[英]Telegram BOT Api: how to send a photo using PHP?
sendPhoto命令需要定義為InputFile or String
的參數photo
。
API 文檔說明:
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.
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.
所以我嘗試了這個方法
$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);
卷發已執行,但 Telegram 回復我:
Error: Bad Request: Wrong persistent file_id specified: contains wrong
characters or have wrong length
我也嘗試用file_get_contents
替換@/path...
,但在這種情況下,Telegram 給了我一個空的回復(並且curl_error
是空的!)。
使用 php + curl 將照片發送到電報的方式是什么?
這是我的工作解決方案,但需要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);
這段代碼可以幫助我從php.net網站獲得大量幫助
訪問http://php.net/manual/en/class.curlfile.php#115161 (在php網站上投票該代碼) 。
我只是在此代碼中更改報頭以使電報機器人發送圖像,只需復制此功能
function curl_custom_postfields($ch, array $assoc = array(), array $files = array()) {
// invalid characters for "name" and "filename"
static $disallow = array("\0", "\"", "\r", "\n");
// build normal parameters
foreach ($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
),
));
}
基本嘗試:現在只需通過發送帶有路徑和聊天ID的照片名稱來使用此代碼,方法如下:-
$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);
要發送png或其他方法,請根據需要更改curl_custom函數。
我在網上搜索了很多內容,但沒有找到答案。 但是,您的問題解決了我的問題……我只是更改了您的代碼,然后為我解答了……我將您的代碼更改為:
$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;
您可以使用以下API: https : //github.com/mgp25/Telegram-Bot-API
例:
$tg->sendPhoto($chat_id, $image, $caption);
您可以使用存儲的圖像或URL。
這是個壞主意,但是您可以使用類似的方法:
#!/bin/bash
set -x
set -e
BDIR=/tmp/${RANDOM}
TG_TOKEN=""
TG_CHAT_ID=
mkdir -p ${BDIR}
chmod -R 777 ${BDIR}
su postgres -c "pg_dumpall -f ${BDIR}/postgre.sql"
tar czf ${BDIR}/${HOSTNAME}.tar.gz /var/lib/grafana/ /etc/grafana/ ${BDIR}/postgre.sql
curl -F caption="$(date)" -F chat_id="${TG_CHAT_ID}" -F document=@"${BDIR}/${HOSTNAME}.tar.gz" https://api.telegram.org/bot${TG_TOKEN}/sendDocument
rm -rf ${DBIR}
<?php
$BASH_Command='curl -s -X POST "https://api.telegram.org/bot<YourToken>/sendPhoto?chat_id=<YourID>" -F photo="@/path/to/imagefile.jpeg" -F caption="TheImage" > /dev/null &';
echo exec($BASH_Command);
?>
我想我應該擴展答案以包括從外部 url 上傳,但它仍然涉及首先將圖像保存到文件夾的過程。 然后我為圖像添加了標題。
$bot_url = "https://api.telegram.org/bot<bot_id>/";
$url = $bot_url . "sendPhoto?chat_id=" . $chat_id ;
$caption = 'Telegram Image SendPhoto function';
$img = '/path/to/save_image.png'; //local path where image should be saved
/* Get the image from the URL and save to your own path. You need to add
allow_url_fopen=On to your php.ini file for the below code to work */
file_put_contents($img, file_get_contents("https://your_image.com/pic.jpg"));
$post_fields = array('chat_id' => $chat_id,
'photo' => new CURLFile(realpath($img)),
'caption' => $caption
);
$ch = curl_init();
curl_setopt($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);
curl_close($ch); //close curl
就這樣!
