Cancel HttpClient on azure function in case the operation takes longer than x minutes

Question

I have an azure function which has been called every 5minutes. The function takes less than a min to respond but sometimes took longer than normal and causes some logical issues in my app. How can I cancel the request if takes more than x min (e.g. 4min)?

var response = await client.GetStringAsync()

You have two choices:

1. Set timeout for your HttpClient

client.Timeout = TimeSpan.FromMinutes(4);

try
{
    var response = await client.GetStringAsync();
}
catch (TaskCanceledException)
{
    // your logic when timeout happens
}

2. Cancel async task

var cts = new CancellationTokenSource()
cts.CancelAfter(4 * 60 * 1000);

try
{
    var response = await client.GetStringAsync(uri, cts.Token);
}
catch (TaskCanceledException)
{
     // your logic when timeout happens
}
