使用数组循环连接内容

Question

我正在开发一个 Bixby 胶囊，让用户可以访问免费和付费内容 "packs"。每个包都是一个存储在 content/ 目录中的文件。我想遍历这些文件并将它们读入一个名为 entitled_content.

的变量中

我从事实胶囊开始，它使用实用函数搜索名为 content.js 的本地文件。

const CONTENT = []
const literature = require("../content/literature")
const enhanced = require("../content/enhanced")
const roosevelt = require("../content/roosevelt")
const ambition = require("../content/ambition")
const chaucer = require ("../content/chaucer")
//const GET_REMOTE = require('./lib/getRemoteContent.js')

var console = require('console')
console.log(roosevelt)
console.log(ambition)
console.log(chaucer)
const entitlements = ["roosevelt", "ambition", "chaucer"]

var entitled_content = []
entitlements.forEach(function (item) { 
  entitled_content = entitled_content.concat(item)
  console.log(item); })

console.log(entitled_content)

它的作用是这样的：

[ { tags: [ 'roosevelt' ],
    text: 'Happiness is not a goal; it is a by-product. --Eleanor Roosevelt',
    image: { url: 'images/' } } ]
[ { tags: [ 'ambition' ],
    text: 'Ambition is but avarice on stilts, and masked.  --Walter Savage Landor' } ]
[ { tags: [ 'literature' ],
    text: 'A man was reading The Canterbury Tales one Saturday morning, when his wife asked What have you got there?  Replied he, Just my cup and Chaucer.' },
  { tags: [ 'literature' ],
    text: 'For years a secret shame destroyed my peace-- I\'d not read Eliot, Auden or MacNiece. But now I think a thought that brings me hope: Neither had Chaucer, Shakespeare, Milton, Pope. Source: Justin Richardson.' } ]
roosevelt
ambition
chaucer
[ 'roosevelt', 'ambition', 'chaucer' ]

我想要它做的是 assemble 这三个文件 roosevelt、ambitio 和 chaucer 到一个数组变量 entitled_content 中，然后由实用程序函数进行搜索。错误的是这一行 entitled_content = entitled_content.concat(item) 没有做我想要它做的事情，即获取名为 "item".[= 的文件的全部内容12=]

Answer 1

因为您将变量名用引号括起来，所以程序将它们作为字符串读取。

从

更改

const entitlements = ["roosevelt", "ambition", "chaucer"]

到

const entitlements = [roosevelt, ambition, chaucer]

使用数组循环连接内容

concatenate content using loop over array
