Code to be written once

Question

Hi

I have below code & i don't want to write in every Program. It should be written once . How it can be done

Parameters should be passed to the calling program and respose returned by Api should be displayed

private void GetCourier(string token)
{
    try
    {
        var client = new RestClient("htts://api.nimbuspost.com/v1/courier");
        client.Timeout = -1;
        var request = new RestRequest(Method.GET);
        request.AddHeader("Content-Type", "application/json");
        request.AddHeader("Authorization", "Bearer " + token);

        request.AddParameter("origin", txtWeight.Text, ParameterType.RequestBody);
        request.AddParameter("destination", txtLength.Text, ParameterType.RequestBody);


        request.AddHeader("content-type", "application/json");
        IRestResponse response0 = client.Execute(request);

        Root root = JsonConvert.DeserializeObject<Root>(response0.Content);
        foreach (var item in root.data)
        {
            ddlCourier.Items.Add(new ListItem(item.name, item.id));
        }
    }
    catch (Exception ex)
    {
        Response.Write(ex.Message + "</br>CreateToken");
    }
}

Hi, You can create a function to re-use same code. Please check below code example. public RestResponse GetResponse(string token, string endPointUrl, Dictionary parameters) { var client = new RestClient(endPointUrl); var request = new RestRequest { Method = Method.Get, Timeout = -1 }; request.AddHeader("Content-Type", "application/json"); request.AddHeader("Authorization", "Bearer " + token); foreach (var parameter in parameters) { request.AddParameter(parameter.Key, parameter.Value, ParameterType.RequestBody); } request.AddHeader("content-type", "application/json"); return client.Execute(request); } And this function you can call like in below code var parameters = new Dictionary (); parameters.Add("origin", txtWeight.Text); parameters.Add("destination", txtLength.Text); Root root = JsonConvert.DeserializeObject (GetResponse("your-token","your-endpoint-url",parameters).Content); foreach (var item in root.data) { ddlCourier.Items.Add(new ListItem(item.name, item.id)); } Regards, Pasang

You shouldn't return/add ddlcourier from a common method, rather do this public JsonResult GetCourier(string token) { var client = new RestClient("htts://api.nimbuspost.com/v1/courier"); client.Timeout = -1; var request = new RestRequest(Method.GET); request.AddHeader("Content-Type", "application/json"); request.AddHeader("Authorization", "Bearer " + token); request.AddParameter("origin", txtWeight.Text, ParameterType.RequestBody); request.AddParameter("destination", txtLength.Text, ParameterType.RequestBody); request.AddHeader("content-type", "application/json"); IRestResponse response0 = client.Execute(request); Root root = JsonConvert.DeserializeObject (response0.Content); return Json(new {status=root.status, response=root}); }

try this private static List GetCourier(string token, string origin, string destination) { try { var client = new RestClient("htts://api.nimbuspost.com/v1/courier"); client.Timeout = -1; var request = new RestRequest(Method.GET); request.AddHeader("Content-Type", "application/json"); request.AddHeader("Authorization", "Bearer " + token); request.AddParameter("origin", origin, ParameterType.RequestBody); request.AddParameter("destination", destination, ParameterType.RequestBody); request.AddHeader("content-type", "application/json"); IRestResponse response0 = client.Execute(request); if (response0.IsSuccessful) { var dropdownLists = new List (); Root root = JsonConvert.DeserializeObject (response0.Content); foreach (var item in root.data) { var dropdownList = new DropdownList() { id = item.id, name = item.name }; dropdownLists.Add(dropdownList); } return dropdownLists; } else { Console.WriteLine(string.Format("Failed. Code : {0}", response0.StatusCode)); return new List (); } } catch (Exception ex) { Console.Write(ex.Message + " CreateToken"); return new List (); } } Dropdownlist class public class DropdownList { public string id { get; set; } public string name { get; set; } } uses var result = GetCourier("your token", txtWeight.Text, txtLength.Text); ddlCourier.DataSource = result; ddlCourier.DataBind();

make the method public and return JsonResult instead public JsonResult GetCourier(string token) { return Json(new {status=status, response=JsonConvert.Deserialize(yourObject)}); }

Hey Ramco, you have already mentioned Root class in your question. Use the same Root class.

Hi Sachin ON below line i am getting error - Using the generic type JsonResult requires 1 type arguments public JsonResult GetCourier(string token, Int32 origin, Int32 destination,string PaymentType,Int32 OrderAmount) Thanks

Typically you need to follow a few things here, such as ExternalInterface Library => ( This is the gateway to connect the external system) Here you have the option to create API Request and Response WCF Service Proxies Web Services Under the API Folder, you have to create Response and Request. The request is the one which will till this part var client = new RestClient(input parameter); client.Timeout = -1; var request = new RestRequest(Method.GET); request.AddHeader("Content-Type", "application/json"); // input parameter may be json or xml request.AddHeader("Authorization", "Bearer " + token); // input parameter request.AddParameter("origin", txtWeight.Text, ParameterType.RequestBody); // input param request.AddParameter("destination", txtLength.Text, ParameterType.RequestBody); // inmput param request.AddHeader("content-type", "application/json"); once done Get the Response public GetResponse(request){ IRestResponse response0 = client.Execute(request); Format Required format response } one more function to format as per the required format response Finally call this library and method from source , you can reuse this anywhere even for calling other api / wcf/ web service

Hi Sorry Sachin. I want for this below part . Parameters (Origin & Destination) should be passed & then Json result should be returned try { var client = new RestClient("htts://api.nimbuspost.com/v1/courier"); client.Timeout = -1; var request = new RestRequest(Method.GET); request.AddHeader("Content-Type", "application/json"); request.AddHeader("Authorization", "Bearer " + token); request.AddParameter("origin", txtWeight.Text, ParameterType.RequestBody); request.AddParameter("destination", txtLength.Text, ParameterType.RequestBody); request.AddHeader("content-type", "application/json"); IRestResponse response0 = client.Execute(request); Root root = JsonConvert.DeserializeObject (response0.Content); foreach (var item in root.data) { ddlCourier.Items.Add(new ListItem(item.name, item.id)); } } Thanks
