Question

我目前正在阅读thinkster MEAN教程 - 并且真正开始学习堆栈。我白天忙着建设，一切都很好。我回到家的那一刻，我什么都跑不了。使用npm start时，我可以使用curl GET命令通过API层获取文档，构建本身不会呈现，我得到404.见下文：

如果你能指出我正确的方向，那将是值得赞赏的。

Answer 1

GET / home

为何选择404？

您的index.js路径文件夹中GET上的/home没有任何配置。因此，你得到404。同样，您在GET上也没有为/配置路由。

GET /

您也可以获得404。因此，您需要为这些端点配置路由

router.get('/home', function (req, res) {
    res.send({
        msg: 'hello world from /home'
    });
});

router.get('/', function (req, res) {
    res.send({
        msg: 'hello world from at /'
    });
});
