There are 15 HTTP request methods. According to the HTTP standard, HTTP requests can use multiple request methods. HTTP1.0 defines three request methods: GET, POST and HEAD. HTTP1.1 adds five new request methods: OPTIONS, PUT, DELETE, TRACE and CONNECT.
| Serial number | method | describe |
|---|---|---|
| 1 | GET | Request the specified page information and return the entity body. |
| 2 | HEAD | Similar to the get request, except that the returned response does not have specific content, used to obtain the header |
| 3 | POST | Submit data to the specified resource to process the request (such as 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 sent from the client to the server replaces the content of the specified document. |
| 5 | DELETE | Request the server to delete the specified page. |
| 6 | CONNECT | The HTTP/1.1 protocol is reserved for proxy servers that can change the connection to a pipeline mode. |
| 7 | OPTIONS | Allow the client to view the performance of the server. |
| 8 | TRACE | Echo the request received by the server, mainly used for testing or diagnosis. |
| 9 | PATCH | The entity contains a table 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 | Disconnect the link relationship. |
| 14 | WRAPPED | Allow the client to send an encapsulated request. |
| 15 | Extension-mothed | Additional methods may be added without changing the protocol. |
