SoapException Server无法处理PHP中的ASMX Web服务上的请求

Question

我正在使用Soap API，并且在卷曲结果上出错。

  

“ soap：ServerServer无法处理请求。--->值不能为   空值。参数名称：s“

我正在为该任务使用PHP

$datasource = 'testdatasource';
$url = 'HOSTNAME:8182/merlin.asmx';

$soapEnvelope = '<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchemainstance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"
