POST和PUT之间的区别在于PUT请求是幂等的。 也就是说,多次调用相同的PUT请求将始终产生相同的结果。 相反,重复调用POST请求具有多次创建相同资源的副作用。 2.幂等性 幂等是一个数学与计算机学概念,常见于抽象代数中。 幂等是使公式f(x)=f(f(x))能够成立的数学性质。 相关阅读:幂等 - 术语表 | MDN 3.POST...
在非资源风格下,POST可以用于任何有副作用的事情。 另外一个区别是PUT应该是幂等的 - 对于同一个URL,同一个数据的多个PUT应该没问题,而多个POST可能会创建多个对象,或者你的POST动作不管它是什么。 链接地址:http://www.djcxy.com/p/1075.html
Http protocol (RFC2616) defines the two verbs: get / put. It seems a little confusion that both of them send data to server. What's the different? The RFC itself explains the difference: The fundamental difference between the POST and PUT requests is reflected in the different meaning of ...
If the PUT request URI refers to an existing resource, then an update operation must be performed; otherwise, a create operation must be performed.The POST method is used to create new resource on the server. If the request URI refers to an existing resource, then POST updates the resource...
HTTP POST vs PUT Method The fundamental difference between the HTTP POST andPUTrequests is reflected in the different meaning of the Request-URI. The URI in a POST request identifies the resource that will handle the enclosed entity. In contrast; the URI in a PUT request identifies the entity...
The PUT Method PUT is used to send data to a server to create/update a resource. The difference between POST and PUT is that PUT requests are idempotent. That is, calling the same PUT request multiple times will always produce the same result. In contrast, calling a POST request repeatedly...
The HTTP PUT request method creates a new resource or replaces a representation of the target resource with the request payload. The difference betweenPUTandPOSTis thatPUTis idempotent: calling it once or several times successively has the same effect (that is nosideeffect), whereas successive id...
So today, we thought we would explore the difference between HTTP and HTTPS, what they mean, and why it might be time for you to move to HTTPS. What is HTTP?# HTTP stands for Hypertext Transfer Protocol. It is a protocol used by a client and server that allows you to communicate ...
POST 传输实体主体 POST 主要用来传输数据,而 GET 主要用来获取资源。 更多POST 与 GET 的比较请见第九章。 PUT 上传文件 由于自身不带验证机制,任何人都可以上传文件,因此存在安全性问题,一般不使用该方法。 PUT /new.html HTTP/1.1 Host: example.com ...
The resolution to issue #1131 was that certain request types (POST, PUT, PATCH) are no longer allowed to have no body. However, this is not in line with the HTTP specifications. Nowhere in the HTTP spec is mentioned that a body is requir...
