php - 我可以在发送之前预览 PHP SOAP 要发送的 XML 吗？

Question

根据标题，是否可以在尝试运行 __soapCall() 之前输出 new SoapClient 创建的 XML，以确保在实际发送之前它是正确的它到 SOAP 服务器？

Answer 1

您可以使用派生类并覆盖 __doRequest() method SoapClient 类。

<?php
//$clientClass = 'SoapClient';
$clientClass = 'DebugSoapClient';
$client = new $clientClass('http://www.webservicex.com/CurrencyConvertor.asmx?wsdl');
$client->sendRequest = false;
$client->printRequest = true;
$client->formatXML = true;

$res = $client->ConversionRate( array('FromCurrency'=>'USD', 'ToCurrency'=>'EUR') );
var_dump($res);

class DebugSoapClient extends SoapClient {
  public $sendRequest = true;
  public $printRequest = false;
  public $formatXML = false;

  public function __doRequest($request, $location, $action, $version, $one_way=0) {
    if ( $this->printRequest ) {
      if ( !$this->formatXML ) {
        $out = $request;
      }
      else {
        $doc = new DOMDocument;
        $doc->preserveWhiteSpace = false;
        $doc->loadxml($request);
        $doc->formatOutput = true;
        $out = $doc->savexml();
      }
      echo $out;
    }

    if ( $this->sendRequest ) {
      return parent::__doRequest($request, $location, $action, $version, $one_way);
    }
    else {
      return '';
    }
  }
}

打印

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns1="http://www.webserviceX.NET/">
  <SOAP-ENV:Body>
    <ns1:ConversionRate>
      <ns1:FromCurrency>USD</ns1:FromCurrency>
      <ns1:ToCurrency>EUR</ns1:ToCurrency>
    </ns1:ConversionRate>
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>
NULL

但是您必须稍微更改实际代码才能使其正常工作，我会尽可能避免这种情况(即让工具完成工作)。
