$ _POST与$ _SERVER ['REQUEST_METHOD'] =='POST' [英] $_POST vs. $_SERVER['REQUEST_METHOD'] == 'POST'

问题描述

有人将我的Snipplr提交之一称为废话"，因为我使用了if ($_SERVER['REQUEST_METHOD'] == 'POST')而不是if ($_POST)

Some guy called one of my Snipplr submissions "crap" because I used if ($_SERVER['REQUEST_METHOD'] == 'POST') instead of if ($_POST)

检查请求方法对我来说似乎更正确，因为那是我真正想要做的.两者之间在操作上有区别吗?还是仅仅是代码清晰性问题?

Checking the request method seems more correct to me because that's what I really want to do. Is there some operational difference between the two or is this just a code clarity issue?

推荐答案

好吧，他们确实做的不一样.

Well, they don't do the same thing, really.

$_SERVER['REQUEST_METHOD']包含请求方法(惊奇).

$_SERVER['REQUEST_METHOD'] contains the request method (surprise).

$_POST包含任何帖子数据.

POST请求可能不包含POST数据.

It's possible for a POST request to contain no POST data.

我检查了请求方法-实际上，我从未想过要测试$_POST数组.不过，我检查了必填字段.因此，空的发布请求会给用户带来很多错误消息-这对我来说很有意义.

I check the request method — I actually never thought about testing the $_POST array. I check the required post fields, though. So an empty post request would give the user a lot of error messages - which makes sense to me.
