文件上传中的NodeJS

Question

我使用Multer 1.2.0版本，拥有的NodeJS，每当我试图用base64得到错误--error上传图片：字段值太长 错误

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

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

代码：

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'); 
}); 

无法理解我在哪里丢失，好心建议什么。 预先感谢您。

您可以使用upload.array（'field'）上传任意数量的文件。
