Question

我想通过使用NuSOAP生成WSDL来通过SOAP查询一些内容我知道有很多与该主题有关的问题，但我没有成功地使代码适应我的特定问题。

我成功生成了WSDL代码，它只返回一个结构数组（关联数组），但是我宁愿返回一个包含整数变量的对象（struct），一个字符串变量和一个数组结构

所以，这是用于返回结构数组的代码：

<?php

    function getStuffs( $user='', $pass='' ) {
        // here we can check user and pass and do whatever (if it isn't alright, we can throw exception or return NULL or sg. similar)
        // .......

        $stuff_array   = array();
        $stuff_array[] = array( 'id'=>122, 'name'=>'One stuff');
        $stuff_array[] = array( 'id'=>213, 'name'=>'Another stuff');
        $stuff_array[] = array( 'id'=>435, 'name'=>'Whatever stuff');
        $stuff_array[] = array( 'id'=>65, 'name'=>'Cool Stuff');
        $stuff_array[] = array( 'id'=>92, 'name'=>'Wow, what a stuff');    

        return $stuff_array;
    }

    require_once 'nusoap/lib/nusoap.php';
    $server = new soap_server;

    // $myNamespace = $_SERVER['SCRIPT_URI'];
    $myNamespace = 'http://'.$_SERVER['HTTP_HOST'].$_SERVER['SCRIPT_NAME'];

    $server->configureWSDL('MyStuffService', 'urn:' . $myNamespace);
    // $server->wsdl->schemaTargetNamespace = 'http://soapinterop.org/xsd/';

    $server->wsdl->addComplexType(
        // name
        'Stuffs',
        // typeClass (complexType|simpleType|attribute)
        'complexType',
        // phpType: currently supported are array and struct (php assoc array)
        'struct',
        // compositor (all|sequence|choice)
        'all',
        // restrictionBase namespace:name (http://schemas.xmlsoap.org/soap/encoding/:Array)
        '',
        // elements = array ( name = array(name=>'',type=>'') )
        array(
            'id' => array(
                'name' => 'id',
                'type' => 'xsd:int'
            ),
            'name' => array(
                'name' => 'name',
                'type' => 'xsd:string'
            )
        )
    );  

    $server->wsdl->addComplexType(
        // name
        'StuffsArray',
        // typeClass (complexType|simpleType|attribute)
        'complexType',
        // phpType: currently supported are array and struct (php assoc array)
        'array',
        // compositor (all|sequence|choice)
        '',
        // restrictionBase namespace:name (http://schemas.xmlsoap.org/soap/encoding/:Array)
        'SOAP-ENC:Array',
        // elements = array ( name = array(name=>'',type=>'') )
        array(),
        // attrs
        array(
            array(
                'ref' => 'SOAP-ENC:arrayType',
                'wsdl:arrayType' => 'tns:Stuffs[]'
            )
        ),
        // arrayType: namespace:name (http://www.w3.org/2001/XMLSchema:string)
        'tns:Stuffs'
    );

    $server->register(
        // string $name the name of the PHP function, class.method or class..method
        'getStuffs',
        // array $in assoc array of input values: key = param name, value = param type
        array(
            'user' => 'xsd:string',
            'pass' => 'xsd:string'
        ),
        // array $out assoc array of output values: key = param name, value = param type
        array(
            'return' => 'tns:StuffsArray'
        ),
        // mixed $namespace the element namespace for the method or false
        'urn:' . $myNamespace,
        // mixed $soapaction the soapaction for the method or false
        'urn:' . $myNamespace . "#getStuffs",
        // mixed $style optional (rpc|document) or false Note: when 'document' is specified, parameter and return wrappers are created for you automatically
        'rpc',
        // mixed $use optional (encoded|literal) or false
        'encoded',
        // string $documentation optional Description to include in WSDL
        'Fetch array of Stuffs ("id", "name").' // documentation
    );

    #$server->wsdl->schemaTargetNamespace = $myNamespace;
    $server->service(isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : '');
    exit();

?>

在C＃控制台应用程序中，添加一个名为“StuffService”的Web引用并将“？wsdl”附加到可以找到此PHP文件的相应URL后，此代码可以正常工作，我可以完美地查询stuff_array值这样：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace WebServiceTest
{
    class Program
    {
        static void Main(string[] args)
        {
            StuffService.MyStuffService myService = new StuffService.MyStuffService();

            StuffService.Stuffs[] stuffs = myService.getStuffs("someone", "1234");

            foreach (var stuff in stuffs)
            {
                Console.WriteLine(stuff.id+".: "+stuff.name);
            }

            Console.WriteLine();
            Console.WriteLine("Press a key...");
            Console.ReadKey();
        }
    }
}

这很酷，但我想开发这个代码来回馈这样的对象：

class ResponseObject {
    public $responseCode = 0;
    public $responseMessage = '';
    public $stuffArray = NULL;
}   

