我在this example之后创建了一个PHP RESTful API(底部的代码)。根据我的理解,API通过.htaccess
文件将不存在的URI组件转换为地址中的GET参数,如下所示:
<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>
如果我这样做,例如:
http://mysite/api/v1/endpoint1/param1
可以在API实现中解析 endpoint1/param1
以调用PHP函数endpoint1(param1)
。
现在我的问题是,param1非常长,我希望将AJAX用于POST
param1
,但POST不会通过
例如,对于RESTful API:
http://mysite/api/v1/endpoint1
我使用AJAX发布了data
,如下所示:
$.post('http://mysite/api/v1/endpoint1/',data,callback,'json');
在API.class.php
中,$_SERVER['REQEUEST_METHOD']
为'POST'
,但$_POST
为空数组。
我的问题是:
当我POST
要mod_rewrite
处理虚拟网址时,实际发生了什么。最终结果是GET
请求mode_rewrite
请求或我的AJAX调用请求POST
吗?
如何修改代码以获取POST
ed数据? (是否可以要求mod_rewrite使用POST方法?)
我很困惑,任何指针都很受欢迎。
相关REST api的界面是(API.class.php
,有关完整代码,请参阅the example):
<?php
abstract class API
{
protected $method = '';
protected $endpoint = '';
protected $args = Array();
protected $file = Null;
public function __construct($request) {
header("Access-Control-Allow-Orgin: *");
header("Access-Control-Allow-Methods: *");
header("Content-Type: application/json");
$this->args = explode('/', rtrim($request, '/'));
$this->endpoint = array_shift($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);
$this->args[] = ???; //Problem line: how do I add post to the args
break;
case 'GET':
$this->request = $this->_cleanInputs($_GET);
break;
case 'PUT':
$this->request = $this->_cleanInputs($_GET);
$this->file = file_get_contents("php://input");
break;
default:
$this->_response('Invalid Method', 405);
break;
}
}
public function processAPI() {
if ((int)method_exists($this, $this->endpoint) > 0) {
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 $k => $v) {
$clean_input[$k] = $this->_cleanInputs($v);
}
} else {
$clean_input = trim(strip_tags($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];
}
}
?>
答案 0 :(得分:0)
我相信这是你遇到的问题: Is it possible to redirect post data?
您应该在.htaccess文件中更改此行: RewriteRule api / v1 /(.*)$ api / v1 / api.php?request = $ 1 [QSA,NC,L]
于: RewriteRule api / v1 /(.*)$ api / v1 / api.php?request = $ 1 [QSA,NC,P]
