如何让Rails根据标头使用json进行响应 [英] How to get Rails to respond with json based on headers

问题描述

我正在使用Rails 4构建API，并且在我的控制器中使用respond_to来区分html和json请求，它们都可以正常工作.在Postman中测试我的API时，我添加了以下标头:Content-Type: application/json，但在我的请求中，我仍然需要在其末尾添加.json，如下所示:https://myapi.com/api/users.json否则，Rails甚至会以html响应尽管存在上述标头.

I'm building an API with Rails 4 and in my controller I'm using respond_to to differentiate between html and json request which all works fine. While testing my API in Postman, I've added the following header: Content-Type: application/json but in my request I still need to add .json at the end of it like so: https://myapi.com/api/users.json otherwise Rails will respond with html even though the aforementioned header is present.

我的问题是这样:Rails是否可以识别Content-Type: application/json标头并用json响应，而无需我像下面这样使用url中的.json部分:https://mypai.com/api/users?

My question is this: is there a way that Rails can recognise the Content-Type: application/json header and respond with json without me using the .json part in the url like so: https://mypai.com/api/users?

推荐答案

您还需要将Accept标头设置为Accept: application/json

You also need to set the Accept header to Accept: application/json
