php下webservice使用总结详解编程语言

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 sum1($a = 0, $b = 1)

server端

        $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

        } catch (Exction $e) { 
            echo print_r($e->getMessage(), true); 
        } 
    } 
}

use Think/Controller; 
class IndexController extends Controller 
{ 
    public function ws() 
    { 
        ob_clean();

                "style"    => SOAP_RPC, 
                "use"      => SOAP_ENCODED, 
            ));

        } catch (Exction $e) {

        } 
    } 
}

目录结构

php下webservice使用总结详解编程语言

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);
