Https Request

JonasPTFL

Hello everyone,
I want to do a easy Https request.
I've searched a long time in the internet and found code like this:
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
But this code isnt working...
I have crated an easy http request, which works very good:

            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(address);

            using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
            {
                var encoding = Encoding.GetEncoding(response.CharacterSet);

                using (Stream responseStream = response.GetResponseStream())
                using (StreamReader reader = new StreamReader(responseStream, encoding))
                    return reader.ReadToEnd();
             }

But i need an Https Request. So how can I do that?
Thank you!

i m sorry but not really time to explain here is it a sample who works and there are a lot of sample on google
your goal is to get a json data ?
`
const string URL_PIZZA = "http://www.pizzaboy.de/app/pizzaboy.json";

async Task GetAllPizzasDatas()
{
var httpClient = HttpClientApi.GetHttpClient();
var response = await httpClient.GetAsync(URL_PIZZA);

        if (response.IsSuccessStatusCode)
        {
            var content = await response.Content.ReadAsStringAsync();
            return content;
        }

        return null;
    }

public class HttpClientApi
{
public static HttpClient GetHttpClient()
{
//
var httpClient = new HttpClient();

        //
        httpClient.DefaultRequestHeaders.Accept.Clear();
        httpClient.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));

        return httpClient;
    }
}

`

copy paste the code, and on click on button call yourclass.GetAllPizzasData()

Hello @JonasPTFL thanks for having validate the answer don't forget to add a try catch

JonasPTFL

No problem.
I have tryed the code in my App but there is a misstake in return content; or return null;

Because "MainActivity.GetAllPizzasDatas ()" is an Async method that returns "Task", no object expression may follow a return keyword.
