MalformedXML：您提供的XML沒有得到很好的形成或沒有驗證對我們發佈的架構

Question

我有這個奇怪的問題與AWS S3工作時。我正在研究可以將圖像存儲到AWS存儲桶的應用程序。使用Multer作爲中間件和S3FS庫來連接並上傳到AWS。

但下面的錯誤彈出，當我嘗試上傳的內容。

「MalformedXML：您提供的XML沒有得到很好的形成或沒有驗證對我們敬上 HED模式」

Index.js

var express = require('express'); 
var router = express(); 
var multer = require('multer'); 
var fs = require('fs'); 
var S3FS = require('s3fs'); 
var upload = multer({ 
    dest: 'uploads' 
}) 
var S3fsImpl = new S3FS('bucket-name', { 
    region: 'us-east-1', 
    accessKeyId: 'XXXXXXXXXXXX', 
    secretAccessKey: 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX' 
}); 

/* GET home page. */ 
router.get('/', function (req, res, next) { 
    res.render('profile', { 
    title: 'Express' 
    }); 
}); 

router.post('/testupload', upload.single('file'), function (req, res) { 
    var file = req.file; 
    console.log(file); 

    var path = req.file.path; 
    var stream = fs.createReadStream(path); 
    console.log(stream); 

    S3fsImpl.writeFile(file.name, stream).then(function() { 
    fs.unlink(file.path, function (err) { 
     if (err) { 
     console.log(err); 
     } 
    }); 
    res.redirect('/profile'); 
    }) 
}); 

module.exports = router;

Answer 1

此代碼應爲你工作。你需要記住的是： 1）你的文件對象的使用，而不是「名稱」 <「ORIGINALNAME」下使用唯一的水桶名 2） - 這個屬性不存在

app.post('/testupload', function(req, res){ 


    var file = req.files[0]; 

    console.log(file.path); 
    console.log(file.name); 

    console.log('FIRST TEST: ' + JSON.stringify(file)); 

    var stream = fs.createReadStream(file.path);  

    S3fsImpl.writeFile(file.originalname, stream).then(function() 
     { 
     console.log('File has been sent - OK'); 
     }, 
     function(reason) 
     { 
      throw reason; 
     } 
    ); 

    res.redirect('/index'); 

}); 

Answer 2

你可以試試這個代碼：

var S3fsImpl = new S3FS('bucket-name', { 
    region: 'us-east-1', 
    accessKeyId: 'XXXXXXXXXXXX', 
    secretAccessKey: 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX' 
}); 

var fsImplStyles = S3fsImpl.getPath(file.name); 

// Change us-east-1 for your region 
var url = 'https://s3-us-east-1.amazonaws.com/' + fsImplStyles; 

如果此代碼適用於您，請發送反饋意見。
