Getting data for SSE from external HTTP request

[danechitoaie]

I'm trying to implement the SSE example from here https://github.com/poem-web/poem/blob/master/examples/poem/sse/src/main.rs#L30-L37

The problem is that I need to get the data from some external API that then I need to postprocess a bit and then return the chunks of data as SSE.

I've also seen a similar question here #446

Would the answer provided by @sunli829 to use mpsc::unbounded_channel(); and tokio::spawn(async move { be the solution for my use case as well? And make the needed external HTTP requests inside the tokio::spawn(async move { block?

Thanks.
