Question

我正在尝试向我的Rails 3应用程序发出一个简单的PUT JSON请求：

$.ajax({type: 'PUT', url: '/controlpanel/custom_forms/1', data: { hello: 'world' }, contentType: 'json'})

不知何故，未收到数据且params仅包含ID。这是在服务器端：

Started PUT "/controlpanel/custom_forms/1" for 127.0.0.1 at 2012-05-22 23:05:25 -0400
Processing by Controlpanel::CustomFormsController#update as */*
  Parameters: {"id"=>"1"}

我期待Parameters成为{"id"=>"1", "hello"=>"world"}

Chrome中的请求看起来很好：

请求标题

PUT /controlpanel/custom_forms/1 HTTP/1.1
Host: localhost:3000
Connection: keep-alive
Content-Length: 11
Origin: localhost:3000

Accept: */*

Accept-Language: en-US,en;q=0.8
Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3

请求有效负载

hello=world

我做错了什么？

Answer 1

我犯了两个错误。首先，contentType必须设置为application/json，而不仅仅是json。其次，data必须使用JSON.stringify({...})手动序列化。

如何在rails中获取JSON ajax请求的数据？
