Question

我正在尝试编写我的第一个SOAP服务器，用SOAP客户端做了一些工作。当我尝试发送一个字符串时，这很好。但是当试图向服务器发送多个参数时，我正在崩溃。有没有更好的方法来解决这个问题？

服务器：

<?php    
if(!extension_loaded("soap")){
    dl("php_soap.dll");
}
ini_set("soap.wsdl_cache_enabled","0");

function getCatalogEntry($array){
$conn = mysqli_connect($host,$user,$password,$db) or die(mysqli_error($conn));
$sql = "SELECT '" . $array[0]. "' FROM soap WHERE id = '".$array[1]."'";


$result = $conn->query($sql) or die(mysqli_error($conn));
$row = mysqli_fetch_array($result);
    return var_dump($array).$array[0];//$sql.$row[$field];
}

$server = new SoapServer("test.wsdl");
$server->AddFunction("getCatalogEntry");
$server->handle();
?>

客户端：

<?php
try{
    $sClient = new SoapClient('server.php?wsdl');

    $params = array( 
        "field" => "field2",
        "id" => "id"); 

    $response = $sClient->getCatalogEntry($params);

    var_dump($response);


} catch(SoapFault $e){
    var_dump($e);
}
?>

WSDL：

  targetNamespace='http://example.org/catalog'

  </service>
</definitions>

我发现您的问题是var_dump()，但var_dump没有返回值。

请改用var_export()。看看the manual。

所以在你的代码中，这将是：

$result = $conn->query($sql) or die(mysqli_error($conn));
$row = mysqli_fetch_array($result);
return var_export($array,true);
