tp5 使用 TCPD 扩展 将 html 转换为 pdf , 并且保存 pdf 文件报错:fpen(): remote host file access not supported, file://./parame.pdf
利用 TCPD 生成 html 文件 过程
1. 下载 TCPD 扩展项目跟目录下执行
composer require tecnickcom/tcpdf
2. 控制器测试代码
public function pdf(){
$pdf = new TCPDF(PDF_PAGE_ORIENTATION, PDF_UNIT, PDF_PAGE_FORMAT, true, ‘UTF-8’, false);
$pdf->SetCreator(PDF_CREATOR);
$pdf->SetAuthor(‘Nicola Asuni’);
$pdf->SetTitle(‘TCPDF Example 001’);
$pdf->SetSubject(‘TCPDF Tutorial’);
$pdf->SetKeywords(‘TCPDF, PDF, example, test, guide’);
$pdf->SetHeaderData(PDF_HEADER_LOGO, PDF_HEADER_LOGO_WIDTH, PDF_HEADER_TITLE.’ 001′, PDF_HEADER_STRING, array(0,64,255), array(0,64,128));
$pdf->setFooterData(array(0,64,0), array(0,64,128));
$pdf->setHeaderFont(Array(PDF_FONT_NAME_MAIN, ”, PDF_FONT_SIZE_MAIN));
$pdf->setFooterFont(Array(PDF_FONT_NAME_DATA, ”, PDF_FONT_SIZE_DATA));
$pdf->SetDefaultMonospacedFont(PDF_FONT_MONOSPACED);
$pdf->SetMargins(PDF_MARGIN_LEFT, PDF_MARGIN_TOP, PDF_MARGIN_RIGHT);
$pdf->SetHeaderMargin(PDF_MARGIN_HEADER);
$pdf->SetFooterMargin(PDF_MARGIN_FOOTER);
$pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM);
$pdf->setImageScale(PDF_IMAGE_SCALE_RATIO);
if (@file_exists(dirname(__FILE__).’/lang/eng.php’)) {
require_once(dirname(__FILE__).’/lang/eng.php’);
$pdf->setLanguageArray($l);
}
$pdf->setFontSubsetting(true);
$pdf->SetFont(‘dejavusans’, ”, 8, ”, true);
$pdf->AddPage();
$pdf->setTextShadow(array(‘enabled’=>true, ‘depth_w’=>0.2, ‘depth_h’=>0.2, ‘color’=>array(196,196,196), ‘opacity’=>1, ‘blend_mode’=>’Normal’));
$html = <<<EOD
<h1>Welcome to <a href=”http://www.tcpdf.org” style=”text-decoration:none;background-color:#CC0000;color:black;”>&nbsp;<span style=”color:black;”> 郭艳 </span><span style=”color:white;”>BOSS</span>&nbsp;</a>!</h1>
<i>This is the first example of TCPDF library.</i>
<p>This text is printed using the <i>writeHTMLCell()</i> method but you can also use: <i>Multicell(), writeHTML(), Write(), Cell() and Text()</i>.</p>

EOD;

$pdf->writeHTMLCell(0, 0, ”, ”, $html, 0, 1, 0, true, ”, true);
$filaName = Config::get(‘parame.pdf_ulr’). ‘./example_002.pdf’;

// 保存 pdf 方式一 :
//$count = $pdf->Output($filaName, ‘F’);exit;
$count = $pdf->Output(‘./parame.pdf’, ‘F’);exit;

// 保存 pdf 方式二 :
//$count = $pdf->Output(‘example_001.pdf’, ‘S’);
//file_put_contents(‘./example_001.pdf’,$count);exit;

//$pdf->Output(‘example_001.pdf’, ‘F’);exit;
//$pdf->Output(‘./example_001.pdf’, ‘I’);exit;

// 下载 pdf
//$pdf->Output(‘./example_001.pdf’, ‘D’);
}
就这样执行时:报如下错误信息
看到网上的解决方案:参考资料:https://www.e-learn.cn/conten…
可以使用:
$pdf->Output(__DIR__ . ‘/invoices/Delivery Note.pdf’, ‘F’);
我发现的问题是 fopen() 函数打开文件或者 URL。如果打开文件:则必须是 该文件的 绝对路径
ok 问题解决!!!!!
