无法在php中创建我的第一个SOAP服务

我正在尝试构建我的第一个SOAP web服务器，但失败了。我尝试了几本教程，但都不管用。以下是我迄今为止尝试过的内容：

服务器脚本：

require_once "lib/nusoap.php";

function getProd($category) {
    if ($category == "books") {
        return join(",", array(
            "The WordPress Anthology",
            "PHP Master: Write Cutting Edge Code",
            "Build Your Own Website the Right Way"));
    }
    else {
            return "No products listed under that category";
    }
}

$server = new soap_server();
$server->soap_defencoding = 'utf-8';
$server->register("getProd");
$server->service($HTTP_RAW_POST_DATA);

require_once "lib/nusoap.php";

$client = new nusoap_client("https://mydomain/soap_server.php");
$client->soap_defencoding = 'utf-8';

$error = $client->getError();
if ($error) {
    echo "<h2>Constructor error</h2><pre>" . $error . "</pre>";
}

$result = $client->call("getProd", array("category" => "books"));

if ($client->fault) {
    echo "<h2>Fault</h2><pre>";
    print_r($result);
    echo "</pre>";
}
else {
    $error = $client->getError();
    if ($error) {
        echo "<h2>Error</h2><pre>" . $error . "</pre>";
    }
    else {
        echo "<h2>Books</h2><pre>";
        echo $result;
        echo "</pre>";
    }
}


echo '<h2> Request</h2><pre>' . htmlspecialchars($client->request, ENT_QUOTES) . '</pre></br>';
echo '<h2> Response</h2><pre>' . htmlspecialchars($client->response, ENT_QUOTES) . '</pre></br>';
echo '<h2>Debug</h2><pre>' . htmlspecialchars($client->debug_str, ENT_QUOTES) . '</pre></br>';

客户端脚本：

require_once "lib/nusoap.php";

function getProd($category) {
    if ($category == "books") {
        return join(",", array(
            "The WordPress Anthology",
            "PHP Master: Write Cutting Edge Code",
            "Build Your Own Website the Right Way"));
    }
    else {
            return "No products listed under that category";
    }
}

$server = new soap_server();
$server->soap_defencoding = 'utf-8';
$server->register("getProd");
$server->service($HTTP_RAW_POST_DATA);

require_once "lib/nusoap.php";

$client = new nusoap_client("https://mydomain/soap_server.php");
$client->soap_defencoding = 'utf-8';

$error = $client->getError();
if ($error) {
    echo "<h2>Constructor error</h2><pre>" . $error . "</pre>";
}

$result = $client->call("getProd", array("category" => "books"));

if ($client->fault) {
    echo "<h2>Fault</h2><pre>";
    print_r($result);
    echo "</pre>";
}
else {
    $error = $client->getError();
    if ($error) {
        echo "<h2>Error</h2><pre>" . $error . "</pre>";
    }
    else {
        echo "<h2>Books</h2><pre>";
        echo $result;
        echo "</pre>";
    }
}


echo '<h2> Request</h2><pre>' . htmlspecialchars($client->request, ENT_QUOTES) . '</pre></br>';
echo '<h2> Response</h2><pre>' . htmlspecialchars($client->response, ENT_QUOTES) . '</pre></br>';
echo '<h2>Debug</h2><pre>' . htmlspecialchars($client->debug_str, ENT_QUOTES) . '</pre></br>';

请求

POST/dss/soap\u server.php HTTP/1.0
主持人：mydomain
用户代理：NuSOAP/0.9.5（1.123）
内容类型：text/xml；字符集=utf-8
SOAPAction:“
内容长度：507
书

响应

HTTP/1.1500内部服务器错误
服务器：nginx
日期：2018年8月26日星期日07:49:26 GMT
内容类型：text/xml；字符集=utf-8
内容长度：684

消息解析中的SOAP-ENV:Clienterror:
xml是空的，没有&apos；t解析！

如果需要，我还可以提供

htmlspecialchars（$client->debug\u str，ENT\u QUOTES）

你能帮我找到解决问题的方法吗？ 任何帮助都将被告知。

谢谢。

正如Magnus Eriksson已经指出的那样-无论如何，我都会使用本机内置的PHP实现

在您的例子中，它看起来非常简单（我将您的函数包装在一个名为

Book

的类中）

服务器

客户端

有关更多信息，请查看官方文档

当PHP5出现时，他们还实现了Soap服务器和客户端的本机实现。它们可能更稳定，并且具有更好的性能（以及适当的文档）。如果由于某种原因无法安装本机soap扩展，请将NuSoap视为一种后备方案。NuSoap有点“过时”。最好使用本机SOAP扩展或zend SOAP库。大多数来自谷歌的“如何”点击都是基于nusoap的，所以我尝试了这个。我将测试提供的解决方案。
