图片上传错误：TypeError [ERR_INVALID_ARG_TYPE]：“路径”参数必须是字符串类型。 接收类型未定义

Question

我正在尝试使用邮递员将图像上传到 firebase。 随着firebase serve运行，我向我的路由发送了一个 post 请求以及 Authorization 标头和图像文件，但在控制台中收到以下错误：

类型错误 [ERR_INVALID_ARG_TYPE]：“路径”参数必须是字符串类型。 接收类型未定义

 exports.uploadImage = (req, res) => { const BusBoy = require('busboy') const path = require('path') const os = require('os') const fs = require('fs') const busboy = new BusBoy({ headers: req.headers }) let imageFileName let imageToBeUploaded = {} busboy.on('file', (fieldname, file, filename, encoding, mimetype) => { console.log(fieldname, filename, encoding, mimetype) if (mimetype !== 'image/jpeg' && mimetype !== 'image/png') { return res.status(400).json({ error: '❌ Wrong file type submitted' }) } const imageExtension = filename.split('.')[filename.split('.').length - 1] imageFileName = `${Math.round( Math.random() * 1000000000000 )}.${imageExtension}` const filepath = path.join(os.tmpdir(), imageFileName) imageToBeUploaded = { filepath, mimetype } file.pipe(fs.createWriteStream(filepath)) }) busboy.on('finish', () => { admin .storage() .bucket(config.storageBucket) .upload(imageToBeUploaded.filpath, { resumable: false, metadata: { metadata: { contentType: imageToBeUploaded.mimetype, }, }, }) .then(() => { const imageUrl = `https://firebasestorage.googleapis.com/v0/b/${config.storageBucket}/o/${imageFileName}?alt=media` return db.doc(`/users/${req.user.handle}`).update({ imageUrl }) }) .then(() => { return res.json({ message: '✅ Image uploaded successfully' }) }) .catch((err) => { console.error(err) return res.status(500).json({ error: err.code }) }) }) busboy.end(req.rawBody) }

Answer 1

问题是您在upload()的参数中输入了imageToBeUploaded.filpath ，但您打算输入imageToBeUploaded.filepath 。 缺少一个“e”，这使得整个表达式未定义。
