Jmeter with basic authentication

Question

I want to run a loadtest on a RestAPI which I can access via below java

        name = "username";
        String password = "password";
        String authString = name + ":" + password;
        byte[] authEncBytes = Base64.getEncoder().encode(authString.getBytes()); //
        String authStringEnc = new String(authEncBytes);
        URL url = new URL(urlStr);
        URLConnection urlConnection = url.openConnection();
        urlConnection.setRequestProperty("Authorization", "Basic " + authStringEnc);

But in jmeter I am not able add this, new to jmeter please help.

Answer 1

Since JMeter 3.2, Basic Auth is provided Out Of The Box using HttpClient4 implementation and configured by default, see:

• https://bz.apache.org/bugzilla/show_bug.cgi?id=57242
• http://jmeter.apache.org/changes.html

HTTP HC4 Implementation now provides preemptive Basic Auth enabled by default

Just add HTTP_Authorization_Manager and fill in required information.

Example:

• For this request to "http://localhost:8081" :

• Configuration will be:

This configuration will match any request starting with "http://localhost:8081"

Although my answer is downvoted for I don't know which reason, it is the best way to setup Basic Auth. Scripting is no more required at all since 3.2.
