php之使用 curl 在电报机器人中发送消息

我想从数据库中获取我的机器人消息并发送给用户，当我的文本只有 1 个单词时它可以工作，但现在它不起作用并显示 HTTP BAD REQUEST 400。我想我应该使用 curl，但我没有找不到任何可用于从电报机器人发送长消息的文档。(实际上是因为我是 php 的初学者)

这是我的代码

$botToken="something"; 
$website="https://api.telegram.org/bot".$botToken; 
 
 
$update = file_get_contents("php://input"); 
$update = json_decode($update, true); 
 
$chatID = $update["message"]["chat"]["id"]; 
$message = $update["message"]["text"]; 
 
define("dbhost", "localhost:3306"); define("dbuser", "sm"); 
define("dbpass", "sm"); define("database", "sm"); 
 
switch ($message){ 
 case "/get": 
  connected($chatID); 
 
break; 
 
 } 
 
function sendMessage($chatID,$message){ 
 
 
$url =$GLOBALS[website]."/sendMessage?chat_id=".$chatID."&text=".$message; 
 
//file_get_contents($url); 
    $ch = curl_init();  
 
    curl_setopt($ch, CURLOPT_URL, $url);  
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);  
 
    $output = curl_exec($ch); 
    curl_close($ch); 
 
   //checkJSON($chatID,$update); 
 
 } 
 
 function connected($chatID){ 
 
 $conn = mysql_connect(dbhost,dbuser,dbpass); 
 
 if(! $conn ) 
 { 
   die('Could not connect: ' . mysqli_error()); 
 } 
 
 
  mysql_select_db( database ); 
 
  $strSQL = "SELECT text FROM bott WHERE id= '1' "; 
  $result = mysql_query($strSQL) or die('SQL Error :: '.mysql_error()); 
   $row = mysql_fetch_assoc($result); 
  $message=$row['text']; 
  sendMessage($chatID,$message); 
  mysql_close($conn); 
  } 
 
 
 
 
function checkJSON($chatID,$update){ 
 
    $myFile = "log.txt"; 
    $updateArray = print_r($update,TRUE); 
    $fh = fopen($myFile, 'w') or die("can't open file"); 
    fwrite($fh, $chatID ."\n\n"); 
    fwrite($fh, $updateArray."\n\n"); 
    fclose($fh); 
  } 
 
 
 
 
?>

请您参考如下方法:

在 curl 方法中，您不应该使用 url 中的任何数据。
当您看到出现错误的网址时，其中的空格无效。
这是一个有效的 curl 代码:

$website="https://api.telegram.org/bot".$botToken; 
$chatId=1234567;  //Receiver Chat Id  
$params=[ 
    'chat_id'=>$chatID, 
    'text'=>'MoonLight', 
]; 
$ch = curl_init($website . '/sendMessage'); 
curl_setopt($ch, CURLOPT_HEADER, false); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt($ch, CURLOPT_POST, 1); 
curl_setopt($ch, CURLOPT_POSTFIELDS, ($params)); 
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); 
$result = curl_exec($ch); 
curl_close($ch);
