There are a few ways to test the HTTP response.

Method 1: Using the browser's developer tools

The browser's developer tools can be used to inspect the HTTP response. To do this, open the browser's developer tools and navigate to the "Network" tab. In the "Network" tab, you will see a list of all the HTTP requests that have been made by the browser. To view the response for a specific request, click on the request in the list. The response will be displayed in the "Response" tab.

Method 2: Using a third-party tool

There are a number of third-party tools that can be used to test the HTTP response. Some popular tools include Postman, Insomnia, and SoapUI. These tools can be used to make HTTP requests and view the response.

Method 3: Using the curl command

The curl command can be used to make HTTP requests from the command line. To use curl to test the HTTP response, open a terminal window and type the following command:

curl {url}

Replace {url} with the URL of the HTTP request that you want to test. The response will be printed to the console.

Here is an example of how to use curl to test the HTTP response for the following URL:

https://jsonplaceholder.typicode.com/todos/1

The following command will make an HTTP request to the URL and print the response to the console:

curl https://jsonplaceholder.typicode.com/todos/1

The response will be a JSON object that contains the data for the todo item.
