Question

此问题可能已经提出过，但针对不同的问题。以下cURL命令可以正常使用shell命令：

curl -u MyuserName:MyPassword  http://192.168.0.198:8067/startvideo?force=1&tag=20141010-121420

我尝试在Java / Android中实现它：

    private void startRecord() {


    HttpClient httpClient = new DefaultHttpClient();
                            // replace with your url
    HttpPost httpPost = new HttpPost("http://192.168.0.198:8067/startvideo?force=1&tag=20141010-121420");


    //Post Data
    List<NameValuePair> nameValuePair = new ArrayList<NameValuePair>(2);
    nameValuePair.add(new BasicNameValuePair("username", "MyuserName"));
    nameValuePair.add(new BasicNameValuePair("password", "MyPassword"));


    //Encoding POST data
    try {
        httpPost.setEntity(new UrlEncodedFormEntity(nameValuePair));
    } catch (UnsupportedEncodingException e) {
        // log exception
        e.printStackTrace();
    }

    //making POST request.
    try {
        HttpResponse response = httpClient.execute(httpPost);
        // write response to log
        Log.d("Http Post Response:", response.toString());
    } catch (ClientProtocolException e) {
        // Log exception
        e.printStackTrace();
    } catch (IOException e) {
        // Log exception
        e.printStackTrace();
    }

}

但该应用程序崩溃并出现以下错误：
