Handling PUT/DELETE arguments in PHP
提问by Phil Sturgeon
I am working on my REST client library for CodeIgniterand I am struggling to work out how to send PUT and DELETE arguments in PHP.
我正在为 CodeIgniter开发我的REST 客户端库，我正在努力研究如何在 PHP 中发送 PUT 和 DELETE 参数。
In a few places I have seen people using the options:
在一些地方，我看到人们使用这些选项：
$this->option(CURLOPT_PUT, TRUE);
$this->option(CURLOPT_POSTFIELDS, $params);
Annoyingly, this seems to do nothing. Is this the correct way to set PUT parameters?
令人讨厌的是，这似乎没有任何作用。这是设置 PUT 参数的正确方法吗？
If so, how do I set DELETE parameters?
如果是这样，我如何设置 DELETE 参数？
$this->option() is part of my library, it simply builds up an array of CURLOPT_XX constants and sends them to curl_setopt_array() when the built up cURL request is executed.
$this->option() 是我的库的一部分，它只是构建一个 CURLOPT_XX 常量数组，并在执行构建的 cURL 请求时将它们发送到 curl_setopt_array()。
I am attempting to read PUT and DELETE parameters using the following code:
我正在尝试使用以下代码读取 PUT 和 DELETE 参数：
case 'put':
// Set up out PUT variables
parse_str(file_get_contents('php://input'), $this->_put_args);
break;
case 'delete':
// Set up out PUT variables
parse_str(file_get_contents('php://input'), $this->_delete_args);
break;
There are two options here, I am approaching this in the wrong way or there is a bug somewhere in my libraries. If you could let me know if this should theoretically work I can just hammer away on debug until I solve it.
这里有两个选项，我以错误的方式处理这个问题，或者我的库中某处存在错误。如果你能让我知道这在理论上是否可行，我可以在调试之前进行调试，直到我解决它。
I dont want to waste any more time on an approach that is fundamentally wrong.
我不想再浪费时间在一种根本错误的方法上。

Instead of using CURLOPT_PUT = TRUEuse CURLOPT_CUSTOMREQUEST = 'PUT'and CURLOPT_CUSTOMREQUEST = 'DELETE'then just set values with CURLOPT_POSTFIELDS.
而不是使用CURLOPT_PUT = TRUE用途CURLOPT_CUSTOMREQUEST = 'PUT'和CURLOPT_CUSTOMREQUEST = 'DELETE'然后只设置值时CURLOPT_POSTFIELDS。

Here is some code which may be helpful for others wanting to handle PUT and DELETE params. You are able to set $_PUTand $_DELETEvia $GLOBALS[], but they will not be directly accessible in functions unless declared globalor accessed via $GLOBALS[]. To get around this, I've made a simple class for reading GET/POST/PUT/DELETE request arguments. This also populates $_REQUESTwith PUT/DELETE params.
这里有一些代码可能对其他想要处理 PUT 和 DELETE 参数的人有帮助。您可以设置$_PUT和$_DELETEvia $GLOBALS[]，但除非global通过声明或访问它们，否则它们将无法在函数中直接访问$GLOBALS[]。为了解决这个问题，我创建了一个简单的类来读取 GET/POST/PUT/DELETE 请求参数。这也填充$_REQUEST了 PUT/DELETE 参数。
This class will parse the PUT/DELETE params and support GET/POST as well.
此类将解析 PUT/DELETE 参数并支持 GET/POST。
class Params {
private $params = Array();
public function __construct() {
$this->_parseParams();
}
/**
* @brief Lookup request params
* @param string $name Name of the argument to lookup
* @param mixed $default Default value to return if argument is missing
* @returns The value from the GET/POST/PUT/DELETE value, or $default if not set
*/
public function get($name, $default = null) {
if (isset($this->params[$name])) {
return $this->params[$name];
} else {
return $default;
}
}
private function _parseParams() {
$method = $_SERVER['REQUEST_METHOD'];
if ($method == "PUT" || $method == "DELETE") {
parse_str(file_get_contents('php://input'), $this->params);
$GLOBALS["_{$method}"] = $this->params;
// Add these request vars into _REQUEST, mimicing default behavior, PUT/DELETE will override existing COOKIE/GET vars
$_REQUEST = $this->params + $_REQUEST;
} else if ($method == "GET") {
$this->params = $_GET;
} else if ($method == "POST") {
$this->params = $_POST;
}
}
}

