Nodejs-Req.body未定义在post 4.x [英] Nodejs- Req.body undefined in post with express 4.x

问题描述

我正在使用中间件 body-parser 来编码表单值以获取req.body对象。
但是当我调试我的代码，发现req.body是未定义的。这是我的代码

I am using a middleware body-parser to encoded the form values to get in req.body object. But as I debug my code, found out req.body is undefined. Here is my code

var express = require('express');
var app = express();
var bodyParser = require('body-parser');
app.use(bodyParser.urlencoded({ extended: false }));

收听发布请求

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

            //express attached the form encoded values into body
            var categoryName = req.body.categoryName;
        });

Html表单

<form action="/newCategory" role="form" method="post" class="form-inline">
    <input type="text" name="categoryName" placeholder="Category name" class="form-control" />
    <input type="submit" value="New Category" class="btn btn-primary" />
</form>

推荐答案

刚刚遇到同样的问题。看起来我解决了我的问题，移动我的代码映射路由之后的urlencoded行。我现在看到req.body的帖子。

Just ran into the same issue. It looks like I resolved my problem by moving my code to map routes after the urlencoded line. I am now seeing req.body in the post.

app.use(bodyParser.urlencoded({ extended: true }));


// Map routes
var controllers = require("./controllers");
controllers.init(app);
