php - laravel HTTP请求的疑问，put patch delete options存在的意义，已经应用场景是什么

Question

HTTP请求类型，put patch delete options这些有什么用？从来没用过啊。
平时开发都是get post请求，感觉get post完全可以进行Mysql的增删改查操作。
put patch delete options这几种类型有什么用处呢?应用场景是什么？应该怎么写呢？
get请求一般是url传参数，表单method当然也可以写get；
post请求一般是表单提交；

Answer 1

These are standard http predicates

• GET Get resources

• POST Create Resource

• PUT edit/update resources (complete resource fields need to be submitted)

• PATCH edit/update resources (you can submit fields that need to be updated)

• DELETE Delete resources

• OPTIONS Which request verbs are allowed by the server

Answer 2

These are commonly used in the recently popular RestFul mode. In addition, HTML forms only support two request methods: POST and GET. PUT, PATCH and DELETE are fake HTTP request methods in Laravel. You need to add <input type="hidden" name="_method" value="PUT（PATCH、DELETE）"> to the form to take effect. Also Configure routing.

Answer 6

Get and post can of course satisfy all operations.
Using put, patch and delete makes it look simpler and easier to understand.
patch /item/1 is to modify the data with id 1.
get /item/1 finds the data with id 1.
delete /item/1 deletes the data with id 1