$responseObject = NULL;

function getStuffs( $user='', $pass='' ) {
    global $responseObject;

    $responseObject = new ResponseObject();

    // check stuffs in a simple way now
    if($user != 'someone' && $pass != '1234'){
        $responseObject->responseCode = 2;
        $responseObject->responseMessage = 'Authentication failed';
        return $responseObject;
    }

    $responseObject->stuffArray   = array();
    $responseObject->stuffArray[] = array( 'id'=>122, 'name'=>'One stuff');
    $responseObject->stuffArray[] = array( 'id'=>213, 'name'=>'Another stuff');
    $responseObject->stuffArray[] = array( 'id'=>435, 'name'=>'Whatever stuff');
    $responseObject->stuffArray[] = array( 'id'=>65, 'name'=>'Cool Stuff');
    $responseObject->stuffArray[] = array( 'id'=>92, 'name'=>'Wow, what a stuff');          

    $responseObject->responseCode = 1;
    $responseObject->responseMessage = 'Successful!';
    return $responseObject; 
}

适合的NuSOAP代码是什么？
谢谢！！：）

我希望我能澄清一下我想要实现的目标：返回一个包含int，字符串和结构数组的结构，但不知道如何编写适当的NuSOAP代码。这样我就可以首先检查responseCode，并使用相应的错误消息处理它或输出stuffArray等。

Answer 1

经过长时间的实验，我找到了解决方案！

因此，给出一个包含三个成员的结构 - 一个int responseCode，一个字符串responseMessage和一个名为stuffArray的结构数组 - 通过带有NuSOAP（PHP）的SOAP，如下所示，我在代码中添加了一些注释让它更明确：

<?php

    class ResponseObject {
        public $responseCode = 0;
        public $responseMessage = 'Unknown error!';
        public $stuffArray = NULL;
    }   

    /**
     * @return object
     */ 
    function getStuffs( $user='', $pass='' ) {

        $responseObject = new ResponseObject();

        // check stuffs in a simple way now
        if( !($user == 'someone' and $pass == '1234') ){
            $responseObject->responseCode = 2;
            $responseObject->responseMessage = 'Authentication failed!';
            return $responseObject;
        }

        $responseObject->stuffArray   = array();
        $responseObject->stuffArray[] = array( 'id'=>122, 'name'=>'One stuff');
        $responseObject->stuffArray[] = array( 'id'=>213, 'name'=>'Another stuff');
        $responseObject->stuffArray[] = array( 'id'=>435, 'name'=>'Whatever stuff');
        $responseObject->stuffArray[] = array( 'id'=>65, 'name'=>'Cool Stuff');
        $responseObject->stuffArray[] = array( 'id'=>92, 'name'=>'Wow, what a stuff');          

        $responseObject->responseCode = 1;
        $responseObject->responseMessage = 'Successful!';
        return $responseObject; 
    }

    require_once 'nusoap/lib/nusoap.php';
    $server = new soap_server;

    // $myNamespace = $_SERVER['SCRIPT_URI'];
    $myNamespace = 'http://'.$_SERVER['HTTP_HOST'].$_SERVER['SCRIPT_NAME'];

    $server->configureWSDL(
        // string $serviceName, name of the service
        'MyStuffService',
        // mixed $namespace optional 'tns' service namespace or false
        // 'urn:' . $myNamespace
        $myNamespace
    );

    // $server->wsdl->schemaTargetNamespace = 'http://soapinterop.org/xsd/';
    $server->wsdl->schemaTargetNamespace = $myNamespace;

    $server->wsdl->addComplexType(
        // name
        'Stuffs',
        // typeClass (complexType|simpleType|attribute)
        'complexType',
        // phpType: currently supported are array and struct (php assoc array)
        'struct',
        // compositor (all|sequence|choice)
        'all',
        // restrictionBase namespace:name (http://schemas.xmlsoap.org/soap/encoding/:Array)
        '',
        // elements = array ( name = array(name=>'',type=>'') )
        array(
            'id' => array(
                'name' => 'id',
                'type' => 'xsd:int'
            ),
            'name' => array(
                'name' => 'name',
                'type' => 'xsd:string'
            )
        )
    );  

    $server->wsdl->addComplexType(
        // name
        'StuffsArray',
        // typeClass (complexType|simpleType|attribute)
        'complexType',
        // phpType: currently supported are array and struct (php assoc array)

            array(
                'ref' => 'SOAP-ENC:arrayType',
                'wsdl:arrayType' => 'tns:Stuffs[]'
            )

    $server->wsdl->addComplexType(

        array
        (
            'responseCode' => array(   'type' => 'xsd:int'),
            'responseMessage' => array(   'type' => 'xsd:string'),
            'stuffArray'   => array(   'type' => 'tns:StuffsArray'
                                            // DON'T UNCOMMENT THE FOLLOWING COMMENTED LINES, BECAUSE THIS WAY IT DOESN'T WORK!!! - Left it in the code not to forget it....
                                            // ,
                                            // 'minOccurs' => '0',
                                            // 'maxOccurs' => 'unbounded'
                                            )
        )
    );

