安装好以后需要在系统环境变量变量名为”Path”的后添加:;D:\wkhtmltopdf\bin 也就是你安装的目录。安装好以后重启电脑。
测试使用效果
直接在cmd里输入:wkhtmltopdf http://www.baidu.com/ D:website1.pdf
临时文件在哪儿,你的css就得在哪儿,或者你直接使用相对路径,引用其他文件中的css样式也可以的,最简单的就是把css样式直接写在要转成pdf的html页面中。如果存在样式没有,那就是你的样式路径没有写对,在检查一下就可以了!
解决分页问题
wkhtmltopdf 很好用,但也有些不尽人意。就是当一个html页面很长我需要在指定的地方分页那怎么办呢? wkhtmltopdf 开发者在开发的时候并不是没有考虑到这一点,
wkhtmltopdf 有个很好的方法,就是在那个div的样式后添加一个:page-break-inside:avoid;就ok了。
例如
div{ width:800px; min-height:1362px;margin:auto;page-break-inside:avoid;}
注:html的table中不能用thead,用了后换页会出现两个表头
解决中文乱码问题
将 windows下的字体,例如 c:\WINDOWS\Fonts\simsun.TTF,或者msyh.TTF,或者msyhbd.TTF复制到 Linux系统 /usr/share/fonts 下即可。记住要将扩展名改为了.TTC
例如:将Windows下的字体文件 c:\WINDOWS\Fonts\simsun.ttf,Copy到 /usr/share/fonts/SIMSUN.TTC下
PHP环境中,采用系统调用命令 :
exec("wkhtmltopdf ‘http://www.hywtest.com/xt/bill/MTIzNDU2Nzg5‘ ‘/data/users/MTIzNDU2Nzg5/downloadfile//20170607043855515.pdf‘");
Java中调用:
Runtime.getRuntime().exec("wkhtmltopdf ‘http://www.hywtest.com/xt/bill/MTIzNDU2Nzg5‘ ‘/data/users/MTIzNDU2Nzg5/downloadfile//20170607043855515.pdf‘");