Just remember, most webservers do not handle PUT & DELETE requests. Since you're making a library, I'd suggest thinking about accounting for this. Typically, there are two conventions you can use to mimic PUT & DELETE via POST.
请记住，大多数网络服务器不处理 PUT 和 DELETE 请求。既然你正在制作一个图书馆，我建议考虑考虑这一点。通常，您可以使用两种约定来通过 POST 模拟 PUT 和 DELETE。
- use a custom POST variable (ex. _METHOD=PUT) which overrides POST
- set a custom HTTP header (ex. X-HTTP-Method-Override: PUT)
- 使用覆盖 POST 的自定义 POST 变量（例如 _METHOD=PUT）
- 设置自定义 HTTP 标头（例如 X-HTTP-Method-Override: PUT）
Generally speaking, most RESTful services that don't allow PUT & DELETE directly will support at least one of those strategies. You can use cURL to set a custom header if you need via the CURLOPT_HTTPHEADERoption.
一般来说，大多数不允许直接执行 PUT 和 DELETE 的 RESTful 服务将至少支持其中一种策略。如果需要，您可以通过CURLOPT_HTTPHEADER选项使用 cURL 设置自定义标题。
// ex...
curl_setopt($ch, CURLOPT_HTTPHEADER, array('X-HTTP-Method-Override: PUT') );

I think you're mixing your verbs - PUT is for putting a file, POST is for posting variables (although you can POST a file).
我认为您在混合动词 - PUT 用于放置文件，POST 用于发布变量（尽管您可以发布文件）。
To set the post variables, use CURLOPT_POSTFIELDSwith either a string of param1=val1¶m2=val2or an associative array.
要设置 post 变量，请CURLOPT_POSTFIELDS与字符串param1=val1¶m2=val2或关联数组一起使用。
To do a DELETE, you'll want to use the curl option CURLOPT_CUSTOMREQUEST
要执行 DELETE，您需要使用 curl 选项 CURLOPT_CUSTOMREQUEST

This is my version of the DELETE for CI. It accepts GET-style arguments for the DELETE, even same name arguments, i.e.: GET /some/url?id=1&id=2&id=3
这是我的 CI DELETE 版本。它接受 DELETE 的 GET 样式参数，甚至是同名参数，即： GET /some/url?id=1&id=2&id=3
protected function _parse_delete()
{
$query = $_SERVER['QUERY_STRING'];
if ( !empty( $query ) )
{
foreach( explode('&', $query ) as $param )
{
list($k, $v) = explode('=', $param);
$k = urldecode($k);
$v = urldecode($v);
if ( isset( $this->_delete_args[$k] ) )
{
if ( is_scalar( $this->_delete_args[$k] ) )
{
$this->_delete_args[$k] = array( $this->_delete_args[$k] );
}
$this->_delete_args[$k][] = $v ;
}
else
{
$this->_delete_args[$k] = $v;
}
}
}
}

This is how i sole my DELETE problem:
这就是我唯一的 DELETE 问题：
==>> in REST_Controller.phpi replace the delault _parse_delete()function by :
==>> 在REST_Controller.php 中，我将 delault _parse_delete()函数替换为：
protected function _parse_delete()
{
$this->_delete_args = $_DELETE;
$this->request->format and $this->request->body = file_get_contents('php://input');
// Set up out DELETE variables (which shouldn't really exist, but sssh!)
parse_str(file_get_contents('php://input'), $this->_delete_args);
}
;) it works for me!
;） 这个对我有用！
