There are 15 HTTP Request Methods. According to the HTTP standard, HTTP requests can use multiple request methods. HTTP 1.0 defines three request methods: GET, POST and HEAD methods. HTTP1.1 added five new request methods: OPTIONS, PUT, DELETE, TRACE and CONNECT methods.
| serial number | method | description |
|---|---|---|
| 1 | GET | Request the specified page information and return the entity body. |
| 2 | HEAD | Similar to a get request, except that there is no specific content in the returned response, which is used to get the header |
| 3 | POST | Submit data to the specified resource for processing requests (such as submitting a form or uploading a file). 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 pipe mode. |
| 7 | OPTIONS | Allows the client to view the performance of the server. |
| 8 | TRACE | Echoes the request received by the server, mainly for testing or diagnosis. |
| 9 | PATCH | The entity contains a table, which describes the difference 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. |
| 14 | WRAPPED | Allow clients to send encapsulated requests. |
| 15 | Extension-mothed | Under the premise of not changing the protocol, another method can be added. |
