我正在制作一个应用程序，它应该将文件从 sd 卡上传到 php 服务器以进行进一步处理，但是当我尝试上传我的 logcat 时显示以下错误：java.net.ConnectException: failed to connect to /10.0.2.2 (port 8080):连接失败：ETIMEDOUT（连接超时）。我的java代码如下。

package de.smsbackup;

import android.R;
import android.app.Activity;

HttpURLConnection conn;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

        // ------------------ CLIENT REQUEST

        Log.e(Tag, "Inside second Method");

        FileInputStream fileInputStream = new FileInputStream(new File(
                exsistingFileName));

        // open a URL connection to the Servlet

        URL url = new URL(urlString);

        // Open a HTTP connection to the URL

        conn = (HttpURLConnection) url.openConnection();

        conn.setDoOutput(true);

        // Don't use a cached copy.
        conn.setUseCaches(false);

        // Use a post method.

        conn.setRequestProperty("Content-Type",
                "multipart/form-data;boundary=" + boundary);

        DataOutputStream dos = new DataOutputStream(conn.getOutputStream());

        dos.writeBytes(twoHyphens + boundary + lineEnd);
        dos.writeBytes("Content-Disposition: post-data; name=uploadedfile;filename="
                        + exsistingFileName + "" + lineEnd);
        dos.writeBytes(lineEnd);

        Log.e(Tag, "Headers are written");

        // create a buffer of maximum size

        int bytesAvailable = fileInputStream.available();
        int maxBufferSize = 1000;
        // int bufferSize = Math.min(bytesAvailable, maxBufferSize);
        byte[] buffer = new byte[bytesAvailable];

        // read file and write it into form...

        int bytesRead = fileInputStream.read(buffer, 0, bytesAvailable);

        while (bytesRead > 0) {
            dos.write(buffer, 0, bytesAvailable);
            bytesAvailable = fileInputStream.available();
            bytesAvailable = Math.min(bytesAvailable, maxBufferSize);
            bytesRead = fileInputStream.read(buffer, 0, bytesAvailable);
        }

        // send multipart form data necesssary after file data...

        dos.writeBytes(lineEnd);
        dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);

        // close streams
        Log.e(Tag, "File is written");
        fileInputStream.close();
        dos.flush();
        dos.close();

    } catch (MalformedURLException ex) {
        Log.e(Tag, "error: " + ex.getMessage(), ex);
    }

    catch (IOException ioe) {
        Log.e(Tag, "error: " + ioe.getMessage(), ioe);
    }


    try {
        BufferedReader rd = new BufferedReader(new InputStreamReader(conn
                .getInputStream()));
        String line;
        while ((line = rd.readLine()) != null) {
            Log.e("Dialoge Box", "Message: " + line);
        }
        rd.close();

    } catch (IOException ioex) {
        Log.e("Note Pad", "error: " + ioex.getMessage(), ioex);
    }
}
}

我的PHP文件如下：

<?php
// Where the file is going to be placed 
 $target_path = "admin/";

 /* Add the original filename to our target path.  
  Result is "uploads/filename.extension" */
 $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";
  chmod ("uploads/".basename( $_FILES['uploadedfile']['name']), 0644);
} else{
 echo "There was an error uploading the file, please try again!";
 echo "filename: " .  basename( $_FILES['uploadedfile']['name']);
 echo "target_path: " .$target_path;
}
?>

请任何人尽快告诉我我错在哪里？谢谢。

我认为这是因为您处理 IP。尝试使用域名。
