php - 无法在 php 中创建我的第一个 SOAP 服务

问题描述

我正在尝试构建我的第一个 SOAP Web 服务器，但我失败了。我尝试了几个教程，但没有一个有效。以下是我迄今为止尝试过的：

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);

客户端脚本：

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>';

当我调用我的页面时https://mydomain/soap_client.php，我得到

过错

Array
(
    [faultcode] => SOAP-ENV:Client
    [faultactor] => 
    [faultstring] => error in msg parsing:
xml was empty, didn't parse!
    [detail] => 
)

要求

POST /dss/soap_server.php HTTP/1.0
Host: mydomain
User-Agent: NuSOAP/0.9.5 (1.123)
Content-Type: text/xml; charset=utf-8
SOAPAction: ""
Content-Length: 507

<?xml version="1.0" encoding="utf-8"?><SOAP-ENV:Envelope SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"><SOAP-ENV:Body><ns9471:getProd xmlns:ns9471="http://tempuri.org"><category xsi:type="xsd:string">books</category></ns9471:getProd></SOAP-ENV:Body></SOAP-ENV:Envelope>

回复

  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/">
<SOAP-ENV:Body><SOAP-ENV:Fault><faultcode xsi:type="xsd:string">SOAP-ENV:Client</faultcode><faultactor xsi:type="xsd:string"></faultactor><faultstring xsi:type="xsd:string">error in msg parsing:
xml was empty, didn&apos;t parse!</faultstring><detail xsi:type="xsd:string"></detail></SOAP-ENV:Fault></SOAP-ENV:Body></SOAP-ENV:Envelope>

如果需要我也可以提供htmlspecialchars($client->debug_str, ENT_QUOTES)。

你能帮我找到解决问题的方法吗？任何帮助将不胜感激。谢谢。

解决方案

正如 Magnus Eriksson 已经指出的那样 - 在任何情况下，我都会使用内置的原生 PHP 实现

在您的情况下，它看起来很简单（我将您的函数包装在一个名为 的类中Book）

服务器

try
{
    $objSoapServer = new SoapServer(null, ['uri' => 'http://localhost/soap/server.php']);
    $objSoapServer->setClass('Book');
    $objSoapServer->handle();
}
catch(SoapFault $e)
{
    echo $e->getMessage();
}

class Book
{
    public function getBooks($category)
    {
        if ($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";
        }
    }
}

客户

$client = new SoapClient(null, [
    'location' => "http://localhost/soap/server.php",
    'uri'      => "http://localhost/soap/server.php",
    'trace'    => 1 ]
);

echo $client->__soapCall("getBooks",["books"]);
