我想创建一个 API 来访问我们使用的 MySQL 数据库中有关图书馆顾客和书籍的信息
它基于 CRUD 示例，除了 GET 之外的所有内容都已删除
所以我有 4 个文件：
db_pdo_mysql.php其中包含函数
index.php调用类
book.php包含书籍类
patron.php包含赞助
人类在 index.php 文件中，我将这些类称为：
require_once '../../restler/restler.php';
spl_autoload_register('spl_autoload');
$r = new Restler();
$r->addAPIClass('book');
$r->addAPIClass('patron');
$r->handle();
书.php：
<?php
class book {
public $dp;
function __construct(){
/**
* $this->dp = new DB_PDO_Sqlite();
* $this->dp = new DB_PDO_MySQL();
* $this->dp = new DB_Serialized_File();
*/
$this->dp = new DB_PDO_MySQL();
}
function get($id=NULL) {
return is_null($id) ? $this->dp->getAll() : $this->dp->book($id);
}
}
}
?>
赞助人.php：
<?php
class patron {
public $dp;
function __construct(){
/**
* $this->dp = new DB_PDO_Sqlite();
* $this->dp = new DB_PDO_MySQL();
* $this->dp = new DB_Serialized_File();
*/
$this->dp = new DB_PDO_MySQL();
}
function get($id=NULL) {
return is_null($id) ? $this->dp->getAll() : $this->dp->patron($id);
}
}
?>
和 db_pdo_mysql.php
<?php
class DB_PDO_MySQL
{
private $db;
function __construct ()
{
try {
//update the dbname username and password to suit your server
$this->db = new PDO(
'mysql:host=[HOST REMOVED];dbname=[DATABASE REMOVED]', '[USERNAME REMOVED]', '[PASSWORD REMOVED]');
$this->db->setAttribute(PDO::ATTR_DEFAULT_FETCH_MODE,
PDO::FETCH_ASSOC);
} catch (PDOException $e) {
throw new RestException(501, 'MySQL: ' . $e->getMessage());
}
}
function patron ($id)
{
$this->db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
try {
$sql = 'SELECT * FROM patrons WHERE code = ' . mysql_escape_string(
$id);
return $this->id2int($this->db->query($sql)
->fetch());
} catch (PDOException $e) {
throw new RestException(501, 'MySQL: ' . $e->getMessage());
}
}
function book ($id)
{
$this->db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
try {
$sql = 'SELECT * FROM books WHERE barcode = ' . mysql_escape_string(
$id);
return $this->id2intBooks($this->db->query($sql)
->fetch());
} catch (PDOException $e) {
throw new RestException(501, 'MySQL: ' . $e->getMessage());
}
}
function getAll ()
{
$this->db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
try {
$stmt = $this->db->query('SELECT * FROM patrons');
return $this->id2int($stmt->fetchAll());
} catch (PDOException $e) {
throw new RestException(501, 'MySQL: ' . $e->getMessage());
}
}
private function id2int ($r)
{
if (is_array($r)) {
if (isset($r['code'])) {
$r['code'] = intval($r['code']);
} else {
foreach ($r as $a) {
$a['code'] = intval($a['code']);
}
}
}
return $r;
}
private function id2intBooks ($r)
{
if (is_array($r)) {
if (isset($r['barcode'])) {
$r['barcode'] = intval($r['barcode']);
} else {
foreach ($r as $a) {
$a['barcode'] = intval($a['barcode']);
}
}
}
return $r;
}
}
?>
我使用[domain]/api/test/index.php/patron/[patron id]和[domain]/api/test/index.php/book/[book id]访问数据。
我很困扰！
