页面刷新后 Angular4 cli 路由不起作用？

Question

如果我在弹出 webpack 之前尝试路由，它会按预期工作。一旦执行 ng eject，应用程序就会编译并运行，但路由器不工作。第一个呼叫已正确路由，但如果您尝试刷新或导航到其他路由，应用程序 returns 无法 /GET 路由。

我正在使用最新的 angular cli 4.0.0

const entryPoints = ["inline","polyfills","sw-register","scripts","styles","vendor","main"];

尝试添加 devServer 选项：

module.exports = {
    "devtool": "source-map",
    ...
    devServer: {
        historyApiFallback: true
    }
};

来自文档

If you are using the HTML5 history API you probably need to serve your index.html in place of 404 responses, which can be done by setting historyApiFallback: true

https://webpack.github.io/docs/webpack-dev-server.html#the-historyapifallback-option

你也可以看看angular-cli如何配置devServer选项
