Hello all,
I am currently implementing token retrieval using HttpClient in the .NET Framework and have encountered an issue. I am using the SendAsync method to send the username and password in the JSON body as part of the request, but I'm experiencing difficulties with the token acquisition.
Below is a snippet of the code I am using for this operation:
public PXAction<INRegister> PrenderAntena;
[PXButton]
[PXUIField(DisplayName = "Prender Antena", MapEnableRights = PXCacheRights.Select, MapViewRights = PXCacheRights.Select, Enabled = true)]
protected virtual IEnumerable prenderAntena(PXAdapter adapter)
{
Prueba();
return adapter.Get();
}
public async Task Prueba()
{
// Use specific classes to define the JSON structure
var credentials = new Credentials
{
usuario = new FieldValue { value = "MyUser" },
contraseña = new FieldValue { value = "MyPassword" }
};
string jsonPayload = JsonConvert.SerializeObject(credentials, Formatting.Indented);
string url = "MyUrl";
var handler = new WinHttpHandler();
using (HttpClient client = new HttpClient(handler))
{
try
{
var requestMessage = new HttpRequestMessage(HttpMethod.Get, url);
requestMessage.Content = new StringContent(jsonPayload, Encoding.UTF8, "application/json");
// Use await correctly within an async method
HttpResponseMessage response = await client.SendAsync(requestMessage);
PXTrace.WriteInformation("Estado de la respuesta: " + response.StatusCode.ToString());
if (response.IsSuccessStatusCode)
{
string responseContent = await response.Content.ReadAsStringAsync();
PXTrace.WriteInformation("Respuesta del servidor: " + responseContent.ToString());
var apiResponse = JsonConvert.DeserializeObject<ApiResponse>(responseContent);
PXTrace.WriteInformation("API key: " + apiResponse.apiKey?.value.ToString());
}
else
{
string errorResponse = await response.Content.ReadAsStringAsync();
PXTrace.WriteInformation("Error en la solicitud: " + response.ReasonPhrase.ToString(), "Contenido: " + errorResponse);
}
}
catch (HttpRequestException httpEx)
{
PXTrace.WriteInformation("Excepción en la solicitud HTTP : " + httpEx.Message);
}
catch (Exception ex)
{
PXTrace.WriteInformation("Excepción en la solicitud : " + ex.Message);
}
}
}
// Class to deserialize the response
public class ApiResponse
{
public ApiKey apiKey { get; set; }
}
public class ApiKey
{
public string value { get; set; }
}
// Definition of classes for JSON structure
public class Credentials
{
public FieldValue usuario { get; set; }
public FieldValue contraseña { get; set; }
}
public class FieldValue
{
public string value { get; set; }
}However, I am receiving an error at the following line of code:
HttpResponseMessage response = await client.SendAsync(requestMessage);
To troubleshoot, I created a standalone C# .NET Framework project in Visual Studio with the same code, and it works perfectly. However, I am unable to determine what is missing or causing the issue when running it within Acumatica.
Could you please assist in identifying any potential issues or suggest improvements for successfully obtaining the token?
Thanks!
Regards!
