index.php文件未收到由骨干邮政发送的JSON [英] index.php is not receiving the JSON sent by the backbone Post
问题描述
我一直在试图理解骨干是如何工作的，并与后端code通信，而我不能够接受我发送给我的PHP文件的JSON的一个问题。
I've been trying to understand how Backbone works and communicates with the back-end code, and I have an issue of not being able to receive the JSON I send to my php file.
下面是code：
HTML：
Here is the code: HTML:

body { padding: 0; margin: 0; background-color: #fff; }
h2 { font-family: Abel, sans-serif; margin: 0; padding: 0 0 5px 0;}
input { background-color: #ddd; border: 0; }
input:active { background-color: #bbb; }
#new-status { margin: 20px; padding: 20px; background-color: #67A9C3; }
#statuses { margin: 20px; padding: 20px; background-color: #92B456; }
</style>
</head>
<body>
<div id="new-status">
<h2>New monolog</h2>
<form>
<textarea id="status" name="status"></textarea>
<br />
<input type="submit" value="Post" />
</form>
</div>
<div id="statuses">
<h2>Monologs</h2>
<ul></ul>
</div>
<script src="js/jquery-min.js"></script>
<script src="js/underscore.js"></script>
<script src="js/backbone.js"></script>
<script src="js/main.js"></script>
</body>
</html>
JS：
var Status = Backbone.Model.extend({
url: 'api/index.php'
});
var Statuses = Backbone.Collection.extend({
model: Status
});
var NewStatusView = Backbone.View.extend({
events: {
"submit form": "addStatus"
},
initialize: function(options) {
this.collection.on("add", this.clearInput, this);
},
addStatus: function(e) {
e.preventDefault();
this.collection.create({ text: this.$('textarea').val() });
},
clearInput: function() {
this.$('textarea').val('');
}
});
var StatusesView = Backbone.View.extend({
initialize: function(options) {
this.collection.on("add", this.appendStatus, this);
},
appendStatus: function(status) {
this.$('ul').append('<li>' + status.escape("text") + '</li>');
}
});
$(document).ready(function() {
var statuses = new Statuses();
new NewStatusView({ el: $('#new-status'), collection: statuses });
new StatusesView({ el: $('#statuses'), collection: statuses });
});
的index.php：
index.php:
<?php
echo(var_dump($_POST));
?>
这是我所得到的回应：
阵列（0）{
}
array(0) { }
我已经打破我的头了这一点，所以请大家帮忙！
I've been breaking my head over this, so please HELP!
推荐答案
在计算器一些调查研究（真棒社区BTW），我能够发现主干不发直邮寄或获取到的RESTful API，或任何后code-背后可能，而是它是一个套头。所以，你必须拨开周围的$ _ SERVER全球，并找出所请求是什么。你可以找到在$ _ SERVER [REQUEST_METHOD]你的要求，不是执行一个开关/箱决定你想要这一要求做什么。这些数据正通过发送（骨干的情况下，始终是一个JSON字符串）是在HTTP正文中，并把它弄出来我用的file_get_contents（'PHP：//输入'）和德code中的JSON使PHP可以使用它。
After some more research on stackoverflow(awesome community btw) I was able to find that backbone does not send straight post or get to the RESTful api, or whatever the code-behind might be, but instead it is a set of headers. So you have to poke around the $_SERVER global and find out what is being requested. You'll be able to find your request in the $_SERVER["REQUEST_METHOD"], than perform a switch/case to decide what you want to do with that request. The data being sent through (in backbone's case is always a JSON string) is in the HTTP body and to get it out I used the file_get_contents('php://input'), and decode the JSON so that php can work with it.
<?php
$requestMethod = $_SERVER["REQUEST_METHOD"];
switch ($requestMethod)
{
case 'POST': $data = json_decode(file_get_contents('php://input'), true);
echo $data;
break;
}
?>
@orangewarp，我真的想了解发生了什么引擎盖下发生，而无需使用REST风格的PHP框架。
@orangewarp, I really wanted to understand what was happening under the hood without using a RESTful php framework.
