In ASP.NET Core-6 Web API, I am consuming a third party web service as shown here:
https://thirdpartyservice.com/api/Account/GetCustomerDetail/accountNumber
accountNumber is the parameter.
I am to validate and verify if the accountNumber exists.
So I have written this code.
appsettings.json:
"MyEndpoints": {
"custAccountDetailUrl": "https://thirdpartyservice.com/api/Account/GetCustomerDetail/"
},
Kindly note that I am using HTTPClient.
Interface:
public interface IDataUtil
{;
CustomerDetail GetCustomerDetail(string accountNumber);
}
Implementation:
public class DataUtil : IDataUtil
{
private readonly IConfiguration _config;
private readonly ILogger<DataUtil> _logger;
private readonly HttpClient _myClient;
public DataUtil
(
IConfiguration config,
ILogger<DataUtil> logger,
HttpClient myClient
)
{
_config = config;
_logger = logger;
_myClient = myClient;
}
public CustomerDetail GetCustomerDetail(string accountNumber)
{
var responseResults = new CustomerDetail();
try
{
string custAccountNoUrl = _config.GetSection("MyEndpoints").GetValue<string>("custAccountDetailUrl") + accountNumber;
_myClient.DefaultRequestHeaders.Accept.Clear();
_myClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
HttpResponseMessage response = _myClient.GetAsync(custAccountNoUrl).Result;
if (response.IsSuccessStatusCode)
{
var stringResult = response.Content.ReadAsStringAsync().Result;
responseResults = JsonConvert.DeserializeObject<CustomerDetail>(stringResult);
}
}
catch (Exception ex)
{
throw new Exception($"An Error occured " + ex.ToString());
}
return responseResults;
}
}
Then I try to call it this way:
var accDetail = _dataAccess.GetCustomerDetail(model.AccountNumber);
Program.cs:
var builder = WebApplication.CreateBuilder(args);
ConfigurationManager configuration = builder.Configuration;
var environment = builder.Environment;
var swaggerDocOptions = new SwaggerDocOptions();
// Configure the HTTP request pipeline.
app.UseSwagger();
app.UseSwaggerUI();
app.UseHttpsRedirection();
app.UseAuthentication();
app.UseAuthorization();
app.UseHsts();
app.UseCors(x => x
.AllowAnyOrigin()
.AllowAnyMethod()
.AllowAnyHeader());
app.UseStaticFiles();
app.MapControllers();
string? port = Environment.GetEnvironmentVariable("PORT");
if (!string.IsNullOrWhiteSpace(port))
{
app.Urls.Add("http://*:" + port);
}
app.Run();
The surprising thing is that it works on the local, but when I deployed it to the Server using IID, I got this error:
System.Exception: An Error occured System.InvalidOperationException: An invalid request URI was provided. Either the request URI must be an absolute URI or BaseAddress must be set.

line 71:
HttpResponseMessage response = _myClient.GetAsync(custAccountNoUrl).Result;
line 80:
throw new Exception($"An Error occured " + ex.ToString());
How do I resolve this?
