Here is what you need to do to replicate your spawn example:
# async version
import httpclient, asyncdispatch, json , times
let time = cpuTime()
proc callStrategy (i : int) {.async.} =
echo("request " & $i)
let client = newAsyncHttpClient()
client.headers = newHttpHeaders({ "Content-Type": "application/json" })
let body = %*{
"Pid":i
}
let response = await client.request("https://reqres.in/api/strategy";,
httpMethod = HttpPost,
body = $body)
echo response.status
echo await response.body
echo("done " & $i)
proc loop (num: int) {.async.} =
echo "executing call number: " , num
var futures: seq[Future[void]] = @[]
for i in 1..num:
echo "executing call number: " , i
futures.add callStrategy(i)
await all(futures)
waitFor loop(10)
echo "Time taken: ",cpuTime() - time
Run
