我想将.mp3文件(仅)从设备上传到我的服务器.

我想浏览媒体数据的路径并选择任何mp3文件并上传.

我怎样才能做到这一点？

解决方法:

我的最终工作JAVA和PHP代码,用于将Android的SD卡上传文件到我自己的Web服务器.

Java / AndroID代码：

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);    }}

要在服务器上运行的相关PHP代码(upload.PHP)：

<?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;}?>

注意事项.
1)我在SD卡的根目录中有“mypic.png”.如果您通过Mass Storage USB视图查看AndroID设备,则会将该文件放在您遇到的第一个目录中.

2)必须在手机上关闭USB大容量存储！或者只是从正在编写代码的计算机上完全拔掉它,以确保是这种情况.

3)我必须在与我的PHP文件相同的目录中创建一个“uploads”文件夹.

4)您显然必须将我写为http://mywebsite.com/directory/upload.php的网址更改为您自己的网站.
