文件太大錯誤處理Nodejs Express Multer

我在ExpressJS上使用Muller。我想限制文件上傳到0.5 MB。文件太大錯誤處理Nodejs Express Multer

var limits = { fileSize: 0.5 * 1024 * 1024 }; 

var upload = multer({ dest: './public/uploads/', limits: limits 
}).single('upl') 

app.post('/',upload, function (req, res) { 
    upload(req, res, function (err) { 
    if (err) { 
      console.log("cs " + err); 
     return 
    } 

      res.end('You new avatar is uploaded') 
    // Everything went fine 
    }) 
})

當文件在0.5 MB，我可以看到「您的新頭像上傳」但是當它在我得到的，

Error: File too large 
    at makeError (C:\Users\Owner\Desktop\nodejs projects\dummy\node_modules\multer\lib\make-error.js:12:13) 
    at abortWithCode (C:\Users\Owner\Desktop\nodejs projects\dummy\node_modules\multer\lib\make-middleware.js:77:22)

    at readableAddChunk (_stream_readable.js:153:18) 
    at PartStream.Readable.push (_stream_readable.js:111:10)

很顯然，我會永遠不希望最終用戶看到這個。我如何正確處理這個問題？

該錯誤被返回到瀏覽器？我很驚訝。 –

這樣的嘗試重寫（去掉「上傳」在前）：

app.post('/', function (req, res) { 
    upload(req, res, function (err) { 
    if (err) { 
     console.log("cs " + err); 
     return 
    } 

    res.end('You new avatar is uploaded') 
    // Everything went fine 
    })

但是，我將如何介紹大小限制？ – user2251234

像你的代碼一樣寫就在app.post（'/'）中刪除上傳中間件 – KibGzr

你說得對。這工作。謝謝。 – user2251234
