Sails Js阅读上传的文件内容 [英] Sails Js Read uploaded file content

问题描述

我想从上传的文件中获取内容.上传的文件只是文本文件，我想逐行读取此文件

I want get content from my uploaded file. Uploaded file is just text file and i want read this file line by line

req.file("model").upload(function (err, uploadedFiles){
  if (err) return res.serverError(err);

  return res.json({
    message: uploadedFiles.length + ' file(s) uploaded successfully!',
    files: uploadedFiles,
    content: uploadedFiles[0] // I want to get my uploaded file content
                              // Stream or buffer
  });

});

推荐答案

首先为Sails.js/Waterline安装本地文件系统流二进制适配器

First install Local filesystem streaming binary adapter for Sails.js / Waterline

npm install sails-local-fs

在您的代码中创建fs实例

in your code create fs instance

var fs = require('fs');

现在使用readFile()方法获取文件的内容

And now use readFile() method to get content of your file

fs.readFile(files[0].fd, 'utf8', function (err,data) {
    return res.json(200, {message: 'Ok', data: data});
  })
