[英]Unable to capture WooCommerce REST API request which is causing PHP error
[英]Creating a Rest API in PHP causing a redirect error
我正在嘗試在PHP中創建適當的RESTful API。 我一直在遵循http://coreymaynard.com/blog/creating-a-restful-api-with-php/中的一些步驟,對我來說,除了我嘗試去時,我似乎做的所有事情都完全一樣到http:// localhost / api / v1 / example我收到內部服務器錯誤。
在apache錯誤日志中,我看到以下內容:
[Sat Feb 18 19:30:10.594193 2017] [core:error] [pid 10272:tid 1144] [client ::1:58203] AH00124: Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace.

我的BaseAPI類(在示例中稱為API)如下:
abstract class API
{
protected $method = '';
protected $endpoint = '';
protected $verb = '';
protected $args = Array();
public function __construct($request)
{
header("Access-Control-Allow-Origin: *");
header("Access-Control-Allow-Method: *");
header("Content-Type: application/json");
$this->args = explode('/', rtrim($request, '/'));
$this->endpoint = array_shift($this->args);
if (array_key_exists(0, $this->args) && !is_numeric($this->args[0]))
{
$this->verb = array_shift($this->args);
}
$this->method = $_SERVER["REQUEST_METHOD"];
if ($this->method === "POST" && array_key_exists('HTTP_X_HTTP_METHOD', $_SERVER))
{
if ($_SERVER['HTTP_X_HTTP_METHOD'] === "DELETE")
{
$this->method = "DELETE";
}
else if ($_SERVER["HTTP_X_HTTP_METHOD"] === "PUT")
{
$this->method = "PUT";
}
else
{
throw new Exception("Unexpected header");
}
}
switch ($this->method)
{
case 'DELETE':
case 'POST':
$this->request = $this->cleanInputs($_POST);
break;
case 'GET':
$this->request = $this->cleanInputs($_GET);
break;
case 'PUT':
$this->request = $this->clearInputs($_GET);
$this->file = file_get_contents("php://input");
break;
default:
$this->response('Invalid Method', 405);
break;
}
}
public function processAPI()
{
if (method_exists($this, $this->endpoint))
{
return $this->response($this->{$this->endpoint}($this->args));
}
return $this->response("No Endpoint: $this->endpoint", 404);
}
private function response($data, $status = 200)
{
header("HTTP/1.1 " . $status . " " . $this->requestStatus($status));
return json_encode($data);
}
private function cleanInputs($data)
{
$clean_input = Array();
if (is_array($data))
{
foreach ($data as $key => $value)
{
$clean_input[$key] = $this->cleanInputs($value);
}
}
else
{
$clean_input = htmlspecialchars($data);
}
return $clean_input;
}
private function requestStatus($code)
{
$status = array(
200 => 'OK',
404 => 'Not Found',
405 => 'Method Not Allowed',
500 => 'Internal Server Error'
);
return ($status[$code])?$status[$code]:$status[500];
}
}
MyAPI文件如下:
require_once 'BaseApi.php';
class MyAPI extends API
{
public function __construct($request)
{
parent::__construct($request);
}
protected function example()
{
if ($this->method === "GET")
{
return "Hello to my RESTful API";
}
else
{
return "Only accepts GET requests";
}
}
}
我的api.php如下:
require_once 'MyAPI.php';
try
{
$api = new MyAPI($_REQUEST['request']);
echo $api->processAPI();
}
catch (Exception $ex)
{
echo $ex->getMessage();
}
我的.htaccess文件如下:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule api/v1/(.*)$ api/v1/api.php?request=$1 [QSA,NC,L]
</IfModule>
在我看來,一切都與該文章中的內容完全相同,如果有什么不同,我使用的是在Windows 10上運行的Wamp服務器。
我懷疑,所有文件.htaccess
和*.php
位於同一基本目錄中。
在這種情況下,替換api/v1/api.php
將被視為對不存在文件的另一個請求,因為api.php
在當前目錄中,而不在api/v1
。
因此, api/v1/example
將被重寫為api/v1/api.php?request=example
,然后被重寫為api/v1/api.php?request=api.php
,然后被重寫為api/v1/api.php?request=api.php
等。
要使其工作,必須在基本目錄中具有.htaccess
,並且在子目錄api/v1
必須具有所有PHP文件。
如果要將文件保留在一個目錄中,則重寫規則的目標必須指向現有的腳本文件api.php?request=$1
,例如
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule api/v1/(.*)$ api.php?request=$1 [QSA,NC,L]
