php 使用soap 协议, client 无法传递参数到server

Question

问题描述

最近在对接马来西亚的移动支付ipay88，ipay88支付平台使用的是soap+xml协议, 这个协议有点难懂，试了很久，都无法用php调试通过，用client 发出请求后，无法收到server的回复。

问题出现的环境背景及自己尝试过哪些方法

背景

开发语言: php
soap库文件: php官方的soap扩展包。
支付接口的调用地址: https://payment.ipay88.com.my/ePayment/WebService/MHGatewayService/GatewayService.svc

尝试过的内容

1. 平台无法提供任何开发语言的demo，没有代码可以参考。
2. 可以使用soapUI 来发出请求和返回。在这个工具中，发出请求是成功的。因此可以判断server端是正常工作的。
3. 客户端尝试使用SoapClient的实例,调用了__getFunctions, 可以得到正常的函数返回值，因此可以判断php的soapclient的构造没有问题.测试结果如下:

request请求
$client = new SoapClient($location,$options);
$client->__getFunctions();
response返回
[
"EntryPageFunctionalityResponse EntryPageFunctionality(EntryPageFunctionality $parameters)",
"EntryPageFunctionalityResponse EntryPageFunctionality(EntryPageFunctionality $parameters)"
]

4.但是调用server端的函数时，失败了，php代码运行超时。我理解是__soapCall的调用参数没有写对，导致服务器接口没有返回导致的。

$result = $client->__soapCall(
                'EntryPageFunctionality',$params,
                [
                    'soapaction'=>'https://www.mobile88.com/IGatewayService/EntryPageFunctionality',
                ]
                );
            echo json_encode($result);

请求失败的原因，目前猜测，有两个可能的原因

1. 这个支付接口使用的是wsdl文件, 但是这个wsdl下有两个web service, 一个webservice是http协议，还有一个webservice是https协议。我可能调用到了http协议的那个webservice。但是不知道应该如何设置__soapCall方法的参数，来调用到https协议的webservice。
2. 传递过去的参数中，key值的格式有问题。不是我代码中'requestModelObj'这样的格式，而是其他的形式。

你期待的结果是什么？实际看到的错误信息又是什么？

期待结果: response 返回xml格式的字符串。
实际情况: php代码运行超时, 应该是接口迟迟没有返回，导致超时。
