RestSharp post request - Corps avec les valeurs x-www-form-urlencoded

J'utilise postman et je fais une demande api post où j'ajoute body avec x-www-form-urlencoded key/values ​​et cela fonctionne très bien chez postman.

Le problème se pose lorsque je l'essaie à partir de c # à l'aide du package RestSharp.

J'ai essayé le code suivant ci-dessous mais je n'ai pas eu la réponse. J'ai l'erreur "BadRequest" invalid_client.

public class ClientConfig {
    public string client_id { get; set; } = "value here";
    public string grant_type { get; set; } = "value here";
    public string client_secret { get; set; } = "value here";
    public string scope { get; set; } = "value here";
    public string response_type { get; set; } = "value here";
}

public void GetResponse() {
        var client = new RestClient("api-url-here");
        var req = new RestRequest("endpoint-here",Method.POST);
        var config = new ClientConfig();//values to pass in request

        req.AddHeader("Content-Type","application/x-www-form-urlencoded");
        req.AddParameter("application/x-www-form-urlencoded",config,ParameterType.RequestBody);

        var res = client.Execute(req);
        return;
    }

//Also tried this

    req.AddParameter("client_id",config.client_id,"application/x-www-form-urlencoded",ParameterType.RequestBody);
                req.AddParameter("grant_type",config.grant_type,"application/x-www-form-urlencoded",ParameterType.RequestBody);
                req.AddParameter("client_secret",config.client_secret,"application/x-www-form-urlencoded",ParameterType.RequestBody);
                req.AddParameter("scope",config.scope,ParameterType.RequestBody);
                req.AddParameter("response_type",config.response_type,"application/x-www-form-urlencoded",ParameterType.RequestBody);

//tried this too
var client = new RestClient("url-here");
            var req = new RestRequest("endpointhere",Method.POST);
            var config = new ClientConfig();
req.AddBody(config);
var res = client.Execute(req);

cela fonctionnait pour moi, c’était un générateur de facteur

        var token = new TokenValidation()
        {
               app_id = CloudConfigurationManager.GetSetting("appId"),
               secret = CloudConfigurationManager.GetSetting("secret"),
               grant_type = CloudConfigurationManager.GetSetting("grant_type"),
               Username = CloudConfigurationManager.GetSetting("Username"),
               Password = CloudConfigurationManager.GetSetting("Password"),
        };

        var client = new RestClient($"{xxx}{tokenEndPoint}");
        var request = new RestRequest(Method.POST);
        request.AddHeader("content-type", "application/x-www-form-urlencoded");
        request.AddParameter("application/x-www-form-urlencoded", $"app_id={token.app_id}&secret={token.secret}&grant_type={token.grant_type}&Username={token.Username}&Password={token.Password}", ParameterType.RequestBody);
        IRestResponse response = client.Execute(request);

        if (response.StatusCode != HttpStatusCode.OK)
        {
            Console.WriteLine("Access Token cannot obtain, process terminate");
            return null;
        }

        var tokenResponse = JsonConvert.DeserializeObject<TokenValidationResponse>(response.Content);

Personnellement, je trouve cette méthode plus efficace pour l’envoi de données Form-UrlEncoded.

public void GetResponse() {
        var client = new RestClient("api-url-here");
        var req = new RestRequest("endpoint-here",Method.POST);
        var config = new ClientConfig();//values to pass in request

        // Content type is not required when adding parameters this way
        // This will also automatically UrlEncode the values
        req.AddParameter("client_id",config.client_id, ParameterType.GetOrPost);
        req.AddParameter("grant_type",config.grant_type, ParameterType.GetOrPost);
        req.AddParameter("client_secret",config.client_secret, ParameterType.GetOrPost);
        req.AddParameter("scope",config.scope, ParameterType.GetOrPost);
        req.AddParameter("response_type",config.response_type, ParameterType.GetOrPost);

        var res = client.Execute(req);
        return;
}
