使用http://localhost:8000的节点服务器只能在Safari中工作，而不能在Chrome中工作。使用127.0.0.1:8000在Safari和Chrome上均可使用。我感到困惑，为什么在chrome浏览器中无法使用localhost。 在我的终端ping localhost中输入并得到127.0.0.1
在更新到angular 8之前，我的项目运行正常，并且能够在本地主机上运行它。更新后我遇到了一些问题，因此我决定降级到angular7。从那时起，我只能使用IP地址和本地主机运行项目，而只能使用Safari，而不是Chrome。知道有什么问题或如何解决这个问题吗？
server.js
const express = require('express');
const app = express();
const path = require('path');
const mongoose = require('mongoose');
const bodyParser = require('body-parser');
const session = require('express-session');
const mongooseDatabase = require("./server/config/mongoose");
const userRoutes = require('./server/config/routes/users');
const taskRoutes = require('./server/config/routes/tasks');
//Body Parser Middleware
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));
app.use(express.static(__dirname + '/dist/todo'));
app.use(session({
secret:"thisisasecret",
saveUninitialized:true,
resave:false,
cookie: {maxAge:1000}
}))
app.set('trust proxy', 1);
mongoose.connect(mongooseDatabase.database, { useCreateIndex: true, useNewUrlParser:true });
mongoose.connection.on('connected', () => {
console.log("Connected to database " + mongooseDatabase.database);
})
mongoose.connection.on('error', (err) => {
console.log("Database database " + err);
})
app.use('/users', taskRoutes, userRoutes);
taskRoutes(app);
userRoutes(app);
app.all("*", (req,res,next) => {
res.sendFile(path.resolve("./dist/todo/index.html"))
});
app.listen(8000, () => console.log("Running on port 8000"));

一个，如果您的应用程序是 Node JS ：-
从server.js代码中获取似乎您具有Node JS应用程序。不是Angular应用程序。我在这里看不到任何组件。只需按F5键，看看会发生什么？
按F5后，打开镶边并键入http://localhost:8000。它应该从server.js调用get方法。
两个如果您的应用程序是“ Angular ”：-
您能否在Visual Studio代码中将 Chrome调试器作为扩展名添加？
添加后，您可以按F5在Chrome中打开应用程序。
按F5时，它将要求您选择目标Chrome，它将在您的项目中创建launch.js。然后在配置中添加网站网址。
以下是示例。
launch.json
{
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.
// For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
"version": "0.2.0",
"configurations": [
{
"type": "chrome",
"request": "launch",
"name": "Launch Chrome against localhost",
"url": "http://localhost:8000",
"webRoot": "${workspaceFolder}"
}
]
}
尝试一下。希望它可以在您的情况下工作。
