Question

以下是我的代码相对于问题： server.js文件：

app.post('/user', function(req,res){
    console.log(req.body);
    var user = mongoose.Schema('User',req.body);
    user.save(function(err,user){
        if(err) console.log(err);
        console.log("Successfully added user to MongoDB");
    });
    res.sendStatus(200);
});

角度控制器：

app.controller('RegisterController',['$scope','$http',function($scope,$http){
    $scope.submitData = function(user){
        var dob = user.dob.day.toString()+"/"+user.dob.month.toString()+"/"+user.dob.year.toString();
        user.dob = dob;
        var post = $http.post('/user', user);
        post.success(function(data,status,headers,config){
                console.log(data);
                console.log(status);
                console.log('Success!');
            });  
    }
    $scope.countTo= function(count){
        var array = [];
        for(i = 1; i<=count; i++){
            array.push(i);
        }
        return array;
    }
    $scope.countFrom = function(startingPoint,count){
        var numbers = [];
        for(i=startingPoint; i>startingPoint-count;i--){
            numbers.push(i);
        }
        return numbers;
    }
}

Mongoose Schema：

    var mongoose = require('mongoose');

var userSchema = mongoose.Schema({
    email: { 
        type:String,
        required: true
    },
    dob: {
        type: String,
        required: true
    },
    password: {
        type:String,
        required:true
    },
    postcode: {
        type:String,
        required:true
    },
    address: {
        type:String,
        required:true
    }
});

var User = mongoose.model('User',userSchema);

这是错误：

看起来你在做Mongoose方面的事情有点不对劲。不是100％确定这是导致错误的原因，但它仍然存在问题。

var user = mongoose.Schema('User',req.body);

这不是你认为它做的事情。 Schema期望将表示Schema的对象作为第一个参数，例如{email：String，dob：String}。传递字符串＆＃39; User＆＃39;这里行不通。

相反，您想要引用您已定义的模型。您可以通过

完成此操作

导出并随后将您的用户模型包括为var User = require('UserModel.js')
或直接引用Mongoose中的模型（假设它在您调用之前在应用程序中定义），如var User = mongoose.model('User);

一旦有了Model对象的引用，就可以初始化一个新文档。在您的情况下，您可能希望您的代码读取类似

的内容

var user = new User(req.body); user.save(function(err,user){...}

尝试，然后告诉我们您是否仍然看到该错误。
