处理HTTP GET /删除Android使用REST [英] Handling HTTP Get/ Delete Android using REST

问题描述

我米实施的Andr​​oid基于REST的HTTP服务器。该服务器响应GET，DELETE和POST请求。两款Android设备之间使用HTTP POST（我米使用服务，其中设备保持侦听端口和后下一个设备上，并继续这样跌下去的）。

我米测试GET和使用Mozilla海报删除。我要补充一个单独的插座/端口来处理一样吗？因为当我现在尝试，有时我得到超时错误或没有找到回应。但是，我能够看到的logcat窗口服务器响应。请帮帮我。
code处理GET请求：

 如果（method.equals（GET））
 {
   如果（checkFileExisting（））
     {
       读者的BufferedReader =新的BufferedReader（新的FileReader（新文件（getFilesDir（）+文件分割符+script.json）））;
       串读;
       StringBuilder的建设者=新的StringBuilder（）;
         而（（读= reader.readLine（））！= NULL）
          {
            builder.append（读）;
          }
       串JSONContents = builder.toString（）;
       reader.close（）;
       的JSONObject的JSONObject;
  尝试{
        JSONObject的=新的JSONObject（JSONContents）;
        字符串名称= jsonObject.getString（名称）;
        JSONObject的stateObject = jsonObject.getJSONObject（国家）;
        字符串stateValue = stateObject.getString（值）;
          如果（name.equals（目标））
           {
              HTT presponse响应=新BasicHtt presponse（HttpVersion.HTTP_1_1，200，OK）;
             response.setEntity（新StringEntity（国家是：+ stateValue））;
             conn.sendResponseHeader（响应）;
             conn.sendResponseEntity（响应）;
            }
           其他
           {
             HTT presponse响应=新BasicHtt presponse（HttpVersion.HTTP_1_1，404，未找到）;
             response.setEntity（新StringEntity（请求的资源+目标+不能因失配发现！））;
             conn.sendResponseHeader（响应）;
             conn.sendResponseEntity（响应）;
            }
        }赶上（JSONException E）{
          e.printStackTrace（）;
       }
  }
     其他
       {
           HTT presponse响应=新BasicHtt presponse（HttpVersion.HTTP_1_1，404，未找到）;
           response.setEntity（新StringEntity（请求的资源+目标+找不到！））;
           conn.sendResponseHeader（响应）;
           conn.sendResponseEntity（响应）;
       }
}
 

解决方案

链接的 http://www.integratingstuff.com/2011/10/24/adding-a-webserver-to-an-android-app/ 有一个很好的例子。我在code错过conn.close（）。

I m implementing a REST based HTTP server in Android. The server responds for GET, DELETE and POST requests. Two android devices communicate using HTTP Post (I m using a service, where a device keeps listening on a port and post to next device and this keeps going on).

I m testing the GET and DELETE using Mozilla Poster. Should I add a separate socket/port to handle the same? Because when I try now, sometimes I get timeout error or no response found. However, I am able to see server response in Logcat window. Please help me. Code to handle GET request:

if(method.equals("GET"))
 {
   if(checkFileExisting())
     {
       BufferedReader reader = new BufferedReader(new FileReader(new   File(getFilesDir()+File.separator+"script.json")));
       String read;
       StringBuilder builder = new StringBuilder("");
         while((read = reader.readLine()) != null)
          {
            builder.append(read);
          }
       String JSONContents = builder.toString();
       reader.close();
       JSONObject jsonObject;
  try {
        jsonObject = new JSONObject(JSONContents);
        String name = jsonObject.getString("name");
        JSONObject stateObject = jsonObject.getJSONObject("state");
        String stateValue = stateObject.getString("value"); 
          if(name.equals(target))
           {
              HttpResponse response = new BasicHttpResponse(HttpVersion.HTTP_1_1, 200, "OK");
             response.setEntity(new StringEntity("State is:" + stateValue));
             conn.sendResponseHeader(response);
             conn.sendResponseEntity(response);
            }
           else
           {                    
             HttpResponse response = new BasicHttpResponse(HttpVersion.HTTP_1_1, 404, "Not Found");
             response.setEntity(new StringEntity("The requested resource " + target + " could not be found due to mismatch!!"));
             conn.sendResponseHeader(response);
             conn.sendResponseEntity(response);
            }
        } catch (JSONException e) {
          e.printStackTrace();
       }
  }
     else
       {
           HttpResponse response = new BasicHttpResponse(HttpVersion.HTTP_1_1, 404, "Not Found");
           response.setEntity(new StringEntity("The requested resource " + target + " could not be found!!"));
           conn.sendResponseHeader(response);
           conn.sendResponseEntity(response);
       }                    
}   

解决方案

The link http://www.integratingstuff.com/2011/10/24/adding-a-webserver-to-an-android-app/ has a very good example. I missed conn.close() in my code.
