如何使用Telegram API接收圖像？

Question

是否可以接收任何用戶發送給機器人的圖像（並將其存儲在服務器上）？

如果發送圖像，我收到此JSON帖子。這是一個指向Telegram Bot-API描述的鏈接。我不知道是否有可能接收整個圖像或不：與getFilehttps://core.telegram.org/bots/api#available-types

{"update_id":XXXXX, 
"message":{"message_id":2222,"from":{"id":XXXXX,"first_name":"Christoph","last_name":"XXXXX"},"chat":{"id":XXXXX,"first_name":"Christoph","last_name":"XXXXX"},"date":1435704055,"forward_from":{"id":XXXXX,"first_name":"Christoph","last_name":"XXXXX"},"forward_date":1435703471,"photo":[{"file_id":"AgADAgADmaoxG9KknwF4O978o3EMqb_EWSoABI5s-WWq46dqiR0AAgI","file_size":998,"width":51,"height":90},{"file_id":"AgADAgADmaoxG9KknwF4O978o3EMqb_EWSoABHax4HvxYqktiB0AAgI","file_size":9912,"width":180,"height":320},{"file_id":"AgADAgADmaoxG9KknwF4O978o3EMqb_EWSoABNzzDwp3sT2whx0AAgI","file_size":41020,"width":450,"height":800},{"file_id":"AgADAgADmaoxG9KknwF4O978o3EMqb_EWSoABE0Gg-AefJ7Yhh0AAgI","file_size":66058,"width":720,"height":1280}]}}

電報支持下載文件現在：

你可以看到它的API文檔中：https://core.telegram.org/bots/api#getfile

Answer 2

可以從電報服務器下載圖像。 這樣做：
1.使用getFile API獲取文件

//Telegram link 
    $telegram_link = 'https://api.telegram.org/bot' . $this->tg_configs['api_key'] . '/getFile?file_id=' . $photo['file_id']; 

獲取文件路徑

//創建狂飲客戶 $ guzzle_client =新GuzzleClient（）;

//Call telegram 
$request = $guzzle_client->get($telegram_link); 
//Decode json 
$json_response = json_decode($request->getBody(), true); 
if ($json_response['ok'] == 'true') { 

     //Telegram file link 
    $telegram_file_link = 'https://api.telegram.org/file/bot' . $this->tg_configs['api_key'] . '/' . $json_response['result']['file_path']; 

如果使用PHP使用Intervention/Image下載的圖片，並將其保存在服務器上。

//建立上傳路徑 $ upload_path = public_path（）。 \配置::獲得（ '媒體:: media.uploadPath'）; //獲取圖片 $ image = $ thumbnail = InterventionImage :: make（$ telegram_file_link）;

//Get mime 
    $mime = $image->mime(); 

    if ($mime == 'image/jpeg') { 
     $extension = '.jpg'; 
    } elseif ($mime == 'image/png') { 
     $extension = '.png'; 
    } elseif ($mime == 'image/gif') { 
     $extension = '.gif'; 
    } else { 
     $extension = ''; 
    }//E# if else statement 
    //Resize images 
    $image->resize(\Config::get('media::media.mainWidth'), \Config::get('media::media.mainHeight')); 
    $thumbnail->resize(\Config::get('media::media.thumbnailWidth'), \Config::get('media::media.thumbnailHeight')); 

    //Build media name 
    $media_name = \Str::random(\Config::get('media::media.mediaNameLength')) . $extension; 

    //Save images 
    $image->save($upload_path . '/' . $media_name); 
    $thumbnail->save($upload_path . '/thumbnails/' . $media_name);
