I'm trying to improve the information provided in response to an error handled within an app.
This is the code:
Try
httpRequestObj = HttpWebRequest.Create(strRequest)
httpRequestObj.Method = "GET"
httpRequestObj.UseDefaultCredentials = True
* httpResponse = httpRequestObj.GetResponse
Using reader As StreamReader = New StreamReader(httpResponse.GetResponseStream())
strXML = reader.ReadToEnd()
End Using
Catch ex As WebException
'do something with ex
End Try
The webexception is thrown on the * line
Currently all I see in the Exception is "The remote server returned an error: (500) Internal Server Error". I've looked at the exception in debug but the info I need isn't there- I guess the response would need to be read in to see that info but it never gets that far.
If I take the request and paste it into my browser directly I can see the error details in XML format that is returned from the API I'm calling, info like:
<Error>
<description>info I want to get to here</description>
<detail />
<code>info I want to get to here</code>
<source />
<category>info I want to get to here</category>
<file>info I want to get to here</file>
<line>info I want to get to here</line>
<pad />
</Error>
Is there any way I can change this code so that I can get past the 500 error and see the actual response, I'd like to be able to parse this xml to find out the real problem for the failure.
Note: the Exception does have an ex.Response (System.Net.HttpWebResponse), but I can't see the info I need in there, only a load of Header info.
You can get the error response from the exception....
try
{
....
} catch(Exception e) {
if (e is WebException && ((WebException)e).Status==WebExceptionStatus.ProtocolError)
{
WebResponse errResp = ((WebException)e).Response;
using(Stream respStream = errResp.GetResponseStream())
{
// read the error response
}
}
}
System.Net.WebResponse response = null;
try
{
response = wreq.GetResponse();
}
catch (WebException e)
{
if (e.Status == WebExceptionStatus.ProtocolError)
{
string error = new System.IO.StreamReader(e.Response.GetResponseStream()).ReadToEnd();
}
}
catch (Exception e)
{
}
as simple as this, You will get entire response in the string error.
