文件上傳
multer模塊官網

• html頁面

<form method="post" enctype="multipart/form-data" class="uploadFile" action="lalocal-sales/customers/excel">
       <button class="btn btn-success btn-file-up"><input type="file" name="file" class="file_up" id='file'>上傳文件</button>
 </form>

• js代碼

$('.file_up').change(function() {
    $('.uploadFile').submit();
});

• node層
  先引入multer模塊，設置文件上傳目錄

var multer = require('multer');
var upload = multer({
    dest: './upload/'
});

再對上傳的文件進行格式化

router.post("/customers/excel",upload.single('file'),function(req,res,next) {
    var url = global.baseURL+req.url;
  console.log('url................................'+url);
  console.log('請求路徑.....'+req.url);
    var obj = req.file;
    var tmp_path = obj.path;
    var new_path = "upload/excelfile.XLSX";
    console.log("原路徑：" + tmp_path);
    /*修改上傳文件地址*/
    fs.rename(tmp_path, new_path, function(err) {
            if (err) {
                    throw err;
            }
    });

最后上傳到服務器

superagent
                 .post(url)
        .attach('file', new_path)
        .end(function(err1, res1) {
        if (res1.ok) {
                    console.log(JSON.stringify(res1.body));
                    fs.unlinkSync(new_path);//刪除 
                    res.redirect(global.rootUrl+'custom');
                    }
            });
