Question

我在点击按钮输入方法时将一些数据发布到url。但log cat显示host = null

public class MainActivity extends Activity {

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

        }


public void entry(View v)
{
    HttpClient client = new DefaultHttpClient();
    HttpPost post = new HttpPost("www.uthsms.net/index.php?on=sms");


    List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
    nameValuePairs.add(new BasicNameValuePair("country", "91"));
    nameValuePairs.add(new BasicNameValuePair("pakistan", "91"));
    nameValuePairs.add(new BasicNameValuePair("sindh", "8903466567"));
    nameValuePairs.add(new BasicNameValuePair("gateway", "0"));
    nameValuePairs.add(new BasicNameValuePair("hyderabad", "12345"));
    nameValuePairs.add(new BasicNameValuePair("remLen", "135"));
    nameValuePairs.add(new BasicNameValuePair("recaptcha_challenge_field", "03AHJ_VuvO-0yifgUvXaYPdlTF5QBZwKQlo-gQE8FYioRNi3klTtM_MLDnbzuOH8uUFzX1LXVltrZy8kBcTDY176rLVu3M1EvbkF3fQKxQ3t3nBedlshOvNXHZDFCO5I4Sdm4AkIdpQViTRBDzB6pU9OIombEKY6yy7OsY1Faob6Z47pNAaKWqFGc"));
    nameValuePairs.add(new BasicNameValuePair("recaptcha_response_field", "2485842 76"));
    nameValuePairs.add(new BasicNameValuePair("x", "126"));
    nameValuePairs.add(new BasicNameValuePair("y", "31"));
    nameValuePairs.add(new BasicNameValuePair("button", "Send SMS"));
    try {
        post.setEntity(new UrlEncodedFormEntity(nameValuePairs));
    } catch (UnsupportedEncodingException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }


    // Execute HTTP Post Request
    try {
        HttpResponse response = client.execute(post);
        StatusLine statusLine = response.getStatusLine();
        if(statusLine.getStatusCode() == 200) {
            HttpEntity entity = response.getEntity();
            Log.e(null,"entity"+ entity.toString());
        }
    } catch (ClientProtocolException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

}

Answer 1

试试这个：

httpPost post = new HttpPost("http://www.uthsms.net/index.php?on=sms");

如上所述：没有方案（http）没有主机。

此页面上的<form>操作为：

httpPost post = new HttpPost("http://www.uthsms.net/index.php?on=sms-status");

发布数据时无法获得响应？
