我正在运行一个express.js应用程序,其中我有一个返回json对象的路由
https://serene-depths-3284.herokuapp.com/chapters?setLng=en-UK
在我的控制器文件夹中,我有chapters.coffee文件,如下所示
# Return the chapters.json based on the language
i18n = require "i18next"
fs = require "fs"
cldr = require "cldr"
__ = require "underscore"
exports.chapters = (req, res, err) ->
fs.readFile "./data/chapters.json", (err, chapterJSON) ->
console.log("read file error", err) if err
tzmChapters = JSON.parse chapterJSON
try
# ...
lngCode = req.query.setLng.split("-")[0]
catch e
# fallback to user locale
lngCode = i18n.lng().split("-")[1]
allCountries = cldr.extractTerritoryDisplayNames(lngCode)
tzmNetwork = []
tzm = __.each tzmChapters, (value, index, list) ->
locale = value.desc.LOCALES.split("-")[1]
tzmNetwork.push({link:value.desc.WEBSITE,contact:value.desc.CONTACT,country: allCountries[locale]})
res.json {tzmNetwork}
可以在https://github.com/TZM/tzm-blade/blob/master/app/controllers/chapters.coffee
找到代码为什么我尝试从不同的站点访问章节json文件,我得到:
XMLHttpRequest cannot load http://localhost:3000/chapters. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:8000' is therefore not allowed access.
我如何在我的代码中启用它,并且有更好的方法来执行此操作,因为我也在footer.blade文件中使用它,我也在我的apps.coffee文件中读取了chapters.json文件{{3 }}
非常感谢任何建议。