    $server->register(
        // string $name the name of the PHP function, class.method or class..method
        'getStuffs',
        // array $in assoc array of input values: key = param name, value = param type
        array(
            'user' => 'xsd:string',
            'pass' => 'xsd:string'
        ),
        // array $out assoc array of output values: key = param name, value = param type
        array(
            'return' => 'tns:ResponseObject'
        ),
        // mixed $namespace the element namespace for the method or false
        // 'urn:' . $myNamespace,
        $myNamespace,
        // mixed $soapaction the soapaction for the method or false

        $myNamespace . "#getStuffs",
        // mixed $style optional (rpc|document) or false Note: when 'document' is specified, parameter and return wrappers are created for you automatically
        'rpc',
        // mixed $use optional (encoded|literal) or false
        'encoded',
        // string $documentation optional Description to include in WSDL
        'Fetch array of Stuffs ("id", "name").' // documentation
    );

    // $server->wsdl->schemaTargetNamespace = $myNamespace;

    // function def.: nusoap/lib/class.soap_server.php (236)
    $server->service(isset($HTTP_RAW_POST_DATA) ? $HTTP_RAW_POST_DATA : '');

    //   DON'T UNCOMMENT THE FOLLOWING LINES!! - Don't call these headers explicitly,
    //   everything will be handled in function service() appropriately - I know it by experience that it's not a good choice...
    // output:wsdl
    // header('Content-Type: text/xml;charset=utf-8');
    // header('Content-Type: text/xml');
    // echo $server->wsdl->serialize();

    exit(0);

为此文件命名，例如getStuffComplex.php，然后将此文件复制到网络服务器上的某个位置，并记住其路径。
例如，我本地网络服务器上的一个域名是http://soap.local，上面提到的PHP代码可以在http://soap.local/getStuffComplex.php到达。

假设您希望通过SOAP客户端从Visual Studio 2010下的控制台应用程序中调用C＃代码中的getStuffs（）函数。在这种情况下，您必须执行以下步骤：

创建新的控制台应用程序项目
右键单击“参考” - “添加服务参考”
点击“高级...”
点击“添加网络参考...”
粘贴先前保存的PHP文件的URL（包含上面的内容）的路径，并在URL字段中附加“？wsdl”字符串。例如，在我的情况下：http://soap.local/getStuffComplex.php?wsdl
单击绿色右箭头（“Go”）或填写URL字段后按Enter键。如果找到了getStuff（）方法，情况就很有希望了。
在右侧为引用命名（Web引用名称），例如“StuffServiceComplex”（我将在我的代码中使用此名称），而不是按Enter键。现在，您必须在“Web References”
将下面的代码复制到Program.cs中，点击F5或点击绿色的“播放”图标进行测试。

C＃代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Web.Services.Protocols;

namespace WebServiceTestComplex
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                StuffServiceComplex.MyStuffService myService = new StuffServiceComplex.MyStuffService();

                StuffServiceComplex.ResponseObject myRespObject = myService.getStuffs("someone", "1234");

                switch (myRespObject.responseCode)
                {
                    // Everything was OK, results can be output
                    case 1:
                        Console.WriteLine("Everything's OK, let's write the results to the standard output:");
                        foreach (var stuff in myRespObject.stuffArray)
                        {
                            Console.WriteLine("\t"+stuff.id + ".:\t" + stuff.name);
                        }
                        break;
                    // Authentication failed
                    case 2:
                    // Unknown error
                    case 0:
                    default:
                        Console.WriteLine("Error:");
                        Console.WriteLine("\tError code: "+myRespObject.responseCode);
                        Console.WriteLine("\tError message: " + myRespObject.responseMessage);
                        break;
                }

            }
            catch (SoapException e)
            {
                Console.WriteLine("=== SOAP EXCEPTION!! ===");
                Console.WriteLine(e);
            }
            catch (Exception e)
            {
                Console.WriteLine("=== OTHER EXCEPTION!! ===");
                Console.WriteLine(e.ToString());
            }


            Console.WriteLine();
            Console.WriteLine("Press a key...");
            Console.ReadKey();
        }
    }
}

输出：

Everything's OK, let's write the results to the standard output:
        122.:   One stuff
        213.:   Another stuff
        435.:   Whatever stuff
        65.:    Cool Stuff
        92.:    Wow, what a stuff

Press a key...

我希望这可以帮助那些努力将PHP和SOAP和.NET结合在一起的人。

（注意：使用重音符号或任何特殊字母时请注意字符编码。默认情况下，可以使用ANSI（但字符编码必须相同）。）

使用NuSOAP生成WSDL - 返回具有各种类型的结构（int，string，结构数组）
