我可以在同一条路线上使用2种不同的功能吗？ Node.js的

I have 2 different methods that I want to be called when a specific form is filled. I know that I can't have a form with 2 actions so I am just wondering can I call 2 different methods on the same route in Node.js?

在填写特定表单时，我想要调用两种不同的方法。我知道我不能有一个带有2个动作的表单所以我只是想知道我可以在Node.js中的同一路径上调用2种不同的方法吗？

I need something like this

我需要这样的东西

router.post('/webmark/addcollection', webmarks.addCollection);
router.post('/webmark/addcollection', webmarks.uploadPicture);

so basically when the button in the form is pressed, the action would redirect to the specific route and the 2 methods would be called.

因此，当按下表单中的按钮时，操作将重定向到特定路径，并且将调用2个方法。

3 个解决方案

#1

You can just put the uploadPicture inside the addCollection and it will work as you want.

您可以将uploadPicture放在addCollection中，它可以根据需要使用。

#2

No, if do it that way, then you will be overwriting the first.

不，如果这样做，那么你将覆盖第一个。

A better approach to that is like below:

更好的方法如下：

router.post('/webmark/addcollection', webmarks.addCollection, webmarks.uploadPicture);

And make sure you make the call to next middleware function here uploadPicture from addCollection handler by adding next() in addCollection middleware on the successful operation.

并确保通过在成功操作的addCollection中间件中添加next（），从addCollection处理程序中调用下一个中间件函数uploadPicture。

exports.addCollection = function(req, res, next){
  // You logic goes here
  // On success operation call next middleware

  next();
}

exports.uploadPicture = function(req, res){
  // You logic for uploadPicture
}

#3

Your first function receives 3 input (request, response, next), at the end of this function, call next().

您的第一个函数接收3个输入（请求，响应，下一个），在此函数结束时，调用next（）。
