我正在尝试使用PHP和curl进行删除http请求。

我在许多地方读过如何做,但似乎没有什么对我有用。

我就是这样做的:

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内部服务器错误。在我的其他函数中使用相同的卷曲[医]使用GET和POST的req方法,一切都进行得很顺利。

那我做错什么了?

我创建了一个新方法:

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;
}

下面是我的最后一个curl删除方法,它返回JSON解码对象中的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;
}

为了调用GET、POST、DELETE、PUT各种请求,我创建了一个通用函数

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;
}

调用删除方法

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

呼叫后法

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

呼叫获取方法

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

呼叫放法

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