PHP SOAP服务器是否通过HTTP POST处理请求？

Question

我正在尝试使用php设置一个Web服务。我已经成功地使用PHP SOAP扩展创建了一个。但是，我希望通过简单的HTTP POST和HTTP GET调用来提供服务。为了简单起见，我试图将http://www.w3schools.com/webservices/ws_example.asp的示例翻译为在php环境中工作。

服务器localhost / tempconvert.php如下所示：

<?php
    function CelsiusToFahrenheit($celcius){
        return (((($celcius) * 9) / 5) + 32);
    }

    function FahrenheitToCelsius($fahrenheit){
        return (((($fahrenheit) - 32) / 9) * 5);
    }

    // turn off the wsdl cache
    ini_set("soap.wsdl_cache_enabled", "0");

    $server = new SoapServer("tempconvert.wsdl");

    $server->addFunction("CelsiusToFahrenheit");
    $server->addFunction("FahrenheitToCelsius");

    $server->handle();
?>

，客户端localhost / tempclient.php如下所示：

<?php
    // turn off the WSDL cache
    ini_set("soap.wsdl_cache_enabled", "0");

    $client = new SoapClient("tempconvert.wsdl");

    $cels = 32;
    $fahr = $client->CelsiusToFahrenheit($cels);

    echo "$cels in fahr is: $fahr";
?>

最后wsdl文件localhost / tempconvert.wsdl看起来像：

          <http:address location="http://localhost/tempconvert.php" />
        </wsdl:port>
      </wsdl:service>
    </wsdl:definitions>

使用客户端工作正常并输出相关结果。使用localhost / tempconvert.php调用服务器？WSDL输出wsdl内容。

但是，使用有效负载Celsius = 100的HTTP POST端口调用服务器localhost / tempcovert.php不起作用并提供HTTP错误500响应？

SOAP扩展功能不应该解决这个问题吗？

...或者我必须自己在服务器文件中添加功能吗？ （比如使用：if（$ _POST）...）
