I am developing an extension for Edge where I need to send more than 1MB of data to the extension from UWP.
I have chunked the data to be less than 1MB and tried to send reply multiple times something like below
private async void OnAppServiceRequestReceived(AppServiceConnection sender, AppServiceRequestReceivedEventArgs args) {
AppServiceDeferral messageDeferral = args.GetDeferral();
// This is to be replaced with enumerator
for (int i = 0; i < number_of_chunks; i++) {
// construct reply identifying the chunk number and termination
await args.Request.SendResponseAsync(reply);
}
messageDeferral.Complete();
}
The app service is cancelled when sending the second response in the above loop. It seems like a response can be sent only if there is a corresponding request. Can someone confirm this?
Are there any alternative mechanisms in UWP to send the data asynchronously without a request?
Another option I can think of is to have the chunking logic moved to the background and it doesn't feel right.
FWIW, Chrome & Firefox doesn't have such limitation and I am able to send messages to stdout asynchronously.
Update#1: Peter, I am afraid I get the same error "A method was called at an unexpected time" for the second sendReply. I tried the following and hope this is what you meant.
private async void OnAppServiceRequestReceived(AppServiceConnection sender, AppServiceRequestReceivedEventArgs args) {
// This is to be replaced with enumerator
for (int i = 0; i < number_of_chunks; i++) {
// construct reply identifying the chunk number and termination
AppServiceDeferral messageDeferral = args.GetDeferral();
await args.Request.SendResponseAsync(reply);
messageDeferral.Complete();
}
}
