Java的：HTTP发布创建新的＆QUOT;产品＆QUOT;在Ruby on Rails应用 [英] Java: HTTP Post to create new "Product" in a Ruby on Rails application

问题描述

使用Apache HttpClient的android上，我怎么使用HttpPost送on Rails应用程序数据到一个REST风格的Ruby。

Using the Apache HttpClient on android, how do I send data to a RESTfull Ruby on Rails app using HttpPost.

这是我的控制器：

# POST /products
  def create

    @product = Product.new(params[:product])

    respond_to do |format|
      if @product.save
        flash[:notice] = 'Product was successfully created.'
        format.html { redirect_to(@product) }
        format.xml  { render :xml => @product, :status => :created, :location => @product }
      else
        format.html { render :action => "new" }
        format.xml  { render :xml => @product.errors, :status => :unprocessable_entity }
      end
    end
  end

这是我的Java code。我应该传递数据的URL名称，或者我需要设置在别的地方？ （httpost.setEntity吧？）最后，我将使用JSON但现在我只是想获得它，所以我实际上可以调用Rails的创造的方法。 Rails是获得职位，但从来没有在创造的方法执行任何code

And this is my Java Code. Should I be passing the data in the URL name, or do I have to set it somewhere else? (httpost.setEntity perhaps?) Eventually I will be using JSON but for now I just want to get it so I can actually call the "create" method in Rails. Rails is getting the POST but never executes any code in the "create" method

  HttpClient httpclient = new DefaultHttpClient();

  HttpPost httppost = new HttpPost("http://192.168.0.100:3000/products/new");

  HttpResponse response = httpclient.execute(httppost);

我很卡住，将AP preciate如果有人可以点我在正确的方向。

I am quite stuck and would appreciate if someone could point me in the right direction.

推荐答案

我增加了以下我的POST请求和它的工作就像一个魅力。

I added the following to my POST request and it worked like a charm.

httppost.addHeader("Content-Type","application/json");
