java - 无法在服务器上查看上传的图像

Question

当我尝试在服务器上上传图像时，它在我的设备上显示“图像上传成功”，但我无法在服务器上看到该图像。
我什至尝试通过将图像转换为 Base64 来上传图像。

这是我的代码。

            try {
                HttpClient httpclient = new DefaultHttpClient();
                HttpPost httppost = new HttpPost(url);
                httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
                HttpResponse response = httpclient.execute(httppost);
                String responseStr = EntityUtils.toString(response.getEntity());
                Log.i(TAG, "doFileUpload Response : " + responseStr);
                handler.sendEmptyMessage(1);
            } catch (Exception e) {
                System.out.println("Error in http connection " + e.toString());
                handler.sendEmptyMessage(0);
            }
        }
    });
    t.start();

}

public String convertBitmapToString(Bitmap bmp){
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    bmp.compress(Bitmap.CompressFormat.JPEG, 90, stream); //compress to which format you want.
    byte[] byte_arr = stream.toByteArray();
    String imageStr = Base64.encodeToString(byte_arr, Base64.DEFAULT);
    return imageStr;
}

但是在运行时它显示错误:

E/Surface: getSlotFromBufferLocked: unknown buffer: 0x7f9e668360

请尝试此代码将图像上传到服务器......!我希望它对你有帮助......!
