php开发安卓服务器之 php封装json xml通用app数据通信接口
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

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
