我正在尝试使用 PHP 和 cURL 执行 DELETE http 请求。

我已经在很多地方阅读了如何做到这一点，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;
}

然后我继续使用我的功能：

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，使用与 GET 和 POST 相同的 curl_req 方法，一切顺利。

那么我做错了什么？

我终于自己解决了这个问题。如果其他人遇到此问题，这是我的解决方案：

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;
}

由于这似乎对某些人有所帮助，因此这是我的最终 curl DELETE 方法，它以 JSON 解码对象返回 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;
}

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;
}

CALL 删除方法

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

CALL 发布方法

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

CALL 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);

我自己的带有 wsse 身份验证的课程请求

class Request {

    protected $_url;

    public function __construct($url, $username, $apiUserKey) {

    public function getHeader() {

        $created = date('c');
        $digest = base64_encode(sha1(base64_decode($nonce) . $created . $this->_apiKey, true));

        $wsseHeader = "Authorization: WSSE profile=\"UsernameToken\"\n";
        $wsseHeader .= sprintf(
            'X-WSSE: UsernameToken Username="%s", PasswordDigest="%s", Nonce="%s", Created="%s"', $this->_username, $digest, $nonce, $created
        );

        return $wsseHeader;
    }

    public function curl_req($path, $verb=NULL, $data=array()) {                    

        $wsseHeader[] = "Accept: application/vnd.api+json";
        $wsseHeader[] = $this->getHeader();

        $options = array(
            CURLOPT_URL => $this->_url . $path,
            CURLOPT_HTTPHEADER => $wsseHeader,
            CURLOPT_RETURNTRANSFER => true, 
            CURLOPT_HEADER => false             
        );                  

        if( !empty($data) ) {
            $options += array(
                CURLOPT_POSTFIELDS => $data,
                CURLOPT_SAFE_UPLOAD => true
            );                          
        }

        if( isset($verb) ) {
            $options += array(CURLOPT_CUSTOMREQUEST => $verb);                          
        }

        $ch = curl_init();
        curl_setopt_array($ch, $options);
        $result = curl_exec($ch);                   

        if(false === $result ) {
            echo curl_error($ch);
        }
        curl_close($ch);

        return $result; 
    }
}
