如何让快速应用程序从外部重定向 API 调用运行获取路由

问：

我正在使用 MERN 应用程序授权我的 QuickBooks 帐户使用他们的 API 调用。

app.get("/api/quick-books/authorize", async (req, res, next) => {
    try {
      const authUri = oauthClient.authorizeUri({
        scope: [OAuthClient.scopes.Accounting],
        state: "intuit-test",
      });
      res.send(authUri);
    } catch (error) {
      next(error);
    }
  });

  app.get("/api/quick-books/authorize-callback", async (req, res, next) => {
    try {
      const parseRedirect = req.url;
      oauthClient
        .createToken(parseRedirect)
        .then((authResponse) => {
          oauthClient.setToken(authResponse.token);
          const newQuickBookToken = new QuickBookToken({
            realmId: authResponse.token.realmId,
            refreshToken: authResponse.token.refresh_token,
          });
          newQuickBookToken.save();
          return res.send("Connected to quick books please close this window");
        })
        .catch((e) => {
          throw e;
        });
    } catch (error) {
      next(error);
    }
  });

当我在localhost上执行此操作时，它完全按预期工作。但是当我在我的暂存环境（使用 Heroku）上时，在我连接到 QuickBooks 后，/api/quick-books/authorize-callback 路由永远不会被调用，而只是在根域 /

以下是我的服务器的设置方式

const path = require("path");
const express = require("express");
const cors = require("cors");
const db = require("./DB/conn");
db.on("error", console.error.bind(console, "MongoDB connection error:"));

const PORT = process.env.PORT || 5000;
const app = express();

app.use(cors());
app.use(express.urlencoded({ extended: true }));
app.use(express.json());

app.use((req, res, next) => {
  if (process.env.NODE_ENV === "production") {
    if (req.headers["x-forwarded-proto"] !== "https")
      return res.redirect("https://" + req.headers.host + req.url);
  }
  next();
});
require("./routes")(app);

app.use(express.static(path.resolve(__dirname, "../client/build")));

app.get("*", (req, res) => {
  res.sendFile(path.resolve(__dirname, "../client/build", "index.html"));
});

if (process.env.NODE_ENV !== "test")
  app.listen(PORT, () => {
    console.log(`Server listening on ${PORT}`);
  });

module.exports = { app };

我厌倦了从 QuickBooks 重定向触发我的 get 路由，但它只有在本地计算机上运行时才有效。
