这是我第一次使用 XML-RPC。我在从服务器检索数据时遇到问题，因为它作为故障代码返回给客户端。为什么会这样？我还需要制作一个 XML-RPC 服务器文件还是已经在这里设置了？

$beerClient = new xmlrpc_client('localhost:1234/341/xmlrpc-lab/xmlrpcserver.php','alvin.ist.rit.edu:8100',1234);

是因为数据与服务器返回类型不匹配还是我缺少的其他东西？

我确保将 xmlrpc 库包含在正确的路径和所有内容中。

网页错误返回：

An XML-RPC Fault Occured
Fault Code:-1
Fault Desc:java.lang.NoSuchMethodException: BeerHandler.List()

XML-RPC 客户端：

<?php

    require_once('xmlrpc-3.0.0.beta/lib/xmlrpc.inc');

    //  Initialize $Beers as an empty Array. 
    //  $Beers will hold all the information available for each beer. 
    //     (BeerID, Name, Rating, Comments)
    //  
    //  It will be used later to create the HTML output.
    $Beers = Array();

    //  GET A LIST OF THE AVAILABLE BEERS ON THE XML-RPC SERVER

    $beerClient = new xmlrpc_client('localhost:1234/341/xmlrpc-lab/xmlrpcserver.php','alvin.ist.rit.edu:8100',1234);

    $response = $beerClient->send($msg_listBeers);
    if($response == false)

           //    b) Comments
           //  
           //  and put the data into the $Beer array. This is incredibly
           //  inefficient since it performs a lot of HTTP calls to grab each
           //  piece of data. Not recommended for use beyond this example.
           $Beers[$beerID]['name'] = $beerName;

           // GET THE RATING FOR THE CURRENT BEER
           // Build XML-RPC Request for the Beer's Rating

           $msg_beerRating = new xmlrpcmsg('beer.Rating',array(new xmlrpcval($beerID, 'int')));

           // Send the Message to the server
           $response = $beerClient->send($msg_beerRating);

           // Negative number If no rating found
           $Beers[$beerID]['rating'] = (!$response->faultCode()) ? xmlrpc_decode($response->value()) : -1;

           //  GET THE COMMENTS FOR THE CURRENT BEER

           $msg_beerComments = new xmlrpcmsg('beer.Comments', array(new xmlrpcval($beerID,'int')));

           // Send the Message to the server
           $response = $beerClient->send($msg_beerComments);

           // Fill in the Comments for the Beer
           $Beers[$beerID]['comments'] = (!$response->faultCode()) ? xmlrpc_decode($response->value()) : array(); //empty array for not Comments

        } // END foreach ($beerList as ...
    }
    else // XML-RPC returned a fault...
    {
        echo '<h1>An XML-RPC Fault Occured</h1>';
        printf('<b>Fault Code:</b>%s<br/>',$response->faultCode());
        printf('<b>Fault Desc:</b>%s<br/>',$response->faultString());
        die();
    }

    // GENERATE THE OUTPUT





    $xmlrpc_client->setDebug(1); // turn on debugging, if I/O fault occurred between communication xmlrpc_client and xmlrpc_server
