javascript - Node js 需要使用变量 (var) 的 json

Question

我想要求./../bin/<variable>.json 。所以我将 var 设置为 var (reqLink = "'./../bin/"+lanID+".json'")并传递至(var engJason = require(reqLink))但没有成功。但它确实适用于像这样的相对路径 (var engJason = require('./../bin/eng.json');)

var reqLink = "'./../bin/"+lanID+".json'";
var engJason = require(reqLink);

//Not working ||error Cannot find module ''./../bin/eng.json''

Answer 1

删除多余的单引号:

"'./../bin/"+lanID+".json'" => "./../bin/"+ lanID + ".json"
