Expressjs POST错误：类型错误：无法读取的不确定

Question

属性“名称”我是新来的NodeJS和expressJS，目前从expressJS，提示以下错误：

TypeError: Cannot read property 'name' of undefined

我expressJS代码如下：

app.configure(function(){ 

app.use(express.logger()); 

app.use(express.static(__dirname + '/app')); 

app.use(bodyParser.json()); 

app.engine('html',engines.underscore); 
/* 
Set views direcoctory. DO NOT set this with the static directory!. 
*/ 
app.set('views', __dirname+'/app/views'); 
app.set('view engine', 'html'); 

app.set('PORT',config.server.port); 
}); 

app.get("/", function(req,res){ 
res.render('index'); 
}); 

app.post("/webservice-1.0/rest/student/add/", function(req,res){ 
    console.log(req.param.student.name); 
    console.log(req.param.student.address); 
//res.render('index'); 
}); 

我在UI中使用angularJS来提交数据。我的angularJS控制器如下：

mainApp.controller("addStudentController", function($scope,$http) { 
var resData = {}; 
$scope.output = ""; 
var url = "/webservice-1.0/rest/student/add/"; 
$scope.addStudent = function(){ 
    $http.post(url, $scope.student) 
    .success(function(data, status, headers, config) { 
     resData = angular.fromJson(data); 
     $scope.output = "Student entered successfully with unique Id "+resData.id; 
    }).error(function(data, status, headers, config) { 
     resStatus = status; 
     $scope.output = "Something went wrong. Please try again later." 
    }); 
} 
});

这意味着没有req.param.student.name。要看到什么是从客户端来给服务器端，简单地做：

console.log(req.body)

你与请求主体，而不是PARAMS发送数据。

然后像req.body.data.name或req.body.data.student.name会起作用。
