的Android + PHP：发送GET请求到PHP服务器 [英] Android + PHP: Sending a GET request to PHP server
问题描述
我试图发送从Android应用到Web服务器的GET请求，这样服务器将存储在数据库中的信息。
I'm trying to send a GET request from an Android app to a web server, so the server will store the information in a database.
下面是在 Android应用程序
public class Final extends Activity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_final);
Button btnSend = (Button)findViewById(R.id.BtnSend);
btnSend.setOnClickListener(new OnClickListener(){
public void onClick(View arg0){
TestReceiver();
}
});
void TestReceiver()
{
//ALERT MESSAGE
Toast.makeText(getBaseContext(),"Please wait, connecting to server.",Toast.LENGTH_LONG).show();
HttpClient Client = new DefaultHttpClient();
try
{
Client.getConnectionManager().getSchemeRegistry().register(getMockedScheme());
} catch (Exception e) {
System.out.println("Error con no se que");
}
String Value="Kevin";
String URL = "http://echogame24.comli.com/Receiver.php?action="+Value;
try
{
String SetServerString = "";
// Create Request to server and get response
HttpGet httpget = new HttpGet(URL);
ResponseHandler<String> responseHandler = new BasicResponseHandler();
SetServerString = Client.execute(httpget, responseHandler);
}
catch(Exception ex)
{
System.out.println("Fail!");
}
}
//** I added all this following the advise in the link below
public Scheme getMockedScheme() throws Exception {
MySSLSocketFactory mySSLSocketFactory = new MySSLSocketFactory();
return new Scheme("https", (SocketFactory) mySSLSocketFactory, 443);
}
class MySSLSocketFactory extends SSLSocketFactory {
javax.net.ssl.SSLSocketFactory socketFactory = null;
public MySSLSocketFactory(KeyStore truststore) throws Exception {
super(truststore);
socketFactory = getSSLSocketFactory();
}
public MySSLSocketFactory() throws Exception {
this(null);
}
@Override
public Socket createSocket(Socket socket, String host, int port, boolean autoClose) throws IOException,
UnknownHostException {
return socketFactory.createSocket(socket, host, port, autoClose);
}
@Override
public Socket createSocket() throws IOException {
return socketFactory.createSocket();
}
javax.net.ssl.SSLSocketFactory getSSLSocketFactory() throws Exception {
SSLContext sslContext = SSLContext.getInstance("TLS");
TrustManager tm = new X509TrustManager() {
public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
}
public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
}
public X509Certificate[] getAcceptedIssuers() {
return null;
}
};
sslContext.init(null, new TrustManager[] { tm }, null);
return sslContext.getSocketFactory();
}
}
}
在这个环节中接受的答案：
In the accepted answer of this link:
他们建议使用最后一个方法，使得应用程序可以发送请求的任何服务器。
They recommend to use the last methods so the application can send request to any server.
我还包括在 PHP服务器将接受请求的code：
I also include the code of the PHP server that will accept the request:
<?php
$name="A_".$_GET["action"] ;
require_once('mysql_conexion.php');
//Here we set the variables
$country = "Prueba";
$score = 200;
//Here we create the sql sentence we will need to insert information in the Data base
$q="INSERT INTO PLAYERS(NAME, COUNTRY, SCORE) VALUES ('$name', '$country', '$score')";
$r=@mysqli_query($dbc, $q);
//Now we check if we succed or failed
if($r){
//This means we did it right
echo 'There is a new player<br>';
}else{
//This means we failed
echo '<h1>Error </h1>
<p class="error">There was an error</p>';
echo '<p>'.mysqli_error($dbc).'<br /><br />Query:'.$q.'</p>';
}
//We close now the data base connection
mysqli_close($dbc);
?>
我的问题
包括了Android应用程序后，下面** 1，我有以下错误的方法：
After including in the Android Application the methods below **1 I have the following errors:
1 -
构造计划（字符串，Final.MySSLSocketFactory，INT）未定义
The constructor Scheme(String, Final.MySSLSocketFactory, int) is undefined
在该行：
return new Scheme("https", mySSLSocketFactory, 443);
2 -
在该行多个标记
- 类型Final.MySSLSocketFactory必须实现继承的抽象方法SocketFactory.createSocket（InetAddress类，INT，
InetAddress类，INT）
- 类型Final.MySSLSocketFactory必须实现继承的抽象方法SocketFactory.createSocket（字符串，整数）
- 类型Final.MySSLSocketFactory必须实现继承的抽象方法SSLSocketFactory.getSupportedCipherSuites（）
- 类型Final.MySSLSocketFactory必须实现继承的抽象方法SocketFactory.createSocket（InetAddress类，INT）
- 类型Final.MySSLSocketFactory必须实现继承的抽象方法SocketFactory.createSocket（字符串，INT，InetAddress类，
INT）
- 类型Final.MySSLSocketFactory必须实现继承的抽象方法SSLSocketFactory.getDefaultCipherSuites（）
Multiple markers at this line - The type Final.MySSLSocketFactory must implement the inherited abstract method SocketFactory.createSocket(InetAddress, int, InetAddress, int) - The type Final.MySSLSocketFactory must implement the inherited abstract method SocketFactory.createSocket(String, int) - The type Final.MySSLSocketFactory must implement the inherited abstract method SSLSocketFactory.getSupportedCipherSuites() - The type Final.MySSLSocketFactory must implement the inherited abstract method SocketFactory.createSocket(InetAddress, int) - The type Final.MySSLSocketFactory must implement the inherited abstract method SocketFactory.createSocket(String, int, InetAddress, int) - The type Final.MySSLSocketFactory must implement the inherited abstract method SSLSocketFactory.getDefaultCipherSuites()
在该行：
class MySSLSocketFactory extends SSLSocketFactory {
3 -
构造的SSLSocketFactory（密钥库）未定义
The constructor SSLSocketFactory(KeyStore) is undefined
在该行：
super(truststore);
谁能告诉我，我究竟做错了什么？我想我只是复制了code的那部分完全一样出现在这个问题的答案accpeted：
Could anyone tell me what am I doing wrong? I think I just copied that part of the code exactly like appear in the accpeted answer for the question:
推荐答案
您code可能是首先简化了，我建议你使用这个机器人库：
http://loopj.com/android-async-http/ ，让您尽样的HTTP请求。
Your code could be first of all simplified, i suggest you to use this android library: http://loopj.com/android-async-http/ which allows you to make every kind of HTTP requests.
在你下载了它，你应该很明显它导入到你的项目。
After you downloaded it you should obviously import it in your project.
code。与实施的Android异步HTTP客户端
Code with Android Asynchronous Http Client implemented
public class Final extends Activity {
AsyncHttpClient client = new AsyncHttpClient();
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_final);
Button btnSend = (Button)findViewById(R.id.BtnSend);
btnSend.setOnClickListener(new OnClickListener(){
public void onClick(View arg0){
TestReceiver();
}
});
void TestReceiver()
{
//ALERT MESSAGE
Toast.makeText(getBaseContext(),"Please wait, connecting to server.",Toast.LENGTH_LONG).show();
String Value="Kevin";
String url = "http://echogame24.comli.com/Receiver.php?action="+Value;
client.get(url, new AsyncHttpResponseHandler() {
@Override
public void onSuccess(String response) {
Toast.makeText(getBaseContext(),"Request made successfully.",Toast.LENGTH_LONG).show();
}
});
}
}
}
