如何實現html轉換成PDF文件(針對Ubuntu Linux/Debian[其餘os安裝會稍微不同])

1. You can install wkhtmltopdf using apt-get command:
   $ sudo apt-get install wkhtmltopdf
   $ sudo ln -s /usr/bin/wkhtmltopdf /usr/local/bin/html2pdf
     Sample outputs:

    [sudo] password for vivek:

   Reading package lists... Done

   ………

   Setting up wkhtmltopdf (0.9.9-1) ...

    ………

2. How do I use wkhtmltopdf

   In this example, convert out bash for loop page to a pdf file:

   $ html2pdf http://www.cyberciti.biz/faq/bash-for-loop/print/             
   /tmp/bash.for.loop.pdf

   Sample outputs:
   Loading pages (1/6)

   Counting pages (2/6)

   …….

   Done

To view generatedpdf file click here. Verify pdf file, enter:

   $ file /tmp/bash.for.loop.pdf

   Sample outputs:

   /tmp/bash.for.loop.pdf: PDF document, version 1.4

  Use the pdfinfo command to prints the contents of the ‘Info’ dictionary (plus     
  some other useful information) from a Portable Document Format (PDF) file:
   $ pdfinfo /tmp/bash.for.loop.pdf

   Sample outputs:

   Title:          Frequently Asked Questions About Linux / UNIX »    

   Bash For Loop Examples » Print

   Creator:

   Producer:       wkhtmltopdf

   ……….

   PDF version:    1.4

3. How do I see all available options?

  You can see a list of commonly used options, enter:
 wkhtmltopdf --help

(一)參考來源3-留言12

   (二)首先第一步驟
 Download wkhtmltopdf from source and compile it (see the instructions in the     
INSTALL.md file ; you may remove the --recursive option from their git clone line, if you already have Qt 4.8 installed)   

   點選Download wkhtmltopdf from source或是來源4，之後點選INSTALL.md，

   Clone this repository by running the following command:

   git clone --recursive https://github.com/wkhtmltopdf/wkhtmltopdf.git

  (三)之後第二步驟
  Run it inside xvfb, as suggested by masterkorp in the bug report.，參考留言8

xvfb-run wkhtmltopdf

  安裝完xvfb後注意的地方在於(just put xvfb-run before any wkhtmltopdf command.)，讓我們返回步驟二，要改成這樣

$xvfb-run html2pdf http://www.cyberciti.biz/faq/bash-for-loop/print/

  這樣應該就能正常執行了
