Generally in the browser input URL access to resources are through get mode;

In the form submission, the method can be used to specify whether a commit is a GET or post, and the default is get commit.

A URL address, which is used to describe a resource on a network, and the HTTP get,post,put,delete corresponds to this resource search, change, increase, delete 4 operations. Get is typically used to get/query resource information, and post is typically used to update resource information.

Other differences:

1. Get uses URL or cookie to pass the parameter. And the post puts the data in the body.

2. Get URLs are limited in length, then the post data can be very large.

3. Post is safer than get because the data is not visible on the address bar.
