- HEAD Method.
- POST Method.
- PUT Method.
- DELETE Method.
- CONNECT Method.
- OPTIONS Method.
- TRACE Method.
How many HTTP methods
HTTP methods: API developers typically only use GET, PUT, or POST, but the official HTTP Request Method registry lists 39 total HTTP verbs, each providing a method for powerful interactions.
HTTP request methods
The GET Method
- GET is used to request data from a specified resource.
- GET is one of the most common HTTP methods.
- POST is used to send data to a server to create/update a resource.
- POST is one of the most common HTTP methods.
- PUT is used to send data to a server to create/update a resource.
The POST Method
POST is used to send data to a server to create/update a resource.
The data sent to the server with POST is stored in the request body of the HTTP request:POST /test/demo_form.php HTTP/1.1
Host: w3schools.com
name1=value1&name2=value2
POST is one of the most common HTTP methods.
Some other notes on POST requests:
- POST requests are never cached
- POST requests do not remain in the browser history
- POST requests cannot be bookmarked
- POST requests have no restrictions on data length
The PUT Method
PUT is used to send data to a server to create/update a resource.
The difference between POST and PUT is that PUT requests are idempotent. That is, calling the same PUT request multiple times will always produce the same result. In contrast, calling a POST request repeatedly have side effects of creating the same resource multiple times.
The HEAD Method
HEAD is almost identical to GET, but without the response body.
In other words, if GET /users returns a list of users, then HEAD /users will make the same request but will not return the list of users.
HEAD requests are useful for checking what a GET request will return before actually making a GET request – like before downloading a large file or response body.
The DELETE Method
The DELETE method deletes the specified resource.
The OPTIONS Method
The OPTIONS method describes the communication options for the target resource.
