PHP 发送带有附件和变量值的松弛消息

Question

正在尝试 send messages to slack 已安装 incoming webhooks 的频道。 Attachments 需要与消息一起发送，PHP 变量保存这些 URL。类似地，我想发送一些 ID's，它们再次保存在一些 PHP 变量中。这是我的 server side PHP 代码：

<?php

$testplan_name = $_POST[plan]; //test plan name coming from the client
$url1 = $_POST[run_url]; //run url coming from the client
$url2 = $_POST[plan_url]; //plan url coming from the client
$room = "random"; 
$icon_url = ":ghost:";
$username = "Test";
$attachments = array([
            'fallback' => 'Hey! See this message',
            'pretext'  => 'Here is the plan name ${testplan_name}',
            'color'    => '#ff6600',
            'fields'   => array(
                [
                    'title' => 'Run URL',
                    'value' => 'url1',
                    'short' => true
                ],
                [
                    'title' => 'Build URL',
                    'value' => 'url2',
                    'short' => true
                ]
            )
        ]);

$data = "payload=" . json_encode(array(         
        "channel"       =>  "#{$room}",
        "icon_emoji"    =>  $icon_url,
        "username"      =>  $username,
        "attachments"   =>  $attachments

    ));

$url = "https://hooks.slack.com/services/XXXX/XXX/XXXXXXXXXXXXX"; //got from slack as a webhook URL

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$result = curl_exec($ch);
echo var_dump($result);
if($result === false)
{
    echo 'Curl error: ' . curl_error($ch);
}

curl_close($ch);

如果你在上面的 attachments 变量中看到，pretext 中有一个变量试图打印顶部声明的 ${testplan_name} 的值。但是，它似乎不起作用，程序无法将 post 消息发送到松弛通道。同样，我想在 attachments -> fields 值中打印 url1 和 url2 的值，如上所示（我尝试打印的方式）。如果我在 posting 消息时不尝试使用任何变量并获取它们的值，该程序就可以正常工作。如何在消息中打印这些变量的值？

试试这个>

    $attachments = array([
        'fallback' => 'Hey! See this message',
        'pretext'  => 'Here is the plan name '.$testplan_name,
        'color'    => '#ff6600',
        'fields'   => array(
            [
                'title' => 'Run URL',
                'value' => $url1,
                'short' => true
            ],
            [
                'title' => 'Build URL',
                'value' => $url2,
                'short' => true
            ]
        )
    ]);
