推荐答案

我的最终工作Java和PHP code，从Android手机的SD卡上的文件上传到自己的Web服务器。

My final working JAVA and PHP code to upload a file from the Android's SD card to my own Web Server.

Java的/ Android的code：

private void doFileUpload() {

    HttpURLConnection conn = null;
    DataOutputStream dos = null;
    DataInputStream inStream = null;
    String existingFileName = Environment.getExternalStorageDirectory().getAbsolutePath() + "/mypic.png";
    String lineEnd = "\r\n";
    String twoHyphens = "--";
    String boundary = "*****";
    int bytesRead, bytesAvailable, bufferSize;
    byte[] buffer;
    int maxBufferSize = 1 * 1024 * 1024;
    String responseFromServer = "";
    String urlString = "http://mywebsite.com/directory/upload.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();
        // 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);
        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);

        }

        // 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();
        dos.flush();
        dos.close();

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

    //------------------ read the SERVER RESPONSE
    try {

        inStream = new DataInputStream(conn.getInputStream());
        String str;

        while ((str = inStream.readLine()) != null) {

            Log.e("Debug", "Server Response " + str);

        }

        inStream.close();

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

相关联的PHP code去你的服务器（upload.php的）上：

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

/* Add the original filename to our target path.  
Result is "uploads/filename.extension" */
$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";
    chmod ("uploads/".basename( $_FILES['uploadedfile']['name']), 0644);
} else{
    echo "There was an error uploading the file, please try again!";
    echo "filename: " .  basename( $_FILES['uploadedfile']['name']);
    echo "target_path: " .$target_path;
}
?>

需要注意的事项。
1）我有mypic.pngSD卡的根目录中。如，如果你看了，通过大容量存储设备的USB鉴于Android设备，你会在文件中你遇到的第一个目录。

Things to note.
1) I had "mypic.png" within the root directory of the SD card. As in, if you looked at the Android device through Mass Storage USB view you would put the file in the first directory you come across.

2）USB大容量存储必须关闭手机上的！或者只是完全从电脑你写在code，以确保这种情况下拔下电源插头。

2) USB MASS STORAGE MUST BE TURNED OFF ON THE PHONE! Or just completely unplug it from the computer you are writing the code on to assure this is the case.

3）我不得不在同一目录作为我的PHP文件中创建一个上传文件夹。

3) I had to create an "uploads" folder in the same directory as my php file.

4）你显然必须改变我写的 http://mywebsite.com/directory/upload.php <网址/ A>是你自己的网站。

4) You obviously must change the web address I have written as http://mywebsite.com/directory/upload.php to be your own website.
