Express.js:将数据作为req.body对象的KEY而不是req.body的VALUE进行发布吗? [英] Express.js : POST data as KEY of a req.body object instead of VALUE of req.body?

问题描述

我正在做的客户:

$.ajax({
        url: '/create',
        type: 'POST',
        data: JSON.stringify({
            theme: "somevalue",
            snippet: {
                name: "somename",
                content: "somevalue"
            }
        }), 
        complete: function (response)
        {

        }
    });

在服务器(node.js/express.js)上我正在做

on the server ( node.js/express.js ) I'm doing :

var app = express();
app.use(cookieParser());
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended: true}));
.......
... 
app.post('/create', function (req, res)
{
   var dataReceived = req.body;
});

我希望dataReceived的值为:

{
   "theme" : "somevalue",
   "snippet" : {
     "name": "somename",
     "content" : "somevalue"
   } 
}

dataReceived的值为:

{ 
 '{"theme":"somevalue","snippet":"name":"somename","content":"somevalue"}}': '' 
}

这真的很奇怪，我找不到我做错的事情.有什么想法吗?

This is really weird and I can't find what I'm doing wrong. Any ideas?

来自 BodyParser模块文档:

bodyParser.urlencoded(options)

bodyParser.urlencoded(options)

返回仅解析经过urlencoded主体的中间件.这个解析器 仅接受主体的UTF-8编码并支持自动 gzip压缩和deflate编码.

Returns middleware that only parses urlencoded bodies. This parser accepts only UTF-8 encoding of the body and supports automatic inflation of gzip and deflate encodings.

将包含已解析数据的新主体对象填充到 中间件(即主体)之后的请求对象.该对象将 包含键值对，其中值可以是字符串或数组 (当extended为false时)或任何类型(当extended为true时).

A new body object containing the parsed data is populated on the request object after the middleware (i.e. req.body). This object will contain key-value pairs, where the value can be a string or array (when extended is false), or any type (when extended is true).

这与我的问题有关吗?

推荐答案

在客户端删除Stringify

Remove Stringify in your client side

$.ajax({
        url: '/create',
        type: 'POST',
        data: {
            theme: "somevalue",
            snippet: {
                name: "somename",
                content: "somevalue"
            }
        }, 
        complete: function (response)
        {

        }
    });

或在服务器端再次解析

app.post('/create', function (req, res)
{
   var dataReceived = JSON.parse(req.body);
});
