I've created a custom DNN module that uses HTTPClient to send information to an external API. My HttpClient method is as follows:
public static async Task<string> CreatePayerResponse()
{
var credentials = GetCredentials();
var objEventLog = new EventLogController();
var gatewaySettings = new GatewaySetting_ProPay();
SignupResult_ProPay result = new SignupResult_ProPay();
using (HttpClient client = new HttpClient(new LoggingHandler(new HttpClientHandler())))
{
HttpRequestMessage request = new HttpRequestMessage();
HttpResponseMessage response = new HttpResponseMessage();
response.EnsureSuccessStatusCode();
client.BaseAddress = new Uri("https://xmltestapi.propay.com/ProPayAPI/signup");
client.DefaultRequestHeaders.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
string responseBody;
GatewaySetting_ProPay gatewaySetting = new GatewaySetting_ProPay();
SignupRequest payerRequest = new SignupRequest();
HttpContent content = new StringContent(payerRequest.ToString());
try
{
request.Headers.Add("Authorization", credentials);
request.Headers.Add("accept", "application/json");
response = await client.PutAsync("https://xmltestapi.propay.com/ProPayAPI/signup", content);
responseBody = await response.Content.ReadAsStringAsync();
objEventLog.AddLog("Merchant Onboarding Request Sent", portalSettings, userId,
response.ToString(), EventLogController.EventLogType.ADMIN_ALERT);
Console.WriteLine(responseBody);
}
catch (HttpRequestException ex)
{
result.Succeeded = false;
result.Status = ex.Message;
objEventLog.AddLog("Merchant Onboarding Error!", portalSettings, userId, response.ToString(),
EventLogController.EventLogType.ADMIN_ALERT);
Console.WriteLine("\nException Caught!");
Console.WriteLine("Message :{0} ", ex.Message);
}
return response.Content.ToString();
}
}
public static string GetCredentials()
{
GatewaySetting_ProPay gatewaySettings = new GatewaySetting_ProPay();
var billerAccountId = "mycreds";
var authToken = "mycreds";
var encodedCredentials =
Convert.ToBase64String(Encoding.Default.GetBytes(billerAccountId + ":" + authToken));
var credentials = string.Format("Basic {0}", encodedCredentials);
return credentials;
}
When I wire this method up to a click event, an HTTP 302 response is received and nothing is sent to the API. What modifications are needed to ensure proper transmission?
Update I still receive the following response:
Error code 302 was received from server response.
This is despite implementing the AllowAutoRedirect property and setting it to true. Here's the LoggingHandler class I've written:
public LoggingHandler(HttpMessageHandler innerHandler) : base(innerHandler)
{
}
protected async Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken, HttpClientHandler handler)
{
Console.WriteLine("Request:");
Console.WriteLine(request.ToString());
if (request.Content != null)
{
Console.WriteLine(await request.Content.ReadAsStringAsync());
}
Console.WriteLine();
handler.AllowAutoRedirect = true;
HttpResponseMessage response = await base.SendAsync(request, cancellationToken);
Console.WriteLine("Response:");
Console.WriteLine(response.ToString());
if (response.Content != null)
{
Console.WriteLine(await response.Content.ReadAsStringAsync());
}
Console.WriteLine();
return response;
}
Is this the proper way to implement HttpClientHandler and associated properties?
