php下webservice使用总结
基于thinkphp3.2的
1.修改php配置 php.ini
extension=php_soap.dll
soap.wsdl_cache_enabled=0
2.soap有两种模式 wsdl和 no-wsdl
（1）wsdl
首先，先生成wsdl文件
生成wsdl的方法
<?php namespace Api\Controller; use Api\Service\SoapDiscovery; use Think\Controller; class CreatewsController extends Controller { public function index() { $disco = new SoapDiscovery('\\Api\\Controller\\ServerController', 'soap'); //第一个参数是类名（生成的wsdl文件就是以它来命名的），即Service类，第二个参数是服务的名字（这个可以随便写）。 $r = $disco->getWSDL(); exit(); } }
ServerController.class.php
<?php namespace Api\Controller; use Think\Controller; class ServerController extends Controller { public function hello1() { return 'hello good'; } public function sum1($a = 0, $b = 1) { return $a + $b; } }
SoapDiscovery.class.php
<?php namespace Api\Service; /** * SoapDiscovery Class that provides Web Service Definition Language (WSDL). * * @package SoapDiscovery * @author Braulio Jos?Solano Rojas * @copyright Copyright (c) 2005 Braulio Jos?Solano Rojas * @version $Id$ * @access public **/ class SoapDiscovery { private $class_name = ''; private $service_name = ''; /** * SoapDiscovery::__construct() SoapDiscovery class Constructor. * * @param string $class_name * @param string $service_name **/ public function __construct($class_name = '', $service_name = '') { $this->class_name = $class_name; $this->service_name = $service_name; } /** * SoapDiscovery::getWSDL() Returns the WSDL of a class if the class is instantiable. * * @return string **/ public function getWSDL() { if (empty($this->service_name)) { throw new Exception('No service name.'); } $headerWSDL = "<?xml version=\"1.0\" ?>\n"; $headerWSDL.= "<definitions name=\"$this->service_name\" targetNamespace=\"urn:$this->service_name\" xmlns:wsdl=\"http://schemas.xmlsoap.org/wsdl/\" xmlns:soap=\"http://schemas.xmlsoap.org/wsdl/soap/\" xmlns:tns=\"urn:$this->service_name\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:SOAP-ENC=\"http://schemas.xmlsoap.org/soap/encoding/\" xmlns=\"http://schemas.xmlsoap.org/wsdl/\">\n"; $headerWSDL.= "<types xmlns=\"http://schemas.xmlsoap.org/wsdl/\" />\n"; if (empty($this->class_name)) { throw new Exception('No class name.'); } $class = new \ReflectionClass($this->class_name); if (!$class->isInstantiable()) { throw new Exception('Class is not instantiable.'); } $methods = $class->getMethods(); $ws_url = '/api/index/ws?wsdl'; $host = 'http://'.$_SERVER['SERVER_NAME'] . ':' . $_SERVER['SERVER_PORT']; $tmp = str_replace('\\', '', dirname($_SERVER['SCRIPT_NAME'])); $tmp = empty($tmp) ? '' : '/' . trim($tmp, '/'); $host .= $tmp; $site = $host.'/index.php'; $ws_url = $site.$ws_url; $portTypeWSDL = '<portType name="'.$this->service_name.'Port">'; $bindingWSDL = '<binding name="'.$this->service_name.'Binding" type="tns:'.$this->service_name."Port\">\n<soap:binding style=\"rpc\" transport=\"http://schemas.xmlsoap.org/soap/http\" />\n"; //$serviceWSDL = '<service name="'.$this->service_name."\">\n<documentation />\n<port name=\"".$this->service_name.'Port" binding="tns:'.$this->service_name."Binding\"><soap:address location=\"http://".$_SERVER['SERVER_NAME'].':'.$_SERVER['SERVER_PORT'].$_SERVER['PHP_SELF']."\" />\n</port>\n</service>\n"; $serviceWSDL = '<service name="'.$this->service_name."\">\n<documentation />\n<port name=\"".$this->service_name.'Port" binding="tns:'.$this->service_name."Binding\"><soap:address location=\"{$ws_url}\" />\n</port>\n</service>\n"; $messageWSDL = ''; foreach ($methods as $method) { if ($method->isPublic() && !$method->isConstructor()) { $portTypeWSDL.= '<operation name="'.$method->getName()."\">\n".'<input message="tns:'.$method->getName()."Request\" />\n<output message=\"tns:".$method->getName()."Response\" />\n</operation>\n"; $bindingWSDL.= '<operation name="'.$method->getName()."\">\n".'<soap:operation soapAction="urn:'.$this->service_name.'#'.$this->class_name.'#'.$method->getName()."\" />\n<input><soap:body use=\"encoded\" namespace=\"urn:$this->service_name\" encodingStyle=\"http://schemas.xmlsoap.org/soap/encoding/\" />\n</input>\n<output>\n<soap:body use=\"encoded\" namespace=\"urn:$this->service_name\" encodingStyle=\"http://schemas.xmlsoap.org/soap/encoding/\" />\n</output>\n</operation>\n"; $messageWSDL.