Both GET and POST are utilized to transmit data from client to server in HTTP protocol but the major distinction between POST and GET format is that GET maintains the request parameter attached to the URL string while POST holds the request parameter in the note body which makes it a safer method of moving data from client to server. Let’s take a look at it in more detail.
What is HTTP GET?
The Hypertext Transfer Protocol(HTTP) Get process is primarily employed at the Browser part to transmit a request to a selected server to get specific data or information. Utilizing this approach, the server should only allow us to obtain the data and not alter its condition. Therefore, it is only utilized to see something and not to alter it. Get procedure is one of the most habituated HTTP methods. The request variable of the get process is attached to the URL. Get submission is more suitable for the data which does not require to be protected (It signifies the data which does not include images or word files).
In the given HTML code we have developed a form with text field as Username and City. we have also enclosed a PHP file getmethod.php where our data would be transferred after we click the submit button.
<!DOCTYPE html> <html> <body> <form action="getmethod.php" method="GET"> Employeename: <input type="text" name="employeename" /> <br> Job: <input type="text" name="job" /> <br> <input type="submit" /> </form> </body> </html>
In the given PHP code utilizing the GET method, we have shown the Employee name and job.
<!DOCTYPE html> <html> <body> Welcome <?php echo $_GET["employeename"]; ?> </br> Your Job is: <?php echo $_GET["job"]; ?> </body> </html>
What is HTTP POST?
The Hypertext Transfer Protocol(HTTP) Post process is primarily utilized at the browser part to transmit data to a particular server to complete or reconfigure a certain resource/information. This data transmitted to the server is kept in the request part of the HTTP request. Post process ultimately guides the design of new data or reworking of a current one. Due to this active benefit, it is one of the most habituated HTTP techniques. It is not one of the safest methods because the data that is been transmitted is incorporated in the structure of the request and not in the URL. The post method is more useful for the data which ought to be safe (It indicates the data which includes photos or word files).
In the given HTML code we have developed a form with text field as Student name and Subject. we have also enclosed a PHP file postmethod.php, where our data would be dispatched once we click the submit button.
<!DOCTYPE html> <html> <body> <form action="postmethod.php" method="post"> Studentname: <input type="text" name="studentname" /> <br> Subject: <input type="text" name="subject" /> <br> <input type="submit" /> </form> </body> </html>
Now, in the following PHP code employing the POST technique, we have shown the Student’s name and subject.
<!DOCTYPE html> <html> <body> Welcome <?php echo $_POST["studentname"]; ?> </br> Student's subject is: <?php echo $_POST["subject"]; ?> </body> </html>
How Data is Encrypted in Both Methods?
It is important to note that with HTTPS, the whole HTTP request departs via the encrypted SSL line, so both GET and POST variables or methods, the URL route, cookies, and all other aspects of the request are covered against MitM meddling in transit. This can’t ensure that the server and client are safe, but it suggests that you don’t have to rely upon every spontaneous machine between the two. The hostname and port digit are detectable by a MitM, but they cannot be meddled with, besides by destroying the connection.
Traffic timings are perceptible, and this data could be utilized by an enthusiast spectator to guess what is being shared. E.g., a large file might be a video, or a typical file size fits a typical file. Systems do not implicitly fall back to HTTP if HTTPS dies; that would be disastrous. Without SSL, nothing whatsoever is covered against complete recording and/or transformation.
In the GET method, we cannot transmit a big amount of data rather restricted data is transmitted because the request variable is attached to the URL. In the POST method, a big amount of data can be transmitted because the request variable is attached to the structure.
GET request is actually sounder than Post so it is utilized more than the Post method. The POST request is not better than Get so it is utilized less than the Get method. In the case of security, the GET request is less safe because the data is disclosed in the URL bar. On the other hand, in the POST method data is safer because the data is not disclosed in the URL bar.
