在websocket中，如何防止缓慢的异步响应数据不正确的修改

Question

I'm using websocket and I need to send request.

In my case, I send the first request and then I send a second request before I get the response for the first request. The response for second request came back very quickly and then the response for the first request came. At this moment, data from the later response modify the data incorrectly.

Is there any good ways to prevent this?

Answer 1

Sounds like what you really want is to queue requests.

Simplest way is to simply fire the 2nd one after the 1st one returns.

A slightly more efficient mechanism is to fire both at the same time but keep track of which is which (this should be trivial).

Even better, if you can, is to create a route that returns both bits of data you require.

You mention something about the data being wrong somehow, this is unrelated to firing off multiple requests but maybe that is the real problem here?
