Question

我在网站上有一个curl脚本，它使用CURL向服务器发出请求。另一方面，我使用wkhtmltopdf生成带有HTML的PDF，这在网站上未启用https时工作正常，但是一旦启用https，PDF genetation就会抛出错误。

MY curl script

$url = Yii::app()->params['pdfUrl']; //Equals http://xxx.xx.xxx.xxx/server/?r=pdf/generatePdf

            $body = array(
                "client_url"=>Yii::app()->params['pdfClientURL'],
                "client_id"=>Yii::app()->params['pdfClientID'],
                "title"=>urlencode($title),
                "content"=>urlencode(($content))

            );
            foreach($body as $key=>$value) { $body_str .= $key.'='.$value.'&'; }
                rtrim($body_str,'&');

            curl_setopt ($c, CURLOPT_POST, true);
            curl_setopt ($c, CURLOPT_POSTFIELDS, $body_str);

            curl_setopt ($c, CURLOPT_RETURNTRANSFER, true);
            $pdf = curl_exec ($c);

            curl_close ($c);
            header("Content-Type: application/pdf");
            header("Cache-Control: no-cache");
            header("Accept-Ranges: none");
            header("Content-Disposition: attachment; filename=".str_replace(' ', '_', $title).".pdf");
            echo $pdf;
            Yii::app()->end();

https导致的是什么？

我遇到错误WKHTML2PDF

Answer 1

好的，在@Keeyai指出我正确的方向后发现问题。我设法找到这篇文章http://code.google.com/p/wkhtmltopdf/issues/detail?id=17&q=ssl并在服务器上安装了openssl-devel，其中安装了wkhtml2pdf并解决了问题。由于问题是由使用https链接的图像引起的

yum install openssl-devel做了这个伎俩

Answer 2

查看the curl_setopts page。

像CURLOPT_SSL_VERIFYPEER = false之类的东西可能会有所帮助。

在与ssl相关的各种选项中查看该页面 - 确保您在那里找到答案...
