php webservice

方法一:直接调用

复制代码 代码如下:


 
/******************************************************************************/
/*  文件名 : soapclient.php
/*  说  明 : WebService接口客户端例程
/******************************************************************************/
include('NuSoap.php'); 

// 创建一个soapclient对象,参数是server的WSDL  
$client = new soapclient('http://localhost/Webservices/Service.asmx?WSDL', 'wsdl'); 

// 参数转为数组形式传递 
$aryPara = array('strUsername'=>'username', 'strPassword'=>MD5('password')); 

// 调用远程函数 
$aryResult = $client->call('login',$aryPara); 

//echo $client->debug_str; 
/*
if (!$err=$client->getError()) {
  print_r($aryResult); 
} else { 
  print "ERROR: $err"; 
}
*/

$document=$client->document; 
echo  
  
    
   $document
    
 
 
SoapDocument; 

?> 

复制代码 代码如下:



/******************************************************************************/
/*  文件名 : soapclient.php
/*  说  明 : WebService接口客户端例程
/******************************************************************************/
include('NuSoap.php');

// 创建一个soapclient对象,参数是server的WSDL
$client = new soapclient('http://localhost/Webservices/Service.asmx?WSDL', 'wsdl');

// 参数转为数组形式传递
$aryPara = array('strUsername'=>'username', 'strPassword'=>MD5('password'));

// 调用远程函数
$aryResult = $client->call('login',$aryPara);

//echo $client->debug_str;
/*
if (!$err=$client->getError()) {
  print_r($aryResult);
} else {
  print "ERROR: $err";
}
*/

$document=$client->document;
echo
 
  
   $document
  
 

SoapDocument;

?>

方法二:代理方式调用

复制代码 代码如下:


 
/******************************************************************************/
/*  文件名 : soapclient.php
/*  说  明 : WebService接口客户端例程
/******************************************************************************/
require('NuSoap.php');  

//创建一个soapclient对象,参数是server的WSDL  
$client=new soapclient('http://localhost/Webservices/Service.asmx?WSDL', 'wsdl');  

//生成proxy类  
$proxy=$client->getProxy();  

//调用远程函数  
$aryResult=$proxy->login('username',MD5('password')); 

//echo $client->debug_str; 
/*
if (!$err=$proxy->getError()) {
  print_r($aryResult); 
} else { 
  print "ERROR: $err"; 
}
*/

$document=$proxy->document; 
echo  
  
    
   $document
    
 
 
SoapDocument; 

?> 

复制代码 代码如下:



/******************************************************************************/
/*  文件名 : soapclient.php
/*  说  明 : WebService接口客户端例程
/******************************************************************************/
require('NuSoap.php');

//创建一个soapclient对象,参数是server的WSDL
$client=new soapclient('http://localhost/Webservices/Service.asmx?WSDL', 'wsdl');

//生成proxy类
$proxy=$client->getProxy();

//调用远程函数
$aryResult=$proxy->login('username',MD5('password'));

//echo $client->debug_str;
/*
if (!$err=$proxy->getError()) {
  print_r($aryResult);
} else {
  print "ERROR: $err";
}
*/

$document=$proxy->document;
echo
 
  
   $document
  
 

SoapDocument;
?>

  许多使用NuSoap 调用.NET WebService或J2EE  WebService的朋友可能都遇到过中文乱码问题,下面介绍这一问题的出现的原因和相应的解决方法。
  NuSoap调用WebService出现乱码的原因:
  通常我们进行WebService开发时都是用的UTF-8编码,这时我们需要设置:

复制代码 代码如下:


$client->soap_defencoding = 'utf-8';
$client->soap_defencoding = 'utf-8';

  同时,需要让xml以同样的编码方式传递:

复制代码 代码如下:


$client->xml_encoding = 'utf-8';
$client->xml_encoding = 'utf-8';


  至此应该是一切正常了才对,但是我们在输出结果的时候,却发现返回的是乱码。
  NuSoap调用WebService出现乱码的解决方法:
  实际上,开启了调试功能的朋友,相信会发现$client->response返回的是正确的结果,为什么$result = $client->call($action, array('parameters' => $param)); 却是乱码呢?
  研究过NuSoap代码后我们会发现,当xml_encoding设置为UTF-8时,NuSoap会检测decode_utf8的设置,如果为true,会执行 PHP 里面的utf8_decode函数,而NuSoap默认为true,因此,我们需要设置:

复制代码 代码如下:


$client->soap_defencoding = 'utf-8'; 
$client->decode_utf8 = false; 
$client->xml_encoding = 'utf-8';
$client->soap_defencoding = 'utf-8';
$client->decode_utf8 = false;
$client->xml_encoding = 'utf-8';
