php app接口开发
实例:通过域名+文件名访问接口文件:app_api.com/response.php

1 <?php 2 3 class Response { 4 const JSON = "json"; 5 /** 6 * 按综合方式输出通信数据 7 * @param integer $code 状态码 8 * @param string $message 提示信息 9 * @param array $data 数据 10 * @param string $type 数据类型 11 * return string 12 */ 13 public static function show($code, $message = '', $data = array(), $type = self::JSON) { 14 if(!is_numeric($code)) { 15 return ''; 16 } 17 18 $type = isset($_GET['format']) ? $_GET['format'] : self::JSON; 19 20 $result = array( 21 'code' => $code, 22 'message' => $message, 23 'data' => $data, 24 ); 25 26 if($type == 'json') { 27 self::json($code, $message, $data); 28 exit; 29 } elseif($type == 'array') { 30 var_dump($result); 31 } elseif($type == 'xml') { 32 self::xmlEncode($code, $message, $data); 33 exit; 34 } else { 35 // TODO 36 } 37 } 38 /** 39 * 按json方式输出通信数据 40 * @param integer $code 状态码 41 * @param string $message 提示信息 42 * @param array $data 数据 43 * return string 44 */ 45 public static function json($code, $message = '', $data = array()) { 46 47 if(!is_numeric($code)) { 48 return ''; 49 } 50 51 $result = array( 52 'code' => $code, 53 'message' => $message, 54 'data' => $data 55 ); 56 57 echo json_encode($result); 58 exit; 59 } 60 61 /** 62 * 按xml方式输出通信数据 63 * @param integer $code 状态码 64 * @param string $message 提示信息 65 * @param array $data 数据 66 * return string 67 */ 68 public static function xmlEncode($code, $message, $data = array()) { 69 if(!is_numeric($code)) { 70 return ''; 71 } 72 73 $result = array( 74 'code' => $code, 75 'message' => $message, 76 'data' => $data, 77 ); 78 79 header("Content-Type:text/xml"); 80 $xml = "<?xml version='1.0' encoding='UTF-8'?>\n"; 81 $xml .= "<root>\n"; 82 83 $xml .= self::xmlToEncode($result); 84 85 $xml .= "</root>"; 86 echo $xml; 87 } 88 89 public static function xmlToEncode($data) { 90 91 $xml = $attr = ""; 92 foreach($data as $key => $value) { 93 if(is_numeric($key)) { 94 $attr = " id='{$key}'"; 95 $key = "item"; 96 } 97 $xml .= "<{$key}{$attr}>"; 98 $xml .= is_array($value) ? self::xmlToEncode($value) : $value; 99 $xml .= "</{$key}>\n"; 100 } 101 return $xml; 102 } 103 104 }
在其他文件调用接口文件:test.php,访问test.php app_api.com/test.php

1 <?php 2 require_once("./response.php"); 3 4 $data = array( 5 "name" => "bk", 6 "age" => 25 7 ); 8 9 Response::json(200,"返回成功",$data);
效果
使用xml封装接口方法
综合封装通信方法
