Question

在我的应用程序Application_Start()事件期间，我想触发对地址的HTTP请求。我绝对不希望Application_Start()和App Start的任何费用以任何方式延迟。我不关心请求的回复。

以完全无阻塞的方式触发此请求的最正确方法是什么？

Answer 1

我会做这样的事情：

Task.Run(() =>
{
        using (var httpClient = new HttpClient())
        {
            httpClient.BaseAddress = new Uri("https://something.com/");
            var content = new StringContent("content");
            var result = httpClient.PostAsync("path/to/Service" , content);
            result.Wait();
        }
});

Answer 2

我建议只是异步触发请求

using(var client = new HttpClient())
{
    client.PostAsJsonAsync("{url}",content)
}

例如，

将触发请求并继续

Answer 3

您可以为此目的使用WebClient.UploadStringAsync方法

此方法不会阻止调用线程。

它可以抛出

ArgumentNullException
WebException

以这种方式使用

    var client = new WebClient();
    //remove comment from next line to execute some code after UploadString complete
    //client.UploadStringCompleted += new UploadStringCompletedEventHandler(function name to execute when finish);
    var data = "data to send";
    client.Headers.Add("Content-Type", "content type here");         
    client.UploadStringAsync(new Uri("http://www.yourDomain.com"), data);
