本文详细解释了HTTP请求中GET与POST的区别。GET用于获取远程数据，不应产生副作用，可能被爬虫随意调用；POST用于提交数据进行处理，如通过HTML表单提交数据，可能导致资源创建或更新。

What is the difference between POST and GET HTTP requests?

GET and POST are two different types of HTTP requests.

According to Wikipedia:

GET requests a representation of the specified resource. Note that GET should not be used for operations that cause side-effects, such as using it for taking actions in web applications. One reason for this is that GET may be used arbitrarily by robots or crawlers, which should not need to consider the side effects that a request should cause.

and

POST submits data to be processed (e.g., from an HTML form) to the identified resource. The data is included in the body of the request. This may result in the creation of a new resource or the updates of existing resources or both.

So essentially GET is used to retrieve remote data, and POST is used to insert/update remote data.
