如何使用Soap服务器下载XML内容并使用PHP和nusoap通过Soap客户端使用XML内容

Question

我正在使用肥皂服务器和客户端来测试客户端与服务器之间的通信。因此，我在服务器端有一个XML文件。我需要使用SOAP客户端服务器在客户端中访问该文件。我很困惑如何从服务器获取该XML文件并从客户端使用它。拜托，任何人，请帮帮我。提前致谢。

服务器端代码

require 'nusoap/lib/nusoap.php';
require_once 'functions.php';
$server = new nusoap_server();

$server->configureWSDL('demo', 'urn:demo');

$server->register('peekMessages', array(), array("peekMessagesReturn" => "impl:ArrayOf_xsd_string"));

//$HTTP_RAW_POST_DATA = isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : '';
$postdata = file_get_contents("php://input");

$server->service($postdata);

Functions.php

function peekMessages()
{
    $xml = simplexml_load_file("http://localhost/Projects/soap-server/xml/message-data.xml");
    return $xml;

}

客户端代码：

require 'nusoap/lib/nusoap.php';


$client = new nusoap_client("http://localhost/Projects/soap-server/server.php?wsdl", true);
$client->soap_defencoding = 'UTF-8';
$client->decode_utf8 = FALSE;

$book = "abc";


//$data = $client->call('price', array("name"=> "$book"));
$data = $client->call('peekMessages');

echo json_encode($data);

XML格式

<?xml version="1.0"?>
