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.

You can use the same code to generate the encoded credentials:

Add HTTP Header Manager as a child of the relevant HTTP Request sampler
Add JSR223 PreProcessor as a child of the relevant HTTP Request sampler

Put the following code into "Script" area

name = "username";
String password = "password";
String authString = name + ":" + password;
byte[] authEncBytes = Base64.getEncoder().encode(authString.getBytes()); //
String authStringEnc = new String(authEncBytes);
sampler.getHeaderManager().add(new org.apache.jmeter.protocol.http.control.Header("Authorization", "Basic " + authStringEnc));

Check Cache compiled script if available box

JMeter should now add the necessary "Authorization" header to your request.

Why was this voted down? Worked for me when the official JMeter auth manager didn't. Add "vars.get("appPassword");" if you don't want to hardcode passwords. — Shorn, May 07 '18 at 05:33

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

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"
