1. The most intuitive difference is the semantic difference. Get is used to obtain data, and post is used to submit data.
2. The get parameter has a length limit (limited by the length of the url), but the post has no limit
Let’s talk about the first point in detail, and let’s talk about the conclusion first: reversing the two will cause very bad results.
For example, a web page address is: www.taobao.com?itemId=123
You send it to a friend and say that this thing is cool! This is the most correct way to obtain data using get, which is conducive to dissemination.
But if you use a post request to obtain a product page, and the URL is still http://www.taobao.com, then it makes no sense for you to share this URL with your friends.
On the other hand, if you use www.weibo.com?uid=1&content=haha&token=xxxxxxxxxx
to post a Weibo, and this URL is seen by others.
Then he can just copy the URL there and post it on Weibo for you. Isn’t that unreasonable?
