jquery没有得到nginx 400错误请求的响应

Question

我正在运行本地VM进行开发。它使用php 5.4和nginx。我已经配置了nginx以允许交叉原始请求，因为我正在 backend.dev 开发laravel后端api，并在 frontend.dev 开发前端ember应用程序。

我遇到的问题是从我的后端返回400状态代码。其他状态代码工作得很好：201,404,304。出于某种原因，当我返回400时，jQuery只是取消。铬调试器只是说“已取消”，没有响应。

我硬编码了我的laravel后端，用这两个红色POST返回400。对于完全相同的端点的所有请求，都发布了完全相同的json主体。

class CompanyController extends \BaseController
{
    public function store()
    {
        $json = new stdClass;
        $json->code = 400;
        $json->message = 'Invalid data';

        return Response::json($json, $json->code);
    }
}

这是我的vhost的nginx conf文件

server {
  listen                *:80 ;

  server_name           backend.dev;
  access_log            /var/log/nginx/backend.dev.com.access.log;

  }

这是我的余烬控制器

App.PeopleNewController = Ember.ObjectController.extend({

    content: Ember.Object.create(),
    firstName: '',
    lastName: '',
    city: '',
    state: '',
    companyName: '',
    email: '',

    actions: {
        doneEditing: function () {

            var firstName = this.get('firstName');
            if (!firstName.trim()) {
                return;
            }

            var lastName = this.get('lastName');
            if (!lastName.trim()) {
                return;
            }

            var city = this.get('city');
            if (!city.trim()) {
                return;
            }

            var state = this.get('state');
            if (!state.trim()) {
                return;
            }

            var email = this.get('email');
            if (!email.trim()) {
                return;
            }

            // Create the new person model
            var person = this.store.createRecord('person', {
                firstName: firstName,
                lastName: lastName,
                city: city,
                state: state,
                email: email
            });

            // Clear the fields
            this.set('firstName', '');
            this.set('lastName', '');
            this.set('city', '');
            this.set('state', '');
            this.set('email', '');
            //this.set('companyName', '');

            // Save the new model
            person.save();
        }
    }
});

我在休息客户端得到的回复很好

我不知道造成这种情况的原因。我想用400状态代码获取json响应。
