Android并将文件上传到php服务器

Question

I'm writing an app which should send a file to PHP server. Here is my code:

    InputStream is = new FileInputStream(file);
    HttpClient httpClient = new DefaultHttpClient();
    HttpPost postRequest = new HttpPost("http://majkelsoftgames.cba.pl/ser/server.php");

    byte[] data = IOUtils.toByteArray(is);
    InputStreamBody isb= new InputStreamBody(new ByteArrayInputStream(data), "file");

    MultipartEntity multipartContent = new MultipartEntity();
    multipartContent.addPart("file", isb);

    postRequest.setEntity(multipartContent);
    HttpResponse response = httpClient.execute(postRequest);

My problem is that I really dont have experience in PHP and I dont know how to pick up this file on PHP side. I found some code:

<?php
    $target_path  = "./";
    $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!";
    }
?>

But it does not work. Can someone explain me how can I simply pick up fine on PHP side?

Answer 1

I think the issue is here:

InputStreamBody isb= new InputStreamBody(new ByteArrayInputStream(data), "file");

This is sending the data with the name "file", but then

$_FILES['uploadedfile']['name']

is trying to find a file named "uploadedfile". Make sure they match.

iF YOU WANT TO UPLOAD .pdf FILE TO LOCAL SERVER THEN USE THIS SIMPLE METHOD, Lets we are doing code here under Button Click Event...

if (isset($_POST['submit']))
{

if ( ($_FILES["file"]["type"] =="application/pdf"))
 { 

 if (file_exists("C:/xampplite/htdocs/site/upload/" . $_FILES["file"]["name"]))

    echo " This File is already exists in folder";

else
{
  move_uploaded_file ($_FILES["file"]["tmp_name"],"C:/xampplite/htdocs/site/upload/" . $_FILES["file"]["name"]);      
  echo "File have been Stored in:-C:/xampplite/htdocs/site/upload/ "  . $_FILES["file"]["name"];

  }
}

}//end of click_event
