HTTP Methods

HTTP, or Hypertext Transfer Protocol, is a protocol used for transferring data on the web. This protocol allows browsers and servers to establish a connection. Every time you view a page on the web, a HTTP request is sent by your browser, and in response to that, the server returns the information. This data exchange occurs through various HTTP methods, each of which has its own specific functions.

One of the most commonly used methods is GET. This method allows you to retrieve information from a server. Simply put, every time you enter a website address in your browser, this method is used. For example, when you want to view a list of articles on a blog, a GET request is sent to retrieve the article information.

The POST method is used to send data to the server. Whenever you fill out a form on a website and press send, this data is sent to the server using the POST method. This method is generally more secure than GET because the data is sent in the body of the request and is less visible to other users.

Another HTTP method, PUT, is used for updating or replacing resources on the server. Assume you want to update the information of an article in your blog; in this case, the PUT method is used to replace the old information with new data.

The DELETE method, likewise, is used to remove resources from the server. If you, as the administrator of a site, want to delete an old post, the DELETE method allows you to carry out this action.

Generally speaking, these methods are the basic requests in HTTP and knowing how to correctly implement each of them can help you design more effective and user-friendly websites.

Example Code Using an HTTP Method

        <!-- Example HTML form for sending data with POST method -->
        <form action="/submit" method="POST">
            <label for="name">Name:</label>
            <input type="text" id="name" name="name">
            <input type="submit" value="Submit">
        </form>
    

Code Explanation

<form>: This tag is used to create an HTML form.
action="/submit": This attribute specifies where the form data will be submitted (to which URL on the server).
method="POST": This attribute specifies that data will be sent using the POST method.
<label>: This tag is used to create a label for the form fields.
<input>: This tag is used to receive input from the user. type="text" is for text fields and type="submit" is for the submit button.
id="name" name="name": The properties id and name are used to identify the field and refer to it through JavaScript or when processing data on the server.
