PHP SOAP终于测验成功
PHP5已经支持soap了。可是不知怎么回事,网上的例子在我机器上总是通过不了。今天终于调通了,高兴!
PHP的SOAP很简单,首先建立一个函数文件soapfunc.php,这个文件包含了我们想通过SOAP协议暴露给Web services的函数:reverse,add2numbers和gettime,没有什么不同,就是普通的php函数,前两个就是网上到处都可以看到的,我自己又加了一个。这里,一定要注意规范php代码的格式,我的问题就是出在格式上了。
--------------------------------------------------------------------------------
<?php function reverse($str){ $retval = ''; if(strlen($str) < 1) { return new SoapFault('Client','','Invalid string'); } for ($i = 1; $i <= strlen($str); $i++) { $retval .= $str[(strlen($str) - $i)]; } return $retval; } function add2numbers($num1, $num2) { if (trim($num1) != intval($num1)) { return new SoapFault('Client','','The first number is invalid'); } if (trim($num2) != intval($num2)) { return new SoapFault('Client','','The second number is invalid'); } return ($num1 + $num2); } function gettime(){ $time=strftime("%Y-%m-%d %H:%M:%S"); return $time; } ?>
--------------------------------------------------------------------------------
然后,编写soapserver.php,这个文件首先创建一个SoapServer对象实例,然后将我们要暴露的函数注册,最后的handle()用来处理接受到的SOAP请求。网上好多代码里面都没有这一行。
--------------------------------------------------------------------------------
<? include_once('soapfunc.php'); $soap = new SoapServer(null,array('uri'=>"http://test-uri/")); $soap->addFunction('reverse'); $soap->addFunction('add2numbers'); $soap->addFunction('gettime'); $soap->addFunction(SOAP_FUNCTIONS_ALL); $soap->handle(); ?>
--------------------------------------------------------------------------------
最后,我们需要一个测试页面,来测一下我们的Web Service是否好用,soapclient.php
--------------------------------------------------------------------------------
<? try { $client = new SoapClient(null, array('location' => "http://localhost/phpsite/soap/soapserver.php",'uri' => "http://test-uri/")); $str = "This string will be reversed"; $reversed = $client->reverse($str); echo "If you reverse '",$str,"', you get '",$reversed,"'"; $n1=20; $n2=33; $sum = $client->add2numbers($n1,$n2); echo "If you try ",$n1,"+",$n2,", you will get ",$sum,""; echo "The system time is: ",$client->gettime(); } catch (SoapFault $fault){ echo "Fault! code:",$fault->faultcode,", string: ",$fault->faultstring; } ?>
--------------------------------------------------------------------------------
测试页面首先创建一个SoapClient的实例,指定了该服务的URL和URI,SoapClient的构造函数第一个参数本应是指定WSDL(描述Web服务的公共接口)描述文件的,本来我也没看过WSDL的写法,所以就不采用wsdl方式定义了。
创建完SoapClient以后,就可以像本地函数一样调用Web Services了。
