldname, val) {
      formData.set(fieldname, val);
    });

    busboy.on("finish", () => {
      const bucket = gcs.bucket(bucketName);
      let uuid = UUID();
      let dataURL = ''
      let company = formData.get('company');
      let eventCode = formData.get('eventCode');
      let type = formData.get('type');
      bucket
        .upload(uploadData.file, {
          uploadType: "media",
          metadata: {
            metadata: {
              contentType: uploadData.type,
              firebaseStorageDownloadTokens: uuid
            }
          },
          destination: company+"/"+eventCode+"/"+type+"/"+origFileName
        }).then(data=>{

          let file = data[0];
          dataURL = "https://firebasestorage.googleapis.com/v0/b/" + bucket.name + "/o/" + encodeURIComponent(file.name) + "?alt=media&token=" + uuid;


          return res.status(200).send(result);
        })
        .catch(error =>{
          console.log("error",error)
          if (err) return res.status(500).send('Internal Server Error')
        })

    });
    busboy.end(req.rawBody);
  })

您的用例是否需要 options.resumable=true？如果这不会破坏您的用例，请将其切换为 false，它应该适合您。

Here您有关于 createWriteStream 的更多信息。

Resumable uploads are automatically enabled and must be shut off explicitly by setting options.resumable to false.

Resumable uploads require write access to the $HOME directory. Through config-store, some metadata is stored. By default, if the directory is not writable, we will fall back to a simple upload. However, if you explicitly request a resumable upload, and we cannot write to the config directory, we will return a ResumableUploadError.

There is some overhead when using a resumable upload that can cause noticeable performance degradation while uploading a series of small files. When uploading files less than 10MB, it is recommended that the resumable feature is disabled.

希望这有帮助。

编辑:

默认情况下它是启用的，您必须将其作为在 createWriteStream 中设置为 false 的选项传递，尝试这样做并查看它是否允许您上传。

例如像这样。

您必须像以前一样将文件路径传递给它，然后添加可恢复选项。

.createWriteStream({
          resumable: false,
          metadata: {
            contentType: 'text/plain',
          },
        })
