Unreal Engine 4.x Scripting with C++ Cookbook - Second Edition

How to do it...

1. Link to the HTTP API in your ProjectName.Build.cs file.
2. Construct an IHttpRequest object using the following code:

TSharedRef<IHttpRequest> http =  HttpModule::Get().CreateRequest();

3. Provide a callback function to call when the request progresses, which updates our user:

http->OnRequestProgress().BindLambda(    [this](FHttpRequestPtr request, int32 sentBytes, int32    receivedBytes)    -> void    {        int32 contentLen =        request->GetResponse()->GetContentLength();        float percentComplete = 100.f * receivedBytes /        contentLen;        UE_LOG(LogTemp, Warning, TEXT("Progress sent=%d bytes /        received=%d/%d bytes [%.0f%%]"), sentBytes, receivedBytes,        contentLen, percentComplete);    });

4. Process your request with http->ProcessRequest().
