将图片从Android上传到PHP服务器（安卓导入图片）

我正在尝试从Android设备将文件上传到php服务器。有相同问题的话题，但他使用的是不同的方法。我的Android辅助代码运行正常，并且未显示任何错误消息，但服务器未收到任何文件。这是我的示例代码，我在网上找到了。

     }    }    }

和我的PHP服务器端代码如下

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

Apache正在运行。当我运行服务器时，出现此错误消息。上传文件时出错，请重试！我已经在eclipse中检查了日志数据，我认为是套接字问题，但是我不确定。如果有人知道解决方案，请提供帮助。

小编典典

似乎服务器没有响应客户端。尝试通过Android应用程序使用ftp连接进行上传，如果可以的话，请检查您的Apache配置是否接受连接和可写目录。当我遇到类似的问题时，事实证明我的目录没有写权限。

是来自Java还是来自Apache的错误？

android – 如何从字节数组上传数据到PHP服务器上传进度？

android – 如何从字节数组上传数据到PHP服务器上传进度？

我通过将文件转换为字节数组,将图像文件从设备上传到 PHP服务器.我在我的应用程序中使用android-async-http-1.3.1.jar将文件上传到服务器.

http://loopj.com/android-async-http/

我想要的是在进度条上显示已上载字节数组的字节数.现在,问题是,如何在上传进行过程中了解已上传的字节数.需要有关想法/示例/代码问题的帮助.先谢谢你们.

解决方法

最后,我做到了.我在AsyncTask类中使用file-input / output-stream完成了这个.下面,我已经给出了上传文件和代码的代码.显示正在进行中……

android-将图片从SDCard上传到FaceBook

android-将图片从SDCard上传到FaceBook

借助Android 2.1,如何将图像上传到Facebook墙？图像存储在SDCard中.

解决方法:

您应该使用Facebook API http://developers.facebook.com/docs/guides/mobile/#android.
然后使用以下代码：

 byte[] data = null;
 try {
     FileInputStream fis = new FileInputStream(PATH_TO_FILE);
     Bitmap bi = BitmapFactory.decodeStream(fis);
     ByteArrayOutputStream baos = new ByteArrayOutputStream();
     bi.compress(Bitmap.CompressFormat.JPEG, 100, baos);
     data = baos.toByteArray();  
  } catch (FileNotFoundException e) { 
     e.printstacktrace();
     Log.d("onCreate", "debug error  e = " + e.toString());
  }     

     Bundle params = new Bundle(); 
     params.putString("method", "photos.upload");  
     params.putByteArray("picture", data);

     Facebook facebook = new Facebook(FACEBOOK_APP_ID);
     AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(facebook);
     mAsyncRunner.request(null, params, "POST", new RequestListener() {

        public void onMalformedURLException(MalformedURLException e, Object state) {
            Log.d("request RequestListener", "debug onMalformedURLException");
        }

        public void onIOException(IOException e, Object state) {
            Log.d("request RequestListener", "debug onIOException");
        }

        public void onFileNotFoundException(FileNotFoundException e, Object state) {
            Log.d("request RequestListener", "debug onFileNotFoundException");
        }

        public void onFacebookError(FacebookError e, Object state) {
            Log.d("request RequestListener", "debug onFacebookError");
        }

        public void onComplete(String response, Object state) {
             Log.d("request RequestListener", "debug onComplete");
        }
     }, null);
