发送JSON到Rails REST API

问题描述：

我有一个Rails应用程序，包含文章和用户。所以我希望用户可以从客户端应用程序用json对象注销并获取所有文章也用json对象。发送JSON到Rails REST API

但是，我有一些问题。控制台输出：

Started POST "/articles" for 127.0.0.1 at 2012-03-30 17:29:25 +0200 
Processing by ArticlesController#create as JSON 
    Parameters: {"id"=>1, "article"=>{"id"=>1}} 
WARNING: Can't verify CSRF token authenticity 
Completed 401 Unauthorized in 1ms

而这里的Controler：

class ArticlesController < ApplicationController 
    before_filter :authenticate_user!, :except => [:show, :index] 

    # GET /articles 
    # GET /articles.json 
    def index 
    @articles = Article.all 

    respond_to do |format| 
     format.html # index.html.erb 
     format.json { render json: @articles } 
    end 
    end 

    # GET /articles/1 
    # GET /articles/1.json 
    def show 
    @article = Article.find(params[:id]) 

    respond_to do |format| 
     format.html # show.html.erb 
     format.json { render json: @article } 
    end 
    end 

    # GET /articles/new 
    # GET /articles/new.json 
    def new 
    @article = Article.new 

    respond_to do |format| 
     format.html # new.html.erb 
     format.json { render json: @article } 
    end 
    end 

    # GET /articles/1/edit 
    def edit 
    @article = Article.find(params[:id]) 
    end 

    # POST /articles 
    # POST /articles.json 
    def create 
    @article = Article.new(params[:article]) 

    respond_to do |format| 
     if @article.save 
     format.html { redirect_to @article, notice: 'Article was successfully created.' } 
     format.json { render json: @article, status: :created, location: @article } 
     else 
     format.html { render action: "new" } 
     format.json { render json: @article.errors, status: :unprocessable_entity } 
     end 
    end 
    end 

    # PUT /articles/1 
    # PUT /articles/1.json 
    def update 
    @article = Article.find(params[:id]) 

    respond_to do |format| 
     if @article.update_attributes(params[:article]) 
     format.html { redirect_to @article, notice: 'Article was successfully updated.' } 
     format.json { head :no_content } 
     else 
     format.html { render action: "edit" } 
     format.json { render json: @article.errors, status: :unprocessable_entity } 
     end 
    end 
    end 

    # DELETE /articles/1 
    # DELETE /articles/1.json 
    def destroy 
    @article = Article.find(params[:id]) 
    @article.destroy 

    respond_to do |format| 
     format.html { redirect_to articles_url } 
     format.json { head :no_content } 
    end 
    end 
end

和模型：

class Article < ActiveRecord::Base 

end

我送看起来像这样JSON：

{ 
    "id" : 1 
}

路线

    articles GET  /articles(.:format)      articles#index 
         POST  /articles(.:format)      articles#create 
      new_article GET  /articles/new(.:format)     articles#new 
      edit_article GET  /articles/:id/edit(.:format)    articles#edit 
       article GET  /articles/:id(.:format)     articles#show 
         PUT  /articles/:id(.:format)     articles#update 
         DELETE  /articles/:id(.:format)     articles#destroy 
        root   /          articles#index

现在我的问题是：我的JSON对象是否错误，或者我错过了什么，比如CSRF令牌？

答

您需要确保CSRF令牌随每个JSON HTTP请求一起提交。这就是我的做法：

$.ajaxSetup({ 
    beforeSend: function(xhr) { 
    xhr.setRequestHeader('X-CSRF-Token', $('meta[name="csrf-token"]').attr('content')); 
    } 
});
