After installation, you need to add after the system environment variable variable named "Path":;D: \wkhtmltopdf\bin is the directory you installed. Reboot the computer after installation.

Test use effect
Input directly in cmd: Wkhtmltopdf http://www.baidu.com/D:website1.pdf

Where the temp file is, where your CSS will be, or you can directly use a relative path, referencing a CSS style from another file, the simplest is to write the CSS style directly in the HTML page that you want to convert to PDF. If there is no style, it is your style path is not written right, check it!

Troubleshoot paging problems
Wkhtmltopdf is very useful, but it is also somewhat unsatisfactory. is when an HTML page is a long I need to be paged in the specified place. Wkhtmltopdf developers did not take this into account at the time of development,
Wkhtmltopdf a good way to do that is to add one after that Div's style: page-break-inside:avoid; it's OK.
For example

div{width:800px; min-height: 1362px; margin:auto; page-break-inside:avoid;} 
 
  Note: The HTML table cannot be used with THEAD, two headers appear after a page break

Place the fonts under WINDOWS, such as C:\WINDOWS\Fonts\simsun. TTF, or Msyh. TTF, or MSYHBD. TTF is copied to the Linux system/usr/share/fonts. Remember to change the extension to. Ttc
For example, c:\windows\fonts\simsun.ttf,copy a font file under WINDOWS to/usr/share/fonts/simsun. TTC under

In a PHP environment, the system invoke command is used:

EXEC ("wkhtmltopdf ' Http://www.hywtest.com/xt/bill/MTIzNDU2Nzg5 '/data/users/mtizndu2nzg5/downloadfile// 20170607043855515.pdf ' ");

Called in Java:

Runtime. GetRuntime (). EXEC ("Wkhtmltopdf ' Http://www.hywtest.com/xt/bill/MTIzNDU2Nzg5"/data/users/ Mtizndu2nzg5/downloadfile//20170607043855515.pdf ' ");
