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

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 = - 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);
