PHP写webservices接口

在网上找了很多版本，踩了很多的坑

问题主要有两个

1.生成 wsdl文件

2.开启php.ini的配置

生成wsdl需要SoapDiscovery.class.php

我在网上找了一个错误的版本，导致文件有问题

class_name = $class_name;

        $this->service_name = $service_name;

        if(empty($service_url))

        {

            $this->service_url = "http://".$_SERVER['SERVER_NAME'].':'.$_SERVER['SERVER_PORT'].$_SERVER['PHP_SELF'];

        }else{

            $this->service_url = $service_url;

        }

    }



    /**

     * 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 = "\n";

        $headerWSDL.= "service_name\" targetNamespace=\"urn:$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.= "\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();



        $portTypeWSDL = '';

        $bindingWSDL = '\n\n";

        $serviceWSDL = '\n\nservice_name.'Port" binding="tns:'.$this->service_name."Binding\">service_url."\" />\n\n\n";

        $messageWSDL = '';

        foreach ($methods as $method) {

            if ($method->isPublic() && !$method->isConstructor()) {

                $portTypeWSDL.= '\n".'\n
getName()."Response\" />\n\n";

                $bindingWSDL.= '\n".'\nservice_name\" encodingStyle=\"http://schemas.xmlsoap.org/soap/encoding/\" />\n\n
\nservice_name\" encodingStyle=\"http://schemas.xmlsoap.org/soap/encoding/\" />\n
\n\n";

                $messageWSDL.= '\n";

                $parameters = $method->getParameters();

                foreach ($parameters as $parameter) {

                    $messageWSDL.= '\n";

                }

                $messageWSDL.= "\n";

                $messageWSDL.= '\n";

                $messageWSDL.= '\n";

                $messageWSDL.= "\n";

            }

        }

        $portTypeWSDL.= "\n";

        $bindingWSDL.= "\n";

//        return sprintf('%s%s%s%s%s%s', $headerWSDL, $portTypeWSDL, $bindingWSDL, $serviceWSDL, $messageWSDL, '');
        $fso = fopen($this->class_name . ".wsdl" , "w");
        fwrite($fso, sprintf('%s%s%s%s%s%s', $headerWSDL, $portTypeWSDL, $bindingWSDL, $serviceWSDL, $messageWSDL, ''));

    }



    /**

     * SoapDiscovery::getDiscovery() Returns discovery of WSDL.

     *

     * @return string

     **/

    public function getDiscovery() {

        return "\n\nservice_url."?wsdl\" />\n";

    }

}



?>

然后在server.php写上需要的方法

class service
{
  public function HelloWorld()
   {
      return "Hello";
   }
  public  function Add($a,$b)
   {
      return $a+$b;
   }
}

再去访问

creat_wsdl.php

include_once('Service.php');
include_once('SoapDiscovery.class.php');
$wsdl=new SoapDiscovery('Service','soap');//第一参数为类名，也是生成wsdl的文件名Service.wsdl，第二个参数是服务的名字可以随便写
$wsdl->getWSDL();

这个时候就会生成

Service.wsdl

里面有我们写好的方法

再去sevice.php里面加上三行数据

class service
{
  public function HelloWorld()
   {
      return "Hello";
   }
  public  function Add($a,$b)
   {
      return $a+$b;
   }
}
$server=new SoapServer('Service.wsdl',array('soap_version' => SOAP_1_2));
$server->setClass("service");
$server->handle();

最后就是client文件了

header('Content-Type: text/html; charset=UTF-8');
ini_set('soap.wsdl_cache_enabled','0');//关闭缓存
$soap=new SoapClient('http://127.0.0.1/webservices/service.php?wsdl');
echo $soap->Add(1,2);

最后设置php.ini

always_populate_raw_post_data=-1
