javascript - 内部服务器错误 Node js

Question

我目前正在设置 Heroku 部署。在本地运行时一切正常，但我从 Heroku 收到以下错误。

我相信这与文件路径有关。我目前在基本目录(即project/)中拥有所有内容，因此正在使用以下内容。

app.use(express.static(path.join(__dirname, '/')));
app.set('views', __dirname);

这是我的一些获取请求

app.get('/', function(req, res) {
    res.render('index.html'); 
});

app.get('/browsePage', function(req, res) {
    res.render('browsePage.html'); 

});

感谢您提前提供的帮助。

您无法在 node.js 中渲染 html 页面。您可以尝试发送 html 文件:

app.get('/', function(req, res) {
   res.sendFile('index.html'); 
});

app.get('/browsePage', function(req, res) {
   res.sendFile('browsePage.html'); 
});
