将AMF类型的对象从flex转换回PHP [英] AMF typed objects from flex back to PHP

问题描述

昨天，按照此问题。

我现在面临的问题是我想将类型对象从flex发送到PHP，在PHP方面，可以将其作为类型对象而不是 stdClass 。

The problem I am facing now is that I would like to send a typed object from flex to PHP and on the PHP side, be able to recieve it as a typed object instead of stdClass.

这里是类在flex中：

Here is the class in flex:

package com.mysite
{
    [Bindable]
    [RemoteClass(alias="CTest")]
    public class CTest
    {

        public var stuff1:String;

        public var stuff2:String;

        public function CTest()
        {
        }
    }
}

这是PHP中的相应类：

And this is the corresponding class in PHP:

<?php
namespace modules\testing;

class CTest{

    var $_explicitType = 'CTest';

    var $stuff1;

    var $stuff2;
}

在flex中，我像这样发送对象：

In flex, I am sending the object like so:

var remoteObject:RemoteObject = new RemoteObject(); 
remoteObject.endpoint = "http://localhost/to/my/amf/endpoint"; 
remoteObject.showBusyCursor = true; 
remoteObject.source = 'testing'; 
var op:AbstractOperation = remoteObject.getOperation(null); 
op.addEventListener(ResultEvent.RESULT, result); 
op.send( new CTest()); 

在PHP方面，对象被检索到名为 $ parameters的变量中。然后，在其上使用print_r将结果写入文件：

On the PHP side, the object is retrieved into a variable called $parameters. I then use print_r on it to write the result to a file:

$z = print_r($parameters, true);
$s = fopen('D:\test.txt', 'w+');
fwrite($s, $z);
fclose($s);

可以看出，返回的结果是未键入的，并且是 stdClass 对象：]

And as can be seen, the result comes back untyped and is a stdClass object:]

Array
(
    [0] => stdClass Object
        (
            [stuff1] => 
            [stuff2] => 
        )

)

经过一些测试，我从PHP对象中删除了命名空间，并将其移到了全局命名空间中。这似乎已经解决了问题。我尝试将 RemoteClass 设置为 \modules\testing\CTest 以及 modules .testing.CTest 。然后将两个测试的 $ _ eplicitType 设置为相同的值。

After some testing, I removed the namespace from the PHP object and moved it into the global namespace. This seems to have resolved the issue. I have tried setting RemoteClass to \modules\testing\CTest and also modules.testing.CTest. $_eplicitType was then set to the same value for both tests.

结果是当我使用 modules.testing.CTest ，这是Zend_AMF看到的类名。如果我使用命名空间符号，则Zend_AMF会看到 modulestestingCTest ，因为所有的斜杠都被去除了。

The result is that when I use modules.testing.CTest, this is the classname that Zend_AMF sees. If I use namespace notation, Zend_AMF sees modulestestingCTest, as all the slashes get stripped out.

但是我怎么办

推荐答案

最终解决了该问题。这是为将来可能遇到相同问题的人提供的解决方案。

Finally resolved the issue. Here is the solution for those who might come across the same issue in the future.

对于您的PHP类：

<?php
namespace app\testing;
class CTest{

    var $_explicitType = 'app\testing\CTest';

    var $stuff1;

    var $stuff2;
}

对于您的动作脚本类：

package com.mysite
{
    [Bindable]
    [RemoteClass(alias="app\\\\testing\\\\CTest")]
    public class CTest
    {

        public var stuff1:String;

        public var stuff2:String;

        public function CTest()
        {
        }
    }
}

我认为问题是由于AMF主体的序列化和反序列化引起的。实际上，远程类有2个斜杠转义了，结果是： app\\testing\\CTest 。一旦它被Zend_AMF反序列化，由于有2个斜杠，这意味着反斜杠被转义为： app\testing\CTest 。当然，这只是预感，但是与Charles进行的一些测试证明确实是这种情况。

I think the problem is due to the serialization and deserialization of the AMF body. Effectively, the remote class is has 2 slashes escaped, resulting in this: app\\testing\\CTest. Once it is deserialzed by Zend_AMF, since there are 2 slashes, it means that the backslashes are escaped into this: app\testing\CTest. This is just a hunch of course, but some testing with Charles proved that this is the case.

另一种可能的解决方案是修改 Zend_Amf_Parse_TypeLoader.php 。在第99行，我们可以替换：

Another possible solution is to modify Zend_Amf_Parse_TypeLoader.php. On line 99, we could replace:

 if(!$class) {
            $class = str_replace('.', '_', $className);
  }

with

if(!$class) {
     $class = str_replace('.', '\\', $className);
}

有效地，我们可以将点语法用于类映射，这是有效的会很好地放置在：

Effectively, we can then just use dot syntax for the class mappings, which actionscript will place nicely with:

[RemoteClass(alias="app.testing.CTest")]

var $_explicitType = 'app.testing.CTest';

显然，这是一个很好的解决方案，但我不希望使用供应商代码进行修改，因为Zend_AMF库将来会更新为新版本。现在，我的解决方案是只使用4个斜杠。

Obviously this will is a pretty nice solution, but I prefer not to modify with vendor code, as the Zend_AMF library will be updated with newer versions in the future. For now, my solution is to just use 4 slashes.
