HTTP request in ASP.NET

Question

I have only HTTP API for my SMS gateway for which I create an ASP.NET application to send SMS using ASP.NET page. The below string url is the HTTP API. Now, how to post this url in ASP.NET page to send SMS.

protected void Page_Load(object sender, EventArgs e)
    {
        string userk = "***********";
        string passk = "***********";
        string senderk = "someid";
        string phonek = "00000000000";
        string messagek = "This is a test API";
        string priorityk = "ndnd";
        string typek = "normal";
        string url = "http://indiansms.smsmaker.in/api/sendmsg.php?user=" + userk + "&pass=" + passk + "&sender=" + senderk + "&phone=" + phonek + "&text=" + messagek + "&priority=" + priorityk + "&stype=" + typek;
    }

@Michael - Question is changed. Please reread the question. Also I just asked here how to post not to create an API for me. Moreover I didn't receive any relevant answer to my previous question. — Mal

You're trying to solve the same problem, just phrased differently. And "I didn't get a good answer" is not a reason to repost. — Michael Petrotta

@Michael - I believe that SO users answering to this question is much easier than previous one as my previous question is incomplete. But if I edit my previous question due to timeout its getting back and nobody is looking at that question and that question will be left over as a question forever. — Mal

You can use the WebClient.UploadValues() method.

Have you tried using either WebRequest or WebClient? The fact that you're doing this from within an ASP.NET page is mostly irrelevant...

Note that you should escape URI parameters - otherwise you'll run into trouble with values such as a message of "hello & goodbye".

Thanks! this is working. but what do you mean by URI parameters?

Jon Skeet Over a year ago

@Kars: The username, message, priority etc - see Uri.EscapeUriString.

But what's the alternative? if I remove & how HTTP API differentiates values?

Jon Skeet Over a year ago

@Kars: You don't remove & - you use it as a delimiter, but escape it within values (along with other characters).

Mal Over a year ago

do you mean "&" + "pass" + passk " for "&pass=" + passk

Maybe using HttpWebRequest with preset data

        HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create("https://myurl");
        request.Method = "POST";
        HttpWebResponse response = (HttpWebResponse)request.GetResponse();
