如何将大文件从URL发送到Telegram机器人? [英] How to send big files from URL to Telegram bot?

问题描述

我有一些大文件(MP4和Zip格式)，我想通过Telegram bot将它们发送到我的聊天室，我使用下面的代码:

I have some big size files (in MP4 and Zip formats) and I want to send them to my chat by Telegram bot, I used the code below:

file_get_contents('https://api.telegram.org/bot[[app:token]]/sendDocument?chat_id=24523586&document='.$fileAddress);

但是它只能发送小于50MB的小文件！但是我知道通过file_id发送的文档没有文件大小限制.您可以看到此页面
现在如何为文件创建file_id?我的文件已上传到服务器上，并且正在使用PHP.

But it just can send files with small sizes, less than 50MB! But I know there is no file size limitation for documents which are sending by file_id. You can see this page
Now how can I make file_id for my files? My files are uploaded on my server and I am using PHP.

推荐答案

Telegram机器人API只能通过url参数发送小于20 MB的文件，您应该查找

Telegram bot API can only send files less than 20 MB by url param, you should lookup Sending Files section.

如果要发送20-50 MB的文件，则应下载并重新上传到Telegram bot API服务器.
您可以参考这个简单的代码

If you want to send 20-50 MB files, you should download and re-upload to Telegram bot API server.
You can refer this simple code

$curl = curl_init();
curl_setopt_array($curl, [
    CURLOPT_URL => 'https://api.telegram.org/bot131210513:AXXXXXX/sendDocument?caption=Hello+World&chat_id=24523586',
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_HTTPHEADER => [
        'Content-Type: multipart/form-data'
    ],
    CURLOPT_POST => true,
    CURLOPT_POSTFIELDS => [
        'document' => curl_file_create('/etc/hosts', 'plain/text', 'Hosts-file.txt')
    ]
]);
$data = curl_exec($curl);
curl_close($curl);
