上传照片到自己的网站

Question

我一直在寻找一个程序来上传我用相机拍摄的照片，并存储在位图中到我自己的网站上。我尝试过跟随代码，但没有成功。

        public void onClick(View v) {
            ByteArrayOutputStream bytearrayStream = new ByteArrayOutputStream();
            bitmapPicture.compress(Bitmap.CompressFormat.JPEG, 90, bytearrayStream);
            byte [] byteArray = bytearrayStream.toByteArray();
            String byteArrayToString = Base64.encodeBytes(byteArray);
            ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
            nameValuePairs.add(new BasicNameValuePair("image", byteArrayToString));

            try{
                HttpClient httpclient = new DefaultHttpClient();
                HttpPost httppost = new HttpPost("http://www.mywebsite.com/upload_image.php");
                httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
                HttpResponse response = httpclient.execute(httppost);
                HttpEntity entity = response.getEntity();
                stream = entity.getContent();

                Toast text = Toast.makeText(getApplicationContext(), "OK", Toast.LENGTH_LONG);
                text.show();
            }
            catch(Exception e){
                Log.e("log_tag", "Error in http connection " + e.toString());
                Toast text = Toast.makeText(getApplicationContext(), "FOUT", Toast.LENGTH_LONG);
                text.show();

            }
        }

我在网站端使用的php代码是

<?php
$base=$_REQUEST['image'];
echo $base;
// base64 encoded utf-8 string
 $binary=base64_decode($base);
// binary, utf-8 bytes
header('Content-Type: bitmap; charset=utf-8');
// print($binary);
//$theFile = base64_decode($image_data);
$file = fopen('test.jpg', 'wb');
fwrite($file, $binary);
fclose($file);
echo '<img src=test.jpg />';
?>

如果我在本地主机上尝试php文件，它会生成一个test.jpg。所以我认为如果$_REQUEST['image']不是null，就会创建正确的文件。

如果try-area中没有错误，我的area程序会显示一个toasttext 'OK‘。如果有错误，它会显示'FOUT‘。在我的Xperia上测试时，总是显示OK...

有什么建议吗？

尝尝这个

public void executeMultipartPost() throws Exception {
try {
ByteArrayOutputStream bos = new ByteArrayOutputStream();
 bm.compress(CompressFormat.JPEG, 75, bos);
 byte[] data = bos.toByteArray();
 HttpClient httpClient = new DefaultHttpClient();
  HttpPost postRequest = new HttpPost("http://www.mywebsite.com/upload_image.phpamp");
 ByteArrayBody bab = new ByteArrayBody(data, "forest.jpg");

  MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
reqEntity.addPart("uploaded", bab);
 reqEntity.addPart("photoCaption", new StringBody("sfsdfsdf"));
 postRequest.setEntity(reqEntity);
HttpResponse response = httpClient.execute(postRequest);
 BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent(), "UTF-8"));
 String sResponse;
 StringBuilder s = new StringBuilder();

while ((sResponse = reader.readLine()) != null) {
 s = s.append(sResponse);
  }
 System.out.println("Response: " + s);
 } catch (Exception e) {
   // handle exception here
   Log.e(e.getClass().getName(), e.getMessage());
  }
 }
