Http methods

HTTP Methods

1.  GET

·       It is used at the time of retrieving the data from the server.

·       It is safe and idempotent

·       Idempotent means at the time of first request and after any number of request the data or the output will be the same.

·       It doesn't have the body.

·       We can send only the character data or String data we can’t send the binary data, because the request doesn’t have the body.

·       Only through URI we can send the data

·       Bookmarking is possible (because complete information will be there in URI only)

·       Limited amount of data only we can send till 2kb data only.

·       Less security

·       Caching of the data is possible only with the GET REQUEST

2.  PUT

·       It is used for either updating or creating the data.

·       While sending the put request it is mandatory to send the identity of the resource.

·       It is also a safe and idempotent.

·       While sending the put request we can send the data in 3 ways

1.  Query parameter

2.  Uri

3.  Request body.

·       The put request will be having the request body. So we can also send the binary data.

3.  POST

·       It is used for updating or creating but recommended to use for updating only.

·       It is not a safe and it is non-idempotent.

·       While sending the post request the end user no need to send the identity of the resource. So the Server treats that every post request is new request only.

·       While sending the put request we can send the data in 3 ways

1.  Query parameter
