节点表示如何将句柄html页面呈现给文件 [英] node express how to render handlebars html page to file

问题描述

我想通过wkhtmltopdf将一些html页面转换为pdf。但是，我要转换为pdf的html页面是使用handlebars动态生成的。

I want to convert some html page to pdf via wkhtmltopdf. However, the html page I want to convert to pdf is dynamically generated using handlebars.

所以我认为一个解决方案可能是通过handlebars生成html页面，但是一个文件（html文件）。然后，使用hkhtmltopdf将该文件转换为pdf，然后允许用户以某种方式下载pdf。

So I think one solution maybe to generate the html page via handlebars but to a file (html file). Then, convert that file to pdf using hkhtmltopdf, then allow the user to, somehow, download the pdf.

所以，我的问题是：如何将（handlebars）动态生成的html页面呈现给文件？

So, my question is: how can I render the (handlebars) dynamically generated html page to a file?

感谢和再见...

推荐答案

文件。

var Handlebars = require('handlebars');

var source = "<p>Hello, my name is {{name}}. I am from {{hometown}}. I have " +
    "{{kids.length}} kids:</p>" +
    "<ul>{{#kids}}<li>{{name}} is {{age}}</li>{{/kids}}</ul>";
var template = Handlebars.compile(source);

var data = { "name": "Alan", "hometown": "Somewhere, TX",
    "kids": [{"name": "Jimmy", "age": "12"}, {"name": "Sally", "age": "4"}]};
var result = template(data);


var fs = require('fs');
    fs.writeFile("test.html", result, function(err) {
    if(err) {
        return console.log(err);
    }
});
