发送.txt文件，将文档文件发送到服务器android

我正在开发一个应用程序，其中我以字符串格式向服务器发送数据。以下是我的代码。它工作正常。但现在我的问题是如何将整个.txt文件和.doc文件发送到服务器。在我的GUI中，我必须提供用户选择的路径。意味着用户必须选择他/她想要发送文件的路径......请帮我解决我的问题...谢谢...发送.txt文件，将文档文件发送到服务器android

使用这个链接http://reecon.wordpress.com/2010/04/25/uploading-files-to-http-server-using-post-android-sdk/ –

@DixitPatel：谢谢...让我执行它... –

该代码上传数据（图片，MP3的，文本文件等）到HTTP服务器

HttpURLConnection connection = null; 
DataOutputStream outputStream = null; 
DataInputStream inputStream = null; 

String pathToOurFile = "/data/file_to_send.mp3"; 
String urlServer = "http://192.168.1.1/handle_upload.php"; 
String lineEnd = "\r\n"; 
String twoHyphens = "--"; 
String boundary = "*****"; 

int bytesRead, bytesAvailable, bufferSize; 
byte[] buffer; 
int maxBufferSize = 1*1024*1024; 

try 
{ 
FileInputStream fileInputStream = new FileInputStream(new File(pathToOurFile)); 

URL url = new URL(urlServer); 
connection = (HttpURLConnection) url.openConnection(); 

// Allow Inputs & Outputs 
connection.setDoInput(true); 
connection.setDoOutput(true); 
connection.setUseCaches(false); 

// Enable POST method 
connection.setRequestMethod("POST"); 

connection.setRequestProperty("Connection", "Keep-Alive"); 
connection.setRequestProperty("Content-Type", "multipart/formdata;boundary="+boundary); 

outputStream = new DataOutputStream(connection.getOutputStream()); 
outputStream.writeBytes(twoHyphens + boundary + lineEnd); 
outputStream.writeBytes("Content-Disposition: form-data; 
name=\"uploadedfile\";filename=\"" + pathToOurFile +"\"" + lineEnd); 
outputStream.writeBytes(lineEnd); 

bytesAvailable = fileInputStream.available(); 
bufferSize = Math.min(bytesAvailable, maxBufferSize); 
buffer = new byte[bufferSize]; 

// Read file 
bytesRead = fileInputStream.read(buffer, 0, bufferSize); 

while (bytesRead > 0) 
{ 
outputStream.write(buffer, 0, bufferSize); 
bytesAvailable = fileInputStream.available(); 
bufferSize = Math.min(bytesAvailable, maxBufferSize); 
bytesRead = fileInputStream.read(buffer, 0, bufferSize); 
} 

outputStream.writeBytes(lineEnd); 
outputStream.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd); 

// Responses from the server (code and message) 
serverResponseCode = connection.getResponseCode(); 
serverResponseMessage = connection.getResponseMessage(); 

fileInputStream.close(); 
outputStream.flush(); 
outputStream.close(); 
}

@Gaurav ...我如何设置IP和我必须发送文件的服务器的端口号...？ –

@ Anil Bhatiya在最初的行我给了字符串IP地址 – GOLDEE

@Gaurav ...雅这是好的。但没有端口号码，它会工作吗？是否有必要在http后面写入IP ...？ –

试试这个代码来创建txt文件写入字符串到文件并将其发送到服务器...

File f = new File(Environment.getExternalStorageDirectory(),"new"); 
     if(!f.exists()) 
     { 
      f.mkdir(); 
     } 
     File file = new File("new.txt"); 
     FileWriter w = new FileWriter("/sdcard/new/new.txt"); 
     BufferedWriter out = new BufferedWriter(w); 
     out.write(data); 
     out.flush(); 
     out.close(); 
          String file_name = "/sdcard/new/new.txt"; 

     File file1 = new File(file_name); 
     socket = new Socket("117.218.28.70", 2020); 

     ObjectInputStream ois = new ObjectInputStream(socket.getInputStream()); 
     ObjectOutputStream oos = new ObjectOutputStream(socket.getOutputStream()); 

     oos.writeObject(file1.getName()); 

     FileInputStream fis = new FileInputStream(file1); 
     byte [] buffer = new byte[450000]; 
     Integer bytesRead = 0; 

     while ((bytesRead = fis.read(buffer)) > 0) 
     { 
      oos.writeObject(bytesRead); 
      oos.writeObject(Arrays.copyOf(buffer, buffer.length)); 
     } 
     oos.close(); 
     ois.close(); 
     System.exit(0);
