使用 curl 在电报机器人中发送消息

Question

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，但我没有发现任何文档对从电报机器人发送长消息有用。（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);
  }




?>

这是我使用 file_get_contents 时的错误

[08-Jul-2016 12:27:35 America/Chicago] PHP Warning:     file_get_contents(https://api.telegram.org/bot218048829:AAF7baKISagQfALp4OIPh-   yU_hMOnpFGU0A/sendMessage?   chat_id=98506693&text=Introduction%0D%0AA+COMPUTER+PROCESSOR+such+as+Intel%92s+i486+used+to+cost+around+the+same+as+a+small+car.+Nowadays+a+chip+with+similar+power+is+the+price+of+a+chocolate+bar.%0D%0A): failed to open stream: HTTP request failed!

此代码不会向用户发送任何内容。

在 curl 方法中，您不应该在 url 中使用任何数据。 如您所见，出现错误的 url 包含无效的空格。 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);
