本文介绍了来自PHP的ConsumeWCF服务的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我已经创建了WCF服务项目。我可以使用.NET框架。我可以传递一个变量，并且可以在使用PHP时获取返回变量。但是当我将类对象从PHP传递给服务时，我无法使用该服务。



Iservice.cs

< pre lang =C＃> 命名空间 WCFTest
{
// 注意：您可以使用重构菜单上的重命名命令在代码和配置文件中一起更改接口名称IService1。
[ServiceContract ]
public interface IService1
{
[OperationContract]
string getVal（Student [] st）;

[OperationContract]
string PassMember（CompMember cmp）;
}

public class ALSubjects
{
string SID;
string SName;
string sResult;

public string SubID
{
get { return SID; }
set {SID = value ; }
}

public string SubName
{
get { return SName; }
set {SName = value ; }
}

public string SubResult
{
get { return sResult; }
set {sResult = value ; }
}
}

public class 学生
{
string stID;
string stName;
int stAge;
ALSubjects [] Als = new ALSubjects [] { new ALSubjects（）};

public string StudID
{
get { return stID; }
set {stID = value ; }
}

public string StudName
{
get { return stName; }
set {stName = value ; }
}

public int studAge
{
get { return stAge; }
set {stAge = value ; }
}

public ALSubjects [] Alsubject
{
获取 {返回 Als; }
set {Als = value ; }
}
}

public class CompMember
{
string MemID;
string MemName;
int MemAge;

public string MemberID
{
get { return MemID; }
set {MemID = value ; }
}

public string MemberName
{
get { return MemName; }
set {MemName = value ; }
}

public int MemberAge
{
get { return MemAge; }
set {MemAge = value ; }
}
}
}

} 
} 
  //   t = st [0] .StudName;  
t = st [ 0 ] .Alsubject [ 0 ]。子ID; 
  return  t; 
} 
 
  public   string  PassMember（CompMember mem）
 {
 CompMember cmp =  new  CompMember（）; 
 
 cmp.MemberID = mem.MemberID; 
 cmp.MemberName = mem.MemberName;

  string  j =  您输入： + cmp.MemberID +  ： + cmp.MemberName +  ： + cmp.MemberAge.ToString（）;

这是用于调用WCF服务的PHP代码

 <？php  
 
 try {
  $ client  =  new  SoapClient（  HTTP：//本地主机：1236 /网站/ Service.svc WSDL）; 
 
  //  设置参数 
 $ parms ['  CompMember'] ['  MemberAge'] = ' 会员名称; 
 $ parms ['  CompMember'] [ '  MemberID'] =   123 ; 
 $ parms ['  CompMember'] [ 'MemberName']= 25; 
 
  //  调用Web服务PassMember methordd  
  $ webService  = $ client-> PassMember($parms); 
  $wsResult = $webService->PassMemberResult(); 
   
 // print response 
  print_r($wsResult); 
         
        } catch (Exception $e) { 
        echo 'Caught exception:',  $e->getMessage(), \"\n\"; 
 }   
 // ----------------------------------------------------- 
  
 try{ 
   $client = new SoapClient(\"http://localhost:1236/WebSite/Service.svc?wsdl\"); 
   
  
  
 // Set parameters 
 $parms['Student']['Alsubject']['SubID']  = 'AL002'; 
 $parms['Student']['Alsubject']['SubName']  = 'MATHS'; 
 $parms['Student']['Alsubject']['SubResult']  = 'A'; 
 $parms['Student']['StudID'] =\"123\"; 
 $parms['Student'] ['StudName']= 'Student Name'; 
 $parms['Student'] ['studAge']= 25; 
 
  //  调用Web服务PassMember methordd  
  $ webService  = $ client-> getVal($parms); 
  $wsResult = $webService->getValResult(); 
   
 // print response 
  print_r($wsResult); 
         
        } catch (Exception $e) { 
        echo 'Caught exception:',  $e->getMessage(), \"\n\"; 
 } 
 ?>





When we call service via PHP We have exception

\"Caught exception: Object reference not set to an instance of an object.\"



If someone know solve this problem Please let me know.

Thanks,

Chamara.

解决方案

client = new SoapClient(\"http://localhost:1236/WebSite/Service.svc?wsdl\");

// Set parameters


parms['CompMember']['MemberAge'] = 'Member Name';


parms['CompMember']['MemberID'] =\"123\";


I have create WCF service Project. I can consume from .NET framework. I can pass a variable and can get return variable while consume from PHP. But I cannot consume that service when pass class object to service from PHP.

This is PHP code which used to call WCF service

<?php

  $client = new SoapClient("http://localhost:1236/WebSite/Service.svc?wsdl");

// Set parameters
$parms['CompMember']['MemberAge'] = 'Member Name';
$parms['CompMember']['MemberID'] ="123";
$parms['CompMember'] ['MemberName']= 25;

// Call web service PassMember methordd
 $webService = $client-> PassMember($parms);
 $wsResult = $webService->PassMemberResult();

try{
  $client = new SoapClient("http://localhost:1236/WebSite/Service.svc?wsdl");
 


// Set parameters
$parms['Student']['Alsubject']['SubID']  = 'AL002';
$parms['Student']['Alsubject']['SubName']  = 'MATHS';
$parms['Student']['Alsubject']['SubResult']  = 'A';
$parms['Student']['StudID'] ="123";
$parms['Student'] ['StudName']= 'Student Name';
$parms['Student'] ['studAge']= 25;

// Call web service PassMember methordd
 $webService = $client-> getVal($parms);
 $wsResult = $webService->getValResult();
 
// print response
 print_r($wsResult);
       
       } catch (Exception $e) {
       echo 'Caught exception:',  $e->getMessage(), "\n";
}
?>



When we call service via PHP We have exception
"Caught exception: Object reference not set to an instance of an object."

If someone know solve this problem Please let me know.
Thanks,

解决方案

client = new SoapClient("http://localhost:1236/WebSite/Service.svc?wsdl"); // Set parameters


parms['CompMember']['MemberAge'] = 'Member Name';


parms['CompMember']['MemberID'] ="123";
