Question

嘿大家所以我有这个模板，我正在尝试从注册表单开始为它创建一个后端。虽然我的mongodb和我的应用程序之间存在某种类型的连接，但数据不会被发送到数据库，这是html：

    <ion-view class="auth-view" cache-view="false">
  <ion-nav-bar class="view-navigation">
    <ion-nav-back-button>
    </ion-nav-back-button>
  </ion-nav-bar>
  <ion-content class="padding">
    <div class="row form-heading">
      <div class="col">
        <h1 class="form-title">Create your account</h1>
        <h3 class="form-sub-title">Sign up with Social Network or Email</h3>
        <div class="social-sign-up button-bar">
          <a class="button icon ion-social-facebook button-positive"></a>
          <a class="button icon ion-social-twitter button-calm"></a>
        </div>
      </div>
    </div>
    <div class="row form-separator">
      <hr class="separator-line"/>
      <span class="separator-mark">OR</span>
      <hr class="separator-line"/>
    </div>
    <div class="row form-wrapper">
      <div class="col">
        <form name="signup_form" class="" novalidate>
          <div class="form-fields-outer list list-inset">
            <div class="row multi-inputs">
              <div class="col">
                <label class="item item-input">
                  <input class="multi-input" type="text" placeholder="Name" name="name" ng-model="user.name" required>
                </label>
              </div>
              <div class="col">
                <label class="item item-input">
                  <input class="multi-input" type="text" placeholder="Username" name="username" ng-model="user.userName" required>
                </label>
              </div>
            </div>
            <label class="item item-input">
              <input type="email" placeholder="Email" name="email" ng-model="user.email" required>
            </label>
            <label class="item item-input">
              <input type="tel" placeholder="Phone Number" name="phone" ng-model="user.phone" required>
            </label>
            <label class="item item-input" show-hide-container>
              <input type="password" placeholder="Password" name="password" ng-model="user.password" required show-hide-input>
            </label>
            <button type="submit" class="sign-up button button-block" ng-click="doSignUp()" ng-disabled="signup_form.$invalid">
              Sign Up
            </button>
            <p ng-show="error" class="message error">{{error}}</p>
          </div>
        </form>
      </div>
    </div>
  </ion-content>
</ion-view>

这是我试图发布数据的代码

.controller('CreateAccountCtrl',['$scope', '$http', function($scope, $http){
    $scope.doSignUp = function(){
        console.log("doing sign up");
    $http.post('/accounts', $scope.user).success(function (user) {
        console.log(user);
        });
//      $state.go('app.feed');
    };
}])

最后我的server.js到目前为止

var express = require('express');
var app = express();
var mongojs = require('mongojs');
var db = mongojs('accounts',['accounts']);
var bodyParser = require('body-parser');

//app.use(express.bodyParser());
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({
    extended: true
}));

app.use(express.static(__dirname + "/www"));
// app.get('/accounts', function(req, res){
// //    res.send("i got the request")

//     db.accounts.find(function(err, docs){
//        console.log(docs);
//        res.json(docs);
//    });

// });

app.post('/accounts', function(req, res){
//    console.log(req.body.user);
    db.accounts.insert(req.body.user, function(err, doc){
        res.json(doc);
    });
});


app.listen(3000);
console.log("server running on port 3000");

我知道有一些问题，但我只是不知道我还在学习什么。在此先感谢您的帮助

我也从mongo

遇到了这个错误

您的快递控制人员正在寻找身体中名为＆＃34; user＆＃34;的财产。您只是将用户对象直接传递到正文中。在角度控制器中，尝试以下操作：

.controller('CreateAccountCtrl',['$scope', '$http', function($scope, $http){
    $scope.doSignUp = function(){
        console.log("doing sign up");
    $http.post('/accounts', { user: $scope.user}).success(function (user) {
        console.log(user);
        });
//      $state.go('app.feed');
    };
}])

尝试通过angularjs和node将用户数据发送到mongodb
