php - 如何转储 SoapClient 请求进行调试？

Question

我需要调试一些使用 soap 客户端的代码。我在 php.net 中找到了 getLast* 方法，但是当我尝试获取最后一个调试请求时，它返回 NULL

<?php

    $client = new SoapClient("http://www.webservicex.net/ConverPower.asmx?WSDL");
    
    $response = $client->ChangePowerUnit(array(
        "PowerValue" => 100,
        "fromPowerUnit" => "horsepower",
        "toPowerUnit" => "megawatts"
    ));
    
    
    echo "====== REQUEST HEADERS =====" . PHP_EOL;
    var_dump($client->__getLastRequestHeaders());
    echo "========= REQUEST ==========" . PHP_EOL;
    var_dump($client->__getLastRequest());
    echo "========= RESPONSE =========" . PHP_EOL;
    var_dump($response);

?>

代码执行结果:

$php soap_test.php 

====== REQUEST HEADERS =====
NULL
========= REQUEST ==========
NULL
========= RESPONSE =========
object(stdClass)#2 (1) {
  ["ChangePowerUnitResult"]=>
  float(0.0746)
}

如何获取上一次SoapClient请求的body和headers的内容？

Answer 1

These functions 仅当创建 SoapClient 对象时 trace 选项设置为 TRUE 时才有效。

尝试:

$client = new SoapClient("http://www.webservicex.net/ConverPower.asmx?WSDL", array('trace' => 1));
