Android並將文件上傳到php服務器

Question

我正在編寫一個應將文件發送到PHP服務器的應用程序。 這是我的代碼：

    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);

我的問題是我真的沒有PHP的經驗，我也不知道如何在PHP方面選擇此文件。 我找到了一些代碼：

<?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!";
    }
?>

但這行不通。 有人可以向我解釋一下如何在PHP方面輕松解決問題嗎？

Answer 1

我認為問題出在這里：

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

這將發送名稱為“文件”的數據，但是

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

正在嘗試查找名為“ uploadedfile”的文件。 確保它們匹配。

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
