我通过OAuth2 URL(https://discordapp.com/api/oauth2/authorize?client_id=398437519408103444&permissions=59392&scope=bot)验证我的机器人

我想在我的discord服务器上发送消息到频道

码：

$curl = curl_init();

curl_setopt($curl, CURLOPT_URL, 'https://discordapp.com/api/channels/'.$channel_id.'/messages');

curl_setopt($curl, CURLOPT_HTTPHEADER, [

// 'Content-Type: application/json',

'Authorization: Bot '.$this->token

]);

curl_setopt($curl, CURLOPT_POST, true);

curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode([

'content' => 'test'

]));

curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);

$server_output = curl_exec($curl);

curl_close ($curl);

var_dump(json_decode($server_output, true));

但回应是：

array(2) {

["code"]=>

int(40001)

["message"]=>

string(12) "Unauthorized"

}
