HTTP request mode

1. GET

2. HEAD

3. PUT

4. DELETE

5. POST

6. OPTIONS

Get: Send a request to get some resources on the server, the resource is put back to the client through HTTP header and rendering data, and the GET request never contains rendering data;

Head: Essentially the same as get, but head does not render data with only HTTP header information; (Imagine a business scenario: to determine whether a resource exists, we usually use get, but the head here is more explicit.) ）

Put:put, similar to post, sends data to the server, but the put specifies where the resource is stored;

Delete: Deletes a resource;

Post: Providing data to the server;

Options: It is used to get the methods supported by the current URL. If the request succeeds, it contains a header named "Allow" in the HTTP header, which is the supported method, such as "GET, POST." (interesting but less used)
