使用Heroku部署时出现问题(错误504)
我正在部署一个非常小的React App + Node服务器来测试Heroku的部署，
I'm deploying a very small React App + Node server to test deployment with Heroku,
我可以获取客户端，但不能获取服务器
I can get the client but not the server,

网站: https://test-ofilms-heroku.herokuapp.com/
在控制台中，出现504错误
In the console, there's a 504 error
Failed to load resource: the server responded with a status of 504 (Gateway Timeout)
xhr.js:166 GET https://test-ofilms-heroku.herokuapp.com/api/message 504 (Gateway Timeout)
您知道我必须添加什么来纠正此504错误吗?
Do you know what I have to add to correct this 504 error ?
花点时间看一下您的仓库.不是setupProxy.js，而是设置API的方式.
Got some time to take a look at your repo. It's not the setupProxy.js, but instead it's how you've set up your API.
第一期:您正在尝试为开发中的生产资产提供服务.
First issue: You're trying to serve production assets in development.
app.use(express.static(path.join(__dirname, "build")));
app.get("*", (req, res) => {
res.sendFile(path.join(__dirname, "build", "index.html"));
});
修复:在生产中，如果请求的路由不匹配，它将捕获请求并回退到客户端index.html.
Fix: When you're in production, it'll capture requests and fallback to the client index.html if a requested route doesn't match.
if (process.env.NODE_ENV == "production") {
app.use(express.static(path.join(__dirname, "build")));
app.get("*", (req, res) => {
res.sendFile(path.join(__dirname, "build", "index.html"));
});
}
第二个问题:在提供API路由之前，您将上述资产作为通配符/(更改为*).换句话说，它永远不会到达您的GET请求的API路由，因为/(*)首先捕获了所有GET请求.
Second issue: You're serving the above assets as a wildcard / (changed to *) before you're serving your API routes. In other words, it'll never reach your GET requested API routes since / (*) catches all GET requests first.
修复:您的所有API路由都必须位于客户端生产版本之上-这样，请求首先流经API，然后再回退到客户端.
Fix: All of your API routes must sit above your client production build -- this way, requests flow through the API first and then fallback to the client second.
app.get("/api/message", (req, res) => {
res.json({ message: "Test déploiement d'O'Films sur Heroku" });
});
app.get("/api/hello", (req, res) => {
res.json({ message: "Hello world !" });
});
if (process.env.NODE_ENV == "production") {
app.use(express.static(path.join(__dirname, "build")));
app.get("*", (req, res) => {
res.sendFile(path.join(__dirname, "build", "index.html"));
});
}
app.listen(port, () => {
console.log(`Server is on up ${port} now !`);
});
