在nodejs中使用Multipart上传文件失败

Question

我正在尝试使用 multipart 在节点 js 中上传文件，但出现无法 POST 错误？我是节点 js 的新手。所以你能帮我解决我做错的事吗我的代码？ HTML

<form id   = "uploadForm"
     enctype   = "multipart/form-data"
     action    = "/api/uploadfile"
     method    = "post">
<input type="file" name="fileUpload"/>
<input type="submit" value="Upload File" name="submit">
</form>

Server.js

var express  = require('express');
var app      = express();
var multer  =   require('multer');
app.use(express.static(__dirname));
app.get('/', function(request, response){
    response.sendFile("./index.html"); 
});

var storage =   multer.diskStorage({
  destination: function (req, file, callback) {
    callback(null, './uploads');
  },
  filename: function (req, file, callback) {
    callback(null, file.fieldname + '-' + Date.now());
  }
});
var upload = multer({ storage : storage}).single('fileUpload');


app.post('/api/uploadfile',function(req,res){
    upload(req,res,function(err) {
        if(err) {
            return res.end("Error uploading file.");
        }
        res.end("File is uploaded");
    });
});


app.listen(8080);
console.log("App listening on port 8080");

报错信息如下：

Error uploading file

Answer 1

我试过你的代码，它的工作 here.The 原因可能是，

1)你错过了表单标签的关闭

<html>
<form id       =  "uploadForm"
     enctype   =  "multipart/form-data"
     action    =  "/api/uploadfile"
     method    =  "post"
>
<input type="file" name="fileupload"  /> 
<input type="submit" value="Upload file" name="submit">
</form>
</html>

2) 确保您有一个名为 -> uploads

的文件夹
