Form & method [POST ~ GET ],

In <form.../>, the method attribute specifies the method in which the form submits the request. There are two methods: GET request and POST request. The default method is GET request. The difference between the two methods: get requests are sent by entering the access address in the address bar of the browser, that is, they are transmitted through the address bar. You can see the request parameter name and value in the address bar. The get parameter has a length limit, and the transmitted data volume is small, generally not greater than 2 kb. POST requests are usually sent by submitting forms. It transfers a large amount of data, which is generally considered unlimited. The request parameters sent in POST mode and their corresponding values are transmitted in the html header. You cannot see the Request Parameters in the address bar. Relatively speaking, the POST request method is more secure than the GET request method. On an HTML page, you can submit a request in either of the following ways: submit a form or use a hyperlink. The submission form allows you to enter Request Parameters and submit the request in POST mode. Only GET requests can be submitted in hyperlink mode. hyperlink submission requests can also contain request parameters, but cannot collect user input.
