Question

我尝试将POST数据发送到自己网络上的本地PHP服务器中，并尝试了测试代码。但是由于某种原因该连接被拒绝（即使我的网络还可以），并且我无法将发布数据发送到我的服务器（例如：http://192.168.1.103/bot/post.php）谁能建议我这是什么导致错误？预先感谢！

public class Main2Activity extends Activity {

private static final String TAG = "Main2Activity.java";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main2);

    new PostDataAsyncTask().execute();
}

public class PostDataAsyncTask extends AsyncTask<String, String, String> {
    protected void onPreExecute() {
        super.onPreExecute();
    }

    @Override
    protected String doInBackground(String... strings) {
        try {
            postData();
        } catch (NullPointerException e) {
            e.printStackTrace();
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }

    @Override
    protected void onPostExecute(String lenghtOfFile) {
    }
}

// POST the datas
    private void postData() {
    try {
        String postReceiverUrl = "http://192.168.1.103/bot/post.php";
        Log.v(TAG, "postURL: " + postReceiverUrl);

        HttpClient httpClient = new DefaultHttpClient();
        HttpPost httpPost = new HttpPost(postReceiverUrl);

        List<NameValuePair> nameValuePairs = new  ArrayList<NameValuePair>(2);
        nameValuePairs.add(new BasicNameValuePair("abcd", "1234"));
        nameValuePairs.add(new BasicNameValuePair("asif", "5678"));

        httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

        // execute
        HttpResponse response = httpClient.execute(httpPost);
        HttpEntity resEntity = response.getEntity();

        if (resEntity != null) {
            String responseStr = EntityUtils.toString(resEntity).trim();
            Log.v(TAG, "Response: " + responseStr);
        }

    } catch (ClientProtocolException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
 }}

Answer 1

它在您的堆栈跟踪Caused by: java.net.SocketException: Permission denied中说，这意味着您尚未向清单添加适当的权限，只需将<uses-permission android:name="android.permission.INTERNET" />添加到根AndroidManifest.xml文件中的application标记之前

android中的连接拒绝发送数据
