how to send POST HTTP request from Google Chrome without any extensions?

Can we send POST HTTP requests in Google Chrome when using Rest Services? I have tried few extensions but I need directly from Chrome browser

Can I send a POST request from Chrome?

You cannot make a POST request by using a web browser, as web browsers only directly support GET requests. For this example, we assume that you have installed a REST client browser plugin. Chrome and Firefox both support open source Rest Client plugins that allow for the invocation of REST APIs from the browser.

How can we send a HTTP request without using browser?

Send an HTTP request by creating a URL and getting the connection for it, and casting it to HttpURLConnection. Add an "If-Modified-Since" header, with the download date of your local file. If the server responds with 304 (not modified), then your local version is up-to-date.

You can do the post and get in the same way as the browser does. You can use the header to put in information in key, value pair. Here is a tutorial on how you can do it - Send POST data using XMLHttpRequest

But it would be better if you use chrome extension POSTMAN which is very extensive and clean for testing REST services.
