Question

我有一个PHP SOAP Web服务充当中继来调用跨域Web服务。我遇到的问题是从JavaScript调用我的本地PHP Web服务方法（使用JQuery / Ajax）。我想在我的网络服务中调用一个特定的方法;例如“LoginToAccount”;

我没有兴趣在URL中添加params然后找出要调用的方法......这在.NET中是非常简单的（mywebservice.asmx / LoginToAccount“）但是无法弄明白如何让它在PHP中工作。

我不断收到“错误请求”的“500内部服务器错误”：错误的要求

这是我的PHP代码：

<?php 

function LoginToAccount($email, $passCodeHash) { 
    //...code calling cross-domain web services
    return $jsonEncodedResponse;
  }


function CreateAccount($email, $passCodeHash){
    //...code calling cross-domain web services
    return $jsonEncodedResponse;
}

$server = new SoapServer(null, array('uri'  => "http://www.myurl/webservices/"));

$server->addFunction('LoginToAccount');
$server->addFunction('CreateAccount');
$server->handle();
?>

这是我的JavaScript代码：

function AjaxCall() {
    $.ajax({
        type: "POST",
        url: "phpRelay.php/LoginToAccount",
        data: "{email : 'myEmail@email.com', passCodeHash: '12345'}",
        contentType: "application/json",
        dataType: "json",
        success: succeeded,
        error: queryError
    });
}

function succeeded(data, textStatus, request) {
    var result = $.parseJSON(data.d);

}

function queryError(request, textStatus, errorThrown) {
    alert(request.responseText, textStatus + " " + errorThrown);
}

这都在同一个域上。谢谢！

Answer 1

而不是使用php soapserver，您可以使用以下代码替换它：

echo $data = (function_exists($_SERVER['QUERY_STRING'])) ? json_encode(array('d'=>$_SERVER['QUERY_STRING'](file_get_contents('php://input')))) : 'error: function does not exists';

它的作用是使用query_string作为函数名。它首先检查函数是否存在，如果不是，则打印错误，但如果存在，则以字符串格式调用带有发布数据作为条件的函数。最后，函数返回的数据打印为json数组，结果设置为d。

所以你的javascript应该如下（注意url调用应该是？而不是/在函数之前）：

function AjaxCall() {
    $.ajax({
        type: "POST",
        url: "phpRelay.php?LoginToAccount",
        data: "{email : 'myEmail@email.com', passCodeHash: '12345'}",
        contentType: "application/json",
        dataType: "json",
        success: succeeded,
        error: queryError
    });
}

function succeeded(data, textStatus, request) {
    var result = $.parseJSON(data.d);

}

function queryError(request, textStatus, errorThrown) {
    alert(request.responseText, textStatus + " " + errorThrown);
}

希望这可以帮到你！我知道发布这个有点晚了，但如果有其他人需要这样的东西我发布了它！我需要它，不能有这样的任何解决方案，所以我必须自己制定解决方案。

我尝试过使用ajax客户端的SOAP PHP服务器并找到了工作代码

首先从Here

下载nusoap库

然后创建 server.php

<?php
//call library 
require_once ('lib/nusoap.php'); 

// Define the TriangleArea method as a PHP function 
function TriangleArea($b, $h) { return 'The triangle area is: ' .(($b*$h)/2); } 
// Define the RectangleArea method as a PHP function 
function RectangleArea($L, $l) { return 'The rectangle area is: ' .($L*$l); }
// create the function 
function get_message($your_name) 
{ 
if(!$your_name){ 
return new soap_fault('Client','','Put Your Name!'); 
} 
$result = "Welcome to ".$your_name .". Thanks for Your First Web Service Using PHP with SOAP"; 
return $result; 
}


//using soap_server to create server object 
$server = new soap_server; 

// Initialize WSDL support 
$server->configureWSDL('mathwsdl', 'urn:mathwsdl'); 


