Service Return

Navigation
1

I have the following problem, I make an ajax call to my service and it returns me a paged list everything ok .. And I have a button where I download it to excel, only because it is a very heavy table and I can not paginate it in Excel, I just have the time out error in the return of my ajax call.

I've heard of a stop that you make the call and while the service is processed I have another service asking if it's finished and when it finishes it returns to the client but I have no idea of the name of that call or if there is any way better to accomplish this ..

Can anyone help me please?

There are several ways to implement such a mechanism, called an asynchronous process , where processing a heavy task occurs in parallel with the original request. A default flow could be described as follows:

  • The T1 task is requested by the C1 client.
  • The server initializes a thread in background where the task starts executing. It assigns an ID to this process - for example, ID1 .
  • The server returns the process ID to the client, allowing it to continue to be used by the user.
  • From time to time the client asks the server what the execution status of the ID1 task is; the return can be, for example, 'canceled', 'running' or 'terminated'.
  • If completed, the server can return the content generated by processing in background .
