我目前正在尝试通过http Get调用服务器进行身份验证.下面提供的代码在java项目中编译时有效.将正确的令牌返回给程序.但是,每当我尝试在Android中实现相同的代码时,我都不会通过Get调用返回令牌.

在Android中,我在函数中返回inputLine,但inputLine始终是空字符串.

system.out.println()打印返回的标记.

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.URL;
import javax.net.ssl.HttpsURLConnection;

public class JavaHttpsExample 
{

public static void main(String[] args)
{   String inputLine = new String();
    try
    {
    String httpsURL = "https://the url";
    URL myurl = new URL(httpsURL);
    HttpsURLConnection con = (HttpsURLConnection)myurl.openConnection();
    InputStream ins = con.getInputStream();
    InputStreamReader isr=new InputStreamReader(ins);
    BufferedReader in =new BufferedReader(isr);

    inputLine = in.readLine();

    System.out.println(inputLine);

    in.close();


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

谢谢你的帮助！！！
