HTTP 和 REST 有什么区别? [英] What is the difference between HTTP and REST?

问题描述

在阅读了大量有关 REST 和 SOAP 之间差异的信息后，我的印象是 REST 只是 HTTP 的另一个词.有人能解释一下 REST 为 HTTP 添加了哪些功能吗?

After reading a lot about the differences between REST and SOAP, I got the impression that REST is just another word for HTTP. Can someone explain what functionality REST adds to HTTP?

注意:我不是在寻找 REST 与 SOAP 的比较.

Note: I'm not looking for a comparison of REST versus SOAP.

更新:感谢您的回答.现在我已经很清楚 REST 只是关于如何使用 HTTP 的一组规则.因此我发布了关于 这些约定的优点是什么 .

Update: Thanks for your answers. Now it has become clear to me that REST is just a set of rules about how to use HTTP. Hence I posted a follow-up about what the advantages of these conventions are .

注意:我现在掌握了REST的含义；如 埃米尔·伊万诺夫 备注，REST 意味着按其应有的方式使用 HTTP.但是，我不确定这是否值得拥有一个自己的术语，而且我当然不会对其进行大肆宣传.

Note: I now grasp the meaning of REST; as Emil Ivanov remarks, REST means using HTTP the way it's meant to be. However, I'm not sure whether this deserves a term of its own, and I certainly don't get the hype around it.

推荐答案

不，REST 是 HTTP 应该使用的方式.

No, REST is the way HTTP should be used.

今天我们只使用了一小部分 HTTP 协议的方法——即 GET 和 POST.REST 方法是使用协议的所有方法.

Today we only use a tiny bit of the HTTP protocol's methods – namely GET and POST. The REST way to do it is to use all of the protocol's methods.

例如，REST 规定使用 DELETE 擦除 URI 后面的文档(无论是文件、状态等)，而使用 HTTP，您会误用 GET 或 POST 查询，如 ...product/?delete_id=22.

For example, REST dictates the usage of DELETE to erase a document (be it a file, state, etc.) behind a URI, whereas, with HTTP, you would misuse a GET or POST query like ...product/?delete_id=22.
