Android使用php上传文件到服务器

Question

Hello am trying to upload a file from external storage of android phone to the url in the variable upLoadServerUri as below.

final String upLoadServerUri = "http://www.www.com/UploadToServer.php";
URL url = new URL(upLoadServerUri);

// Open a HTTP  connection to  the URL
conn = (HttpURLConnection) url.openConnection();
conn.setDoInput(true); // Allow Inputs
conn.setDoOutput(true); // Allow Outputs
conn.setUseCaches(false); // Don't use a Cached Copy
conn.setRequestMethod("POST");
conn.setRequestProperty("Connection", "Keep-Alive");
conn.setRequestProperty("ENCTYPE", "multipart/form-data");
conn.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary);
conn.setRequestProperty("uploaded_file", fileName);

dos = new DataOutputStream(conn.getOutputStream());

dos.writeBytes(twoHyphens + boundary + lineEnd);
dos.writeBytes("Content-Disposition: form-data; name=\"uploaded_file\";filename=\""
        + fileName + "\"" + lineEnd);

dos.writeBytes(lineEnd);

// create a buffer of  maximum size
bytesAvailable = fileInputStream.available();

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

// read file and write it into form...
bytesRead = fileInputStream.read(buffer, 0, bufferSize);

while (bytesRead > 0) {

    dos.write(buffer, 0, bufferSize);
    bytesAvailable = fileInputStream.available();
    bufferSize = Math.min(bytesAvailable, maxBufferSize);
    bytesRead = fileInputStream.read(buffer, 0, bufferSize);
    Log.d("Inside ByteRead", "Reading");
}

// send multipart form data necesssary after file data...
dos.writeBytes(lineEnd);
dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);

// Responses from the server (code and message)
serverResponseCode = conn.getResponseCode();
String serverResponseMessage = conn.getResponseMessage();


fileInputStream.close();
dos.flush();
dos.close();

The code below is being used in the UploadToServer.php file which is the destination url file in the java code above. I don't have knowledge on php end so can you advise me if below code would be able to store data when we trigger a file to it based on the java code above. Thanks.

<?php
// Where the file is going to be placed
$target_path = "recorded/";

/* Add the original filename to our target path.
Result is "uploads/filename.extension" */
$target_path = $target_path . basename( $_FILES['uploaded_file']['name']);

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