主干同步返回一个空$ _POST数组 [英] Backbone Sync return an empty $_POST array

问题描述

我试图做我的第一个REST风格的应用程序与骨干网和Yii框架。
我曾与GET方法没有问题，但我用POST方法现在卡住了，创造了新的元素。

I'm trying to do my first RESTful app with Backbone and Yii Framework. I had no problem with the GET methods but I'm stuck now with the POST method, to create a new element.

我在骨干评论模型：

var commentModel = Backbone.Model.extend({

    urlRoot: "index.php/api/comments",
    idAttribute: 'id',

    defaults: {
        content: "Empty comment",
        status: 1
    }
});

在我看来，我添加了一个函数来创建一个新的评论从相对的形式传递值：

In my view I add a function to create a new Comment passing the values from the relative form:

on_submit: function(e) {
            var new_comment = new Comment({author_id: this.$('#author_text').val(), content: this.$('#content_text').val(), post_id: this.$("#post_text").val(), status: this.$("#status_text").val()});

         new_comment.save();
        },

展望与萤火虫似乎没事的要求，在POST选项卡中，我可以看到所有的值：

Looking the request with Firebug it seems all right, in the POST tab I can see all the values:

JSON            
author_id "7"   
content "Epic fail"
post_id "7" 
status "2"

Source 
{"content":"Epic fail","status":"2","author_id":"7","post_id":"7"}

但在我的PHP API的$ _POST变种是空的！

But in my php Api the $_POST var is empty!

foreach($_POST as $var=>$value) {

     if($model->hasAttribute($var))
        $model->$var = $value;
     else
        $this->_sendResponse(500);
}

任何人有一些想法？读Backbone.Sync的文档，我的理解，它应该使用POST用于创建请求。

Anyone has some ideas? Reading the documentation of Backbone.Sync I understand that it should use POST for create request.

我找到了一个解决方法从得到的值：

I found a workaround getting the values from:

file_get_contents('php://input') 

但ID感觉不对我...

but id doesn't feel right to me...

感谢。

推荐答案

Backbone.sync文档，

使用默认的实现，当Backbone.sync发送一个请求
  保存模式，其属性将被传递，序列化为JSON，
  而在HTTP正文中发送与内容类型的应用程序/ JSON。

With the default implementation, when Backbone.sync sends up a request to save a model, its attributes will be passed, serialized as JSON, and sent in the HTTP body with content-type application/json.

这意味着你不会在常规表格后，但在HTTP响应的主体接收参数，数据等。

which means you won't receive data in parameters like in a regular form post but in the body of the HTTP response.

您已经有了三个选项来处理这种行为：

You've got three options to deal with this behavior:

1. 修改服务器code，了解REST请求，请参阅Insert Backbone.js的模型导入MySQL数据库例如：


2. 查看是否 Backbone.emulateJSON 可以回答您的需求


3. Backbone.sync 并发送数据，以更好地满足您的服务器

1. Modify your server code to understand REST requests, see Insert Backbone.js model into MySQL database for example
2. See if Backbone.emulateJSON could answer your needs
3. Overwrite Backbone.sync and send the data to better fit your server
