如何在nodejs的根文件夹之外上传文件？

Question

I have my project folder on Ubuntu instance at: /workspace/myproject

Till now, I used to store uploaded files at location: /myproject/public/uploads

var fs = require('fs');
var savePath = 'public/uploads/';
var filename = uuid.v4() + '.jpg';
var base64 = new Buffer(requestParams[constant.DATA], 'base64');
fs.writeFile(savePath + filename, base64, function(error) {
});

I want to save my uploaded files at: /workspace/uploads

instead of inside the public folder. Also, I don't want to write absolute path in my code.

Any other idea?

Answer 1

If you want to save a file in a folder within the parent directly, then you could use ../ to go back a level. Like this:

var fs = require('fs');
var savePath = __dirname + '/../uploads/';
var filename = uuid.v4() + '.jpg';
var base64 = new Buffer(requestParams[constant.DATA], 'base64');
fs.writeFile(savePath + filename, base64, function(error) {
    // handle error
});

您可以使用__dirname获取当前目录或./相对路径
