Asynchronous Call

Make an asynchronous call

Alibaba Cloud Go SDK supports asynchronous calls in two ways：

  1. Using channel as return values

    responseChannel, errChannel := client.FooWithChan(request)

// this will block
response := <-responseChannel
err = <-errChannel

  2. Use callback to control the callback

    blocker := client.FooWithCallback(request, func(response *FooResponse, err error) {
    // handle the response and err
})

// blocker which is type of (chan int)，is used to control synchronization，when returning 1 means success，and returning 0 means failure.
// When <-blocker returns failure，err also will be handled by afferent callback.
result := <-blocker
