JMeter - Regular Expression Extractor - CSRF Token Login - Django and Laravel Login with JMeter

CSRF Token is a common practice to prevent the Cross Site Request Forgery Attacks. If you are testing such web applications where a CSRF token is sent with the http request, you might find difficult to achieve the results with JMeter.

Most common hurdle is the Login Page because this is the place where you find CSRF token parameter with username and password. Actually CSRF Token should be used with every request where data is getting inserted in the database but generally developers do not use in the other web forms.

So How to Log into the application which has CSRF token implemented in the login page.

Here is the complete guide to handle the CSRF Tokens in the JMeter.

Docker - Attach port to a running container | Map a port of host with the container

When you run a container, you attach port with the run command as docker does not provide any option to attach a port for a running container.

Generally you use parameter '-p' with run command to map the host port with the container

docker run -it -p 80:80 -p 3306:3306 -v /var/www/html:/var/www/html ubuntu:18.04 /bin/bash

If you want to attach a port or multiple ports to a running container, here is the solution.

1. Stop the container and cd into the container directory

cd /var/lib/docker/containers/d260db74672bf96c07536835229b1b3609c74f24ba54e4c4d0e314b24d01ae19

(long string is container id)

2. Edit files configv2.json and hostconfig.json

3. Add your extra require port settings in these two files
hostconfig.json

"PortBindings":{"21/tcp":[{"HostIp":"","HostPort":"21"}],"27017/tcp":[{"HostIp":"","HostPort":"27017"}],"3306/tcp":[{"HostIp":"","HostPort":"3306"}],"80/tcp":[{"HostIp":"","HostPort":"80"}]},

configv2.json

"ExposedPorts":{"21/tcp":{},"27017/tcp":{},"3306/tcp":{},"80/tcp":{}},

Here we have attached four host ports with the container.

4. Restart Docker, start container and log into it. You should be able to access the service of container in the host using attached port.

Using this method you can connect single port or multiple ports.

Note : You can map one port of host with the other of container. Example you can map port 89 of host with port 80 of docker container. This way you can access web server (apache / nginx ) service of container on port 89 of host.

You can see practical example in this video to understand the steps better.
