如何在 PHP 中从 Telegram 获取 callback_data

Question

我想从响应中获取回调数据，但数组为空。

我正在尝试在消息 callback_data 数组中显示。

这是我的代码：

$botToken = "token";
$botAPI = "https://api.telegram.org/bot" . $botToken;
$update = json_decode(file_get_contents('php://input'), TRUE);
$message = $update["message"]["text"]
$chatId = $update["message"]["chat"]["id"];
$callback_query = $update['callback_query'];
$callback_query_data = $callback_query['data'];
$url = $botAPI . '/sendMessage?chat_id=' . $chatId . '&text=';

if(isset($callback_query)){
    file_get_contents($url . $callback_query_data);
}

if($message == "/start"){
    $parameters = array('chat_id' => $chatId, "text" => "Здравствуйте. Выберите язык. \nАссалом. Забонро интихоб кунед.\nHi! Select your language.");
    $parameters["method"] = "sendMessage";
    $keyboard = ['inline_keyboard' => [[
        ['text' => "Точики", 'callback_data' => 'tajik'],
        ['text' =>  "Русский", 'callback_data' => 'russian'],
        ['text' => 'English', 'callback_data' => 'english']
    ]]];
    $parameters["reply_markup"] = json_encode($keyboard, true);
    echo json_encode($parameters);
}

代码中有一些小错误，我会尽力解决；

只有 webhooks 才能使用 php://input，你告诉 Telegram 你脚本的位置了吗？

https://api.telegram.org/bot<MY-TOKEN>/setWebhook?url=https://example.com/telegram/script.php

$callback_query_data = $callback_query['data']

仅在按下按钮时设置，应在检查是否有回调数据后调用

if (isset($update['callback_query'])) {
    $callback_query_data = $update['callback_query']['data'];
}

工作示例：

<?php

    $update = json_decode(file_get_contents('php://input'), TRUE);

    $botToken = "<MY-TOKEN>";
    $botAPI = "https://api.telegram.org/bot" . $botToken;

    // Check if callback is set
    if (isset($update['callback_query'])) {

        // Reply with callback_query data
        $data = http_build_query([
            'text' => 'Selected language: ' . $update['callback_query']['data'],
            'chat_id' => $update['callback_query']['from']['id']
        ]);
        file_get_contents($botAPI . "/sendMessage?{$data}");
    }

    // Check for normal command
    $msg = $update['message']['text'];
    if ($msg === "/start") {

        // Create keyboard
        $data = http_build_query([
            'text' => 'Please select language;',
            'chat_id' => $update['message']['from']['id']
        ]);
        $keyboard = json_encode([
            "inline_keyboard" => [
                [
                    [
                        "text" => "english",
                        "callback_data" => "english"
                    ],
                    [
                        "text" => "russian",
                        "callback_data" => "russian"
                    ]
                ]
            ]
        ]);

        // Send keyboard
        file_get_contents($botAPI . "/sendMessage?{$data}&reply_markup={$keyboard}");
    }

如有不明之处请告诉我！
