本文实例为大家分享了Android九宫格图片展示的具体代码，供大家参考，具体内容如下
首先时node.js服务器端代码
var http = require("http"); var fs = require("fs"); var queryString = require('querystring'); var url = require('url'); var util = require('util'); http.createServer(function (request, response) { // 定义了一个post变量，用于暂存请求体的信息 var post = ''; request.on('data', function(chunk){ post += chunk; }); // 在end事件触发后，通过querystring.parse将post解析为真正的POST请求格式，然后向客户端返回。 request.on('end', function(){ post = queryString.parse(post); console.log("请求结束"+post.body); response.writeHead(200, {"Content-Type": "text/plain;charset=utf8"}); response.write("请求成功"); response.end(); }); }).listen(8888); console.log("服务器启动"); function writeFile(str) { fs.writeFile('E:/log.txt', str, function (err) { if (err) { return console.error(err); } console.log("数据写入成功！"); }) }
然后是Android部分
package com.example.hanbo.servertest; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.TextView; import org.json.JSONObject; import java.io.BufferedReader; import java.io.BufferedWriter; import java.io.IOException; import java.io.InputStream; import java.io.InputStreamReader; import java.io.OutputStream; import java.io.OutputStreamWriter; import java.io.UnsupportedEncodingException; import java.net.HttpURLConnection; import java.net.MalformedURLException; import java.net.ProtocolException; import java.net.URL; import java.net.URLEncoder; public class MainActivity extends AppCompatActivity { private TextView textView; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); textView= (TextView) findViewById(R.id.textView); Button button= (Button) findViewById(R.id.button); button.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { textView.setText("开始请求"); new Thread(new Runnable() { @Override public void run() { HttpURLConnection connection = null; URL url = null; try { url = new URL("http://192.168.1.177:8888"); connection = (HttpURLConnection) url.openConnection(); connection.setRequestMethod("POST"); connection.setConnectTimeout(8000); connection.setReadTimeout(8000); connection.setRequestProperty("Content-Type","application/json"); OutputStream outputStream=connection.getOutputStream(); BufferedWriter requestBody=new BufferedWriter(new OutputStreamWriter(outputStream)); String str = URLEncoder.encode("抓哇", "UTF-8"); requestBody.write("name=javaPost&body=1"); requestBody.flush(); requestBody.close(); getResponseJava(connection); } catch (MalformedURLException e) { e.printStackTrace(); } catch (ProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } } }).start(); } }); } private void getResponseJava(HttpURLConnection urlConnection) { InputStream in = null; try { in = urlConnection.getInputStream();//响应 } catch (IOException e) { urlConnection.disconnect(); //textView.setText(e.getMessage()); return; } BufferedReader reader = null; try { reader = new BufferedReader(new InputStreamReader(in,"UTF-8")); } catch (UnsupportedEncodingException e1) { e1.printStackTrace(); } final StringBuilder result = new StringBuilder(); String tmp = null; try { while((tmp = reader.readLine()) != null){ result.append(tmp); } } catch (IOException e) { //textView.setText(e.getMessage()); return; } finally { try { reader.close(); urlConnection.disconnect(); } catch (IOException e) { } } runOnUiThread(new Runnable() { @Override public void run() { textView.setText(result); } }); } }
