Question

我正在设计一个Web应用程序，后端系统是Express + Parse.Server。目前，我遇到了如何处理在Parse服务器中保存图片的问题。

这是我的ejs文件

<html>

    <head>      
            <title>test</title> 
    </head>
    <body>
    <form action='/pictest' method='post'>
        <h3>test</h3>

        <input type="file" name="pic" id ="pict" >
        <input type='submit' value='Submit'>    
        </form>
    </body>

</html>

这是server.js

router.post('/pictest',function(req,res){
    var pic = req.body.pic;
    console.log(pic);
    if (pic.length > 0) {

      var file = new Parse.File("photo.jpg", pic, "image/png");

       file.save().then(function() {
       console.log("file save success");
       res.end();
       }, function(error) {
       console.log("file save error " + error.message);
        });

    }
    res.send('test');
});

我得到的错误是：

TypeError: Cannot create a Parse.File with that data.

\JavascriftLinkParse\node_modules\parse\lib\node\ParseFile.js:131:15)

任何帮助都会有所帮助。谢谢！

您可以将multer与快递

一起使用

并在控制器

var buffer = req.files.pic[0].buffer;
var base64 = buffer.toString('base64');
var name = "pic_name";
var file = new Parse.File(name, { base64: base64 });
