使用SoapHeader实现Soap请求验证

在PHP的Soap Extension中, 对于SoapServer来说, 并没有方法可用得到/处理客户端发送的SoapHeader信息.
网上也有很多人认为, 只能通过读取POST过来的请求XML文件, 分析, 才能得到客户端发送过来的SoapHeader.
但, 其实在SoapServer端, 其实是有一种办法, 可用把SoapHeader当作一个请求来处理, 从而获取到客户端提交的SoapHeader信息.
假设客户端代码如下:

<?php
/*
 * 保存用户名和密码的载体
 */
class SoapUserInfo {
    /**
	 * @var char $name
	 */
    public $name;
    /**
	 * @var char $password
	 */
    public $password;
    public function __construct($l, $p) {
        $this->Password = $p;
        $this->Username = $l;
    }
}
?>

然后客户端生成SoapHeader

<?php
    $soap_header = new SoapHeader("http://www.laruence.com", 'Authorise'
			, new SoapUserInfo('laruence', 'password'), false, SOAP_ACTOR_NEXT);
?>

也许细心的同学会注意到第4个参数FALSE第5个参数SOAP_ACTOR_NEXT, 这是什么呢? 我最后再讲.
然后, 创建客户端, 绑定SoapHeader

<?php
    $client = new SoapClient($wsdl);
    $client->__setSoapHeaders(array($soap_header));
    $client->__soapCall('request', array());
?>

现在, 客户端已经发起了请求, 请求中也包含了SoapHeader, 其中有了我们验证需要的用户名/密码信息.
那么, 在服务端, 该如何做呢?

<?php
$server = new SoapServer('laruence.wsdl');
$server->setClass('InterfaceClass');
$server->handle();
?>

关键的地方就在, 服务端接收请求以后, 会实例化一个处理类, 然后分析SoapHeader, 接着就会调用InterfaceClass::Authorise这个方法(Authorise是我们请求头中的变量名), 所以, 我们就可用在InterfaceClass类中, 定义个Authorise方法, 并在这个方法中对SoapHeader中的信息做验证.
然后, 请求体(Soap body)中的方法被调用, 因为不论Authorise方法返回什么(除非exit), 请求体中的方法一定会被调用, 所以要寻找个变量记录验证的结果.

<?php
class InterfaceClass {
	/**
	 * @var bool $authorized
     */
    private $authorized = FALSE;
    /*
     * Authentication function
     *
     * @param string username
     * @param string password
     */
    public function Authentication($username, $password) {
		$this->authorized = validateUser($username, $password);
    }
    /*
     * Test method
     */
    public function request(){
		if ($this->authorized) {
			//验证成功, 继续处理.
		} else {
			//验证失败, 拒绝请求.
		}
    }
}
?>

当然, 对于网上说的另外一种方法, 通过分析请求的XML文件, 也可以:

<?php
class InterfaceClass {
	/**
	 * @var bool $authorized
     */
    private $authorized = FALSE;
    function __construct() {
         $xml = file_get_contents('php://input');
         //分析xml, 获得SoapHeader数据, 验证
    }
}
?>

Must Understand

这个参数指明了, 是否服务端必须要了解SoapHeader, 如果这个参数为真, 而服务端并不能识别响应的Header, 则会引发一个Soap Fault(Header not understood).

SOAP_ACTOR_NEXT

actor指明了SoapHeader要传递给谁, 被谁处理.
SOAP_ACTOR_NEXT的意思就是, 下一个接受到这个请求头的Service, 在本文的例子中只有一个Server,当然也就没有关系了.
在SoapServer的构造函数中, 我们可以指明一个Server的Actor, 比如:

<?php
$server = new SoapServer($wsdl, array('actor' => 'laruence'));
?>

这样, 我们就可以在Client的SoapHeader中, 通过设置actor是laruence, 来让指定的Server来获得我们设置的头部的信息.

    想问一下,客户端的SoapHeader中请求的Authorise这个变量对应的是服务端的一个验证方法,如果这个方法我在wsdl文档中不提现,服务端有,那么服务端能获取header过来的验证数据吗? 我在wsdl文件中定义了Authorise的情况下是可以取到验证数据的,但是不定义的情况下就不行了。

    //认证
    $h = new SoapHeader(‘urn:oufei’, ‘auth’, ‘123456’, false, SOAP_ACTOR_NEXT);
    $result = $soapClient-> __setSoapHeaders( array($h) );
    一直没调用auth方法
    function auth($a){
    if($a != ‘123456789’){
    throw new SoapFault(‘server’, “认证失败!”);
    }
    }
