获取内容请求类型 [英] Get Content Type of Request

问题描述

要查找传入的内容类型，请文档说明：

To find the incoming content type, docs say:

 request.headers["Content-Type"] # => "text/plain"

但我通过反复试验发现，这不起作用，但这样做：

But I found by trial-and-error, that doesn't work, but this does:

 request.headers["CONTENT_TYPE"]=='application/json'

那么最强大+便携的方式是什么？

So what's the most robust+portable way to do it?

推荐答案

我通常会去 request.format 和 request.content_type 来阅读这些标题字段。

I would usually go for request.format and request.content_type for reading these header fields.
