Question

我想知道为什么这不起作用，我有一个AngularJS应用程序通过AJAX数据发送到Symfony2应用程序。如您所见，数据在我的网络控制台中发送

<?php

namespace Supbox\CloudBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\JsonResponse;
class FolderController extends Controller
{
    public function createAction(){
        $post = $this->getRequest()->request;
        $name = $post->get("name");
        $folder = $post->get("folder");
        var_dump($post);
        die; 
    }
}

AngularJS代码

    $http({
            method: 'POST', 
            url: route.folder.create, 
            data: {
                folder: $scope.id,
                name: name
            }
        })

Opera网络控制台输出

Answer 1

如果您（Angular JS）通过标头将数据发布为JSON，则需要更改您的代码：

public function createAction(){
    $post = $this->getRequest()->getContent();
    $post = json_decode($post);
    $name = $post->name;
    $folder = $post->folder;
    var_dump($post);
    var_dump($name); // null
    var_dump($folder); // null
    die; 
}

Answer 2

不知道为什么，Angular $ http将数据作为请求体发送，JSON编码，而Symfony2正在读取$ _GET和$ _POST数组。

所以你有2个解决方案：

1-更新Php代码，您可以覆盖SF2请求类（https://gist.github.com/ebuildy/fe1e708e466dc13dd736）

2-更新Js代码，您可以“转换”$ http请求（https://gist.github.com/bennadel/11212050）
