parrot os postman download with code examples

Parrot OS is a popular operating system for ethical hackers, security researchers, and penetration testers. It includes a wide variety of tools for network security, encryption, and privacy protection. One of the tools available in Parrot OS is Postman, which is a versatile tool for testing APIs and building HTTP requests.

In this article, we will discuss how to download and install Postman in Parrot OS, and provide some code examples to get you started with using the tool. We will cover the following topics:

• Downloading and installing Postman in Parrot OS
• Creating a test collection
• Writing a POST request
• Writing a GET request
• Running the test collection

Downloading and Installing Postman in Parrot OS

Postman can be downloaded and installed in Parrot OS using a few simple steps. First, open up a terminal and enter the following command to download the Postman installer:

wget https://dl.pstmn.io/download/latest/linux64 -O postman.tar.gz

This will download the latest version of Postman for 64-bit Linux systems. Once the download is complete, run the following commands to extract the installer and move it to the /opt directory:

tar -xzf postman.tar.gz
sudo mv Postman /opt/

Now that Postman is installed, you can launch it using the following command:

/opt/Postman/Postman

Creating a Test Collection

Once you have Postman up and running, the next step is to create a test collection. A collection is a group of API requests that can be saved and reused later. To create a new collection, click on the "New" button in the top-left corner of the Postman window and select "Collection". Give your collection a name and click "Create".

Writing a POST Request

To demonstrate how to use Postman, we will write a simple API request. In this example, we will use the Reqres API, which provides mock data for testing.

1. Open Postman and create a new request by clicking on the "New" button in the top-left corner of the window. Select "Request" from the dropdown menu.

2. In the request window, enter the URL for the Reqres API: https://reqres.in/api/users

3. Select "POST" from the dropdown menu next to the URL field.

4. Click on the "Body" tab and select "raw". Then, in the dropdown menu to the right, select "JSON".

5. Now we can enter the request body. In this case, we will create a new user by sending a JSON object with a name and an email address. Enter the following code in the request body:

{
    "name": "John Doe",
    "email": "johndoe@example.com"
}

6. Click on the "Send" button to send the request. The response should include a JSON object with an ID and a timestamp.

Writing a GET Request

Next, we will write a GET request to retrieve the user we just created. Here are the steps to follow:

1. In Postman, create a new request by clicking on "New" and selecting "Request".

2. In the request window, enter the URL for the new user we just created: https://reqres.in/api/users/2

3. Select "GET" from the dropdown menu next to the URL field.

4. Click on the "Send" button to send the request. The response should include the JSON object for the user we just created.

Running the Test Collection

Now that we have created two API requests, we can save them as a test collection and run them together. Here are the steps to follow:

1. In Postman, click on the "Save" button in the top-right corner of the window. Give your collection a name and click "Save".

2. Click on the "Runner" button in the top-left corner of the window.

3. Select the collection you just created from the dropdown menu.

4. Click on the "Run" button.

5. Postman will now run each request in the collection and display the results in the "Tests" tab. If all tests pass, you should see a green checkmark next to each request.

Conclusion

Postman is a valuable tool for testing APIs and building HTTP requests. With its user-friendly interface and powerful features, it's a must-have tool for anyone working with web APIs. In this article, we covered how to download and install Postman in Parrot OS, and provided some code examples to get you started with using the tool. We hope this article has been helpful and informative, and we encourage you to start using Postman in your own projects.

Downloading and Installing Postman in Parrot OS

To download and install Postman in Parrot OS, it's important to note that Parrot OS is based on Debian which is why the installation process is similar to that of Debian-based systems. The first step of the process is to open up a terminal window on your Parrot OS and paste the following command:

wget https://dl.pstmn.io/download/latest/linux64 -O postman.tar.gz

This command downloads the Postman installer for Linux systems to your computer. The next step is to extract the installer using the following command:

tar -xzf postman.tar.gz

Once the extraction is complete, the installer will be on your system's Downloads folder. You can now move the files to the /opt directory on your Parrot OS using the following command:

sudo mv Postman /opt/

Finally, you can launch Postman by running the following command:

/opt/Postman/Postman

Creating a Test Collection

When using Postman, you may have multiple API requests to test. Creating a test collection is a useful way of grouping them to ensure they are all tested together. To create a test collection:

1. Click on the "New" button in the top-left corner of the Postman window.
2. Select "Collection" from the dropdown menu to create a new collection.
3. Type in a descriptive name for the collection.
4. Click on "Create" to create the collection.

Writing a POST Request

To write a POST request using Postman:

1. Open Postman and create a new request by clicking on the "New" icon in the top-left corner of the Postman window.
2. In the request window, enter the URL for the API endpoint.
3. Select "POST" from the dropdown menu next to the URL field.
4. Input the data that needs to be sent using the POST request in the "Body" tab.
5. Click on the "Send" button to send the POST request to the server.

Writing a GET Request

To write a GET request using Postman:

1. Open Postman and create a new request by clicking on the "New" icon in the top-left corner of the Postman window.
2. In the request window, enter the URL for the API endpoint.
3. Select "GET" from the dropdown menu next to the URL field.
4. If the server requires any parameters to be sent along with the GET request, input them in the "Params" tab.
5. Click on the "Send" button to send the GET request to the server.

Running the Test Collection

To run a test collection in Postman:

1. Click on the "Collections" tab in the Postman window.
2. Click on the collection you wish to run.
3. Click on the "Runner" button in the top-left corner of the Postman window.
4. Select the environment against which the collection has to be run.
5. Click on the "Run" button to start running the tests.

After running the tests, the status of each test will be displayed, such as whether the test passed or failed. You can view the details of each test by clicking on it.
