浅谈PHP调用Webservice思路及源码分享
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';
