wkhtmltopdfContentNotFoundError,代码1

我正在尝试使用wkhtmltopdf phpwrapper 生成基本的pdf .我也在使用yii框架.

这是我的HTML:

    
    

     
            
test
    

我在wktmltopdf中的设置:

$pdfParams = array(

            'header-html' => $this->tmpHeaderFile->getFileName(),
            'footer-html' => $this->tmpFooterFile->getFileName(),

            'username' => 'myUser',
            'password' => 'myPass',
        );
 $this->pdf = new Pdf($pdfParams);

我得到的错误:
