尝试使用 Snappy（wkhtmltopdf 包装器）生成 pdf
我正在尝试通过以下代码使用 snappy 生成 pdf：
$snappy = new SnappyPdf;
$snappy->setExecutable('/usr/bin/wkhtmltopdf');
$snappy->save('http://www.google.com', '/tmp/jander.pdf');
在 apache 日志中我发现：
完成加载页面 (1/6) [>
] 0% [======>
] 10% [==========>
] 18% [============>
] 20% [=============>
] 22% [================>>

但未生成 pdf。
有什么想法吗？

I'm trying to generate a pdf using snappy through this code:
$snappy = new SnappyPdf;
$snappy->setExecutable('/usr/bin/wkhtmltopdf');
$snappy->save('http://www.google.com', '/tmp/jander.pdf');
In the apache log i find this:
Done Loading pages (1/6) [>

but the pdf is not generated.
Any idea?

我建议您首先查看
$snappy->save()的返回值。根据代码，如果输出的PDF会返回true文件已创建且文件不为空。您可能还想检查 代码。尝试在您的服务器上手动执行此代码。
I suggest you start by looking at the return value from
$snappy->save(). According to the code, it will return true if the outputted PDF file is created and the file is not empty.You might also want to check the output of
$this->buildCommand($url, $path)on line 37 of the code. Try manually executing this code on your server.使用
$snappy->generate或
$snappy->generateFromHtml($htmlstring, 'path/to/save/file')use
$snappy->generateor
$snappy->generateFromHtml($htmlstring, 'path/to/save/file')
