松弛PHP API-避免超时错误

Question

我试图使用Slack自定义命令，但不太确定如何使用延迟消息，因为Yoda Speak外部API需要超过3秒来响应。

我做了以下工作：

• 在我的例子中发送了slack命令/yoda，并收到了reponse_url.
• 使用以下内容将以下内容发送到响应URL。

$data_string = '{"response_type": "in_channel", "text":"Checking,please wait..."}' ;
$chs = curl_init();
curl_setopt($chs, CURLOPT_URL, $response_url);
curl_setopt($chs, CURLOPT_POST, true);
curl_setopt($chs, CURLOPT_POSTFIELDS, $data_string); 
curl_setopt($chs, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($chs, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($chs, CURLOPT_RETURNTRANSFER, true);
curl_setopt($chs, CURLOPT_POST, 1);
curl_setopt($chs, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));
$results = curl_exec($chs);

null

$chsres = curl_init();
curl_setopt($chsres, CURLOPT_URL, "https://yoda.p.mashape.com/yoda?sentence=welcome+to+stack");
curl_setopt($chsres, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($chsres, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($chsres, CURLOPT_VERBOSE, true);
curl_setopt($chsres, CURLOPT_TIMEOUT, 45);
curl_setopt($chsres, CURLOPT_RETURNTRANSFER, true);
curl_setopt($chsres, CURLOPT_HTTPHEADER, array('Content-Type:application/json', "X-Mashape-Key:> deMeGoBfMvmshQSemozTqJEY9z0jp1eIhuAjsnx9cQAQsHUifD"));
$resultchsres = curl_exec($chsres);
echo $resultchsres;

$response_url = $_POST['response_url'];
$text = $_POST['text'];

$term = str_replace(' ', '+', $text);

//https://paypal.slack.com/services/B0VQMHX8W#service_setup
//initial respond with 200OK for timeout
ignore_user_abort(true);
set_time_limit(0);
ob_start();
echo('{"response_type": "in_channel", "text": "Checking, please wait..."}');
header($_SERVER["SERVER_PROTOCOL"] . " 200 OK");
header("Content-Type: application/json");
header('Content-Length: '.ob_get_length());
ob_end_flush();
ob_flush();
flush();


    $chsres = curl_init();
    curl_setopt_array($chsres, array(
        CURLOPT_URL => "https://yoda.p.mashape.com/yoda?sentence=$term",
        CURLOPT_SSL_VERIFYPEER => FALSE,
        CURLOPT_SSL_VERIFYHOST => FALSE,
        CURLOPT_VERBOSE => true,
        CURLOPT_RETURNTRANSFER => FALSE,
        CURLOPT_HTTPHEADER => array('Content-Type:application/json', "X-Mashape-Key: deMeGoBfMvmshQSemozTqJEY9z0jp1eIhuAjsnx9cQAQsHUifD"),
        CURLOPT_RETURNTRANSFER => true
    ));
    $yodaresponse = curl_exec($chsres);

    $curl = curl_init();
    curl_setopt_array($curl, array(
        CURLOPT_URL => $response_url,
        CURLOPT_POST => 1,
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_POSTFIELDS => $yodaresponse
    ));

    $resp = curl_exec($curl);
    var_dump($resp);
    curl_close($curl);

我仍然得到相同的错误“该死-那个斜杠命令不起作用（错误消息:超时达到)。在slash-command管理命令”

你做的都是对的，只是需要改变顺序。

立即以200 OK响应来响应原始请求。详细信息请参见此答案，但本质上：

ignore_user_abort(true);
ob_start();
echo('{"response_type": "in_channel", "text": "Checking, please wait..."}');
header($_SERVER["SERVER_PROTOCOL"] . " 200 OK");
header("Content-Type: application/json");
header('Content-Length: '.ob_get_length());
ob_end_flush();
ob_flush();
flush();

然后使用curl发出Yoda API请求，就像您正在做的那样
