Example text

Sometimes API keys will be passed simply as a query parameter, but the Authorization header would also be an appropriate place for such information. info HTTP Basic Authentication The simplest approach to authorization is HTTP Basic authentication (for more details, see the RFC), which requires the user to supply a username and password to identify himself. Since this approach is so widespread, it is well supported in most platforms, both client and server. Do beware, though, that these credentials can easily be inspected and reused maliciously, so this approach is appropriate only on trusted networks or over SSL.

Div> You can see that PHP simply checks if it has been given some search criteria (or indeed any data in the $_GET superglobal) and if not, it displays the empty form. If there was data, then it would process it (although probably in a more interesting way than this trivial example does). category=technology&rows=20 Having the data visible on the URL is a design choice. When this happens, a user can easily bookmark or share this URL with others, which is sometimes very useful, for example, to bookmark a particular set of search results, or a product page.

Info header denotes what kind of data can be found in the body. com&display_name=LornaJane In this example, you can see the data in the body, with the Content-Type and Content-Length headers set appropriately so that the server can decode the response (more about content negotiation in Chapter 3). Next we’ll look at the server side of the conversation. PHP knows how to handle form data, so it can parse this out and place the fields into $_POST, so it will be ready for use in the script. php else: echo "New user email: " .
