如何为具有参数和关系的方法编写远程挂钩 [英] How to write remote hook for a method with parameter and relation

问题描述

我经历了远程挂钩文档，我可以成功创建远程钩子，用于没有额外参数的方法，例如login， 这是:

I went through the remote hook documentation, I can successfully create remote hooks for methods without extra parameters, like login, which is:

customer.afterRemote('login', function(ctx, modelInstance, next) {
      if (ctx.result) {
          ...
          next();
      }
      else{
          next();
      }
    });

现在，如何为方法写一个远程钩子:

Now, How to write a remote hook for a method say :

GET /customers/{id}

POST /customers/{id}

或 同时发布相关对象，例如

or while posting related objects like

POST /customers/{id}/contacts
GET /customers/{id}/contacts

我知道对POST /customers/{id}/contacts执行以下操作:

I know doing the following with POST /customers/{id}/contacts:

customer.beforeRemote('**', function(ctx, user, next) {
  console.log(ctx.methodString, 'was invoked remotely'); // customers.prototype.save was invoked remotely
  next();
});

将返回名为的方法的名称，例如:

would return the name of the method called like:

customer.prototype .__ create__contacts被远程调用

customer.prototype.__create__contacts was invoked remotely

但是我仍然无法具体挂钩，并且以下尝试均无济于事，并且无法实现挂钩:

But I am still unable to hook it specifically, and following tries are to no avail, and hook isn't being reached:

customer.beforeRemote('customer.prototype.__create__contacts', function(ctx, user, next)

customer.beforeRemote(customer.prototype.__create__contacts, function(ctx, user, next)

推荐答案

发现了！答案就在此处

首先要使用我刚才提到的customer.beforeRemote('**', function(ctx, user, next)捕获方法名称，然后只需执行以下操作即可:

First catch the method name using customer.beforeRemote('**', function(ctx, user, next) as I mentioned in question, then simply following would work:

customer.beforeRemote('*.__create__assets', function(ctx, user, next) {
      console.log(ctx.methodString, 'was invoked remotely with customers'); // customers.prototype.save was invoked remotely
      next();
    });
