一个呼叫主体，ASP.NET MVC + angular 6中有多个响应 [英] One call main, multiple responses in ASP.NET MVC + angular 6

问题描述

首先，我不知道这是否可行！我正在努力寻找答案.我想我不知道要搜索什么！

First of all, I have no idea if this is possible! and I'm struggling to find an answer. I think I don't know what to search for!

我有一个返回IEnumerable的端点，我想划分响应以便使用

I have an endpoint that returns IEnumerable, I want to divide the response so I used

.Skip().Take()

现在，当我拿到第一张照片时，如何在不调用相同端点的情况下拿到第二张照片！

Now when I get the first take, how can I get the second one without invoking the same endpoint!

问题是IEnumerable从不可能进行除法的另一个服务获取数据，因此我必须一次获取所有内容，然后必须调用另一个"SLOW"端点，该端点同时给我5个结果使用我从IEnumerable获得的内容.

The problem is IEnumerable gets the data from another service where it is not possible to divide, so I have to get everything at once and then I have to call another "SLOW" endpoint that gives me 5 results at the time using what I got from the IEnumerable.

所以我要做的是，划分第一个列表，进行第二个调用，将结果放在一起，返回结果并重复直到列表完成.

So what I want to do is, divide the first list, do the second call, put the result together, return this and repeat until the list is completed.

有没有一种方法可以让用户保持倾听的态度，并在到达时追加它们?

Is there a way to keep angular listening for responses and append them as they arrive?

或者我可以在得到结果后又打另一个电话，但又不需要再次请求完整列表吗? 将它保存在某个地方！".

Or can I make another call after I get the result but without requesting the complete list again ? "save it somewhere!".

推荐答案

对我要实现的目标的简单答案是不可能！.更改必须在更深层次上进行(查询数据库).

The simple answer to what I was trying to achieve is NO it is not possible. The change has to be done on a deeper level (querying the DB).

使用静态方法，但是这是一个Web应用程序，因此会出现问题，因此再次出现问题.

Using static works but then this is a web application so that would be problematic so again its a NO.

我最终得到了整个列表，然后一个一个地循环遍历，以获得慢速数据，然后将其显示给用户.

I ended up getting the whole list, then looping through it one by one to get the slow data then show it to the user.
