PHP编写webservice案例、webservice调用失败
作为开发者来讲,要想写webservice接口或者调用别人的webservice接口,首先需要了解什么是webservice。
简单说, WebService就是一些站点开放一些服务出来, 也可以是你自己开发的Service, 也就是一些方法, 通过URL,指定某一个方法名,发出请求,站点里的这个服务(方法),接到你的请求,根据传过来的参数,做一些处理,然后把处理后的结果以XML形式返回来给你,你的程序就解析这些XML数据,然后显示出来或做其它操作。
在开始编写之前需要对PHP环境做一些配置:
找到 ;extension=PHP_soap.dll ,去掉前面的分号,保存,然后重启apache。
配置好环境就可以编写PHP了,先创建creatService.PHP文件,复制下面代码:
<?PHP class ServiceTest{ public function firstHandle($name){ return 你的名字是:.$name; } public function dbInsert($text){ $db=new MysqLi(localhost,root,,test); if(MysqLi_connect_error()){ return '数据库连接失败。'; exit; } $result=$db->query(insert into test_soap (text) values('.$text.')); if($result){ return $result; }else{ return 插入失败; } } } if(file_exists('ServiceTest.wsdl')){ //只有当ServiceTest.wsdl文件存在时才进行注册类 $objSoapServer = new SoapServer(ServiceTest.wsdl); //注册ServiceTest类的所有方法 $objSoapServer->setClass(ServiceTest); //处理请求 $objSoapServer->handle(); } require_once Soapdiscovery.class.PHP; $dis=new Soapdiscovery(ServiceTest,WebService); //第一个参数为类名也是生成wsdl的文件名 $dis->getWSDL(); ?>
第一次运行creatService.PHP文件时要创建wsdl文件,创建WSDL文件需要用到一个辅助类Soapdiscovery.class.PHP。在文章末尾可以得到。
创建完成之后便是测试调用,创建client.PHP文件,复制以下代码:
ini_set('soap.wsdl_cache_enabled','0');//关闭缓存 $x = new SoapClient(http://localhost/webServiceTest/ServiceTest.wsdl); //这里的链接换成你自己的访问链接 try { echo $x->firstHandle('qweqrwergwe'); echo ('<pre>'); var_dump ( $x->__getFunctions () );//获取服务器上提供的方法 echo ('</pre>'); echo ('<pre>'); var_dump ( $x->__getTypes () );//获取服务器上数据类型 echo ('</pre>'); }catch (SoapFault $f){ echo Error Message: {$f->getMessage()}; }
注意! ini_set('soap.wsdl_cache_enabled','0'); //关闭WSDL缓存
如果不关闭缓存,会造成测试无效,缓存数据会扰乱测试准确性。
注意!如果是在thinkPHP5中使用SoapClient函数应当如下使用:
$client = new \SoapClient ('http://www.baidu.com/ids/terminal/terminalWs.wsdl');
重要点:
使用https访问webservice的话会出现访问异常,博主就遇到这个问题的,本地创建和调用webservice都通过了,但是一放到线上就无法调用了,然后各种google、baidu。最后才发现线上的环境是http强制转了https。
找到httpd-vhost.conf,注释掉一下代码:
## RewriteEngine on ## RewriteCond %{HTTPS} !=on ## RewriteRule ^(.*) https://%{SERVER_NAME}$1 [L,R]
注释掉上面的代码后我发现我的网站不是https了,呜呜呜~,真的是拆了东墙补西墙啊,赶紧想办法,因为网站必须使用https才行,还好我使用的是thinkPHP框架,找到了一个方法,在入口文件index.PHP最下面加入下面的代码就行了:
if (empty($_SERVER['HTTPS']) || $_SERVER['HTTPS'] === off) { $location = 'https://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']; header('HTTP/1.1 301 Moved Permanently'); header('Location: ' . $location); exit; }
