Discord Post Message To Channel Using cURL - PHP - php

Question

I am currently trying to post a message on my Discord channel trying to use a cURL POST type. The issue that I am getting when I run my code is that it is giving me a 401 error saying I'm unauthorized. I am running my PHP code on a webserver using xampp localhost. I also went in and tried to authorize my application bot via URL link (https://discordapp.com/oauth2/authorize?client_id=MYAPPLICATIONID&scope=bot&permissions=8) and have successfully added the bot into my channel. Have a look at my code
$data = array("Authorization: Bot" => $clientSecret, 'content' => 'Test Message');
$data_string = json_encode($data);
$ch = curl_init('https://discordapp.com/api/v6/channels/'.$myChannel.'/messages');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Content-Length: ' . strlen($data_string))
);
$answer = curl_exec($ch);
echo $answer;
if (curl_error($ch)) {
echo curl_error($ch);
}
I get $clientSecret from the application page to reveal my client secret token and $myChannel is my discords channel/server id.
NOTE: I have modeled my code off another stackoverflow answer given here discord php curl login Fail . So I am unsure if I am using the correct syntax for the an application bot

Answer 1

Here is full code (Without cURL). Just replace the string WEBHOOK_HERE with your bot's webhook:
<?php
$message = $_POST['message'];
$data = ['content' => $message];
$options = [
'http' => [
'method' => 'POST',
'header' => 'Content-Type: application/json',
'content' => json_encode($data)
]
];
$context = stream_context_create($options);
$result = file_get_contents('WEBHOOK_HERE', false, $context);
?>
<form method="post">
Type your message here :<br><input type="text" name="message"><br>
<input type="submit" value="Submit">
</form>
I'm new here so I hope you enjoy the code!

Close! Your solution has an error.
<?php
$myChannel = "CHANNEL_ID";
$myToken = "TOKEN";
$msg = 'Test Message';
$data = array('content' => $msg);
$data_string = json_encode($data);
$ch = curl_init('https://discordapp.com/api/v6/channels/' . $myChannel . '/messages');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Content-Length: ' . strlen($data_string),
'Authorization: Bot ' . $myToken
)
);
$answer = curl_exec($ch);
echo $answer;
if (curl_error($ch)) {
echo curl_error($ch);
}
?>
I just tested this on my server and it worked. with Bot ' . $token it failed.

I actually had a tough time searching the web for this, without using webhooks. I wanted to post the message as a bot, not a webhook. The error was with your authorization, as it needs to be in the header... So I'm posting the correct solution here for future googlers.
<?php
$myChannel = "CHANNEL_ID";
$myToken = "TOKEN";
$msg = 'Test Message';
$data = array('content' => $msg);
$data_string = json_encode($data);
$ch = curl_init('https://discord.com/api/v6/channels/' . $myChannel . '/messages');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Content-Length: ' . strlen($data_string),
'Authorization: Bot ' . $myToken
)
);
$answer = curl_exec($ch);
echo $answer;
if (curl_error($ch)) {
echo curl_error($ch);
}
?>
