Question

尝试从MEAN应用程序中的注册表单发布，我可以使用Postman成功发布使用x-www-form-urlencoded，但是当我在console.log中时，应用程序中的请求主体是空的。登记表（部分）：

 AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);

                // make a list to hold state of every color
                for (int i = 0; i < colors.length; i++) {
                    ColorVO colorVO = new ColorVO();
                    colorVO.setName(colors[i]);
                    colorVO.setSelected(checkedColors[i]);
                    colorList.add(colorVO);
                }

                // Do something here to pass only arraylist on this both arrays ('colors' & 'checkedColors')
                builder.setMultiChoiceItems(colors, checkedColors, new DialogInterface.OnMultiChoiceClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which, boolean isChecked) {
                        // set state to vo in list
                        colorList.get(which).setSelected(isChecked);
                        Toast.makeText(getApplicationContext(),
                                colorList.get(which).getName() + " " + isChecked, Toast.LENGTH_SHORT).show();
                    }
                });

                builder.setCancelable(false);

                builder.setTitle("Your preferred colors?");

                builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        txtSelected.setText("Your preferred colors..... \n");

                        // save state of selected vos
                        ArrayList<ColorVO> selectedList = new ArrayList<>();
                        for (int i = 0; i < colorList.size(); i++) {
                            ColorVO colorVO = colorList.get(i);
                            colors[i] = colorVO.getName();
                            checkedColors[i] = colorVO.isSelected();
                            if (colorVO.isSelected()) {
                                selectedList.add(colorVO);
                            }
                        }

                        for (int i = 0; i < selectedList.size(); i++) {
                            // if element is last then not attach comma or attach it
                            if (i != selectedList.size() - 1)
                                txtSelected.setText(txtSelected.getText() + selectedList.get(i).getName() + " ,");
                            else
                                txtSelected.setText(txtSelected.getText() + selectedList.get(i).getName());
                        }
                        colorList.clear();
                    }
                });

                builder.setNegativeButton("No", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        // make sure to clear list that duplication dont formed here
                        colorList.clear();
                    }
                });

                builder.setNeutralButton("Cancel", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        // make sure to clear list that duplication dont formed here
                        colorList.clear();
                    }
                });

                AlertDialog dialog = builder.create();
                dialog.show();

api.js（部分）

<form class="form-horizontal" ng-submit="register.saveUser()">

            <div class="form-group">
                <label class="col-sm-2 control-label">Name</label>
                <div class="col-sm-6">
                    <input type="text" class="form-control" ng-model="user.userData.name">

在调用api.js之前，我在server.js中有app.use bodyParser

server.js（part）

var bodyParser = require('body-parser');    // get body-parser
var User       = require('../models/user');
var jwt        = require('jsonwebtoken');
var config     = require('../../config');


var superSecret = config.secret;

module.exports = function(app, express) {

    var apiRouter = express.Router();

    apiRouter.post('/register', function(req, res) {

            var user = new User();  
            user.name = req.body.name;  
            user.username = req.body.username; 
            user.password = req.body.password; 

            console.log(req.body); //EMPTY

我做错了什么但却看不清楚。

为@mscdex添加： register.saveUser（）引用userRegisterController saveUser（）函数：

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

var apiRoutes = require('./app/routes/api')(app, express);
app.use('/api', apiRoutes);

这使用userService注册函数：

.controller('userRegisterController', function(User) {

    var vm = this;

    // function to create a user
    vm.saveUser = function() {
        vm.processing = true;
        vm.message = '';

        // use the register function in the userService
        User.register(vm.userData)
            .success(function(data) {
                vm.processing = false;
                vm.userData = {};
                vm.message = data.message;
            });

    };

这会调用我上面发布的api文件。

当我使用Postman时，console.dir（req.headers ['content-type']）显示'application / x-www-form-urlencoded'并且成功。

我今天花了几个小时来完成这个问题，并最终解决了未定义的问题。被apiRouter功能接收是由于我使用了

<input type="text" class="form-control" ng-model="user.userData.name">

而我应该使用

<input type="text" class="form-control" ng-model="register.userData.name">

因为我用过

.when('/register', {
            templateUrl: 'app/views/pages/register.html',
            controller: 'userCreateController',
            controllerAs: 'register'
        });

apiRoutes文件中的

。在这种情况下，我仍然在学习ControllerAs的使用。

Node.js request.body是空的
