A summary of the experience of converting Web pages to PDF using Wkhtmltopdf __html

Recent projects need to do an online contract function, the contract has electronic version, the need to put the web version of the contract directly production of PDF, the requirements of the style can not be disorderly, there are page numbers have headers and footers, and so on, online search for a period of time, found a tool called: wkhtmltopdf , This should be a foreign free software, there is a windows,mac,linux version, directly in the command line calls, these days completed a demo, incidentally summed up.

This is the tool's official website: the tools required by http://wkhtmltopdf.org/downloads.html can be downloaded here, free of charge.

March 7, 2017 15:49:58 as if the tool could not parse angularjs ...
Put the demo code first:

Calling class:

Package wkhtmltopdf;
Import Java.io.File;

Import Java.util.Date;
 /** * Created by Jerry in 2017/2/13. * God Bless Me * * public class Wkhtmltopdf {//wkhtmltopdf path in system private static final String Topdftool = "c:\\

        public static void Main (string[] args) {Date date = new Date ();
        String fileName = string.valueof (Date.gettime ()) + ". pdf";
    Convert ("Http://www.jianshu.com/p/74e3a6ee4ae8", "d:\\pdf\\" + fileName); /** * HTML to PDF * * * @param srcpath HTML path, can be the path on the hard disk, can also be network path * @param destpath PDF Save Path * Return conversion successfully returns TRUE */public static Boolean convert (String Srcpath, String destpath) {File File = new Fil
        E (DestPath);
        File parent = File.getparentfile ();
        If the PDF save path does not exist, create the path if (!parent.exists ()) {parent.mkdirs ();
} StringBuilder cmd = Getformal ();

       StringBuilder cmd = test1 (); The HTML path is the target page path Cmd.append ("");
        Cmd.append (Srcpath);
        Cmd.append ("");

        PDF Save Path Cmd.append (DestPath);
        Boolean result = true;
            try {Process proc = runtime.getruntime (). EXEC (cmd.tostring ());
            Htmltopdfinterceptor error = new Htmltopdfinterceptor (Proc.geterrorstream ());
            Htmltopdfinterceptor output = new Htmltopdfinterceptor (Proc.getinputstream ());
            Error.start ();
            Output.start ();
        Proc.waitfor ();
            catch (Exception e) {result = false;
        E.printstacktrace ();
    return result; /** * Standard Format * * @return/public static StringBuilder Getformal () {StringBuilder
        cmd = new StringBuilder ();
        Wkhtmltopdf path Cmd.append (topdftool) in the system;

        Cmd.append (""); Cmd.append ("--header-line");//The line below the header//Cmd.append ("--footer-line");//footer above line Cmd.append ("--footer-center [Page]/[topage]"); Place page number//Cmd.append in the footer Center ("--header-right here is the header of our system"); Place the text cmd.append in the middle of the header ("--header-html http://localhost:8090/myheader.html"); In the middle of the header place picture Cmd.append ("--header-spacing 5");//(Set the distance between header and content, default 0) cmd.append ("--margin-top 20mm");
        Sets the top margin of the page (default 10mm) cmd.append ("Cover http://localhost:8090/firstPage.html");
    return cmd;
        public static StringBuilder Test1 () {StringBuilder cmd = new StringBuilder ();
Wkhtmltopdf path Cmd.append (topdftool) in the system;
        Cmd.append ("--cover http://localhost:8090/firstPage.html");
        Cmd.append ("T 15mm");
        Cmd.append ("--header-spacing 5");
        Cmd.append ("--outline");
        Cmd.append ("Cover http://image.baidu.com");

        Cmd.append ("");
    return cmd; }
}

Tool Class:

Package wkhtmltopdf;

/**

 * God Bless Me * *
import java.io.BufferedReader;
Import java.io.IOException;
Import Java.io.InputStream;
Import Java.io.InputStreamReader;

/**
 * When Java calls Wkhtmltopdf, to get the content returned by wkhtmltopdf/public
class Htmltopdfinterceptor extends Thread {
    private InputStream is;

    Public Htmltopdfinterceptor (InputStream are) {
        this.is = is;
    }

    public void Run () {
        try{
            inputstreamreader ISR = new InputStreamReader (IS, "utf-8");
            BufferedReader br = new BufferedReader (ISR);
            String line = null;
            while (line = Br.readline ())!= null) {
                System.out.print (line.tostring ());//output Content
            }
        }catch ( IOException e) {
            e.printstacktrace ();}}}

Basically you copy these two classes, install the tool, you can run directly.

Here are a few of my own experiences to explore:
Although I look at a few of the data there is no say command execution has a distinction, but it is obvious that in the generation of the first page, you must
Cmd.append ("Cover http://localhost:8090/firstPage.html");
Write in the end, otherwise it will be an error, if you know the reason, you can contact me qq:527397749
There is also a bit easy to ignore, is the last of each command must add space, otherwise there will be the problem of command adhesion, very basic, it is difficult to find.

A list of commonly used commands is attached;

There is a good article: http://www.jianshu.com/p/4d65857ffe5e Everyone can read together, other materials I think there is nothing to see, because I have read it again.
