如何解决“内容安全政策:该页面的设置阻止了http://localhost:8080/favicon.ico("default-src")上资源的加载." [英] How to fix 'Content Security Policy: The page’s settings blocked the loading of a resource at http://localhost:8080/favicon.ico (“default-src”).'

问题描述

我能够连接到服务器并使用get请求显示一些文本.但是，当我休息一会后重新启动服务器时，我被打了这个错误

I was able to connect to my server and use a get a request to display some text. However, when I restarted my server after taking a break, I was hit with this error

Content Security Policy: The page’s settings blocked the loading of a resource at http://localhost:8080/favicon.ico ("default-src").

如果有人可以向我指出正确的方向，那太好了.

If anyone can please point me in the right direction, that would be great.

如果有帮助，我正在使用最新版本的Firefox.

我更改了端口.我现在可以看到我的get请求，但是，我仍然收到错误消息

I changed the port. I can now see my get request, however, I'm still getting the error

const express = require ('express');
const cors = require('cors');

const app = express();

app.use(cors());
const port = 3001;
// was 8080

app.listen(port, () => {
    console.log(`Server is up and listening on port ${port}`);
})

app.get('/', (req, res) => {
    res.send({
        express: 'Your express backend is connected to react'
    })
})

推荐答案

也许与在https端口上运行http有关.尝试使用其他端口或将其转换为https.

maybe it has something to do with running http on https port. Try using another port or converting it to https.
