您好,我想向laravel应用添加php代码
从这里:http://php.net/manual/de/function.iptcembed.php
我试图在我的控制器中执行以下操作:
<?php
function iptc($rec, $data, $value)
{
$length = strlen($value);
$retval = chr(0x1C) . chr($rec) . chr($data);
if($length < 0x8000)
{
$retval .= chr($length >> 8) . chr($length & 0xFF);
}
else
{
$retval .= chr(0x80) .
chr(0x04) .
chr(($length >> 24) & 0xFF) .
chr(($length >> 16) & 0xFF) .
chr(($length >> 8) & 0xFF) .
chr($length & 0xFF);
}
return $retval . $value;
}
// Path to jpeg file
$path = 'public\images\test.jpg';
// Set the IPTC tags
$iptc = array(
'2#120' => 'Test image',
'2#116' => 'Copyright 2008-2009, The PHP Group'
);
// Convert the IPTC tags into binary code
$data = '';
foreach($iptc as $tag => $string)
{
$tag = substr($tag, 2);
$data .= iptc_make_tag(2, $tag, $string);
}
// Embed the IPTC data
$content = iptcembed($data, $path);
// Write the new image data out to the file.
$fp = fopen($path, "wb");
fwrite($fp, $content);
fclose($fp);
?>
Note
我想在我的路线中调用该函数:
Route::get('/iptc', 'MetaController@iptc');
但现在它向我显示此错误:
函数App \ Http \ Controllers \ MetaController :: iptc()的参数太少,传递了0个且恰好期望3个
有人知道是什么问题吗?
我可以在laravel中写普通的php吗?
但是我怎么了?
谢谢您的帮助! :)
答案 0 :(得分:1)
答案确实存在
Too few arguments to function App\Http\Controllers\MetaController::iptc(), 0 passed and exactly 3 expected
函数@iptc应该有3个参数,但您却传递了0个参数
因此在您的路线中,您需要更改为
Route::get('/iptc/{rec}/{data}/{value}', 'MetaController@iptc');
,然后在网址框中,您只需将其命名为
urlpath / iptc / foo / bar / doe
因此控制器会将其识别为
$ rec = foo,
$ data =条形
$ value = doe
