Node.js 在NodeJS中使用Multer时出现意外字段错误

错误：

Error: Unexpected field

我在前端使用KendoUI文件上载：

                        <form id="forFile" action="/postFile" method="POST" enctype="multipart/form-data">
                            <div class="form-group">
                                <label for="inputFile">Upload Attachments</label>
                                <div class="col-sm-offset-2 col-sm-10 pull-right">
                                    <input type="file" id="inputFile" name="inputFile">
                                </div>
                            </div>
                        </form>

我知道这几乎是关于堆栈溢出的几个问题的重复，但所有这些问题的答案都是使name属性与upload.array或upload.single参数相匹配（我已经尝试了这两个参数），这在我的代码中是令人满意的，正如您可以从捕获我的上载的路由中看到的：

var multer = require("multer");
var upload = multer({ dest: "upload/" });
var type = upload.array('inputFile', 1); //KendoUI

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


var tmp_path = req.file.path;

  /** The original name of the uploaded file
      stored in the variable "originalname". **/
  var target_path = 'uploads/' + req.file.originalname;

  /** A better way to copy the uploaded file. **/
  var src = fs.createReadStream(tmp_path);
  var dest = fs.createWriteStream(target_path);
  src.pipe(dest);
  src.on('end', function() { res.render('complete'); });
  src.on('error', function(err) { res.render('error'); });


  sendJsonResponse(res, 200, "you posted a file");
});

$("#inputFile").kendoUpload({
        multiple: false,
        async: {
            saveUrl: "postFile",
            removeUrl: "removeFile",
            autoUpload : true
        },
        complete: onComplete
    });

var multer = require("multer");
var upload = multer({ dest: "upload/" });
var type = upload.array('inputFile', 1); //KendoUI

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


var tmp_path = req.file.path;

  /** The original name of the uploaded file
      stored in the variable "originalname". **/
  var target_path = 'uploads/' + req.file.originalname;

  /** A better way to copy the uploaded file. **/
  var src = fs.createReadStream(tmp_path);
  var dest = fs.createWriteStream(target_path);
  src.pipe(dest);
  src.on('end', function() { res.render('complete'); });
  src.on('error', function(err) { res.render('error'); });


  sendJsonResponse(res, 200, "you posted a file");
});
