我正在为我的MERN应用程序使用NPM安装API缓存。我希望我的其中一个请求被缓存，然后当对另一个路由发出请求时，它会刷新缓存（获取新数据）。我已经成功使其中一个请求被缓存，但我无法清除它。
这是我的代码：
```javascript
const apicache = require("apicache");
let cache = apicache.middleware;
app.get("/api/users/checkJWT", cache("2 minutes"), async (req, res) => {
  const token = req.headers.authorization?.split(" ")[1];
  const decoded = jwt.verify(token, SECRET_KEY);
  if (decoded != null && (await User.findById(decoded.id)) != null) {
    return res.status(200).json({ valid: true, user: await User.findById(decoded.id) });
  } else {
    return res.status(400).json({ valid: false });
  }
});
app.patch("/api/users/user", authenticateJWTUser, async (req, res) => {
  apicache.clear('/api/users/checkJWT');
  const user = await User.findOne({ name: req.body.username });
  if (req.body.name != null) {
    user.name = req.body.name;
  }
  if (req.body.email != null) {
    user.email = req.body.email;
  }
  if (req.body.password != null) {
    user.password = await bcrypt.hash(req.body.password, 10);
  }
  if (req.body.tasks != null) {
    user.tasks = req.body.tasks;
  }
  try {
    const updatedUser = await user.save();
    res.json(updatedUser);
  } catch (error) {
    res.status(400).json({ message: error.message });
  }
});

请注意，我只提供了代码的翻译部分，没有包含其他内容。

I&#39;m using NPM install API cache for my MERN application. I want one of my requests to be cached and then when a request is made to another route it refreshes the cache (it fetches the new data). I&#39;ve managed to get one of my requests to be cached but I can&#39;t manage to clear it.
This is my code

I was able to get this work using the [apicache-plus package](https://www.npmjs.com/package/apicache-plus?activeTab=readme). 
```javascript
const apicache = require("apicache-plus");
router.get(
  "/api/users/getName/1",
  apicache.middleware("10 minutes"),
  async (req, res, next) => {
    req.apicacheGroup = "toClear";
    const someData = { someName: "Amy" };
    res.json(someData);
  }
);
router.get("/api/users/user/1/2", async (req, res, next) => {
  console.log("something");
  apicache.clear("toClear");
  const user = { name: "Jeff" };
  res.json(user);
});
