Send and receive a post variable

Question

I'm trying to send a post variable to the url which I'm redirecting to.

I'm currently using the Get method and sending it like this:

// Redirect to page with url parameter (GET)
Response.Redirect("web pages/livestream.aspx?address="+ ((Hardwarerecorders.Device)devices[arrayIndex]).streamAddress);

And retrieving it like this:

// Get the url parameter here
string address = Request.QueryString["address"];

How do I convert my code to use the POST method?

B.T.W., I don't want to use a form to send the post variable.

Using HttpClient:

To send POST query:

using System.Net.Http;

public string sendPostRequest(string URI, dynamic content)
    {
        var client = new HttpClient();
        client.BaseAddress = new Uri("http://yourBaseAddress");

        var valuesAsJson = JsonConvert.SerializeObject(content);
        HttpContent contentPost = new StringContent(valuesAsJson, Encoding.UTF8, "application/json");

        var result = client.PostAsync(URI, contentPost).Result;
        return result.Content.ReadAsStringAsync().Result;
    }

Where 'client.PostAsync(URI, contentPost)' is where the content is being sent to the other website.

On the other website, an API Controller needs to be established to receive the result, something like this:

[HttpPost]
    [Route("yourURI")]
    public void receivePost([FromBody]dynamic myObject)
    {
        //..
    }

However, you might also want to look into using a 307 re-direct, especially if this is a temporary solution.

Answer 2

using System.Net.Http;

POST

using (var client = new HttpClient())
{
    var values = new Dictionary<string, string>
    {
       { "thing1", "hello" },
       { "thing2", "world" }
    };

    var content = new FormUrlEncodedContent(values);

    var response = await client.PostAsync("http://www.example.com/recepticle.aspx", content);

    var responseString = await response.Content.ReadAsStringAsync();
}

GET

using (var client = new HttpClient())
{
    var responseString = client.GetStringAsync("http://www.example.com/recepticle.aspx");
}

My Personal Choice is Restsharp it's fast but for basic operations you can use this
