Question

我已经创建了一个带有自定义类的绘图应用程序，我将该类命名为＆＃34; drawView＆＃34;。在有人完成绘制之后，他点击了一个名为＆＃34; saveBtn＆＃34;的按钮，然后它应该使用php将图像上传到服务器。

请查看下面的代码并帮我弄清楚为什么它不上传图片。

CreateSingleSignature.java： （我只是告诉你主要代码..没有onCreate等。）

public class CreateSigleSignature extends Activity implements OnClickListener{
    private MainDrawingView drawView;
    Button saveBtn;
    InputStream inputStream;
    Bitmap bm;

public void onClick(View v) {
    switch (v.getId()) {
        case R.id.save_btn:
              try {
                    drawView.setDrawingCacheEnabled(true);
                    bm = Bitmap.createBitmap(drawView.getDrawingCache());
                    executeMultipartPost();
              } catch (Exception e) {
                  Log.e(e.getClass().getName(), e.getMessage());
              }
              drawView.destroyDrawingCache();
        break;
    }
}

public void executeMultipartPost() throws Exception {
    try {
        ByteArrayOutputStream bos = new ByteArrayOutputStream();
        bm.compress(Bitmap.CompressFormat.JPEG, 100, bos);
        byte[] data = bos.toByteArray();
        HttpClient httpClient = new DefaultHttpClient();
        HttpPost postRequest = new HttpPost(
                "http://www.zinman.byethost6.com/up/upload.php");
        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();
        sResponse = reader.readLine();
        AlertDialog alertDialog = new AlertDialog.Builder(this).create();
        alertDialog.setTitle("Upload Information");
        alertDialog.setMessage(sResponse);
        alertDialog.setButton("OK", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int which) {

            }
        });
        alertDialog.show();
    } catch (Exception e) {
        // handle exception here
        Log.e(e.getClass().getName(), e.getMessage());
    }
}

upload.php的：

 if(isset($_FILES['uploaded'])){
    move_uploaded_file($_FILES['uploaded']['tmp_name'], "bvbvb.jpg");
    echo $_FILES['uploaded']['tmp_name'] . "  ";
    echo $_FILES['uploaded']['name'] . "  ";
    echo $_FILES['uploaded']['type'] . "  ";
    echo $_FILES['uploaded']['size'];

    $data = file_get_contents($_FILES['uploaded']['tmp_name']);
    echo $data;
        $image = imagecreatefromstring( $data );
    move_uploaded_file($image, "bb.jpg");
    echo $image;
}

正如你所看到的，我创建了两个用php上传文件但没有任何工作的选项。如何解决？
