如何在sailsjs中获取文档根目录？

Question

To read a file located in the document root of the sails project I currently use an absolute path.

/var/www/project/file.conf

How can I get the document root path in sails? Or how can I read the file in a controller by using relative path?

Answer 1

在Sails中，根路径是：sails.config.appPath

Answer 2

由于主应用程序文件是根文件夹中的app.js ，因此process.cwd()应该可以正常工作。

Answer 3

To extend what @Maciej Maczor Kaczorowski posted...

var path = require('path').resolve(sails.config.appPath, 'file.conf');

or

var path = require('path').resolve(".", 'file.conf');

or

var path = require('path').resolve('file.conf');

or

var path = sails.config.appPath + 'file.conf';

or

var path = res.baseUrl + 'file.conf';
