json - Express.js : POST data as KEY of a req. body 对象而不是 req.body 的 VALUE？

Question

来 self 正在做的客户:

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

        }
    });

在服务器上(node.js/express.js)我在做:

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 的值是:

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

dataReceived 的值是:

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

这真的很奇怪，我找不到我做错了什么。有什么想法吗？

来自 BodyParser module documentation :

bodyParser.urlencoded(options)

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.

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？

在你的客户端移除 Stringify

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

        }
    });

或者在服务端重新解析

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