在這裏,我將提供一個完整的PHP和Android應用程序從Android應用程序將數據發送到服務器。
假設你在你的數據庫有此表:
------------------------
| movie_id | movie_name|
------------------------
1 PHP腳本
<?php
$servername="localhost";
$username="root";
$password="";
$db="derar";
$connection=mysqli_connect($servername,$username,$password,$db);
$json = file_get_contents('php://input');
$obj = json_decode($json,true);
$movie_name=$obj['movie_name'];
mysqli_query($connection,"insert into movie (movie_id, movie_name) VALUES (NULL,'$movie_name');");
echo "inserted";
?>
這個代碼是簡單的代碼,你必須把SQL注入。
2- Android應用程序
activity_main。XML
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.example.win7.derar.MainActivity">
<Button
android:id="@+id/send_button"
android:layout_width="match_parent"
android:text="إضغط لإرسال المعلومات"
android:layout_height="wrap_content" />
</RelativeLayout>
MainActivity
public class MainActivity extends AppCompatActivity {
private Button send_button;
private String Server_URL="http://192.168.1.101/derar/insertDataToServer.php";
private String movie_name="Titanic";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
send_button=(Button)findViewById(R.id.send_button);// Button Assignment
send_button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
SendDataToServer sendDataToServer=new SendDataToServer();
sendDataToServer.execute(Server_URL,movie_name);
}
});// Button On Click Listener
}
private class SendDataToServer extends AsyncTask<String, Void, Boolean> {
@Override
protected Boolean doInBackground(String... urls) {
OutputStream os = null;
InputStream is = null;
HttpURLConnection conn = null;
try {
URL url = new URL(urls[0]);
JSONObject jsonObject = new JSONObject();
jsonObject.put("movie_name", urls[1]);
String message = jsonObject.toString();
Log.d(message, "Test");
conn = (HttpURLConnection) url.openConnection();
conn.setReadTimeout(10000);
conn.setConnectTimeout(15000);
conn.setRequestMethod("POST");
conn.setDoInput(true);
conn.setDoOutput(true);
conn.setFixedLengthStreamingMode(message.getBytes().length);
conn.setRequestProperty("Content-Type", "application/json; charset=utf-8");
conn.setRequestProperty("X-Requested-With", "XMLHttpRequest");
conn.connect();
os = new BufferedOutputStream(conn.getOutputStream());
os.write(message.getBytes());
os.flush();
is = conn.getInputStream();
} catch (MalformedURLException e) {
Toast.makeText(getApplicationContext(), e.toString(), Toast.LENGTH_LONG).show();
;
e.printStackTrace();
return false;
} catch (IOException e) {
Toast.makeText(getApplicationContext(), e.toString(), Toast.LENGTH_LONG).show();
;
e.printStackTrace();
return false;
} catch (JSONException e) {
e.printStackTrace();
} finally {
try {
assert os != null;
os.close();
assert is != null;
is.close();
} catch (IOException e) {
e.printStackTrace();
}
conn.disconnect();
}
return true;
}
@Override
protected void onPostExecute(Boolean result) {
if (result) {
Toast.makeText(getApplicationContext(), "لقد نجح إرسال المعلومات", Toast.LENGTH_LONG).show();
} else {
Toast.makeText(getApplicationContext(), "فشل في إرسال المعلومات", Toast.LENGTH_LONG).show();
}
}
}
}
而且不要忘記這樣做:
1添加此權限清單文件:
<uses-permission android:name="android.permission.INTERNET" />
2-更改來自的IP地址
到您自己的IP地址,以運行本地主機服務器。
我希望這對你有用。
對我來說postman的回報總是正確的......無論是在POST和GET。 – RaV
用$ obj - > username替換$ obj [「username」]並重試。 –
@RaV,真的嗎?我只選擇POST類型,並添加網址,並返回404錯誤-_-'相同:gclimb.com/androidphp/index.php?username=Myname(POST類型) – Cofeina
