Android file upload 檔案 上傳

將檔案上傳置後端server與php溝通
1.加入權限AndroidManifest.xml
<uses-sdk
        android:minSdkVersion="11"
        android:targetSdkVersion="21" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

2.加入三個檔案放在lib資料夾下
httpclient-4.3.6.jar
httpcore-4.3.3.jar
httpmime-4.3.6.jar

3./res/layout/main.xml

4.建立檔案AndroidMultiPartEntity.java

import java.io.FilterOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.nio.charset.Charset;

import org.apache.http.entity.mime.HttpMultipartMode;
import org.apache.http.entity.mime.MultipartEntity;

@SuppressWarnings("deprecation")
public class AndroidMultiPartEntity extends MultipartEntity

{

 private final ProgressListener listener;

 public AndroidMultiPartEntity(final ProgressListener listener) {
  super();
  this.listener = listener;
 }

 public AndroidMultiPartEntity(final HttpMultipartMode mode,
   final ProgressListener listener) {
  super(mode);
  this.listener = listener;
 }

 public AndroidMultiPartEntity(HttpMultipartMode mode, final String boundary,
   final Charset charset, final ProgressListener listener) {
  super(mode, boundary, charset);
  this.listener = listener;
 }

 @Override
 public void writeTo(final OutputStream outstream) throws IOException {
  super.writeTo(new CountingOutputStream(outstream, this.listener));
 }

 public static interface ProgressListener {
  void transferred(long num);
 }

 public static class CountingOutputStream extends FilterOutputStream {

  private final ProgressListener listener;
  private long transferred;

  public CountingOutputStream(final OutputStream out,
    final ProgressListener listener) {
   super(out);
   this.listener = listener;
   this.transferred = 0;
  }

  public void write(byte[] b, int off, int len) throws IOException {
   out.write(b, off, len);
   this.transferred += len;
   this.listener.transferred(this.transferred);
  }

  public void write(int b) throws IOException {
   out.write(b);
   this.transferred++;
   this.listener.transferred(this.transferred);
  }
 }
}

5.主檔Main.java

import java.io.File;
import java.io.IOException;

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.mime.content.FileBody;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.util.EntityUtils;

import tw.android.AndroidMultiPartEntity.ProgressListener;
import android.app.Activity;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.os.AsyncTask;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.ProgressBar;
import android.widget.TextView;

public class Main extends Activity {

 private ProgressBar progressBar;
 private String FILE_UPLOAD_URL,filePath = null;
 private TextView txtPercentage;
 private Button btnUpload;
 long totalSize = 0;
 
 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.main);

  txtPercentage = (TextView) findViewById(R.id.txtPercentage);
  btnUpload = (Button) findViewById(R.id.btnUpload);
  progressBar = (ProgressBar) findViewById(R.id.progressBar);

  /*上傳server網址*/
  FILE_UPLOAD_URL= "http://xxxxx.3eeweb.com/AndroidFileUpload/fileUpload.php";
  
  String folder="life"; //資料夾名稱
  String fileName="IMG_20150226_161243.jpg"; //要上傳的手機裡的檔案-檔案名稱
  
  filePath = "/storage/sdcard0/"+folder+"/"+fileName; // 檔案路徑位置
  
  /*上傳按鈕*/
  btnUpload.setOnClickListener(new View.OnClickListener() {

   public void onClick(View v) {
    // 上傳至後端sever
    new UploadFileToServer().execute();
   }
  });

 }

 /* 上傳至後端sever */
 private class UploadFileToServer extends AsyncTask {
  /* 背景執行前的顯示動作 */
  @Override
  protected void onPreExecute() {
   // 設定進度條初始為0
   progressBar.setProgress(0);
   super.onPreExecute();
  }

  /* 背景執行中的顯示動作 */
  @Override
  protected void onProgressUpdate(Integer... progress) {
   // 顯示進度條
   progressBar.setVisibility(View.VISIBLE);

   // 更新進度療
   progressBar.setProgress(progress[0]);

   // 更新顯示文字百分比
   txtPercentage.setText(String.valueOf(progress[0]) + "%");
  }

  /* 背景執行的工作 */
  @Override
  protected String doInBackground(Void... params) {
   return uploadFile();
  }

  @SuppressWarnings("deprecation")
  private String uploadFile() {
   String responseString = null;

   HttpClient httpclient = new DefaultHttpClient();
   HttpPost httppost = new HttpPost(FILE_UPLOAD_URL);

   try {
    AndroidMultiPartEntity entity = new AndroidMultiPartEntity(
      new ProgressListener() {

       public void transferred(long num) {
        publishProgress((int) ((num / (float) totalSize) * 100));
       }
      });

    File sourceFile = new File(filePath);

    
    // Adding file data to http body
    entity.addPart("image", new FileBody(sourceFile));
    /* 攜帶參數(非必要) */
    // Extra parameters if you want to pass to server
//    entity.addPart("website",
//      new StringBody("www.androidhive.info"));
//    entity.addPart("email", new StringBody("abc@gmail.com"));

    totalSize = entity.getContentLength();
    httppost.setEntity(entity);

    // Making server call
    HttpResponse response = httpclient.execute(httppost);
    HttpEntity r_entity = response.getEntity();

    int statusCode = response.getStatusLine().getStatusCode();
    if (statusCode == 200) {
     // Server response
     responseString = EntityUtils.toString(r_entity);
    } else {
     responseString = "Error occurred! Http Status Code: "
       + statusCode;
    }

   } catch (ClientProtocolException e) {
    responseString = e.toString();
   } catch (IOException e) {
    responseString = e.toString();
   }

   return responseString;

  }

  /* 背景執行完成後的顯示動作 */
  @Override
  protected void onPostExecute(String result) {
   Log.e("END", "Response from server: " + result);

   /* 完成後alert顯示訊息 */
   showAlert(result);

   super.onPostExecute(result);
  }

 }

 /* 完成後alert顯示訊息 */
 private void showAlert(String message) {
  AlertDialog.Builder builder = new AlertDialog.Builder(this);
  builder.setMessage(message).setTitle("Response from Servers")
    .setCancelable(false)
    .setPositiveButton("OK", new DialogInterface.OnClickListener() {
     public void onClick(DialogInterface dialog, int id) {
      // do nothing
     }
    });
  AlertDialog alert = builder.create();
  alert.show();
 }

}

6.後端php接收檔案/AndroidFileUpload/fileUpload.php
檔案會上傳至/AndroidFileUpload/uploads/

echo $_FILES['image']['name'] . '< br/>';


//ini_set('upload_max_filesize', '10M');
//ini_set('post_max_size', '10M');
//ini_set('max_input_time', 300);
//ini_set('max_execution_time', 300);


$target_path = "uploads/";

$target_path = $target_path . basename($_FILES['image']['name']);

try {
    //throw exception if can't move the file
    if (!move_uploaded_file($_FILES['image']['tmp_name'], $target_path)) {
        throw new Exception('Could not move file');
    }

    echo "The file " . basename($_FILES['image']['name']) .
    " has been uploaded";
} catch (Exception $e) {
    die('File did not upload: ' . $e->getMessage());
}
