删除请求

我正在尝试使用 PHP 和 cURL 执行 DELETE http 请求。

我在很多地方读过如何做这件事，但似乎没有一样对我有用。

我是这么做的:

public function curl_req($path,$json,$req)
{
$ch = curl_init($this->__url.$path);
$data = json_encode($json);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $req);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json','Content-Length: ' . strlen($data)));
$result = curl_exec($ch);
$result = json_decode($result);
return $result;
}

然后我继续使用我的函数:

public function deleteUser($extid)
{
$path = "/rest/user/".$extid."/;token=".$this->__token;
$result = $this->curl_req($path,"","DELETE");
return $result;


}

这给了我 HTTP 内部服务器 ERROR。 在使用与 GET 和 POST 相同的 curl _ req 方法的其他函数中，一切都很顺利。

那我做错了什么？

最佳答案

我终于自己解决了这个问题。如果其他人也有这个问题，我的解决办法是:

我创造了一种新方法:

public function curl_del($path)
{
$url = $this->__url.$path;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "DELETE");
$result = curl_exec($ch);
$httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);


return $result;
}

由于这似乎对一些人有所帮助，下面是我最后的 curl DELETE 方法，它以 JSON 解码的对象返回 HTTP 响应:

  /**
* @desc    Do a DELETE request with cURL
*
* @param   string $path   path that goes after the URL fx. "/user/login"
* @param   array  $json   If you need to send some json with your request.
*                         For me delete requests are always blank
* @return  Obj    $result HTTP response from REST interface in JSON decoded.
*/
public function curl_del($path, $json = '')
{
$url = $this->__url.$path;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "DELETE");
curl_setopt($ch, CURLOPT_POSTFIELDS, $json);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
$result = json_decode($result);
curl_close($ch);


return $result;
}

To call GET,POST,DELETE,PUT All kind of request, i have created one common function

function CallAPI($method, $api, $data) {
$url = "http://localhost:82/slimdemo/RESTAPI/" . $api;
$curl = curl_init($url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    

switch ($method) {
case "GET":
curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($data));
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "GET");
break;
case "POST":
curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($data));
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "POST");
break;
case "PUT":
curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($data));
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "PUT");
break;
case "DELETE":
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "DELETE");
curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($data));
break;
}
$response = curl_exec($curl);
$data = json_decode($response);


/* Check for 404 (file not found). */
$httpCode = curl_getinfo($curl, CURLINFO_HTTP_CODE);
// Check the HTTP Status code
switch ($httpCode) {
case 200:
$error_status = "200: Success";
return ($data);
break;
case 404:
$error_status = "404: API Not found";
break;
case 500:
$error_status = "500: servers replied with an error.";
break;
case 502:
$error_status = "502: servers may be down or being upgraded. Hopefully they'll be OK soon!";
break;
case 503:
$error_status = "503: service unavailable. Hopefully they'll be OK soon!";
break;
default:
$error_status = "Undocumented error: " . $httpCode . " : " . curl_error($curl);
break;
}
curl_close($curl);
echo $error_status;
die;
}

CALL 删除方法

$data = array('id'=>$_GET['did']);
$result = CallAPI('DELETE', "DeleteCategory", $data);

CALL Post Method

$data = array('title'=>$_POST['txtcategory'],'description'=>$_POST['txtdesc']);
$result = CallAPI('POST', "InsertCategory", $data);

调用获取方法

$data = array('id'=>$_GET['eid']);
$result = CallAPI('GET', "GetCategoryById", $data);

CALL Put 方法

$data = array('id'=>$_REQUEST['eid'],'title'=>$_REQUEST['txtcategory'],'description'=>$_REQUEST['txtdesc']);
$result = CallAPI('POST', "UpdateCategory", $data);
