User448619955 posted

hey there.

I want to use web api in my app, when iI run my application I get an Internal Error message.

using (var client = new HttpClient())
            {
                client.BaseAddress = new Uri("http://x.x.x.x:90");
                client.DefaultRequestHeaders.Accept.Clear();
                client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

                //GET Method
                HttpResponseMessage response = await client.GetAsync("/api/Get_Customer?username=edf&password=erw&idno=12345");

//status code 500,response gets an internal server error message

Hi,

http 500 is a server side error. Try maybe to inspect the payload to look for a hint else you'll have to guess (a wrong idno maybe or to get in touch with the 3rd party - or if you look at the other app, by default it should go to the Windows log).

Hi vahid.ch,

If possible, you can try to access this API endpoint from browser, and check if you can find more/detailed error message, which would help troubleshoot the issue.

And you can also try to check if there are any useful information in response content, like below.

using (var client = new HttpClient())
{
    client.BaseAddress = new Uri("http://x.x.x.x:90");

    //code logic

    //GET Method
    HttpResponseMessage response = await client.GetAsync("/api/Get_Customer?username=edf&password=erw&idno=12345");
    Stream stream = await response.Content.ReadAsStreamAsync();
    StreamReader reader = new StreamReader(stream);
    string rc = reader.ReadToEnd();
}

Besides, you can check logging file to get error logs if you can access the hosting server.