 // Register the TriangleArea method 
   $server->register('TriangleArea',                  // method name
       array('b' => 'xsd:int', 'h' => 'xsd:int'),     // input parameters
       array('area_t' => 'xsd:string'),               // output parameters
       'urn:mathwsdl',                                // namespace
       'urn:mathwsdl#TriangleArea',                   // soapaction
       'rpc',                                         // style
       'encoded',                                     // use
       '1=> : Calculate a triangle area as (b*h)/2'         // documentation
   );

   // Register the RectangleArea method to expose
   $server->register('RectangleArea',                 // method name
       array('L' => 'xsd:int', 'l' => 'xsd:int'),     // input parameters
       array('area_r' => 'xsd:string'),               // output parameters
       'urn:mathwsdl',                                // namespace
       'urn:RectangleAreawsdl#RectangleArea',         // soapaction
       'rpc',                                         // style
       'encoded',                                     // use
       '2=> : Calculate a rectangle area as (L*l)'          // documentation
   );


    // Register the RectangleArea method to expose
   $server->register('get_message',                 // method name
       array('nm' => 'xsd:string'),     // input parameters
       array('area_r' => 'xsd:string'),               // output parameters
       'urn:mathwsdl',                                // namespace
       'urn:get_messagewsdl#get_message',         // soapaction
       'rpc',                                         // style
       'encoded',                                     // use
       '3=> : Print a Message as name'          // documentation
   ); 




if ( !isset( $HTTP_RAW_POST_DATA ) ) $HTTP_RAW_POST_DATA =file_get_contents( 'php://input' );
$server->service($HTTP_RAW_POST_DATA);
// create HTTP listener 
//$server->service($HTTP_RAW_POST_DATA); 
exit(); 
?>

之后创建 client.php

<?php 
require_once ('lib/nusoap.php'); 
//Give it value at parameter 
$param = array( 'your_name' => 'Monotosh Roy'); 
//Create object that referer a web services
$client = new soapclient('http://localhost:81/WebServiceSOAP/server.php?wsdl', true); 

 // Check for an error
   $err = $client->getError();
   if ($err) {
      // Display the error
      echo '<h2>Constructor error</h2><pre>' . $err . '</pre>';
      // At this point, you know any calls to 
      // this web service's methods will fail
   }


   // Call the TriangleArea SOAP method
   $result = $client->call('TriangleArea', 
      array('b' => 10, 'h' => 15));

   // Check for a fault
   if ($client->fault) {
       echo '<h2>Fault</h2><pre>';
       print_r($result);
       echo '</pre>';
   } else {
       // Check for errors
       $err = $client->getError();
       if ($err) {
           // Display the error
           echo '<h2>Error</h2><pre>' . $err . '</pre>';
       } else {
           // Display the result
           echo '<h2>Result</h2><pre>';
           print_r($result);
       echo '</pre>';
       }
   }
   // Call the RectangleArea SOAP method
   $result = $client->call('RectangleArea', 
      array('L' => 40, 'l' => 20));

   // Check for a fault
   if ($client->fault) {
       echo '<h2>Fault</h2><pre>';
       print_r($result);
       echo '</pre>';
   } else {
       // Check for errors
       $err = $client->getError();
       if ($err) {
           // Display the error
           echo '<h2>Error</h2><pre>' . $err . '</pre>';
       } else {
           // Display the result
           echo '<h2>Result</h2><pre>';
           print_r($result);
       echo '</pre>';
       }
   }

    // Display the request and response
  /* echo '<h2>Request</h2>';
   echo '<pre>' . htmlspecialchars($client->request, 
      ENT_QUOTES) . '</pre>';
   echo '<h2>Response</h2>';
   echo '<pre>' . htmlspecialchars($client->response, 
      ENT_QUOTES) . '</pre>';*/

//Call a function at server and send parameters too 
$response = $client->call('get_message',$param); 
//Process result 
if($client->fault) 
{ 
echo "<h2>FAULT:</h2> <p>Code: (".$client->faultcode."</p>"; 
echo "String: ".$client->faultstring; 
} 
else 
{ 
echo $response; 
} 
?>
