Question

我有一个Android应用程序将数据发布到php webservice，如果它从Android应用程序发布到php webserive它不能按预期工作，如果相同的数据从HTML页面发布到php webservice它工作正常。

php脚本中不起作用的部分如下：

function makeThumb($src, $dest, $desired_width) {

/* read the source image */ 
$imgsrc =   explode('.',$src,-1);
$imgdest    =   explode('.',$dest,-1);
$dest   =   $imgdest[0].'Thumb.png';
$source_image = imageConvert($src, $dest,0);



list($width, $height, $img_type, $img_attr) = getimagesize($dest);

//$width = imagesx($source_image);
//$height = imagesy($source_image);

/* find the "desired height" of this thumbnail, relative to the desired width  */
$desired_height = floor($height * ($desired_width / $width));

/* create a new, "virtual" image */

$virtual_image = imagecreatetruecolor($desired_width, $desired_height);

imagealphablending($virtual_image, false);
/* copy source image at a resized size */
$source_image = imagecreatefrompng($source_image);
//imagealphablending($source_image, false);

imagecopyresampled($virtual_image, $source_image, 0, 0, 0, 0, $desired_width, $desired_height, $width, $height);

/* create the physical thumbnail image to its destination */
imagealphablending($virtual_image,false);
imagesavealpha($virtual_image,true);
imagepng($virtual_image, $dest);

}

从android发布到php文件的代码是：

protected void onActivityResult(int requestCode, int resultCode,
        Intent imageReturnedIntent) {
    super.onActivityResult(requestCode, resultCode, imageReturnedIntent);

    // ::

    File tempFile = getTempFile();

    String filePath = Environment.getExternalStorageDirectory() + "/"
            + TEMP_PHOTO_FILE;
    System.out.println("path " + filePath);

    Bitmap bitmap = BitmapFactory.decodeFile(filePath);

    // Bitmap bitmap = BitmapFactory.decodeFile(picturePath);
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    bitmap.compress(Bitmap.CompressFormat.PNG, 90, stream); // compress to
                                                            // which format
                                                            // you want.
    byte[] byte_arr = stream.toByteArray();
    String image_str = Base64.encodeBytes(byte_arr);
    final ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();

    //nameValuePairs.add(new BasicNameValuePair("action", "uploadImage"));
    nameValuePairs.add(new BasicNameValuePair("image", image_str));
    nameValuePairs.add(new BasicNameValuePair("sociochatU",
            IMService.USERNAME));
    nameValuePairs.add(new BasicNameValuePair("sociochatP",
            IMService.password));
    nameValuePairs.add(new BasicNameValuePair("mpf",
            "true"));

    Thread t = new Thread(new Runnable() {
        @Override
        public void run() {
            try {
                HttpClient httpclient = new DefaultHttpClient();
                HttpPost httppost = new HttpPost(
                        SocketOperator.AUTHENTICATION_SERVER + "includes/inc.upload.php");
                httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
                HttpResponse response = httpclient.execute(httppost);
                final String the_string_response = convertResponseToString(response);
                runOnUiThread(new Runnable() {

                    @Override
                    public void run() {
                        Toast.makeText(UserProfile.this,
                                "Response " + the_string_response,
                                Toast.LENGTH_LONG).show();
                    }
                });

            } catch (final Exception e) {

                System.out.println("Error in http connection "
                        + e.toString());
            }
        }

    });

    t.start();

}

我在HTML中用来发布到同一个php文件的代码是followig：

<form method="POST" action="SocketOperator.AUTHENTICATION_SERVER & "includes/inc.upload.php" target="_blank">

<input name="sociochatU" id="sociochatU" value=""/><br/>
    <input name="sociochatP" id="sociochatP" value=""/><br/>
    <input name="mpf" id="mpf" value="true"/><br/>
<textarea name="image" id="base64"></textarea><br/>
<input type="submit" name="Submit" id="Submit" value="Submit"/><br/>

我不知道问题是什么，有什么建议吗？

在此处发布代码后立即发现问题。

我注意到android应用程序正在将图像压缩为PNG图像，并且在服务器端它将其指定为JPG文件，更改了php文件上的代码，而不是分配PNG扩展名和瞧。有效。
