現在、私はWebサービス用のアプリバージョンの構築に取り組んでいるため、Androidフォン内からアプリを介してcakephp Webサーバーに画像をアップロードしようとしています。

//アンドロイドコード

HttpURLConnection conn = null;
        DataOutputStream dos = null;
        DataInputStream inStream = null;
        String existingFileName = Environment.getExternalStorageDirectory().getAbsolutePath() + "/New Folder/rsz_passportphoto.jpg";
        String lineEnd = "\r\n";
        String twoHyphens = "--";
        String boundary =  "*****";
        int bytesRead, bytesAvailable, bufferSize;
        byte[] buffer;
        int maxBufferSize = 1*1024*1024;
        String responseFromServer = "";
        String urlString = "http://msm.icas.edu.sg/FANS/FANSweb/app/controllers/pagesext_controller.php";
        try
        {
         //------------------ CLIENT REQUEST
        FileInputStream fileInputStream = new FileInputStream(new File(existingFileName) );
         // open a URL connection to the Servlet
         URL url = new URL(urlString);
         // Open a HTTP connection to the URL
         conn = (HttpURLConnection) url.openConnection();
         System.out.println("Connected");
         // Allow Inputs
         conn.setDoInput(true);
         // Allow Outputs
         conn.setDoOutput(true);
         // Don't use a cached copy.
         conn.setUseCaches(false);
         // Use a post method.
         conn.setRequestMethod("POST");
         conn.setRequestProperty("Connection", "Keep-Alive");
         conn.setRequestProperty("Content-Type", "multipart/form-data;boundary="+boundary);
         dos = new DataOutputStream( conn.getOutputStream() );
         dos.writeBytes(twoHyphens + boundary + lineEnd);
         dos.writeBytes("Content-Disposition: form-data; name=\"uploadedfile\";filename=\"" + existingFileName + "\"" + lineEnd);

         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);
         }
         // send multipart form data necesssary after file data...
         dos.writeBytes(lineEnd);
         dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);
         // close streams
         Log.e("Debug","File is written");
         fileInputStream.close();

詳細: http://getablogger.blogspot.com/2008/01/android-how-to-post-file-to-php-server.html#ixzz21qi0MF72

またはこれを試してください

//phpコード

<?php

$target_path = "uploads/";

$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!";
}

?>

///アンドロイドコードはここに入る

import java.io.BufferedInputStream;

}


void doStart(FileInputStream stream){
fileInputStream = stream;

}

FileInputStream fileInputStream = null;
void thirdTry(){
String exsistingFileName = "asdf.png";

String lineEnd = "\r\n";
String twoHyphens = "--";
String boundary = "*****";
String Tag="3rd";
try
{
//------------------ CLIENT REQUEST

Log.e(Tag,"Starting to bad things");

Log.e(Tag,"Headers are written");

int ch;

StringBuffer b =new StringBuffer();

dos.close();


}
catch (MalformedURLException ex)
{
Log.e(Tag, "error: " + ex.getMessage(), ex);
}

catch (IOException ioe)
{
Log.e(Tag, "error: " + ioe.getMessage(), ioe);
}
}

}

Many of the headers included in the above file is not required, i was trying and failing :).

Now to upload file here is the java code from my activity class


public void uploadFile(){


try {
FileInputStream fis =this.openFileInput(NAME_OF_FILE);
HttpFileUploader htfu = new HttpFileUploader("http://11.0.6.23/test2.php","noparamshere", NAME_OF_FILE);
htfu.doStart(fis);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
