How to use async-http-client

I am trying to execute the example of async-http-client doku. But unfortunately the code in the closure is not executed. Why?

import AsyncHTTPClient

let httpClient = HTTPClient(eventLoopGroupProvider: .createNew)
httpClient.get(url: "https://swift.org").whenComplete { result in
    print (result)
    switch result {
    case .failure(let error):
        print("failure")
    case .success(let response):
        if response.status == .ok {
            print("success")
        } else {
            print("error in response")
        }
    }
}

In the console I get: Program ended with exit code: 0. So it is executed with success. But there is no print statement in the console.

Thanks!

Solution

  • It is because the main thread is getting executed before the request is done so no print statement will get called unless you ask the main thread to wait for the httpclient
