POST请求后如何获取页面正文

Question

I'm trying to make a PHP page that lets you upload a document to telegram servers and than retrives a file_id which is stored in the json of the redirect page. After some tutorials on YT this is the code:

<?php
    $botToken = "1099xxxxxx:AxxxE-g9qDI2Uxxxxxxxxxxxxxxxxxxxxxxxx";
    $website = "https://api.telegram.org/bot".$botToken;
?>

<form action="<?php echo $website.'/sendPhoto' ?>" method="post" enctype="multipart/form-data">
    <input type="text" name="chat_id" value="mychatid">
    <input type="file" name="photo">
    <input type="submit" value="send">
</form>

Redirect after submit

The goal is to retrive the file_id of the file and save it in a variable, possibly without opening another tab.

Thanks!

You've making the request to the Telegram API from the browser by submitting a form directly to it.

There is no way your PHP can get any information from that API that way.

As a side effect, you are giving your token (which should be kept secret) to every visitor who uses the form.

You need the browser to submit the form to a PHP program you control and then make the request to the Telegram API from your PHP and not from the browser.

The usual way to do this is with the cURL library .
