The getParameter () method is one of the most widely used HTTP request methods to request resources from a server through a client, such as a browser. Since the contents or files of the page transmitted are requested by means of URL, it is also essential to indicate the parameters of the URL.\n<\/p>\n

\nGeneral information<\/span>
\n<\/h2>\n

Communication between clients and servers on the Internet is carried out mainly through the HTTP protocol (Hypertext Transfer Protocol). This enables a data exchange by request and response. A client could be, for example, a user's web browser; the server provides an HTML page that is loaded by the user's browser. The two most widely used methods to allow this type of communication are GET and POST.\n<\/p>\n

\nGET request<\/span>
\n<\/h2>\n

If a client uses the HTTP protocol on a web server to request a certain resource, the client sends certain GET parameters to the server using the requested URL. These parameters are pairs of names and their corresponding values, the so-called name-value pairs. These are appended to the URL with a "?" and it tells you to sign and tell the server what resources you are referring to. The name and value are always separated by the "=" sign.\n<\/p>\n

The syntax is as follows:\n<\/p>\n

\nhttp:\/\/www.domain.com\/index.html*?name1=value1\n<\/pre>\n
Not only individual parameters, but also various, as well as complete lists, can be transmitted to the server. In this case, the different parameters are separated by the sign "&".\n<\/p>\n
\nhttp:\/\/www.domain.com\/index.html*?name1=value1&name2=value2\n<\/pre>\n
If the request is syntactically correct, the server sends a response. Initially, it contains some status information about the request. This can be, for example, if the requested resource is enabled or not or when the request was made. The server does not send the resource to the client first, but tells it where the resource can be found. The browser follows the instructions and requests the resource from the server. At this point, the browser briefly loads the resource based on the location-based information provided to it by the server. The reason for this is that the HTTP protocol only allows one-way communication. Each request only receives one response.\n<\/p>\n
\nComments on the GET parameter<\/span>
\n<\/h2>\n
Requests that use getParameter () have certain properties and disadvantages. Since the data is transmitted via the URL, it is advisable to only use the GET parameter to request files that are not security relevant.\n<\/p>\n
The following properties characterize the GET parameter\n<\/p>\n
