Use PHANTOMJS to generate PDFs in Ruby on Rails

First, the new project

Rails new App--skip-bundle

Modify Gemfile file after completion: Vim Gemfile

Change source to Taobao or Ruby-china.

Add to this file: Gem ' Phantomjs '

Then run: Bundle install

So the project is new and completed.

Second, generate PDF

Create a controller to add require ' PHANTOMJS ' to the head and add a get method for getting the PDF: get_pdf

Add the following code to this method:

Phantomjs.base_dir = "/path/project_name/bin/phantomjs/" #phantomjs将要安装的目录
Phantomjs.run ('/path/project_name/public/generate_pdf.js ')

Send_file ("Public/mypdf.pdf",: filename = "mypdf.pdf",: type = "Application/pdf")

Add the following code to Generate_pdf.js:

var page = require (' webpage '). Create ();
Page.open (' http://www.baidu.com ');
page.onloadfinished = function () {
Page.render (' public/mypdf.pdf ');
Phantom.exit ();
}

Third, the operation

Start Service: Rails s

Enter http://localhost:3000/controller/get_pdf in the address bar

The first time this method is requested, it installs the directory Phantomjs to/path/project_name/bin/phantomjs/.

Once the installation is complete, you can see the PDF that you saved:

　　

So this is a success.

Note: This exported PDF does not contain background and background images in CSS styles.
