Telegram BOT Api: how to send a photo using PHP?
提问by realtebo
The sendPhotocommand require an argument photodefined as InputFile or String.
所述sendPhoto命令需要一个参数photo定义为InputFile or String。
The API doc tells:
API 文档说明：
Photo to send. You can either pass a file_id as String to resend a photo
that is already on the Telegram servers, or upload a new photo using
multipart/form-data.
And
和
InputFile
This object represents the contents of a file to be uploaded. Must be
posted using multipart/form-data in the usual way that files are
uploaded via the browser.
So I tried this method
所以我尝试了这个方法
$bot_url = "https://api.telegram.org/bot<bot_id>/";
$url = $bot_url . "sendPhoto?chat_id=" . $chat_id;
$ch = curl_init();
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
"Content-Type:multipart/form-data"
));
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, array(
"photo" => "@/path/to/image.png",
));
curl_setopt($ch, CURLOPT_INFILESIZE, filesize("/root/dev/fe_new.png"));
$output = curl_exec($ch);
The curls is executed, but Telegram reply this to me:
卷发已执行，但 Telegram 回复我：
Error: Bad Request: Wrong persistent file_id specified: contains wrong
characters or have wrong length
I also tried replacing @/path...with a file_get_contents, but in this case Telegram give me an empty reply (and curl_erroris empty !).
我也尝试用@/path...a替换file_get_contents，但在这种情况下 Telegram 给了我一个空的回复（并且curl_error是空的！）。

This is my working solution, but it requires PHP 5.5:
这是我的工作解决方案，但它需要 PHP 5.5：
$bot_url = "https://api.telegram.org/bot<bot_id>/";
$url = $bot_url . "sendPhoto?chat_id=" . $chat_id ;
$post_fields = array('chat_id' => $chat_id,
'photo' => new CURLFile(realpath("/path/to/image.png"))
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
"Content-Type:multipart/form-data"
));
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_fields);
$output = curl_exec($ch);

This code helps me alot which I get from php.net website here
这段代码对我有很大帮助，我从 php.net 网站获得了这里
Visit http://php.net/manual/en/class.curlfile.php#115161(Vote Up this code in php website).
访问http://php.net/manual/en/class.curlfile.php#115161 （在 php 网站上投票此代码）。
I just change headers in this code for telegram bot to send image just copy this function
我只是更改此代码中的标题，以便电报机器人发送图像只需复制此功能
function curl_custom_postfields($ch, array $assoc = array(), array $files = array()) {
// invalid characters for "name" and "filename"
static $disallow = array("$array1=array('chat_id'=><here_chat_id>);
$array2=array('photo'=>'index.jpg') //path
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,"https://api.telegram.org/<bot_token>/sendPhoto");
curl_custom_postfields($ch,$array1,$array2);//above custom function
$output=curl_exec($ch);
close($ch);
", "\"", "\r", "\n");
// build normal parameters
foreach ($assoc as $k => $v) {
$k = str_replace($disallow, "_", $k);
$body[] = implode("\r\n", array(
"Content-Disposition: form-data; name=\"{$k}\"",
"",
filter_var($v),
));
}
// build file parameters
foreach ($files as $k => $v) {
switch (true) {
case false === $v = realpath(filter_var($v)):
case !is_file($v):
case !is_readable($v):
continue; // or return false, throw new InvalidArgumentException
}
$data = file_get_contents($v);
$v = call_user_func("end", explode(DIRECTORY_SEPARATOR, $v));
$k = str_replace($disallow, "_", $k);
$v = str_replace($disallow, "_", $v);
$body[] = implode("\r\n", array(
"Content-Disposition: form-data; name=\"{$k}\"; filename=\"{$v}\"",
"Content-Type: image/jpeg",
"",
$data,
));
}
// generate safe boundary
do {
$boundary = "---------------------" . md5(mt_rand() . microtime());
} while (preg_grep("/{$boundary}/", $body));
// add boundary for each parameters
array_walk($body, function (&$part) use ($boundary) {
$part = "--{$boundary}\r\n{$part}";
});
// add final boundary
$body[] = "--{$boundary}--";
$body[] = "";
// set options
return @curl_setopt_array($ch, array(
CURLOPT_POST => true,
CURLOPT_POSTFIELDS => implode("\r\n", $body),
CURLOPT_HTTPHEADER => array(
"Expect: 100-continue",
"Content-Type: multipart/form-data; boundary={$boundary}", // change Content-Type
),
));
}
Basic Try:Now just use this code by sending photo name with path and chat id here is it how:-
基本尝试：现在只需通过发送带有路径和聊天 ID 的照片名称来使用此代码，方法如下：-
$chat_id=chat Id Here;
$bot_url = "https://api.telegram.org/botYOUR_BOT_TOKEN/";
$url = $bot_url . "sendPhoto?chat_id=" . $chat_id;
$ch = curl_init();
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
"Content-Type:multipart/form-data"
));
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, array(
"photo" => "@path/to/image.png",
));
curl_setopt($ch, CURLOPT_INFILESIZE, filesize("path/to/image.png"));
$output = curl_exec($ch);
print$output;
For sending png or other methods change curl_custom function according to your need.
对于发送 png 或其他方法，请根据需要更改 curl_custom 函数。

You can use either a stored image or URL.
