PHP WebService得到通讯的SOAP包内容

在进行WebService调试时，有时需要查看接收和发送的SOAP包内容，在服务端可以比较容易的得到通讯的SOAP包内容。

服务端：

 

class Math{/** * Add Function (Can not use Chinese) * * @param integer $a * @param integer $b * @return integer */function Add($a, $b) {return $a + $b;}function Sub($a, $b) {return $a - $b;}}$strRequest = file_get_contents("php://input");file_put_contents('request.txt',$strRequest);ob_start();$server=new SoapServer('Math.wsdl',array('soap_version' => SOAP_1_2));$server->setClass("Math");$server->handle();$strResponse = ob_get_clean();file_put_contents('response.txt',$strResponse);  

客户端：

 

$a=new SoapClient("Math.wsdl");echo $a->Add(1,2); 

WSDL文件可以通过Zend Studio for Eclipse生成。

 

Request SOAP:

<?xml version="1.0" encoding="UTF-8"?><SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="urn:Math" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"><SOAP-ENV:Body><ns1:Add><a xsi:type="xsd:integer">1</a><b xsi:type="xsd:integer">2</b></ns1:Add></SOAP-ENV:Body></SOAP-ENV:Envelope> 

Response SOAP:

<?xml version="1.0" encoding="UTF-8"?><SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="urn:Math" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"><SOAP-ENV:Body><ns1:AddResponse><AddReturn xsi:type="xsd:integer">3</AddReturn></ns1:AddResponse></SOAP-ENV:Body></SOAP-ENV:Envelope> 

在这种测试环境下，客户端会得不到返回值，删除ob_start(); ob_get_clean()后，客户端将得到真实的返回结果。
