Javascript 如何修复'；localhost拒绝连接'；来自VS代码？

我正在VS代码中处理一个VUE项目，并尝试使用“Chrome（预览）”，这是默认配置文件：

{
    // 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": "pwa-chrome",
            "request": "launch",
            "name": "Launch Chrome against localhost",
            "url": "http://localhost:8080",
            "webRoot": "${workspaceFolder}"
        }
    ]
}

不确定是否需要更改这些内容？这类东西的新手，请告诉我
