如何上传使用节点的js文件？(How do I upload a file using node j

我环顾四周，看着就如何上传使用节点/快递文件的各种教程。我觉得我做错了什么对HTML或JQuery的一面。我使用下面的链接作为http://howtonode.org/really-simple-file-uploads 。

但是我得到的错误：

TypeError: Cannot read property 'fileUpload' of undefined    at module.exports.fileCreate

这里是我下面的代码：

uploadcontroller.js

fs.readFile(req.files.fileUpload.path, function (err, data) {
    var newPath = __dirname + "/uploads/" + imgString;
    fs.writeFile(newPath, data, function (err) {
    });
});

HTML片段

<div class="form-group">
    <label for="fileUpload">Upload File</label>
    <input type="file" name="fileUpload" id="fileUpload">
</div>

我现在用的帆框架（不知道如果让区别）

编辑：填写表格

<form role="form" class="uploadFileForm">
    <div class="form-group">
        <label for="fileTitleInput">Title</label>
        <input type="text" name="formTitleInput" id="formTitleInput">
    </div>
    <div class="form-group">
        <label for="fileDescriptionInput">Description</label>
        <textarea class="form-control" rows="4" id="fileDescriptionInput"></textarea>
    </div>
<div class="form-group">
        <label for="fileUpload">Upload File</label>
        <input type="file" name="fileUpload" id="fileUpload">
    </div>
    <button type="submit" class="btn btn-default" id="file-submit-btn">Publish to Web</button>
</form>

Answer 1:

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

    fs.readFile(req.files.image.path, function (err, data) {

        var imageName = req.files.image.name

        /// If there's an error
        if(!imageName){

            console.log("There was an error")
            res.redirect("/");
            res.end();

        } else {

          var newPath = __dirname + "/uploads/fullsize/" + imageName;

          /// write file to uploads/fullsize folder
          fs.writeFile(newPath, data, function (err) {

            /// let's see it
            res.redirect("/uploads/fullsize/" + imageName);

          });
        }
    });
});

Answer 2:

app.post('/', function(req, res) {
  console.log(req.files);
  fs.readFile(req.files.displayImage.path, function (err, data) {

    var newPath = __dirname + "/uploads/"+req.files.displayImage.name;
    fs.writeFile(newPath, data, function (err) {
      if (err) throw err;
      res.redirect("back");
    });
  });
});

仅供参考，“执行console.log（req.files）”将包含这样的事情：
