C# Fax Jobsubmit

I'm trying to create a prototype using this API to send fax messages. I'm using the samples at https://apiforums.easylink.com/content/c-sample-jobsubmit-sms-options-single-recipient as a reference.

Getting an exception with the message - The request failed with an empty response. Here is my code below

None of the services call I make seem to be working. I get the same error - The request failed with an empty response.

Here's my code for a call to Authenticate

private static void SendAuthenticate()

{

// Create service reference

var authService = new ELAuthenticate.AuthenticateService();

// Setup auth

var xDDSAuth = new ELAuthenticate.XDDSAuthType()

{

RequesterID = new ELAuthenticate.UIDType()

{

Value = "userid"

Password = "password"

};

var requestAuth = new ELAuthenticate.RequestAuthentication

{

Item = xDDSAuth

};

var request = new ELAuthenticate.Request()

{

Authentication = requestAuth,

ReceiverKey = "https://test2messaging.easylink.com/soap/sync"

};

authService.RequestValue = request;

var authRequest = new ELAuthenticate.AuthenticateRequest();

var submit_result = authService.Authenticate(authRequest);

}

Click on the URL and make sure you see the API message in your browser.

https://test2messaging.easylink.com/soap/sync

If you do, step through your code and look at both sides of EM.JobSubmit(JS_Request).

Some of the code is missing from the bottom, I do not see the ReadAndEncodedFile function, but it may just be cropped off in your paste.

Yes, I do see the API message in the browser. The thing is, this code was working a few months ago when we were first evaluating the product. Picked it up again yesterday and now it's not working. I've been digging around to see if I my have changed something accidentally.

The ReadAndEncodedFile method comes from this other forum link C# Ssample Helper Functions. This is what it looks like.

private static string ReadAndEncodedFile(string FullFileName)

{

string return_value;

return_value = ReadAndEncodedFile(FullFileName, true);

return return_value;

}

private static string ReadAndEncodedFile(string FullFileName, bool bBase64Encode)

{

// read the file

System.IO.FileStream inFile;

byte[] binaryData;

try

{

inFile = new System.IO.FileStream(FullFileName, System.IO.FileMode.Open, System.IO.FileAccess.Read);

binaryData = new byte[inFile.Length];

long bytesRead = inFile.Read(binaryData, 0, System.Convert.ToInt32(inFile.Length));

inFile.Close();

}

catch (System.Exception exp)

{

// Error creating stream or reading from it.

System.Console.WriteLine("{0}", exp.Message);

return "FAIL";

}

string base64String;

if (bBase64Encode)

{

// Convert the binary input into Base64 UUEncoded output.

try

{

base64String = System.Convert.ToBase64String(binaryData, 0);

}

catch (System.ArgumentNullException)

{

System.Console.WriteLine("Binary data array is null.");

return "FAIL";

}

// done Encoding file

}

else

{

base64String = binaryData.ToString();

}

return base64String;

}

We did change our Certificate about four months ago. Click on the URL.

https://test2messaging.easylink.com/soap/sync

In IE click the Security lock and click the View Certificate on the bottom of popup. The click the Install Certificate. Try your Submit again.

Issues Resolved

Thanks for all the help. The issue turned out to be due to the corporate proxy/firewall interfering with the requests.
