如何在RestSharp中发送POST请求？

Question

I have this code which I am attempting to convert to RestSharp. I have removed the using blocks to condense it for clarity.

using System.IO;
using System.Net;
using RestSharp;

string GetResponse(string url,string data)
{
    var request = (HttpWebRequest)WebRequest.Create(url);
    request.Method = "POST";
    request.ContentType = "application/x-www-form-urlencoded";
    var bytes = Encoding.UTF8.GetBytes(data);
    request.ContentLength = bytes.Length;
    request.GetRequestStream().Write(bytes, 0, bytes.Length);
    var response = (HttpWebResponse)request.GetResponse();
    var stream = response.GetResponseStream();
    if (stream == null) return string.Empty;
    var reader = new StreamReader(stream);
    return reader.ReadToEnd();
}

I tried something to the order of:

string GetResponse(string url, string data)
{
    var client = new RestClient(url);
    var request = new RestRequest("", RestSharp.Method.POST);
    request.AddParameter("application/x-www-form-urlencoded", data);
    var response = client.Execute(request);
    return response.Content;
}

I can't seem to POST a request using RestSharp, what's the right format to send a POST request in application/x-form-urlencoded ?

Answer 1

So it turns out the parameters were all already serialized in the data string. Whereas I needed to add them to the RestSharp request manually.

foreach (var pair in data) 
{ 
    request.AddParameter(pair.Key, pair.Value); 
}

where data is a Key/Value pair struct
