我正在利用基于SOAP-的API将现有软件包与第三方软件包集成。但是，我无法从上次请求中生成XML来帮助进行故障排除，因为我不相信实际会进行调用。我能想到的唯一合乎逻辑的解释是，PHP在实际发送请求之前根据WSDL验证请求。这个问题不需要代码，我已经尝试了太多的变体，无法选择一两个样本进行共享。我已经用一个有效的SOAP调用替换了有故障的SOAP调用，XML生成并按预期成功返回。
是否有人知道如何确定PHP是否正在发出请求而请求失败，或者是否有可能让PHP根据WSDL使请求无效而根本无法发出调用？
如果您有问题，请随时提问。我很感激你的帮助！
试着调试你的脚本，看看它是否真的在发出请求，PHP的SoapClient对象让它变得很容易。看看SoapClient:：_getLastRequest和SoapClient：：_getLastResponse。
如果你想要更低一点的东西，ngrep是一个很好的简单工具，可以监视电线上发生的事情。
以这个简单的PHP脚本为例。。。
<?php
$client = new SoapClient('http://www.27seconds.com/kb/ws/Articles.asmx?WSDL');
$article = $client->GetArticle(array('articleId' => 7));
执行ngrep port 80 &，然后执行上面的脚本会转储流量，看起来应该类似于。。。

注意到SOAP调用了吗？有很多其他方法可以做到这一点，但调试应该是您的第一个调用端口。：）
祝你好运，
安东尼。
看起来您的问题是：您正试图通过服务器端的PHP进行SOAP调用，但您不知道是否进行了调用。
如果您想检查是否进行了调用，可以将SOAP对象替换为您的mock对象，并在mock对象中尝试查看是否进行了该调用。
