文件上傳中的NodeJS

Question

我使用Multer 1.2.0版本，擁有的NodeJS，每當我試圖用base64得到錯誤--error上傳圖片：字段值太長 錯誤

Error: Field value too long 
at makeError (C:\xampp\htdocs\sitename\node_modules\multer\lib\make-error.js:12:13) 
at abortWithCode (C:\xampp\htdocs\sitename\node_modules\multer\lib\make-middleware.js:77:22)

at Dicer.emit (C:\xampp\htdocs\sitename\node_modules\multer\node_modules\busboy\node_modules\dicer\lib\Dicer.js:80:35) 

代碼：

var multer = require('multer'); 

var storage = multer.diskStorage({ 
    destination: function (req, file, cb) { 
     cb(null, './photos') 
    }, 
    filename: function (req, file, cb) { 
     cb(null, file.fieldname + '-' + Date.now()) 
    } 
}) 

var upload = multer({ storage: storage }).any() 

app.post('/admin/uploadpicture', upload, function(req, res) { 
    res.send('Test'); 
}); 

無法理解我在哪裏丟失，好心建議什麼。 預先感謝您。

您可以使用upload.array（'field'）上傳任意數量的文件。
