Retrieve Response Header data by making an unauthorized HTTP GET request

[deepsie]

Hi All,

I have a requirement in which I have to make an unauthorized (401 Unauthorized) HTTP GET request without any parameters in order to retrieve the value of nonce in www-aunthenticate response header. I am using Talend Open Studio Version 6.2.1. I am new to this tool. Hence, I do not know how I can achieve the above.

I have tried tRestClient, but it threw the 401 Unauthorized error. I tried tRest component, but it has no built-in Header variable unlike tRestClient. I think both components expect either query parameters or headers. I require the response headers by using only the URL without passing any parameters/headers.

I need your help in finding a solution.

Thank you.

Have you tried using this globalMap value.....

((java.util.Map<String,java.util.List<String>>)globalMap.get("tRESTClient_1_HEADERS"))

You will require some basic Java in order to iterate over the values, but this is where you would get your headers.

Yes. I have tried that. Like I mentioned, I get the 401 unauthorized error. 

I wrote a java code to make the unauthorized request and get the required header value.

Thank you.
