这是我的android代码，它正常执行我调试它并说发送数据。
public void postRegistrationData(final String result) {
// Create a new HttpClient and Post Header
Thread thread = new Thread(new Runnable(){
@Override
public void run() {
try {
try {
URL url;
HttpURLConnection urlConn;
url = new URL ("http://192.168.*.**/server/mypage.php");
urlConn = (HttpURLConnection)url.openConnection();
urlConn.setDoInput (true);
urlConn.setDoOutput (true);
urlConn.setUseCaches (false);
urlConn.setRequestProperty("Content-Type","application/json");
urlConn.setRequestProperty("Accept", "application/json");
urlConn.setRequestMethod("POST");
urlConn.connect();
//Create JSONObject here
JSONObject jsonParam = new JSONObject();
jsonParam.put(result, true);
// Send POST output.
/*printout = new DataOutputStream(urlConn.getOutputStream ());
printout.writeUTF(URLEncoder.encode(jsonParam.toString(),"UTF-8"));
Log.i("NOTIFICATION", "Data Sent");
printout.flush ();
printout.close ();*/
OutputStreamWriter os = new OutputStreamWriter(urlConn.getOutputStream(), "UTF-8");
os.write(jsonParam.toString());
Log.i("NOTIFICATION", "Data Sent");
os.close();
} catch (MalformedURLException muex) {
// TODO Auto-generated catch block

ioex.printStackTrace();

});
thread.start();
}
这是服务器（XAMPP）端PHP代码，它在我运行时正确插入数据，但不是来自我手机上的Android应用程序。我在本网站和其他网站上阅读了所有相似的回复，但他们的解决方案在过去的两天里对我没有用，并决定看看是否有人可以帮助我。非常需要和赞赏你的帮助。
<?php
header('Content-type: application/json');
// connect to the database
$servername = "localhost";
$username = "root";
$password = "password";
$dbname = "db";
$received = json_decode(stripslashes($_POST['json']));
// if text data was posted
if(isset($received['result'])){
//print_r($_POST);
try {
$conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
// set the PDO error mode to exception
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
//$data = urldecode($_POST['regid']);
$sql = "INSERT INTO table (regID) VALUES ('$received')";
// use exec() because no results are returned
$conn->exec($sql);
echo "New record created successfully";
} catch (PDOException $e) {
echo $sql . "<br>" . $e->getMessage();
}
$conn = null;
}elseif ($received === NULL) {
echo "Not value passed!!!!!!!!!!!!";
}
?>
这是logcat日志。

答案 0 :(得分：2)
这可能是您在代码中的问题 jsonParam.put（result，true）; 。
您输入结果参数作为键，布尔值作为值，这意味着每当您的键值不同时，您必须在设置时发送密钥你的PHP代码。
我希望它可能对你有用。
答案 1 :(得分：0)
看起来你错过了帖子数据的KeyName。试试这个
.....
String postData="json="+jsonParam.toString();
.....
os.write(postData);
...
