webservice有很多优点经常被用来做数据交换一类的工作,php也不甘示弱新版本的php也可以用来开发webservice了。虽然比起java,asp.net开发起来要麻烦一些,下面分享下我用php开发的第一个webservice
1.开发webservice要先打开php_soap.dll扩展库,编辑php.ini文件去前面的分号,之后看看设置生效没有
看到有这个就说明配置成功了,下面就可以接着开发了
2.php发布webservice和java不同,php需要生成一个wsdl文件才能把接口发布出去,如果是zendstudio会方便点。如果没有zendstudio也没关系,下面这个工具类可以生成wsdl文件
class_name = $class_name;
$this->service_name = $service_name;
}
/**
* SoapDiscovery::getWSDL() Returns the WSDL of a class if the class is instantiable.
*
* @return string
**/
public function getWSDL() {
if (empty($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\"> \n \n \n";
$messageWSDL = '';
foreach ($methods as $method) {
if ($method->isPublic() && !$method->isConstructor()) {
$portTypeWSDL.= '\n".'\n \n";
$bindingWSDL.= '\n".' \nservice_name\" encodingStyle=\"http://schemas.xmlsoap.org/soap/encoding/\" />\n\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, ''));
exit;
}
/**
* SoapDiscovery::getDiscovery() Returns discovery of WSDL.
*
* @return string
**/
public function getDiscovery() {
return "\n\n \n ";
}
}
?>
4.借助生成wsdl的工具类和第三步生成的类来生成wsdl,生成wsdl的类也是一个php,命名可以随意我这里命名为StudentWebService,使用下面的代码就能生成wsdl
getWSDL();
?>
5.接下来删除第四步里的php文件里面的内容,改为下面这样
setClass("Student");
//处理请求
$objSoapServer->handle();
?>
6.编写一个客户端来测试webservice接口,如果不会写也可以偷个懒直接使用soapui就行,下面是php的客户端测试类test.php
outputName('蔡依林'));
echo "
";
?>
平时的开发可能是返回一个xml或者json,要真正学好webservice这两块的知识也要很熟练才可以。
