【问题描述】：

我正在尝试制作一个电子应用程序，用户可以在其中选择“托管私人服务器”或“加入私人服务器”。这样，用户可以与主机或其他用户交换消息，或者创建一个其他人可以加入的房间

当我的代码在 main.js（电子应用程序运行的地方）上时，服务器生成没有问题。但是当我尝试将相同的代码放在 Server.js 中并在 html 文件中引用它时（使用

C:\Users\lages\Desktop\Pasta du apepe\electron-quick-start\node_modules\depd\index.js:413 Uncaught EvalError: Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an以下内容安全策略指令中允许的脚本来源：“script-src 'self' 'unsafe-inline'”

知道如何解决这个错误吗？

我的代码

let ligar_desligar = document.getElementById("botao3")
let statusServer= false 
const expresso= require("express")
var limpador = require("string-sanitizer");
const appe = expresso()
const httpServer = require("http").createServer(appe);
const options ={  
}
const io = require("socket.io")(httpServer, options);
appe.use(expresso.static(__dirname+"/data"))
httpServer.listen(8889, ()=>console.log("adm online na porta http://localhost:8889"))
//SERVER EVENTS SECTION
io.on("connection", (socket) => { 
    console.log("nova conexao, o cara conectado e ID: ", socket.id)
    socket.on("manda", (arg) => {
        limpeza(arg)
        console.log("recebi: ",arg); // world
        socket.broadcast.emit("devolve", arg)
        socket.emit("devolve", arg)
    });
})
function limpeza(palavra){
    limpador.sanitize.keepSpace(palavra); // abcdefgh123
}

标签： javascript node.js electron socket.io-1.0

【解决方案1】：

问题解决了，我只需要添加

meta http-equiv="Content-Security-Policy" content="default-src 'self'; style-src 'self'; script-src 'self' 'unsafe-eval'"

在 html 的元标记中
