使用multer上傳圖像文件時，請求實體太大

Question

var storage = multer.diskStorage({
    destination: (req, file, cb) => {
        cb(null, '/home/innvoot/Desktop/Projects/innmee/innmee_api/classes/uploadedProfilePics')
    },
    filename: (req, file, cb) => {
        cb(null, file.fieldname + "-" + Date.now() + "-" + file.originalname)
    }
});

var upload = multer({storage: storage});     

使用Multer將圖像文件上傳到Express服務器時出錯

我檢查了所有代碼，僅需要大量證據就可以證明我想要的東西，而這將揭示我的大部分項目。

如何處理此錯誤。

你可以嘗試，允許限制ar body解析器嗎

app.use(bodyParser.json({limit:'5mb'})); 
app.use(bodyParser.urlencoded({extended:true, limit:'5mb'}));
