Question

我正在使用CakePHP 2创建Restful WebService但是，由于我无法捕获Post Data，因此我收到500内部服务器错误。 Rest服务器如下：

App::import ( 'Vendor', 'ExchangeFunctions', array ('file'=> 'exchange/exchangefunctions.php'));

class ExchangeController extends AppController
{
    public $components = array('RequestHandler');
    public
    function index()
    {
        $exchange = new ExchangeFunctions();
        $data = $this->request->data('json_decode');
        $exchange->username = $_POST['username'];
        $exchange->password = $_POST['password'];
        $emailList = $exchange->listEmails();
        $response  = new stdClass();
        $response->emailList = $emailList;
        foreach($emailList->messages as $listid => $email)
        {
            $tempEmail = $exchange->getEmailContent(
                $email->Id,
                $email->ChangeKey,
                TRUE,
                $_POST['attachmentPath']
            );
            $response->emails[$tempEmail['attachmentCode']] = $tempEmail;
        }
        $this->set('response', $response);
        $this->set('_serialize','response');
    }
}

客户端如下：

class ApitestController extends AppController
{
    Public function index()
    {
        $this->layout = 'ajax';
        $jRequestURLPrefix = 'http://localhost/EWSApi/';
        $postUrl           = $jRequestURLPrefix."exchange/index.json";

        $postData          = array(
            'username'      => 'username',
            'password'      => 'password',
            'attachmentPath'=> $_SERVER['DOCUMENT_ROOT'] . $this->base . DIRECTORY_SEPARATOR . 'emailDownloads' . DIRECTORY_SEPARATOR . 'attachments'
        );
        $postData = json_encode($postData);

        pr($postData);
        $ch       = curl_init( $postUrl );
        $options  = array(
            CURLOPT_RETURNTRANSFER=> true,
            CURLOPT_HTTPHEADER         => array(
                'Content-Type: application/json',
                'Content-Length: ' . strlen($postData)
            ),
            CURLOPT_CUSTOMREQUEST => 'GET',
            CURLOPT_POSTFIELDS     => $postData,
        );
        curl_setopt_array( $ch, $options );
        $jsonString = curl_exec($ch);
        curl_close($ch);
        $data       = json_decode($jsonString, FALSE);

        echo $jsonString;
    }

}

不确定我搞砸了！请帮忙！

Answer 1

好的，经过第二次看，还有一些可疑的东西。如前所述，您的CURL请求使用GET而不是POST。

$options  = array(
    ...
    CURLOPT_CUSTOMREQUEST => 'POST',
    CURLOPT_POSTFIELDS     => $postData,
);

另一件事是，您正在为POST CURL来JSON调用$_POST数据进行编码，但之后您尝试使用POST在另一方访问它但是，没有任何内容，$_POST数据必须是键/值查询字符串格式才能显示在php://input中。你必须阅读$data = $this->request->data('json_decode');，这可能是你试图用

做的

$data

但是，您必须使用CakeRequest::input()来实现此目的，当然您必须使用$_POST变量而不是$data = $this->request->input('json_decode'); $exchange->username = $data['username']; $exchange->password = $data['password']; .... $tempEmail = $exchange->getEmailContent( $email->Id, $email->ChangeKey, TRUE, $data['attachmentPath'] );

CURL

同时确保您的$options = array( ... CURLOPT_POSTFIELDS => $postData, CURLINFO_HEADER_OUT => true // supported as of PHP 5.1.3 ); curl_setopt_array($ch, $options); $result = curl_exec($ch); $info = curl_getinfo($ch); curl_close($ch); echo '<pre>'; print_r($info); echo '</pre>';请求看起来像预期的那样：
