Difference between GET and POST Method
GET and POST are HTTP verbs used to query the server for some information.Both can be used to achieve same goal but incorrect choice of HTTP verbs may lead to unexpected outcomes.
GET is a read-only operation which can be used for safe actions. It can be repeated without affecting the state of the resource.It is used to retrieve current state of the resource from the server.
POST is a read-write operation and may change the state of the resource and provoke side effects on the server.It is used to initialize the state of a new resource using given URL. We can use POST when we are dealing with sensitive data and when we have long requests.
