在Android中处理HttpURLConnection的java服务器端代码

1 周，5 日 Questions & Answers 1064

我正在使用HttpURLConnection类将文本文件上载到Apache服务器。对于服务器端代码，我使用php处理POST请求。我想知道，除了PHP，如何做同样的事情，或者PHP是处理服务器端文件上传的最佳方式？。。此外，我在服务器端找不到任何jsp或java代码来处理http post请求。。除了PHP之外，任何做同样事情的代码片段都会非常有用。。因为我认为java或jsp更容易编码。。谢谢

要上载文件的Android代码：

  public void upLoad()
{


     String exsistingFileName = path+"//"+"test.txt";

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

         Log.e(Tag, "Inside second Method");

         FileInputStream fileInputStream = new FileInputStream(new File(
                 exsistingFileName));

         // 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);


         DataOutputStream dos = new DataOutputStream(conn.getOutputStream());

         dos.writeBytes(twoHyphens + boundary + lineEnd);
         dos.writeBytes("Content-Disposition: post-data; name=uploadedfile;filename="
                         + exsistingFileName + "" + lineEnd);
         dos.writeBytes(lineEnd);

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

         // create a buffer of maximum size

         int bytesAvailable = fileInputStream.available();
         int maxBufferSize = 1000;
         // int bufferSize = Math.min(bytesAvailable, maxBufferSize);
         byte[] buffer = new byte[bytesAvailable];

         // read file and write it into form...

         int bytesRead = fileInputStream.read(buffer, 0, bytesAvailable);

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

         // send multipart form data necesssary after file data...

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

         // close streams
         Log.e(Tag, "File is written");
         fileInputStream.close();
         dos.flush();
         dos.close();

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

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

     try {
         BufferedReader rd = new BufferedReader(new InputStreamReader(conn
                 .getInputStream()));
         String line;
         while ((line = rd.readLine()) != null) {
             Log.e("Dialoge Box", "Message: " + line);
         }
         rd.close();

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

服务器端的Php代码：

 <?php
 $target_path  = "./upload/";
 $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!";
 }
?>

有 Java 编程相关的问题?
