我正在使用基於SOAP的API將現有軟件包與第三方軟件包集成。但是，我無法從最後一次請求中生成XML以幫助排除故障，因爲我不相信實際發生的呼叫。我能想出的唯一合乎邏輯的解釋是，在實際發送請求之前，PHP正在驗證對WSDL的請求。該代碼對於這個問題不是必需的，並且我嘗試了太多的變體來挑選一個或兩個樣本進行分享。我用有效的SOAP調用替換了錯誤的SOAP調用，並且按預期成功生成並返回了XML。PHP在發送請求之前是否驗證WSDL請求？
有誰知道如何確定PHP是否發出請求並且請求失敗，或者是否有可能使PHP對WSDL無效並且根本無法進行調用？
如果您有任何問題，請隨時詢問。我感謝幫助！
嘗試調試腳本以查看它是否實際發出請求，PHP的SoapClient對象使其非常容易。看看SoapClient::_getLastRequest和SoapClient::_getLastResponse。
如果你想要更低一點的東西，ngrep是一個很好的簡單工具，可以關注線路上發生的事情。
把這個簡單的PHP腳本...
<?php
$client = new SoapClient('http://www.27seconds.com/kb/ws/Articles.asmx?WSDL');
$article = $client->GetArticle(array('articleId' => 7));
執行ngrep port 80 &，然後執行上面的腳本將轉儲交通，它應該類似於此...

公告SOAP調用？還有很多其他方法可以做到這一點，但調試應該是您的第一個停靠點。 :)
祝你好運，
安東尼。
它看起來像你的問題是：你試圖通過PHP在服務器端進行SOAP調用，你不知道是否調用。
如果您想檢查是否進行了調用，您可以用您的模擬對象替換SOAP對象，並在模擬對象中嘗試查看調用是否發生。
