Summary of HTTP Protocol Learning

HTTP protocol is the abbreviation of Hyper Text Transfer Protocol (Hypertext transfer Protocol), which is characterized by:

1. Concise and fast

two。 Flexible

3. Stateless

4. No connection

5. Support the BPX S and Cmax S modes.

HTTP uses uniform resource identifiers (Uniform Resource Identifiers, URI) to transfer data and establish connections

The difference between GET and POST requests:

Submitted by GET:GET, the requested data will be appended to the URL (that is, put the data in the HTTP protocol header)

POST submission: place the submitted data in a package that is a HTTP package

GET: specific browsers and servers have limits on URL length

POST: since values are not passed through URL, the data is theoretically unlimited

The security of POST is higher than that of GET
