Sending HTTP POST request from SQL Server 2012 or SQL CLR C#

Question

Is there a generally accepted standard way for sending HTTP requests from SQL Server 2012?

What I am trying to do is to use a remote server to process a search query

Answer 1

Like Joe suggested using HttpWebRequest instead of HttpClient works without having to use unsupported assemblies:

[Microsoft.SqlServer.Server.SqlProcedure]
public static void SendRequest (string query, string table)
{
    string address = "http://localhost:9000/api/search";
    HttpWebRequest request = (HttpWebRequest) WebRequest.Create(address);
    request.ContentType = "application/json; charset=utf-8";
    request.Method = "POST";

    using (var streamWriter = new StreamWriter(request.GetRequestStream()))
    {
        string json = "{\"Query\":\""+query+"\",\"Table\":\""+table+"\"}";

        streamWriter.Write(json);
        streamWriter.Flush();
    }

    var httpResponse = (HttpWebResponse)request.GetResponse();
    using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
    {
        var result = streamReader.ReadToEnd();
    }
}
