我正在研究一个将调用对话框的斜杠命令。
$dialog = [
'callback_id' => 'ryde-46e2b0',
'title' => 'Request a Ride',
'submit_label' => 'Request',
'elements' => [
[
'type' => 'text',
'label' => 'Pickup Location',
'name' => 'loc_origin'
],
[
'type' => 'text',
'label' => 'Dropoff Location',
'name' => 'loc_destination'
]
]
];
// get trigger ID from incoming slash request
$trigger = filter_input(INPUT_POST, "trigger_id");
// define POST query parameters
$query = [
'token' => 'XXXXXXXXX MY TOKEN XXXXXXXXX',
'dialog' => json_encode($dialog),
'trigger_id' => $trigger
];
// define the curl request
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://slack.com/api/dialog.open');
curl_setopt($ch, CURLOPT_HTTPHEADER, [
'Content-Type: application/x-www-form-urlencoded'
]);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
// set the POST query parameters
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($query));
// execute curl request
$response = curl_exec($ch);
// close
curl_close($ch);
var_export($response);
当我发出斜杠命令时,我的测试对话框成功打开
然后我在字段中填写两个测试值test1
并test2
提交请求。我的端点被对话数据有效负载正确命中,但发送的数据不是有效的 JSON:
的值$_POST
是:(我已经用 xxx 掩盖了所有识别令牌/ID)
{"payload":"{\\\"type\\\":\\\"dialog_submission\\\",\\\"token\\\":\\\"XXX\\\",\\\"action_ts\\\":\\\"1536603864.688426\\\",\\\"team\\\":{\\\"id\\\":\\\"xxx\\\",\\\"domain\\\":\\\"ourdomain\\\"},\\\"user\\\":{\\\"id\\\":\\\"xxx\\\",\\\"name\\\":\\\"my_name\\\"},\\\"channel\\\":{\\\"id\\\":\\\"xxx\\\",\\\"name\\\":\\\"directmessage\\\"},\\\"submission\\\":{\\\"loc_origin\\\":\\\"test1\\\",\\\"loc_destination\\\":\\\"test2\\\"},\\\"callback_id\\\":\\\"ryde-46e2b0\\\",\\\"response_url\\\":\\\"https:\\\\/\\\\/hooks.slack.com\\\\/app\\\\/XXX\\\\/XXX\\\\/XXX\\\",\\\"state\\\":\\\"\\\"}"}
这是一个无效的 JSON,即使删除了“\\”实例也是如此。为什么会这样?
以下是处理来自 Slack 的 POST 的代码:
error_log(" -- dialog response: " . json_encode($_POST) . "\n", 3, './runtime.log');
这导致了上面的输出。
