Https Connection Android

Question

我正在做一个https帖子，我得到ssl异常的例外不可信服务器证书。如果我做正常的http它工作得很好。我必须以某种方式接受服务器证书吗？

Answer 1

这就是我在做的事情。它根本不再检查证书。

// always verify the host - dont check for certificate
final static HostnameVerifier DO_NOT_VERIFY = new HostnameVerifier() {
    public boolean verify(String hostname, SSLSession session) {
        return true;
    }
};

/**
 * Trust every server - dont check for any certificate
 */
private static void trustAllHosts() {
    // Create a trust manager that does not validate certificate chains
    TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {
        public java.security.cert.X509Certificate[] getAcceptedIssuers() {
            return new java.security.cert.X509Certificate[] {};
        }

        public void checkClientTrusted(X509Certificate[] chain,
                String authType) throws CertificateException {
        }

        public void checkServerTrusted(X509Certificate[] chain,
                String authType) throws CertificateException {
        }
    } };

    // Install the all-trusting trust manager
    try {
        SSLContext sc = SSLContext.getInstance("TLS");
        sc.init(null, trustAllCerts, new java.security.SecureRandom());
        HttpsURLConnection
                .setDefaultSSLSocketFactory(sc.getSocketFactory());
    } catch (Exception e) {
        e.printStackTrace();
    }
}

和

    HttpURLConnection http = null;

    if (url.getProtocol().toLowerCase().equals("https")) {
        trustAllHosts();
        HttpsURLConnection https = (HttpsURLConnection) url.openConnection();
        https.setHostnameVerifier(DO_NOT_VERIFY);
        http = https;
    } else {
        http = (HttpURLConnection) url.openConnection();
    }

Answer 2

我正在猜测，但如果你想要进行实际的握手，你必须让android知道你的证书。如果你想接受无论什么，那么使用这个伪代码来获得你需要的Apache HTTP客户端：

SchemeRegistry schemeRegistry = new SchemeRegistry ();

schemeRegistry.register (new Scheme ("http",
    PlainSocketFactory.getSocketFactory (), 80));
schemeRegistry.register (new Scheme ("https",
    new CustomSSLSocketFactory (), 443));

ThreadSafeClientConnManager cm = new ThreadSafeClientConnManager (
    params, schemeRegistry);


return new DefaultHttpClient (cm, params);

CustomSSLSocketFactory：

public class CustomSSLSocketFactory extends org.apache.http.conn.ssl.SSLSocketFactory
{
private SSLSocketFactory FACTORY = HttpsURLConnection.getDefaultSSLSocketFactory ();

public CustomSSLSocketFactory ()
    {
    super(null);
    try
        {
        SSLContext context = SSLContext.getInstance ("TLS");
        TrustManager[] tm = new TrustManager[] { new FullX509TrustManager () };
        context.init (null, tm, new SecureRandom ());

        FACTORY = context.getSocketFactory ();
        }
    catch (Exception e)
        {
        e.printStackTrace();
        }
    }

public Socket createSocket() throws IOException
{
    return FACTORY.createSocket();
}

 // TODO: add other methods like createSocket() and getDefaultCipherSuites().
 // Hint: they all just make a call to member FACTORY 
}

FullX509TrustManager是一个实现javax.net.ssl.X509TrustManager的类，但没有一个方法实际执行任何工作，得到样本here。

祝你好运！

在尝试回答这个问题时，我发现了一个更好的教程。有了它，您不必妥协证书检查。

http://blog.crazybob.org/2010/02/android-trusting-ssl-certificates.html

*我没有写这个，但感谢Bob Lee的工作

Answer 4

您还可以查看我的博客文章，非常类似于crazybobs。

此解决方案也不会影响证书检查，并说明如何在您自己的密钥库中添加受信任的证书。

http://madurangasblogs.blogspot.in/2013/08/avoiding-javaxnetsslsslpeerunverifiedex.html

