I cannot use RestSharp In my WixSharp installer, is it possible to accomplish this with HttpClient or WebClient?

Question

private async Task<AuthenticationToken> GetToken()
    {

        string username = loginDialog.username;
        string password = loginDialog.password;
        string requestString = $"Service/Login";
        RestRequest request = new RestRequest(requestString, Method.POST);
        request.AddParameter("username", username);
        request.AddParameter("password", password);
        IRestResponse<AuthenticationToken> response = await _client.ExecuteAsync<AuthenticationToken>(request);
        return response.Data;
    }

I am using RestSharp in a few projects within my solution. I can not use it within the installer, WixSharp isn't working well with RestSharp. I need to use WebClient or HttpClient to achieve the same response as I get with this Method using the RestSharp library. Is anyone able to help?

Answer 1

Sure, try this

var httpClient = new HttpClient();
var headers = httpClient.DefaultRequestHeaders;
headers.Add("Content-Tpye", "application/form-url-encoded");
string requestParams = string.Format("grant_type=password&username={0}&password={1}", username, password);
HttpContent content = new StringContent(requestParams);
var response = httpClient.PostAsync(requestString, content);
var responseContent = await response.Result.Content.ReadAsStringAsync();

            

Then you can use JSON deserializer on responseContent using NewtonSoft or any JSON library.

In the case of requirement some external assembly for Wixsharm runtime just add it like below:

var proj = ManagedProject()
proj.DefaultRefAssemblies.Add("Restsharp.dll")

And it will be avaliable for load in runtime and accessable for use.

PS Dont forget to check assembly existence in your builder executable file output location.
