express3 js req.body未定义 [英] express3 js req.body is undefined

问题描述

我在使用req.body时使用的是express2.js，我得不到定义或为空{}:

I am using express2.js when using req.body I get undefined or empty {}:

exports.post = function (req: express3.Request, res: express3.Response) {
    console.log(req.body);    
});

我有以下配置:

app.use(express.bodyParser());
app.use(app.router);

app.post('/getuser', routes.getuserprofile.post);

请求正文为XML，我检查了请求标头是否正确.

The request body is in XML and I checked the request header which was correct.

推荐答案

我错过了拥有XML的部分.我想req.body默认不会解析.

I missed the part where you had XML. I guess req.body doesn't parse by default.

如果您使用的是Express 2.x，则@DavidKrisch的此解决方案(复制到下面)

If you are using Express 2.x then perhaps this solution by @DavidKrisch is adequate (copied below)

// This script requires Express 2.4.2
// It echoes the xml body in the request to the response
//
// Run this script like so:
// curl -v -X POST -H 'Content-Type: application/xml' -d '<hello>world</hello>' http://localhost:3000
var express = require('express'),
    app = express.createServer();

express.bodyParser.parse['application/xml'] = function(data) {
    return data;
};

app.configure(function() {
    app.use(express.bodyParser());
});


app.post('/', function(req, res){
    res.contentType('application/xml');
    res.send(req.body, 200);
});

app.listen(3000);
