HTTP Methods
HTTP (Hypertext Transfer Protocol) is a protocol used for sending and receiving data over the internet. It defines a set of request methods to indicate the desired action to be performed on the identified resource. Here are the most commonly used HTTP methods:
GET: This method is used to retrieve information from the server. It is the most common HTTP method and is used to retrieve the contents of a specified resource.
POST: This method is used to submit information to the server. It is typically used to send data to the server for processing, such as when submitting a form or uploading a file.
PUT: This method is used to update an existing resource on the server. It is used to upload a new version of a file or to update a database record.
DELETE: This method is used to delete a resource on the server. It is used to remove a file or a database record.
HEAD: This method is similar to GET, but it only returns the headers of the response, rather than the actual content of the resource.
PATCH: This method is used to update a resource partially. It is used to update specific fields of a resource.
OPTIONS: This method is used to retrieve information about the communication options available for a specific resource.
CONNECT: This method is used to establish a network connection to a specific resource, such as a proxy server.
TRACE: This method is used to retrieve a diagnostic trace of the request message as it travels through the various layers of communication.
Link: This method is used to establish a link between the current resource and other resources.
These are the most common methods used in HTTP, but it should be noted that the HTTP/2 and HTTP/3 protocol have added new methods and/or change the way they are used.
