我的 express 應用程式在 localhost 上運行良好，但在 Heroku 上無法運行。當我添加一行時，它停止作業并且
這條線是
app.use("/api/product", require("./routes/product"))
這是代碼 Index.js
const express = require("express");
const app = express();
const port = process.env.PORT || 5000;
app.get("/", (req, res) => {
res.send("responded")
});
app.use(express.json())
app.use("/api/product", require("./routes/product"))
app.listen(port, () => {
console.log(`Example app listening at http://localhost:${port}`);
});
產品.js
const express = require("express");
const router = express.Router();
router.get("/", async (req, res) => {
try {
res.json({
status: 200,
message: "Data has been successfully fetched"
});
}
catch (error) {
console.log(error);
return res.status(400).send("server error")
}
})
module.exports = router;
包.json

你會想切換你的路線處理程式的地方。否則，您將永遠不會豐富您的 api，因為第一個會捕獲所有請求。
const express = require("express");
const app = express();
const port = process.env.PORT || 5000;
app.use(express.json())
app.use("/api/product", require("./routes/product"))
app.get("/", (req, res) => {
res.send("responded")
});
app.listen(port, () => {
console.log(`Example app listening at http://localhost:${port}`);
});
