使用Javascript

Question

我需要在javascript中构建一个php简单服务器和一个可以访问它的小脚本。问题是我能找到的所有例子都不起作用。我只需要没有数据库的基本结构。只有回归＆＃34; hello world＆＃34;字符串到javascript客户端或任何工作示例（我可以从那一点工作）。我不知道使用Soap，nuSoap还是Rest服务器是否更好。

添加的示例：

我有这个ws：

<?php

require_once('lib/nusoap.php');

class predictiveUrlsPreloadService {

    public function getUrls($type) {
        switch ($type) {
            case 'GA':
                return 'Google Analytics code';
                break;
            case 'AA':
                return 'Adobe Analytics code';
                break;
            default:
                break;
        }
    }
}

$server = new soap_server();
$server->configureWSDL("foodservice", "http://www.greenacorn-websolutions.com/foodservice");

$server->register("predictiveUrlsPreloadService.getUrls",
    array("type" => "xsd:string"),
    array("return" => "xsd:string"),
    "http://localhost/predictiveUrlsPreloadService/service.php",
    "http://localhost/predictiveUrlsPreloadService/service.php#getUrls",
    "rpc",
    "encoded",
    "Descripci");

@$server->service(file_get_contents("php://input"));

这个PHP客户端工作：

<script
  src="https://code.jquery.com/jquery-3.2.1.min.js"
  integrity="sha256-hwg4gsxgFZhOsEEamdOYGBf13FyQuiTwlAQgxVSNgt4="
  crossorigin="anonymous">
</script>

<?php

require_once('lib/nusoap.php');

$wsdl = "http://localhost/predictiveUrlsPreloadService/wsdl.wsdl";

$client = new nusoap_client($wsdl, true);
$error  = $client->getError();

if ($error) {
    print_r($error);
}

$result = $client->call("predictiveUrlsPreloadService.getUrls", array("type" => 'GA'));

if ($client->fault) {
    print_r($result);
} else {
    $error = $client->getError();
    if ($error) {
        print_r($error);
    } else {
        echo $result;
    }
}

?>

所有这一切都与它的wsdl。我只需要知道如何使用javascript或ajax进行调用：

$.ajax({
    url: 'http://localhost/predictiveUrlsPreloadService/service.php', 
    type: "predictiveUrlsPreloadService.getUrls",
    data: {
      'type' : 'AA'
    }, 
    success:  function (response) {
    console.dir(response);
  }
});

但它只返回ws信息。我怎么能这样做？

这比我想象的要简单。

这是PHP中的nusoap服务器：

<?php
    require_once('nusoap.php');

    $server = new soap_server();
    $server->configureWSDL("PredictiveUrlPreloadXML", "urn:PredictiveUrlPreloadXMLwsdl");
    $server->wsdl->schemaTargetNamespace = "urn:PredictiveUrlPreloadXMLwsdl";

    function getUrls($type) {
        switch ($type) {
            case 'GA': 
                return 'GA code';
                break;
            case 'AA':
                return 'AA code';
                break;
            default:
                return null;
                break;
        }
    }

    $server->register(
        'getUrls',                                     
        array(                                     
            'type'          => 'xsd:string',
        ),               
        array(
            'return'        => 'xsd:string'
        ),             
        'urn:PredictiveUrlPreloadXMLwsdl',              
        'urn:PredictiveUrlPreloadXMLwsdl#getUrls',
        'rpc',                                     
        'encoded',                                      
        'Desc'    
    );

    @$server->service(file_get_contents("php://input"));

?>

这是javascript客户端：

<script>

    var soapMessage =
        '<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">'+
            '<soap:Body>'+
                '<getUrls xmlns="urn:PredictiveUrlPreloadXMLwsdl">'+
                    '<type>GA</type>'+
                '</getUrls>'+
            '</soap:Body>'+
        '</soap:Envelope>';

    $.ajax({
        url: "http://localhost/predictive_url_preload/ws.php",
        type: "POST",
        dataType: "xml", 
        contentType: "text/xml",
        data: soapMessage, 
        success: function(data, status, req) {
           //TODO
        },
        error: function (data, status, req) {
            console.log(req);
        }
    });

</script>
