Question

sendPhoto命令需要将参数photo定义为InputFile or String。

API文档告诉：

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.

并且

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.

所以我试过这个方法

    $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);

卷发被执行，但Telegram回复给我：

Error: Bad Request: Wrong persistent file_id specified: contains wrong
characters or have wrong length

我也尝试用@/path...替换file_get_contents，但在这种情况下，Telegram会给我一个空的回复（curl_error为空！）。

使用php + curl将照片发送到电报的方式是什么？

Answer 1

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);

Answer 2

此代码可以帮助我从php.net网站获取很多内容

访问http://php.net/manual/en/class.curlfile.php#115161 （在php网站上投票这个代码）。

我只是更改此代码中的标题，用于发送图像的电报机器人只需复制此功能

function curl_custom_postfields($ch, array $assoc = array(), array $files = array()) {

          // invalid characters for "name" and "filename"
          static $disallow = array("\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
              ),
          ));
      }

基本尝试：现在只需使用路径和聊天ID发送照片名称即可使用此代码这是如何： -

$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);

要发送png或其他方法，请根据需要更改curl_custom功能。

Answer 3

我在网上搜索了很多但没找到答案。但是，你的问题解决了我的问题...我只是改变了你的代码，并为我解答了...... 我将您的代码更改为：

$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;

Answer 4

您可以使用此API：https://github.com/mgp25/Telegram-Bot-API

示例：

$tg->sendPhoto($chat_id, $image, $caption);

您可以使用存储的图片或网址。

Answer 5

<?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);
?>
