php文件:test.php 是通用通信类

 

<?phpclass Response {	const JSON = "json";	/**	* 按综合方式输出通信数据	* @param integer $code 状态码	* @param string $message 提示信息	* @param array $data 数据	* @param string $type 数据类型	* return string	*/	public static function show($code, $message = '', $data = array(), $type = self::JSON) {		if(!is_numeric($code)) {			return '';		}		$type = isset($_GET['format']) ? $_GET['format'] : self::JSON;		$result = array(			'code' => $code,			'message' => $message,			'data' => $data,		);		if($type == 'json') {			self::json($code, $message, $data);			exit;		} elseif($type == 'array') {			var_dump($result);		} elseif($type == 'xml') {			self::xmlEncode($code, $message, $data);			exit;		} else {			// TODO		}	}	/**	* 按json方式输出通信数据	* @param integer $code 状态码	* @param string $message 提示信息	* @param array $data 数据	* return string	*/	public static function json($code, $message = '', $data = array()) {				if(!is_numeric($code)) {			return '';		}		$result = array(			'code' => $code,			'message' => $message,			'data' => $data		);		echo json_encode($result);		exit;	}	/**	* 按xml方式输出通信数据	* @param integer $code 状态码	* @param string $message 提示信息	* @param array $data 数据	* return string	*/	public static function xmlEncode($code, $message, $data = array()) {		if(!is_numeric($code)) {			return '';		}		$result = array(			'code' => $code,			'message' => $message,			'data' => $data,		);		header("Content-Type:text/xml");		$xml = "<?xml version='1.0' encoding='UTF-8'?>\n";		$xml .= "<root>\n";		$xml .= self::xmlToEncode($result);		$xml .= "</root>";		echo $xml;	}	public static function xmlToEncode($data) {		$xml = $attr = "";		foreach($data as $key => $value) {			if(is_numeric($key)) {				$attr = " id='{$key}'";				$key = "item";			}			$xml .= "";			$xml .= is_array($value) ? self::xmlToEncode($value) : $value;			$xml .= "{$key}>\n";		}		return $xml;	}}

testxml&json.php通过调用test类的show()方法实现了生成xml和json


<?phprequire_once ('./test.php');$data=array('id'=>1,'name'=>"david");Response::show(200,'success',$data);


这样app开发工程师就可以通过给show()函数最后一个参数赋不同值,选择要生成xml数据还是json数据。

通过http请求的get请求的参数:

http://localhost/testxml&json.php?format=xml  这是要生成xml的url

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
