HTTP is an acronym for Hyper Text Transfer Protocol, a transfer protocol used to transfer hypertext from World Wide Web servers to local browsers.

HTTP is a TCP/IP-based communication protocol for transferring data (HTML files, image files, query results, etc.).

HTTP request method

According to the HTTP standard, HTTP requests can use a variety of request methods.

HTTP 1.0 defines three request methods: GET, POST and HEAD.

HTTP 1.1 adds six new request methods: OPTIONS, PUT, PATCH, Delete, TRACE, and CONNECT.

serial number method Description 1 GET Requests the specified page information and returns the entity body. 2 HEAD Similar to GET request, except there is no specific content in the returned response, which is used to get header 3. POST Submit a request for data to a specified resource for processing (for example, submit a form or upload a file). The data is contained in the request body. POST requests may result in the creation of new resources and/or modification of existing resources. 4 PUT Data transferred from a client to a server replaces the contents of a specified document. 5 Delete Requests the server to delete the specified page. 6 CONNECT HTTP/1.1 is reserved for proxy servers that can change connections to pipe mode. 7 OPTIONS Allows clients to view server performance. 8 TRACE Echo requests received by the server, primarily for testing or diagnostics. 9 PATCH Is a complement to the PUT method, used to locally update a known resource.
