Https 请求，Android 中的身份验证 [英] Https request, authentication in Android

问题描述

我目前正在尝试通过 http Get 调用向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.

I am currently trying to authenticate with a server via a http Get call. The code provided below works when compiled in a java project. Returning the correct token to the program. However whenever I try to implement the same code in Android I do not get a token returned via the Get call.

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

In Android I am returning inputLine in a function, however inputLine is always an empty string.

system.out.println() 打印返回的令牌.

The system.out.println() prints the returned token.

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();
    }
 }
}

感谢您的帮助！！！

推荐答案

我使用 POST 和 FormEntity 从服务器检索数据(例如身份验证)，我从来没有遇到任何问题:

I'm using POST and FormEntity for retrieving data from the server (such as authentication), and i have never had any problems:

final String httpsURL = "https://the url";
final DefaultHttpClient client = new DefaultHttpClient();
final HttpPost httppost = new HttpPost(httpsURL);

//authentication block:
final List<BasicNameValuePair> nvps = new ArrayList<BasicNameValuePair>();
nvps.add(new BasicNameValuePair("userName", userName));
nvps.add(new BasicNameValuePair("password", password));
final UrlEncodedFormEntity p_entity = new UrlEncodedFormEntity(nvps, HTTP.UTF_8);
httppost.setEntity(p_entity);

//sending the request and retrieving the response:
HttpResponse response = client.execute(httppost);
HttpEntity responseEntity = response.getEntity();

//handling the response: responseEntity.getContent() is your InputStream
final InputSource inputSource = new InputSource(responseEntity.getContent());
[...]
