Question

我试图用jsonschema来验证我的json。这是我的server.js代码：

// set up ======================================================================
var express  = require('express');
var app      = express();                               // create our app w/ express
var port     = process.env.PORT || 8080;                // set the port
var bodyParser = require('body-parser');
var methodOverride = require('method-override')

app.use(function(req, res, next) {
    //the code hits this point!
    var data = '';
    req.on('data', function(chunk) {
        data += chunk;
    });
    req.on('end', function() {
        req.rawBody = data;

    });
    console.log(data);
    next();
});
app.use(bodyParser.json());
app.use(methodOverride());

// routes ======================================================================
require('./routes.js')(app);

// listen (start app with node server.js) ======================================
app.listen(port);
console.log("App listening on port " + port);

routes.js看起来像这样：

module.exports = function (app) {
    app.post('/api/postding',  function (req, res) {
            //do some schema validation
        var test=1;
    })
}

当我发布无效的json时，我现在收到此错误：

SyntaxError: Unexpected token t

                                <br> &nbsp; &nbsp;at process._tickCallback (node.js:419:13)

问题是我如何才能为我的postrequest执行jsonschema验证？

server.js

// set up ======================================================================
var express  = require('express');
var app      = express();                               // create our app w/ express
var port     = process.env.PORT || 8080;                // set the port
var bodyParser = require('body-parser');
var methodOverride = require('method-override')
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended: true}));

app.use(function(req, res, next) {
    //the code hits this point!
    var data = '';
    req.on('data', function(chunk) {
        data += chunk;
    });
    req.on('end', function() {
        req.rawBody = data;
        next();
    });
    console.log(data);
});
app.use(methodOverride());
// routes ======================================================================
require('./routes.js')(app);

// listen (start app with node server.js) ======================================
app.listen(port);
console.log("App listening on port " + port);

route.js

module.exports = function (app) {
    app.post('/api/postding',  function (req, res) {
        console.log(req.body);
        console.log(req.rawBody);
        res.send({"test":"data"});
    })
}

正在使用我的电脑

当我通过REST Client发布{＆＃34; name：＆＃34; hoer＆＃34;}时，控制台输出

App listening on port 8080

{}
{"name:"hoer"}

如何在node.js服务中调用POST方法？
