Code to upload Video from Android to PHP

Question

I am trying to upload video from Android code to my PHP web server code but can't get success. I am referring the following link to perform the uploading task but I am getting the following response in my Android code, but can't found any file on PHP server.

Android response

DEBUG/ServerCode(29484): 200
DEBUG/serverResponseMessage(29484): OK

I have checked many things like setting values in php.ini files. Although I can upload images from Android code to server becasue from Android I am sending a 64 bit encoded ByteArray and therer is a ready-made function in php which can create image from encoded ByteArrays.

But that code also is not working in case of any other file having type other than image.

Please guide me if any of you have done something similar before.

PHP code I am using:

<?php

    $target_path  = "./upload/";

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

    if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path))
    {
        echo "The file ".basename( $_FILES['uploadedfile']['name'])." has been uploaded";
    } 
    else
    {
        echo "There was an error uploading the file, please try again!";
    }
?>

Android code I am using:

public void videoUpload()
{
    HttpURLConnection connection = null;
    DataOutputStream outputStream = null;
    DataInputStream inputStream = null;


    String pathToOurFile = "/sdcard/video-2010-03-07-15-40-57.3gp";
    String urlServer = "http://10.0.0.15/sampleWeb/handle_upload.php";
    String lineEnd = "\r\n";
    String twoHyphens = "--";
    String boundary =  "*****";

    int bytesRead, bytesAvailable, bufferSize;
    byte[] buffer;
    int maxBufferSize = 1*1024*1024;

    try
    {
    FileInputStream fileInputStream = new FileInputStream(new File(pathToOurFile) );

    URL url = new URL(urlServer);
    connection = (HttpURLConnection) url.openConnection();

    // Allow Inputs & Outputs
    connection.setDoInput(true);
    connection.setDoOutput(true);
    connection.setUseCaches(false);

    // Enable POST method
    connection.setRequestMethod("POST");

    connection.setRequestProperty("Connection", "Keep-Alive");
    connection.setRequestProperty("Content-Type", "multipart/form-data;boundary");

    outputStream = new DataOutputStream( connection.getOutputStream() );
    outputStream.writeBytes(twoHyphens + boundary + lineEnd);
    outputStream.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\"" + pathToOurFile );
    outputStream.writeBytes(lineEnd);

    bytesAvailable = fileInputStream.available();
    bufferSize = Math.min(bytesAvailable, maxBufferSize);
    buffer = new byte[bufferSize];

    // Read file
    bytesRead = fileInputStream.read(buffer, 0, bufferSize);

    while (bytesRead > 0)
    {
    outputStream.write(buffer, 0, bufferSize);
    bytesAvailable = fileInputStream.available();
    bufferSize = Math.min(bytesAvailable, maxBufferSize);
    bytesRead = fileInputStream.read(buffer, 0, bufferSize);
    }

    outputStream.writeBytes(lineEnd);
    outputStream.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);

    // Responses from the server (code and message)
    int serverResponseCode = connection.getResponseCode();
     String serverResponseMessage = connection.getResponseMessage();
     Log.d("ServerCode",""+serverResponseCode);
     Log.d("serverResponseMessage",""+serverResponseMessage);
    fileInputStream.close();
    outputStream.flush();
    outputStream.close();
    }
    catch (Exception ex)
    {
        ex.printStackTrace();
    }
}

Answer 1

My java is a bit ropey but....

It looks like connection.getResponseCode is returning only the HTTP status code, and connection.getResponseMessage is returning only the HTTP status message - but you're PHP does nothing to manipulate those values. You might try:

$target_path  = "./upload/";
$src = $_FILES['uploadedfile']['name'];

$target_path .= basename($src);

if(file_exists($src) 
        && 
        && move_uploaded_file($src, $target_path)
   ) {
    echo "The file ".basename( $_FILES['uploadedfile']['name'])." has been uploaded";
} else {
    header("Server Error", true, 503);
    echo "There was an error uploading the file, please try again!";
    $msg = "src size ? " 
       . filesize($src) . "\n dest dir writable ?"
       . is_writeable(dirname($target_path)) ? "Y\n" : "N\n"
       . "FILES contains :\n";
       . var_export($_FILES,true);
    // now write $msg somwhere you can read it
}

This shuld help in narrowing down what went wrong

private String mString;
private Uri image_uri;  
private String response;    
private HttpURLConnection conn = null;

//then call these two methods on button's onclick listener

mString = getRealPathFromURI(image_uri);

ImageUpload();

//write these methods here
