استفاده از HTTPURLConnection در اندروید

به نام خدا

سلام.

یکی از تغییرات به گفته #گوگل در اندروید #مارشمالو حذف Apache HTTP client می باشد.
و گوگل پیشنهاد کرده به جای آن ، برنامه نویسان از #HttpURLConnection استفاده کنند. حال ما میخوایم یه مثال کامل و با توضیحات از این متد براتون قرار بدیم:

//import these on your header
import java.io.IOException;
import java.io.PrintWriter;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.ProtocolException;
import java.net.URL;
import java.net.URLEncoder;
import java.util.Scanner;

//do this wherever you are wanting to POST
URL url;
HttpURLConnection conn;

try{
//if you are using https, make sure to import java.net.HttpsURLConnection
url=new URL(“http://esfandune.ir/somefile.php”);

//you need to encode ONLY the values of the parameters
String param=”param1=” + URLEncoder.encode(“value1″,”UTF-8″)+
“&param2=”+URLEncoder.encode(“value2″,”UTF-8″)+
“&param3=”+URLEncoder.encode(“value3″,”UTF-8″);

conn=(HttpURLConnection)url.openConnection();
//set the output to true, indicating you are outputting(uploading) POST data
conn.setDoOutput(true);
//once you set the output to true, you don’t really need to set the request method to post, but I’m doing it anyway
conn.setRequestMethod(“POST”);

//Android documentation suggested that you set the length of the data you are sending to the server, BUT
// do NOT specify this length in the header by using conn.setRequestProperty(“Content-Length”, length);
//use this instead.
conn.setFixedLengthStreamingMode(param.getBytes().length);
conn.setRequestProperty(“Content-Type”, “application/x-www-form-urlencoded”);
//send the POST out
PrintWriter out = new PrintWriter(conn.getOutputStream());
out.print(param);
out.close();

//build the string to store the response text from the server
String response= “”;

//start listening to the stream
Scanner inStream = new Scanner(conn.getInputStream());

//process the stream and store it in StringBuilder
while(inStream.hasNextLine())
response+=(inStream.nextLine());

}
//catch some error
catch(MalformedURLException ex){
Toast.makeText(MyActivity.this, ex.toString(), 1 ).show();

}
// and some more
catch(IOException ex){

Toast.makeText(MyActivity.this, ex.toString(), 1 ).show();
}

امیدواریم بتونه کمکتون کنه.
همیشه از متدهای جدید استفاده کنید:)
