What is a post request?
The purpose of a Post request is to make a change on the Server.
Given the post request below:
On the request line we have POST instead of GET followed by the resource location on the server in this case “/post” then followed by the HTTP/1.1 protocol version.
Next line we have the Host location URI, we hit enter to put a blank space then followed by the Content-Length: 32 bytes. We get the number of bytes from the data we wish to POST.
This data is “firstname=Chris&language=English. each letter is 1 byte. There are 32 letters therefore 32 bytes.
Enter the wrong number of bytes and we get a 400 status code.
Data is included in the request body or payload, after a blank line that follows the headers in a HTTP POST request.
