从PHP SoapServer返回PHP数组

问题描述

在创建服务端"方面，我对Soap来说还比较陌生，因此请事先为我想使用的任何术语提供应用程序.

I'm relatively new to Soap on the "creating the service side", so appologies in advance for any terminology I'm munging.

是否可以从使用PHP的SoapServer类设置的远程过程肥皂服务中返回PHP数组?

Is it possible to return a PHP array from a Remote Procedure Soap Service that's been setup using PHP's SoapServer Class?

我有一个WSDL(盲目地按照教程构建)，部分看起来像这样

I have a WSDL (built by blindly following a tutorial) that, in part, looks something like this

<message name='genericString'>
    <part name='Result' type='xsd:string'/>
</message>

<message name='genericObject'>
    <part name='Result' type='xsd:object'/>
</message>

<portType name='FtaPortType'>
    <operation name='query'>
        <input message='tns:genericString'/>
        <output message='tns:genericObject'/>
    </operation>
</portType>

我正在调用的PHP方法名为query，看起来像这样

The PHP method I'm calling is named query, and looks something like this

public function query($arg){
    $object = new stdClass();
    $object->testing = $arg;
    return $object;
}

这可以让我打电话

$client = new SoapClient("http://example.com/my.wsdl");
$result = $client->query('This is a test');

结果转储看起来像

object(stdClass)[2]
    public 'result' => string 'This is a test' (length=18)

我想从查询方法返回本地PHP数组/集合.如果我更改查询方法以返回数组

I want to return a native PHP array/collection from my query method. If I change my query method to return an array

public function query($arg) {
    $object = array('test','again');
    return $object;
}

它在客户端被序列化为一个对象.

It's serialized into an object on the client side.

object(stdClass)[2]
    public 'item' =>
        array
            0 => string 'test' (length=4)
            1 => string 'again' (length=5)

这很有意义，因为我在WSDL中将xsd:object指定为Result类型.如果可能的话，我想返回未包装在Object中的本机PHP数组.我的直觉说，有一个特定的xsd:type可以让我完成此操作，但我不知道.我还要解决被序列化为ArrayObject的对象.

This makes sense, as I've specific a xsd:object as the Result type in my WSDL. I'd like to, if possible, return an native PHP array that's not wrapped in an Object. My instincts say there's a specific xsd:type that will let me accomplish this, but I don't know. I'd also settle for the object being serialized as an ArrayObject.

不要在WSDL的技术细节上教育我.我正在尝试了解

Don't hold back on schooling me in the technical details os WSDL. I'm trying to get a grasp on the underlying concepts fo

推荐答案

我使用了此WSDL生成器来创建描述文件.

I used this WSDL generator to create description file.

返回字符串数组是我的Web服务所做的事情，这是WSDL的一部分:

Returning array of strings is something what my web service does, here's part of WSDL:

<wsdl:types>
<xsd:schema targetNamespace="http://schema.example.com">
  <xsd:complexType name="stringArray">
    <xsd:complexContent>
      <xsd:restriction base="SOAP-ENC:Array">
        <xsd:attribute ref="SOAP-ENC:arrayType" wsdl:arrayType="xsd:string[]" />
      </xsd:restriction>
    </xsd:complexContent>
  </xsd:complexType>
</xsd:schema>

</wsdl:types>
<message name="notifyRequest">
  <part name="parameters" type="xsd:string" />
</message>
<message name="notifyResponse">
  <part name="notifyReturn" type="tns:stringArray" />
</message>

然后定义API函数notify:

<wsdl:operation name="notify">
  <wsdl:input message="tns:notifyRequest" />
  <wsdl:output message="tns:notifyResponse" />
</wsdl:operation>
