我正在生成pdf文件，但未生成文件，但是由于我做了作曲家更新（从symfony 4.2.4到4.2.5），因此出现以下错误
未创建文件'generated / pdf /Mon_Beau_Chateau_Roi_Des_Fôrets_Su-Per_04-2019_8ddb3a64c4.pdf'（命令：/ var / www / html / gestImmo / bin / wkhtml2pdf --lowquality'/tmp/knp_snappy5ca4ac7.2a32d。生成/pdf/Mon_Beau_Chateau_Roi_Des_Frets_Su-Per_04-2019_8ddb3a64c4.pdf'）。
我看了日志，没有发现问题：

这是控制器

这是我的服务：

$rentRelease->setPdf($fileName);
$this->manager->persist($rentRelease);
$this->manager->flush();
}
}
有人有想法吗？
答案 0 :(得分：0)
好的，问题是因为我选择的名称具有特殊字符
所以我在服务中添加了一个私有函数，我不知道哪种最干净的方法：
