app.use(express.static("./client/build"));

// Routes for the Application

app.use("/auth", require("./routes/auth"));
app.use("/api", require("./routes/api"));

app.get("/*", (req, res) => {
  console.log(1);
  res.setHeader("Content-type", "text/html");
  res.sendFile(path.join(__dirname, "client/build/index.html"));
});

app.get("/*/*", (req, res) => {

我使用上面的代码来服务它，在构建时一切都运行良好，但是当我用我的服务器服务文件时，默认的/ route运行得很好，但是/admin/login路由或任何其他路由加载一个空白页面。
