Question

我是node.js / express的新手，我有一个问题。我正在搜索这几个小时。

我正在尝试为我的基本博客创建一个管理面板，我需要发布POST：

title＆amp;来自HTML输入的content 到我的panel.js

以下是我的尝试：

从HTML页面发布数据，它有效：

$(document).ready(function() {
    $('#but').click(function(e) {
      e.preventDefault();
     var title = document.getElementById('title');
      $.ajax({
          type: "POST",
          url: "/panel/save",
          data: title.value,
          dataType: "json"
    });


    });
  });

panel.js

var express = require('express');
var router = express.Router();
var app = express();


router.get('/', function(req, res) {
res.render('panel_html');

});

/* mysql things */

router.get('/save/', function(req, res) {
   var t = req.params.title;
    console.log("title :"+t);
});

module.exports = router;

首先，确保在将title变量放入ajax调用时将其命名为对象文字，从而将其命名为<{1}}变量：

$.ajax({
  type: "POST",
  url: "/panel/save",
  data: { title: title.value },
  dataType: "json"
});

接下来，将您的router.get更改为router.post，以便它可以接受该路线。接下来，您应该通过req.body访问您的postdata。在此路线声明之前，请确保您在应用中的某个地方use router.post('/save/', function(req, res) { var t = req.body.title; console.log("title :"+t); }); {{1}} {/ 3}}。

{{1}}

从HTML页面获取POST数据到Node.Js / Express？
