html页面代码

<form action="api.php" method="get"><input type="text" name="account" /><input type="submit" value="查询" /></form>

从数据库读出结果，将结果输出到页面

<?phprequire_once("mysql_config.php");require_once("mysql_class.php");$account = $_REQUEST['account'];$db = new MYSQL_DB;@$db->connect($dbhost, $dbuser, $dbpw, $dbname);@$tmp = $db->query("SELECT * FROM user WHERE account='$account'");@$row = $db->fetch_array($tmp);$ro = $row;$ro['diqu'] = urlencode($row['diqu']);$ro['sex'] = urlencode($row['sex']);if(empty($row)){echo 0;}else{echo urldecode(json_encode($ro));}?>

负责抓取的php页面

<?php$account = $_REQUEST['account'];$url = "http://192.168.1.100/zx_demo/test_interface3.php?account=$account";$info = file($url);$result = json_decode($info[0],true);echo "ID   ：".$result['messageId']."<br/>";echo "性别：".$result['categoryId']."<br/>";echo "年龄：".$result['userName']."<br/>";echo "地区：".$result['userAddress']."<br/>";echo "备注：".$result['content']."<br/>";echo "电话：".$result['userTel']."<br/>";?>
