According to http standards, HTTP requests can use a variety of 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 methods.
| Serial number | Method | Describe |
|---|---|---|
| 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 to get the header |
| 3 | POST | Submit data to a specified resource for processing requests, such as submitting forms or uploading files. T he data is included in the request body. POST requests may result in the establishment of new resources and/or modifications to existing resources. |
| 4 | PUT | The data transferred from the client to the server supersedes the contents of the specified document. |
| 5 | DELETE | Ask the server to delete the specified page. |
| 6 | CONNECT | The HTTP/1.1 protocol is reserved for proxy servers that can change connections to a pipeline. |
| 7 | OPTIONS | Allows clients to view the performance of the server. |
| 8 | TRACE | Echo requests received by the server, primarily for testing or diagnostics. |
