An HTTP request from a C # program that does not require a response

Question

I did some socket work where I had to send a request because I need an answer, but I need to write something in C # that is just going to call an old web page that needs to be answered for 10 seconds, and don't wait for an answer ( errors will be marked by DB calls).

Is there an easy way to do this?

Answer 1

Try this topic: Async HttpWebRequest without waiting from a web application

(This approach is sometimes called "fire and forget")

Answer 2

You can use Async methods in the System.Net.WebClient class:

var webClient = new System.Net.WebClient(); webClient.DownloadStringAsync("your_url") 

Answer 3

Try this MSDN document

Answer 4

You mean something like:

 HttpWebRequest req = (HttpWebRequest) WebRequest.Create(url); HttpWebResponse resp = (HttpWebResponse) req.GetResponse(); resp.Close(); 

Answer 5

Use the Webrequest class, but run the request asynchronously . In fact, this request is executed in another thread, which you can also do yourself.

Answer 6

If you want to add parameters via POST, you can also use this (and just ignore the answer if you don't need one). It takes parameters in the form of a dictionary, but can be easily changed to work in any way.

 private String DownloadData(String URL, Dictionary<String, String> Parameters) { String postString = String.Empty; foreach (KeyValuePair<string, string> postValue in Parameters) { foreach (char c in postValue.Value) { postString += String.Format("{0}={1}&", postValue.Key, postValue.Value); } } postString = postString.TrimEnd('&'); HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(URL); webRequest.Method = "POST"; webRequest.ContentLength = postString.Length; webRequest.ContentType = "application/x-www-form-urlencoded"; StreamWriter streamWriter = null; streamWriter = new StreamWriter(webRequest.GetRequestStream()); streamWriter.Write(postString); streamWriter.Close(); String postResponse; HttpWebResponse webResponse = (HttpWebResponse)webRequest.GetResponse(); using (StreamReader responseStream = new StreamReader(webResponse.GetResponseStream())) { postResponse = responseStream.ReadToEnd(); responseStream.Close(); } return postResponse; }
