JMeter Basic Authentication

I am trying to imply the basic authentication process for a web service using JMeter. But everytime it throws out an error 401:Unauthorized. I tried using the HTTP Header manager to add a header Authorization and value to it. Still it does not work. I have also tried using the HTTP Authorization manager. Still no luck. Can someone help.

Solution 1:

I've found through debugging requests coming in from JMeter that the HTTP Authorization Manager module doesn't encode the username and password correctly. It puts a newline character after the username.

To run a JMeter test against a Basic Auth protected endpoint, include the HTTP Header Manager and add the Basic Auth header yourself:

Manually Encoding Credentials

From MacOS or Linux:

echo -n "username:password" | base64
From Windows:

Go here and encode your "username:password" string

Adding the Authorization Header

In the HTTP Header Manager, add an entry with the name "Authorization" and the value "Basic [encoded credentials from above]"

Solution 2:

Basically to bypass a Basic Authorization you need to add the Authorization header with the value Basic base64(username:password). The problem is that JMeter has no base64 function embedded.

The solution is :

Step1 Add BeanShell PreProcessor (PreProcessor --> BeanShell Preprocessor)

Step2 Add the following script to the PreProcessor

import org.apache.commons.codec.binary.Base64;
byte[] encodedUsernamePassword = Base64.encodeBase64("neo4j:1234".getBytes());
vars.put("base64HeaderValue",new String(encodedUsernamePassword));
