Webapi mvc session cannot be obtained all the time. webapimvc

Some time ago, when I wrote an interface to a mobile client, I encountered a problem that the mailbox session cannot be obtained by calling the interface. Let me talk to the comrades who have encountered problems.

I checked a lot of information on the Internet and asked some friends. Finally, the solution is found.

 

We all know that webapi does not enable session support by default. Therefore, you need to rewrite the Global file as follows:

Public override void Init ()
{
This. PostAuthenticateRequest + = (sender, e) => HttpContext. Current. SetSessionStateBehavior (SessionStateBehavior. Required );
Base. Init ();
}

Now you can store sessions in the api controller you created,

HttpContext. Current. Session ["a"] = "1111 ";

However, when your mailbox is sent out. When you open the mailbox page for verification, you find that the obtained session is null. Here I want to explain it.

During verification, please use JavaScript asynchronous processing. Go to the controller where you set the session and write an interface method. Ajax call.

You can get the session in the corresponding controller.

 

This is my temporary solution. I don't know if there is any better way to do this. Learn from each other.
