PHP中带有POST和XML的REST API在不应该返回false的时候返回false

所以这个API的制造者把我的代码清楚地标记为功能性的，因为他们做了这个该死的东西。问题是，只要我单独使用PI或QS, REST API就可以正常工作。当我尝试使用更高级的特性时，需要与REST请求一起发送XML文档，它在执行时只返回false。

<?php
$objCurlToken = curl_init();
$strUrlToken = "https://servername/apimember/services/rest/connect/open/username/password/token";
$arrCurlOptions1 = array(
    CURLOPT_URL => $strUrlToken,
    CURLOPT_RETURNTRANSFER => true
);
curl_setopt_array($objCurlToken, $arrCurlOptions1);
$strXMLToken = curl_exec($objCurlToken);
$objXML = simplexml_load_string($strXMLToken);
curl_close($objCurlToken);

$strXMLPost = '
<?xml version="1.0" encoding="utf-8"?>
<synchroMember>
    <memberUID>
        EMAIL
    </memberUID>
    <dynContent>
        <entry>
            <key>
                EMAIL
            </key>
            <value>

        </entry>
        <entry>
            <key>
                FIRSTNAME
            </key>
            <value>
                KLAUS LAGER
            </value>
        </entry>
        <entry>
            <key>
                EMVADMIN1
            </key>
            <value>
                This is klaus lager, the test subject
            </value>
        </entry>
    </dynContent>
</synchroMember>
';
$objCurlProbe = curl_init();
$strUrlProbe = "https://servername/apimember/services/rest/member/insertOrUpdateMember/" . $objXML->result . "";
$arrCurlOptions2 = array(
    CURLOPT_URL => $strUrlProbe,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_POST => true,
    CURLOPT_POSTFIELDS => $strXMLPost
);
curl_setopt_array($objCurlProbe, $arrCurlOptions2);
$strCurlXMLResult = curl_exec($objCurlProbe);
echo "<pre>";
var_dump(htmlentities($objXML->result));
var_dump(htmlentities($strXMLPost));
var_dump(htmlentities($strCurlXMLResult));
curl_close($objCurlProbe);
$objXMLResult = simplexml_load_string($strCurlXMLResult);
var_dump($objXMLResult);
?>

输出如下:

string(84) "*tokenkey*"
string(615) "

取自API文档:

***Insert or Update Member Data***
This method searches a specified column of the Member table for a particular value used to identify a member
in order to update the member's data. If the member is not found, a new member is created. Any criteria can
be used to find the member including one of the fields to be updated.
The memberUID attribute is used to specify the key and value used as search criteria. The dynContent attribute
should only contain the values to be updated.
**insertOrUpdateMember**
***Input***
