我已經安裝KNP活潑束與作曲家和隨後在https://github.com/KnpLabs/KnpSnappyBundleKNP活潑束和wkhtmltopdf ContextErrorException
我已經安裝wkhtmltopdf-0.9.9-Installer.exe的用於使用和配置教程和改變默認路徑在該config.yml文件
# knp_snappy Configuration
knp_snappy:
pdf:
enabled: true
binary: C:\Program Files (x86)\wkhtmltopdf
options: []
這裏是功能
/**
* @Route("/print", name="invite_print")
* @Method("GET")
*/
public function printAction() {
$entity = new Invite();
$form = $this->createCreateForm($entity);
$html = $this->renderView('PrifProtocoleBundle:Invite:new.html.twig', array(
'entity' => $entity,
'form' => $form->createView()
));
return new Response(
$this->get('knp_snappy.pdf')->getOutputFromHtml($html), 200, array(
'Content-Type' => 'application/pdf',
'Content-Disposition' => 'attachment; filename="file.pdf"',
'charset' => 'UTF-8',
)
);
}
但unfortunateley我有這些錯誤消息:
錯誤1:
ContextErrorException: Warning: json_encode(): Invalid UTF-8 sequence in argument in C:\wamp\www\protocole\app\cache\dev\classes.php line 4592
錯誤2:
ContextErrorException: Warning: json_encode(): Invalid UTF-8 sequence in argument in C:\wamp\www\protocole\vendor\monolog\monolog\src\Monolog\Formatter\NormalizerFormatter.php line 132
可有人告訴我怎樣做才能解決這個問題呢?感謝
在json.php文件中的函數json_encode(奇怪的空)
/**

function json_encode ($value, $options = 0, $depth = 512) {}
用於錯誤2
protected function toJson($data, $ignoreErrors = false)
{
// suppress json_encode errors since it's twitchy with some inputs
if ($ignoreErrors) {

您好,感謝您的答覆,我已經按照你的意見,掃清了現金,去掉「字符集」 =>從響應,並在我的layout.html.twig「UTF-8」還有就是<元http-equiv =「Content-Type」content =「text/html」charset =「utf-8」>但我仍然有json_encode錯誤信息。我在以前的帖子中添加了更多的代碼與json_encode方法...感謝您的時間 – Albee
我的ide是netbeans我發現我必須添加此行:netbeans_default_options =「 - J-Dfile.encoding = UTF-8」在netbeans 。conf,但錯誤消息仍然... – Albee
@Albee你在哪裏使用json_encode? –
