我有这个错误
TypeError[ERR_INVALID_ARG_TYPE]:“chunk”参数必须是string类型或Buffer实例。接收到Object的实例
但我不知道怎么解决：
下面是我的代码库：
router.post('/upload/image', fileUpload.single('file'), function (req, res, next) {
let streamUpload = (req) => {
return new Promise((resolve, reject) => {
let stream = cloudinary.uploader.upload_stream(
(error, result) => {
if (result) {
resolve(result);
} else {
reject(error);
}
}
);
console.log("Images ", req.files);
streamifier.createReadStream(req.files.buffer).pipe(stream);
}).
catch(error => { throw error; });
};
async function upload(req) {
let result = await streamUpload(req);
console.log(result);
}
upload(req);
});
谢谢任何帮助我解决这个问题的人
在使用fileupload.single（“file”）时，应该使用req.file而不是req.files
注意req.file.buffer只能与memorystorage一起使用
const storage = multer.memoryStorage();
cont upload = multer({ storage: storage });
https://www.npmjs.com/package/multer#memorystorage
console.log("Images ", req.file);
streamifier.createReadStream(req.file.buffer).pipe(stream);
https://www.npmjs.com/package/multer
app.post('/profile', upload.single('avatar'), function (req, res, next) {
// req.file is the `avatar` file
// req.body will hold the text fields, if there were any
})
cloudinary.uploader.upload_stream需要两个参数，第一个应该是字符串缓冲区，第二个应该是回调对象（错误，结果）。
您将(error,result)作为唯一的参数传递，我相信这就是导致错误的原因。
cloudinary.uploader.upload_stream('YOUR BUFFER OR STRING HERE', (error, result)=>{})
