我试图从外部源转换图像到base64，下面是我的尝试

$imgsrc = file_get_contents('mydomain.com/assets/img/logo.png');
return response()->json([ 'img' => base64_encode($imgsrc) ]);

字符串
下面是输出，

如果你想显示图像，试试这个

$imageData = "/9j/4AAQSkZJRgABAQEAYABgAAD........";//base64_encode strong
echo '<img src="data:image/gif;base64,' . $imageData . '" />';

字符串
或

$code_base64 = $row['content'];//base64_encode strong
$code_base64 = str_replace('data:image/jpeg;base64,','',$code_base64);
$code_binary = base64_decode($code_base64);
$image= imagecreatefromstring($code_binary);
header('Content-Type: image/jpeg');
imagejpeg($image);
imagedestroy($image);
