According to the HTTP standard, HTTP requests can use various request methods.
HTTP1. defined three request methods: GET, POST, and HEAD methods.
HTTP1.1 added five request methods: OPTIONS, PUT, DELETE, TRACE, and CONNECT methods.
| Number | Method | Description |
|---|---|---|
| 1 | GET | Requests the specified page information and returns the entity body. |
| 2 | HEAD | Similar to a GET request, except that the response returned does not contain specific content, used to obtain headers. |
| 3 | POST | Submits data to the specified resource for processing (e.g., submitting a form or uploading a file). The data is included in the request body. POST requests may result in the creation of new resources and/or the modification of existing resources. |
| 4 | PUT | The data transmitted from the client replaces the content of the specified document. |
| 5 | DELETE | Request the server to delete the specified page. |
| 6 | CONNECT | Reserved in the HTTP/1.1 protocol for proxy servers that can tunnel connections. |
| 7 | OPTIONS | Allows the client to see the server's capabilities. |
| 8 | TRACE | Echoes the received request, mainly used for testing or diagnostics. |
| 9 | PATCH | Contains a list in the entity that describes the differences from the original content represented by the URI. |
| 10 | MOVE | Request the server to move the specified page to another network address. |
| 11 | COPY | Request the server to copy the specified page to another network address. |
| 12 | LINK | Request the server to establish a link relationship. |
| 13 | UNLINK | Break the link relationship. |
| 14 | WRAPPED | Allows the client to send wrapped requests. |
| 15 | Extension-method | Additional methods can be added without changing the protocol. |