= '<message name="'.$method->getName()."Request\">\n"; $parameters = $method->getParameters(); foreach ($parameters as $parameter) { $messageWSDL.= '<part name="'.$parameter->getName()."\" type=\"xsd:string\" />\n"; } $messageWSDL.= "</message>\n"; $messageWSDL.= '<message name="'.$method->getName()."Response\">\n"; $messageWSDL.= '<part name="'.$method->getName()."\" type=\"xsd:string\" />\n"; $messageWSDL.= "</message>\n"; } } $portTypeWSDL.= "</portType>\n"; $bindingWSDL.= "</binding>\n"; //return sprintf('%s%s%s%s%s%s', $headerWSDL, $portTypeWSDL, $bindingWSDL, $serviceWSDL, $messageWSDL, '</definitions>'); $fso = fopen(dirname(__FILE__) . "/SoapService.wsdl", "w"); fwrite($fso, sprintf('%s%s%s%s%s%s', $headerWSDL, $portTypeWSDL, $bindingWSDL, $serviceWSDL, $messageWSDL, '</definitions>')); } /** * SoapDiscovery::getDiscovery() Returns discovery of WSDL. * * @return string **/ public function getDiscovery() { return "<?xml version=\"1.0\" ?>\n<disco:discovery xmlns:disco=\"http://schemas.xmlsoap.org/disco/\" xmlns:scl=\"http://schemas.xmlsoap.org/disco/scl/\">\n<scl:contractRef ref=\"http://".$_SERVER['SERVER_NAME'].':'.$_SERVER['SERVER_PORT'].$_SERVER['PHP_SELF']."?wsdl\" />\n</disco:discovery>"; } }
server端
<?php namespace Api\Controller; use Think\Controller; class IndexController extends Controller {public function ws() { ob_clean(); $server = new \SoapServer(dirname(dirname(dirname(__FILE__))) . '/\Api\Service\SoapService.wsdl', array('soap_version' => SOAP_1_2, 'trace' => true, 'exceptions' => true)); $server->setClass('\Api\Controller\ServerController'); //注册ServerController类的所有方法 $server->handle(); //处理请求 } }
client端
<?php namespace Api\Controller; use Think\Controller; class IndexController extends Controller { public function testWsdl() { try { $soap = new \SoapClient("http://127.0.0.102:80/index.php/api/index/ws?wsdl", array( 'soap_version' => SOAP_1_2, 'cache_wsdl' => WSDL_CACHE_NONE, )); echo $soap->sum1(12, 2); } catch (Exction $e) { echo print_r($e->getMessage(), true); } } }
（2）no-wsdl
server
<?php namespace Api\Controller; use Think\Controller; class IndexController extends Controller { public function ws() { ob_clean(); $arr = array('uri' => "abc"); $server = new \SoapServer(null, $arr); $server->setClass('\Api\Controller\ServerController'); //注册Service类的所有方法 $server->handle(); //处理请求 exit(); } }
client
<?php namespace Api\Controller; use Think\Controller; class IndexController extends Controller { public function testNonWsdl() { try { $soap = new \SoapClient(null, array( "location" => "http://127.0.0.102:80/index.php/api/index/ws", "uri" => "abc", //资源描述符服务器和客户端必须对应 "style" => SOAP_RPC, "use" => SOAP_ENCODED, )); echo $soap->sum1(12, 2); } catch (Exction $e) { echo print_r($e->getMessage(), true); } } }
目录结构
补充：
1. 报错looks like we got no XML document in
（1）
php.ini中的 always_populate_raw_post_data = -1 注释去掉
（2）服务器端代码出错，只要有错，就会报上面的提示，仔细检查服务器端代码语法问题即可解决
（3）确保服务器端没有任何输出
2.偶尔出现 Warning: SoapClient::SoapClient(): I/O warning : failed to load external entity
在网上查找资料看到
PHP程序作为 SOAP客户端 采用 WSDL 模式访问远端服务器的时候，PHP是通过调用 libcurl 实现的。至少在 PHP5.2.X 是这样的
如果采用 non-WSDL 模式，就不需要 libcurl。除了 了ibcurl以外，至少还关联的库包括：libidn,ibgcc,libiconv,libintl,openssl
但是我改成non-WSDL也没解决问题
最后发现是，增加xml转化的函数里，增加了libxml_disable_entity_loader(true);
所以才会出现，第一次调用成功，发送普通的字符串也没问题，只有发送xml数据才会出现错误
3.输出需要请求的方法和携带的参数（适用于wsdl的形式）
try { $client = new \SoapClient(''http://127.0.0.102:80/index.php/api/index/ws?wsdl, array( 'soap_version' => SOAP_1_2, 'cache_wsdl' => WSDL_CACHE_NONE, )); echo 'SOAP types'; var_dump($client->__getTypes()); echo 'SOAP Functions'; var_dump($client->__getFunctions()); } catch (Exction $e) { echo print_r($e->getMessage(), true); }
4. 调用.net service方法必须传入命名参数；而调用php web服务方法，一定不能传入命名参数，只能按顺序传入
调用net的webservice
$params = [ 'strXml'=>$xml_data, 'strType'=>$sType ]; $result = $client->HandleBIMInfo($params);
调用php的webservice
$result = $client->HandleBIMInfo($xml_data, $sType);
