CakePdf正在使用的Windows和php proc__open上的一个巨大问题是二进制中的空格，中的异常只是返回一条通用消息，而不是发生的错误 在/WkHtmlToPdfEngine.php上#L36使用内容['stderr]进行扩展以查看真正的错误：
throw new CakeException("WKHTMLTOPDF didn't return any data. Returned Error: ".$content['stderr']);

'binary'=> 'C:\\Progra~1\\wkhtmltopdf\\wkhtmltopdf.exe'
嘿，我面临着完全相同的问题。但这种解决方案对我不起作用。你能告诉我是否有其他方法可以尝试吗？你也可以检查一下你是否在php中启用了proc_open函数。一些主机出于安全原因禁用了它。2年后，再次面临这个问题，并使用本文解决了它。这对我很有用，谢谢！Windows/Wamp上的CakePHP 2.7和CakePDF 1.02
