使用 multer 上传图像文件时请求实体太大

Question

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

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

使用 multer 将图像文件上传到快递服务器时出错

我查看了我所有的代码，并且只需要大量的证据来证明我想要的更多，这将揭示我的大部分项目。

如何处理这个错误。

你能不能试试，允许限制ar body parser

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