如何在CURL请求中为XPLAN API构建edai.Search方法的第三个参数？

mic*_*usa 6 php xml curl

我试图在API上运行搜索,该API要求我的查询数据被设置为嵌套在XML请求中的XML.我将发布我的整个课程和方法调用(我发送给iress技术支持),以便可以对其进行全面审核,并且在任何人都无法访问相同API的情况下,他们可以立即为自己重现问题.

class XMLCurler
{
    private $username = '[redacted]';
    private $password = '[redacted]';
    private $url = 'https://[redacted].xplan.iress.com.au/RPC2/';
    public $ch;     // the curl handle
    public $token;  
    public $results;

    public function __construct() {
        if ($this->connect()) {
            if ($this->login()) {
                echo "<div class=\"success\">Successful Connection & Login. Token: {$this->token}</div>";
            }
        }
    }

    public function __destruct() {
        if ($this->ch) {
            $this->disconnect();
        }
    }

    public function connect() {
        if (!$this->ch = curl_init($this->url)) { // generate curl handle
            echo "<div class=\"error\">CURL Error While Connecting (check url)";
            return false;
        }
        return true;
    }

    public function disconnect() {
        curl_close($this->ch);
    }

            return false;
        }
        $decoded = xmlrpc_decode($response);
        if (is_array($decoded) && xmlrpc_is_fault($decoded)) {
            echo "<div class=\"error\">Error Response: {$decoded['faultString']} ({$decoded['faultCode']})</div>";
            return false;
        }
        return $decoded;    
    }

以下是我打电话的方式. edai.ListChildren因为我不必发送任何XML数据. edai.Search不起作用,因为我无法在XML请求中正确准备XML查询.

$XC = new XMLCurler();

/* edai.ListChildren works as desired/expected */
$path = "/entitymgr/client";
if ($XC->listChildren($path)) {
    echo "<div>List of Children Successful.<pre>";
    var_export($XC->results);
    echo "</pre></div>";
}

/* edai.Search does not work */
$basepath = "entitymgr/client";
$queryxml = <<<XML
<EntitySearch>
 <SearchResult field="first_name"/>
 <SearchResult field="last_name"/>
 <SearchQuick><s>last_name:Smith</s></SearchQuick>
</EntitySearch>
XML;
if ($XC->search($basepath, $queryxml)) {
    echo "<div>Search Successful.<pre>";
    var_export($XC->results);
    echo "</pre></div>";
}

这是尝试的请求和错误消息.

我几周前联系了iress.com,他们叫我松散地确认我有权访问API,并告诉我他们会联系 - 跟进电话没有发生我会喜欢回到这个项目的工作.

我确实知道有一个Smith匹配我的查询的姓氏.

我没有Python经验,所以错误响应对我没有帮助.我做了比我发布的更多的冰雹尝试,但我厌倦了浪费我的时间.我不知道,如果第三个参数,就是要嵌套的内部<value>,<param>,<struct>,<string>,<array>,<xml>,或别的东西完全.

如果有人对如何为请求准备XML查询有任何建议,我将运行它们并提供反馈.

我也很高兴收到关于类设计,安全性问题以及完全不同的php方法的建议,以获得edai.Search返回一些有用的数据.

根据@ThW的要求,以下是xml尝试的集合及其各自的错误响应:https://pastebin.com/dYtwXWxz
