从android发布到Ruby on Rails应用程序

Question

所以我想从我正在写的Android应用程序发布到rails应用程序.我能够从rails app中发布成功.我还能够使用名为Simple Rest客户端的chrome add成功发布.

当我尝试从Android应用程序发布时,它会点击rails应用程序,但会创建一个空帖子.rails没有接收任何输入数据.

我读到第三方应用程序只能从Rails应用程序获取,具体取决于身份验证,以确保这不是我遇到的问题我将此添加到我的Rails配置.

# de-activate tolken auth
config.action_controller.allow_forgery_protection = false

在这一点上,我不确定我的问题在哪里,我的Rails后端或我的Android客户端.

好的,所以我想要触及的控制器中的Rails post方法就在这里

# POST /orders
  # POST /orders.json
  def create
    @order = Order.new(params[:order])

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

这是用于发送Post Request的Android java代码.这是传递我尝试POST的用户输入数据的方法

private void postInformationtoAPI() {

                showToast("POSTING ORDER");
                List<NameValuePair> apiParams = new ArrayList<NameValuePair>();
                apiParams.add(new BasicNameValuePair("drinks_id", GlobalDrinkSelected));
                apiParams.add(new BasicNameValuePair("name", GlobalEditTextInputName));
                apiParams.add(new BasicNameValuePair("paid" , GlobalIsPaid));

                bgtPost = new BackGroundTaskPost(MAP_API_URL_POST_ORDER, "POST", apiParams);
                bgtPost.execute();

                goToOrderCompleted();

            }

这是传递给HTTP POST的类.

public class BackGroundTaskPost extends AsyncTask<String, String, JSONObject> {

     List<NameValuePair> postparams = new ArrayList<NameValuePair>();
     String URL = null;
     String method = null;

     static InputStream is = null;
     static JSONObject jObj = null;
     static String json = "";

     public BackGroundTaskPost(String url, String method, List<NameValuePair> params) {
      this.URL = url;
      this.postparams = params;
      this.method = method;

      for (int i = 0; i < postparams.size(); i++){
          String test = postparams.get(i).toString();
          Log.d("This is in the lisht:", test);
      }
     }

     @Override
     protected JSONObject doInBackground(String... params) {
      // TODO Auto-generated method stub
      // Making HTTP request
      try {
       // Making HTTP request
       // check for request method

       if (method.equals("POST")) {
        // request method is POST
        // defaultHttpClient

           DefaultHttpClient httpClient = new DefaultHttpClient();
           HttpPost httpPost = new HttpPost(URL);
           httpPost.setEntity(new UrlEncodedFormEntity(postparams, HTTP.UTF_8));
           Log.i("postparams : ", postparams.toString());
           httpPost.setHeader("Content-Type", "application/json");
           httpPost.setHeader("Accept", "application/json");

           HttpResponse httpResponse = httpClient.execute(httpPost);
           HttpEntity httpEntity = httpResponse.getEntity();
           is = httpEntity.getContent();

       } else if (method == "GET") {
        // request method is GET
        DefaultHttpClient httpClient = new DefaultHttpClient();
        String paramString = URLEncodedUtils
          .format(postparams, "utf-8");
        URL += "?" + paramString;
        HttpGet httpGet = new HttpGet(URL);

        HttpResponse httpResponse = httpClient.execute(httpGet);
        HttpEntity httpEntity = httpResponse.getEntity();
        is = httpEntity.getContent();
       }

      } catch (UnsupportedEncodingException e) {
       e.printStackTrace();
      } catch (ClientProtocolException e) {
       e.printStackTrace();
      } catch (IOException e) {
       e.printStackTrace();
      }

      try {
          Log.i("Logging out *is* before beffered reader", is.toString());
       BufferedReader reader = new BufferedReader(new InputStreamReader(
         is, "utf-8"), 8);
       Log.i("Logging out *is* after beffered reader", is.toString());
       StringBuilder sb = new StringBuilder();
       String line = null;
       while ((line = reader.readLine()) != null) {
        sb.append(line + "\n");
       }
       is.close();
       json = sb.toString();
       Log.i("json: ",json);
      } catch (Exception e) {
       Log.e("Buffer Error", "Error converting result " + e.toString());
      }

      // try parse the string to a JSON object
      try {
       jObj = new JSONObject(json);
      } catch (JSONException e) {
       Log.e("JSON Parser", "Error parsing data TEST " + e.toString());
      }

      // return JSON String
      return jObj;

     }
    }

这是上述类中postparams的日志,所以我知道实际上正在发送数据

04-03 21:36:23.994: I/postparams :(690): [drinks_id=41, name=Dave, paid=True]

这就是Log Cat作为服务器响应显示的内容

04-03 20:56:08.247: I/json:(690): {"created_at":"2013-04-03T20:56:06Z","drinks_id":null,"id":1351,"name":null,"paid":null,"served":null,"updated_at":"2013-04-03T20:56:06Z"}

我真的很难理解这个问题在哪里,并且已经坚持了很长一段时间.任何见解都会非常感激.如果需要更多信息,请大声喊叫.

Answer 1

您正在设置JSON的内容类型,但实际上并未发送JSON,您正在发送标准的POST网址编码参数.

您需要实际发送一个JSON对象:

JSONObject params = new JSONObject();
params.put("drinks_id", GlobalDrinkSelected);
params.put("name", GlobalEditTextInputName);
params.put("paid", GlobalIsPaid);

StringEntity entity = new StringEntity(params.toString());
httpPost.setEntity(entity);
