还见 webservice ！

09年末做过一次webservice，10年末又做一次webservice，比较两次，意境真不同，记录一下

09年是第一次做所以曲折不断，很怀念去年在兔哥公司的那段日子，PHP用的心潮澎湃、地动山摇。在此感谢网财给我的历练与磨难。

10年这次做算是很顺利，没有什么难度，感觉少了一份释然，作为一名老鸟已没有太多兴奋的情绪，多一点的只是感觉双肩背负的责任更重了一层。新年即将到来，祝大家财源广进、步步高升、儿孙满堂。。。

总结下webservice的实现过程：

第一、写服务端

<?PHP
/**
* 文件名:server.PHP
* 功     能:soap服务端
* 作     者:陈飞
* 日     期:2010年12月21日
*/
session_start();
class DemoServer{

public function conn(){

  $link = MysqL_connect('host','root','password')or die('数据库连接错误!');

  MysqL_select_db('gdwh',$link)or die('数据库不存在!');

  MysqL_query("set names 'gbk'");

}

    /**
     * userstatus
     * @param string $username
     * @return string $username
     * @return string $uid
     * @return string $error
     */
public function userStatus($username){//正确则返回会员的ID；错误则返回-100

  $this->conn();

  $sql = "select uid from user where uname='$username'";

  $result = MysqL_query($sql);

  $row = MysqL_fetch_array($result);

  $uid = $row[0];

  //$error = MysqL_error();

  if($uid != ""){

   return "<?xml version='1.0' encoding='gb2312'?><user><username>$username</username><uid>$uid</uid></user>";

  }else{

   return "<?xml version='1.0' encoding='gb2312'?><user><username>-100</username><uid>-100</uid></user>";
  }


}

/**
* creatComent
* @param string $post
* @param string $username
* @return string $postid
* @return string $error
*/
public function creatComent($post,$username){

  $this->conn();

  if($post=="" or $username==""){

   return "<?xml version='1.0' encoding='gb2312'?><result>-10</result>";
   exit;
  }

  $time = time();

  $insert = "insert into videomainreview (mid,post,uname,creatTime) values ('','$post','$username','$time')";

  $result = MysqL_query($insert);

  if($result){

   $postid = MysqL_insert_id();

   return "<?xml version='1.0' encoding='gb2312'?><postid>$postid</postid>";

  }else{

   return "<?xml version='1.0' encoding='gb2312'?><postid>-20</postid>";

  }

}

}

/*
$user = new DemoServer();
print_r($user->creatComent('测试创建视频主贴的接口是否正常工作!','user0002'));
*/

ini_set("soap.wsdl_cache_enabled","0");//清除缓存
$server = new SoapServer('DemoServer.wsdl',array('soap_version' => SOAP_1_2));//加载soap类
$server->setClass('DemoServer');//设置类名
$server->handle();
?>

第二步：生成wsdl文件

还是用zend studio 6.0，新版的（8.0）试过跟老版本的有些差异，比较麻烦；

file->explort->PHP->wsdl

填好类，服务端PHP 文件的路径，设置完毕ok

<?xml version='1.0' encoding='UTF-8'?>

<deFinitions name="DemoServer" targetNamespace="urn:DemoServer" xmlns:typens="urn:DemoServer" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns="http://schemas.xmlsoap.org/wsdl/">
<message name="conn"/>
<message name="connResponse"/>
<message name="creatComent">
  <part name="post" type="xsd:string"/>
  <part name="username" type="xsd:string"/>
</message>
<message name="creatComentResponse">

</message>
<message name="userStatusResponse">
  <part name="userStatusReturn" type="xsd:string"/>
</message>
<portType name="DemoServerPortType">
  <operation name="conn">
   <input message="typens:conn"/>
   <output message="typens:connResponse"/>
  </operation>
  <operation name="creatComent">
   <documentation>
    creatComent
   </documentation>
   <input message="typens:creatComent"/>
   <output message="typens:creatComentResponse"/>
  </operation>
  <operation name="userStatus">
   <documentation>
    userstatus
   </documentation>
   <input message="typens:userStatus"/>
   <output message="typens:userStatusResponse"/>
  </operation>
</portType>
<binding name="DemoServerBinding" type="typens:DemoServerPortType">
  <soap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http"/>
  <operation name="conn">
   <soap:operation soapAction="urn:DemoServerAction"/>
   <input>
    <soap:body namespace="urn:DemoServer" use="encoded" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>
   </input>
   <output>
    <soap:body namespace="urn:DemoServer" use="encoded" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>
   </output>
  </operation>
  <operation name="creatComent">
   <soap:operation soapAction="urn:DemoServerAction"/>
   <input>
    <soap:body namespace="urn:DemoServer" use="encoded" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>
   </input>
   <output>
    <soap:body namespace="urn:DemoServer" use="encoded" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>
   </output>
  </operation>
  <operation name="userStatus">
   <soap:operation soapAction="urn:DemoServerAction"/>
   <input>
    <soap:body namespace="urn:DemoServer" use="encoded" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>
   </input>
   <output>
    <soap:body namespace="urn:DemoServer" use="encoded" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>
   </output>
  </operation>
</binding>
<service name="DemoServerService">
  <port name="DemoServerPort" binding="typens:DemoServerBinding">
   <soap:address location="http://113.108.192.245:81/gdwh/webserver/gdwh.php"/>
  </port>
</service>
</deFinitions>

第三步：写客户端测试

<?PHP
$client = new SoapClient('http://113.108.192.245:81/gdwh/webserver/DemoServer.wsdl');
array(
"trace"=>1,
"exceptions"=>0,
"soap_version" => SOAP_1_2);
$result = $client->creatComent('thank your test','user0004');
print_r($result);
?>

基本就是这样实现的吧！
