php实现post请求 接收android客户端json数据 存储数据库 并返回json

大纲

实现php端存储数据库类

实现php端接收post请求

实现php端返回json数据

实现android 客户端 jsonbean

实现android 客户端 http请求线程类

Linux服务器检查mysql数据库 ，数据是否正常插入

php后台

-实现php端存储数据库类

<?php
class VideoClear{

/**
* 检验ID 并存储数据库 操作
*
* $id 客户端传来的 id
*
**/
public static function checkId($id){

//链接数据库
$con = mysql_connect("localhost","root","new-password");
//选择数据库
mysql_select_db("my_db",$con);
//检验Id是否存在
$result = mysql_query("select * from recordClear where recordId=".$id."");
$num = mysql_num_rows($result);
//获取星期
$time2 = date("N",time());

if($time2==2){//每周一开始清理

if($num){//数据存在 则 对次数增加
mysql_query("update recordClear set recordCount=recordCount+1 where recordId=".$id);//对数据自增
}else{//数据不存在 则建立新数据
$sql = "INSERT INTO recordClear(recordId,recordCount,cleardate) VALUES(".$id.",'1',".$time2.")";
$query = mysql_query($sql);
}
return "off".$id.mysql_error();
}else{
return "on";
}
mysql_close($con);

}

}
?>

-实现php端接收post请求

<?php
$json = file_get_contents("php://input");
$data = json_decode($json, true);
require_once('./Response1.php');

Response1::json($data['id']);
?>

-实现php端返回json数据

<?php
class Response1{
/**
*
*
*
* $codelangdao  朗道版本信息 返回的提示码
* $codezirui    子瑞版本信息 返回的提示码
* $message 返回的提示信息
* $data 返回的信息
*/
public static function json($id,$data){

require_once('./VideoClear.php');

$tag = 	VideoClear::checkId($id);

$result = array(
'clear_tag'=>"off",
'whether_clear'=>$tag,
);

echo json_encode($result,128);
exit;
}
}
?>

接下来是android客户端

-实现android 客户端 jsonbean

直接从php代码复制参数 保证书写不出错

/**
* Created by Administrator on 2016/6/14.
* author 王浩
* qq 1520777821
* 转载请注明
*/
public class VideoClearBean {

public String clear_tag;
public String whether_clear;

}

-实现android 客户端 http请求线程类

/**
* Created by Administrator on 2016/6/14.
* author 王浩
* qq 1520777821
* 转载请注明
*/
public class UpdataThread extends Thread implements Runnable {

public UpdataThread(){

}

@Override
public void run() {
super.run();
executeClear();

}

public void executeClear() {
InputStream inputStream = null;
HttpURLConnection urlConnection = null;
try {
URL url = new URL("http://191.101.237.106/test1.php");
urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
urlConnection.setRequestProperty("Accept", "application/json");
urlConnection.setRequestMethod("POST");
urlConnection.setDoOutput(true);
DataOutputStream wr = new DataOutputStream(urlConnection.getOutputStream());
//配置 json
Gson gson = new Gson();
RequestBean json = new RequestBean();
json.id = "15";
json.verName = "1.41";
String jsonString = gson.toJson(json);
Log.e("TAA", "TEST: 发出去的数据" + jsonString);

wr.writeBytes(jsonString);
wr.flush();
wr.close();
// try to get response
int statusCode = urlConnection.getResponseCode();
if (statusCode == 200) {
inputStream = new BufferedInputStream(urlConnection.getInputStream());

String str = VerUtils.inputStream2String(inputStream);

Log.e("TAA", "TEST:" + str);
VideoClearBean verBean = gson.fromJson(str, VideoClearBean.class);

Log.e("TAA", "TEST Bean::" + verBean.toString());

}
} catch (Exception e) {

} finally {
if (inputStream != null) {
try {
inputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
if (urlConnection != null) {
urlConnection.disconnect();
}
}
}

}

-Linux服务器检查mysql数据库 ，数据是否正常插入

我们用 id 15检测下 客户端运行代码

然后查询Linux查询mysql

+----------+-------------+------------+
9 rows in set (0.00 sec)

很明显我们成功了 15的数据已经插入进去了

假如测试时你的服务器爆出了这样的错误

重启服务器即可 这是mysql的bug

Warning: mysql_query(): Access denied for user 'root'@'localhost' (using password: NO) in /var/www/html/VideoClear.php on line 34

Warning: mysql_query(): A link to the server could not be established in /var/www/html/VideoClear.php on line 34

接下来再看下客户端的log
