s the difference between using the GET method versus POST? If a GET request is used, the form parameters are encoded in the URL in what is called a query string. The form parameters can be anything, and in the example we gave earlier they would be the username and password for your email provider. Here'

s an example of the query string that would be generated if we were to use a GET request: www.someemailprovider.com/?login=joe@email.com&

password=xxyz In the GET request above, you can see that the form parameters (login and password) are attached to the end of the URL itself. Note that defining a login form to use the GET request method C as we did in this example C is a very bad idea. This is because people logging in will see their passwords being displayed in the url and may be led to think that your site is not secure. One should almost always use a POST form whenever passwords are involved, for other reasons that are explained below. A POST request, unlike a GET request, passes the form parameters in the body of the HTTP request, not in the URL. This happens behind the scenes, in what can be thought of as an HTTP '

dialogue'

between your web browser and a webserver. The main thing to keep in mind as a programmer is that defining your form to use the GET method does not protect against causing changes. You could use a GET request to do pretty much the same thing as a POST query. It'

s just that browsers are generally coded to expect that POST requests will be used for things that will cause changes C like placing an order, or writing to a database, etc . GET requests should be used for Java基础知识
