html - 使用 Heroku 构建成功，但应用程序错误

Question

请允许我解释一下。我使用 Heroku 来启用我的在线应用程序 (React/Redux)。

所以，我的构建已经正确完成，但是当我查看时log我发现了这个错误：

at=error code=H10 desc="App crashed" method=GET path="/favicon.ico" host=desolate-river-47144.herokuapp.com request_id=334501ef-1403-4ba3-a69e-3587b44dd79c fwd="xx.xxx.xx.xx" dyno= connect= service= status=503 bytes= protocol=https

（fwd包含我的 IP 地址）

我只有这个错误。我试过heroku restart了，但问题仍然存在。

我所有的日志如下。如你所见，一切都已建成——这就是我不明白的。

Answer 1

我最好的猜测是你的服务器没有监听 Heroku 期望它监听的端口。

这两行日志表明这对我来说可能是这种情况，特别是因为在第一行之前，自进程上次记录任何内容以来，大约有 30 秒的间隔。

2018-05-20T17:06:46.501296+00:00 heroku[router]: at=error code=H20 desc="App boot timeout" method=GET path="/" host=desolate-river-47144.herokuapp.com request_id=e8a9dd79-4bce-4701-ba86-59b43014372f fwd="77.144.48.66" dyno= connect= service= status=503 bytes= protocol=https

2018-05-20T17:07:06.686809+00:00 heroku[web.1]: Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of launch

无论您在哪里设置服务器侦听的端口，请尝试执行类似的操作const port = process.env.PORT || 3000
