Get and Post differences:

1, get request, the parameters are written directly on the access path. Simple operation, but easy to be seen by the outside, security is not high, address up to 255 bytes;

2, POST request, put the parameters inside the body. Post request operation is relatively complex, need to separate parameters and addresses, but high security, parameters placed inside the body, not easily captured.
