javascript – 渲染EJS模板并将其另存为文件

作者:互联网

我一直在讨论这个,我试图渲染一个EJS文件并将结果保存为HTML,保存部分似乎正在工作,但我无法全面了解如何从’返回数据模板’文件.

var fileName = 'public/cv/' + userID + '_default.html';
    var stream = fs.createWriteStream(fileName);
    function buildHtml(request) {

        var sveducations = JSON.parse(SQReducations);
        var header = '';

        return '<!DOCTYPE html>'
            + '<html><header>' + header + '</header><body>' +
                html
            +
            '</body></html>';
    };
    stream.once('open', function (fd) {
        var html = buildHtml();
        stream.end(html);
    });

解决方法:

这是保存从ejs呈现的html字符串的最简单方法.

var ejs  = require('ejs');
var fs   = require('fs');
var data = {} // put your data here.  

var template = fs.readFileSync('./template.ejs', 'utf-8');
var html     = ejs.render ( template , data );

fs.writeFileSync("./html.html", html, 'utf8');

如果要从JSON文件中读取数据

var data = JSON.parse(fs.readFileSync('./data.json', 'utf8'));

使用try catch获取错误消息.

var ejs  = require('ejs');
var fs   = require('fs');
var data = {} // put your data here.  

try {
    var template = fs.readFileSync('./template.ejs', 'utf-8');
    var html     = ejs.render ( template , data );

    fs.writeFileSync("./result.html", html, 'utf8');

}catch (e){
    console.log(e)  // If any error is thrown, you can see the message.
}
