javascript - 如何在 MVC Core 中 require/reference config.json

Question

这条线在 ASP.NET MVC 5 中工作正常，但现在在 ASP.NET Core MVC 中给我一个错误，我应该如何引用我自己的 json 文件？它只包含一些我想在 gulpfile 中使用的绝对和相对路径。

var gulp = require('gulp'),
    rimraf = require("gulp-rimraf"),
    concat = require("gulp-concat"),
    cssmin = require("gulp-cssmin"),
    uglify = require("gulp-uglify"),
    watch = require('gulp-watch'),
    bs = require("browser-sync").create(),
    less = require("gulp-less"),
    changed = require('gulp-changed'),
    imagemin = require('gulp-imagemin'),
    config = require('./Config.json'), // <--- this line fails (It's line 15)
    urlAdjuster = require('gulp-css-url-adjuster'),
    streamqueue = require('streamqueue');

错误消息:

Failed to run "...\Gulpfile.js"...
cmd.exe /c gulp --tasks-simple
module.js:415
throw err;

显然，加载和解析 JSON 文件的 require() 调用不支持 JSON 文件中的注释。

删除这些注释或使用 plugin支持他们。
