Question

我的问题是，执行conn.connect();时，我的应用崩溃了。这是我的代码：

package com.example.andrejkovict.myapplication;

import ...

public class MainActivity extends AppCompatActivity
{
    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        String url = "localhost/test.php?tel="+number;
        String ret = HttpGet(url);
        Log.e("tag","http "+ret);
    }


    public String HttpGet(String myUrl) throws IOException
    {
        InputStream inputStream = null;
        String result = "";

        URL url = new URL(myUrl);
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        Log.e("tag","http 1");
        conn.connect();
        Log.e("tag","http 2");
        inputStream = conn.getInputStream();

        if(inputStream != null)
            result = convertInputStreamToString(inputStream);
        else
            result = "Did not work!";
        return result;
    }

    public static String convertInputStreamToString(InputStream inputStream) throws IOException
    {
        BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(inputStream));
        String line = "";
        String result = "";
        while((line = bufferedReader.readLine()) != null) result += line;
        inputStream.close();
        return result;

    }
}

在控制台中，仅输出为：“ http 1”，而不是“ http 2”和“ http返回字符串”

哪里有问题？

感谢您的帮助。

使用下面的代码。

String urlink = "http://localhost/test.php?tel="+number;
     URL url = new URL(link);
                HttpURLConnection conn = (HttpURLConnection) url.openConnection();
                conn.connect();
                InputStream is = conn.getInputStream();
                BufferedReader reader = new BufferedReader(new InputStreamReader(is, "UTF-8"));
                String data = "";
                String webPage="";
                while ((data = reader.readLine()) != null) {
                    webPage += data + "\n";
                }
