如何轉儲SoapClient調試請求？

Question

我需要調試使用soap客戶端的代碼。我發現php.net getLast *方法，但是當我試圖獲得最後的要求進行調試，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); 

?> 

代碼執行的結果：

$php soap_test.php 

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

如何得到身體的內容和最後的SoapClient請求的標題？如果SoapClient的創建對象設置爲TRUE跟蹤選項

Answer 1

These functions纔有效。

嘗試：

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