如何通过php或wget从Slack下载图像

我试图通过以下代码从Slack通道下载图像,但我只是得到页面的html代码.

我是在做傻事,还是有诀窍让这很难？

<?php

copy('https://files.slack.com/files-tmb/T1Q3K1TFB-F6TQMM6AG-baba978dff/image003_480.jpg', 'file.jpeg');

echo '<img src="file.jpeg">';
echo '<hr>';

//Get the file
$content = file_get_contents("https://files.slack.com/files-tmb/T1Q3K1TFB-F6TQMM6AG-baba978dff/image003_480.jpg");

//Store in the filesystem.
$fp = fopen("image.jpg", "w");
fwrite($fp, $content);
fclose($fp);
echo '<img src="image.jpg">';
echo '<hr>';

$url_to_image
 = 'https://files.slack.com/files-tmb/T1Q3K1TFB-F6TQMM6AG-baba978dff/image003_480.jpg';

$ch = curl_init($url_to_image);

$my_save_dir = 'images/';
$filename = basename($url_to_image);
$complete_save_loc = $my_save_dir . $filename;

$fp = fopen($complete_save_loc, 'wb');

curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
fclose($fp);
echo '<img src="'.$complete_save_loc.'">';
echo '<hr>';

echo '<hr><img src="https://files.slack.com/files-tmb/T1Q3K1TFB-F6TQMM6AG-baba978dff/image003_480.jpg">';
echo '<hr><img src="https://files.slack.com/files-tmb/T1Q3K1TFB-F6TQMM6AG-baba978dff/image003_360.jpg">';
echo '<hr><img src="https://conversazioniconmario.slack.com/files/U1Q37UCNL/F6TQMM6AG/image003.jpg">';

?>

wget也被愚弄了;

wget -nd -r -P /myLocalPath/images  -A jpeg,jpg,bmp,gif,png https://files.slack.com/files-tmb/T1Q3K1TFB-F6TQMM6AG-baba978dff/image003_480.jpg

解决方法:

您也可以通过提供权利headers下载文件：

 wget -d --header="Authorization: Bearer A_VALID_TOKEN" https://files.slack.com/files-pri/T1Q3K1TFB-F6TQMM6AG-baba978dff/download/image003.jpg