礼貌Maduranga

在开发使用https的应用程序时，您的测试服务器没有有效的SSL证书。或者有时网站使用自签名证书或网站使用免费的SSL证书。因此，如果您尝试使用Apache HttpClient连接到服务器，您将收到一个异常，告知＆＃34; peer未经过身份验证＆＃34;。虽然信任生产软件中的所有证书并不是一个好习惯，但您可能必须根据情况这样做。 此解决方案解决了由＃34; peer未经过身份验证引起的异常＆＃34;。

但在我们进入解决方案之前，我必须警告您，这对于生产应用程序来说不是一个好主意。这将违反使用安全证书的目的。因此，除非您有充分的理由，或者如果您确定这不会导致任何问题，请不要使用此解决方案。

通常你会像这样创建一个HttpClient。

HttpClient httpclient = new DefaultHttpClient();

但是你必须改变你创建HttpClient的方式。

首先，您必须创建一个扩展org.apache.http.conn.ssl.SSLSocketFactory的类。

import org.apache.http.conn.ssl.SSLSocketFactory;
import java.io.IOException;
import java.net.Socket;
import java.net.UnknownHostException;
import java.security.KeyManagementException;
import java.security.KeyStore;
import java.security.KeyStoreException;
import java.security.NoSuchAlgorithmException;
import java.security.UnrecoverableKeyException;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;

import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;

public class MySSLSocketFactory extends SSLSocketFactory {
         SSLContext sslContext = SSLContext.getInstance("TLS");

    public MySSLSocketFactory(KeyStore truststore) throws NoSuchAlgorithmException, KeyManagementException, KeyStoreException, UnrecoverableKeyException {
        super(truststore);

        TrustManager tm = new X509TrustManager() {
            public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
            }

            public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
            }

            public X509Certificate[] getAcceptedIssuers() {
                return null;
            }
        };

        sslContext.init(null, new TrustManager[] { tm }, null);
    }

    @Override
    public Socket createSocket(Socket socket, String host, int port, boolean autoClose) throws IOException, UnknownHostException {
        return sslContext.getSocketFactory().createSocket(socket, host, port, autoClose);
    }

    @Override
    public Socket createSocket() throws IOException {
        return sslContext.getSocketFactory().createSocket();
    }
}

然后创建一个这样的方法。

public HttpClient getNewHttpClient() {
     try {
         KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
         trustStore.load(null, null);

         SSLSocketFactory sf = new MySSLSocketFactory(trustStore);
         sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

         HttpParams params = new BasicHttpParams();
         HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
         HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);

         SchemeRegistry registry = new SchemeRegistry();
         registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
         registry.register(new Scheme("https", sf, 443));

         ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);

         return new DefaultHttpClient(ccm, params);
     } catch (Exception e) {
         return new DefaultHttpClient();
     }
}

然后您可以创建HttpClient。

HttpClient httpclient = getNewHttpClient();

如果您尝试将帖子请求发送到登录页面，则其余代码将如下所示。

private URI url = new URI("url of the action of the form");
HttpPost httppost =  new HttpPost(url);
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();  
nameValuePairs.add(new BasicNameValuePair("username", "user"));  
nameValuePairs.add(new BasicNameValuePair("password", "password"));
try {
    httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
    HttpResponse response = httpclient.execute(httppost);
    HttpEntity entity = response.getEntity();
    InputStream is = entity.getContent();
} catch (UnsupportedEncodingException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (ClientProtocolException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

您将html页面输入到InputStream。然后你可以用返回的html页面做任何你想做的事。

但在这里你会遇到一个问题。如果要使用cookie管理会话，则无法使用此方法执行此操作。如果您想获取cookie，则必须通过浏览器进行操作。然后只有你会收到cookies。

Answer 6

如果您使用的是StartSSL或Thawte证书，则对于Froyo和旧版本，它将失败。您可以使用newer version's CAcert repository而不是信任每个证书。

Answer 7

这些都不适合我（Thawte bug也加剧了）。最后，我使用Self-signed SSL acceptance on Android和Custom SSL handling stopped working on Android 2.2 FroYo

修复了此问题

Answer 8

这些答案中的任何一个对我都不起作用，所以这里的代码信任任何证书。

我不知道ssl证书的Android细节，但有意义的是Android不会接受自签名的ssl证书。我从android论坛发现了这篇帖子，似乎解决了同样的问题： http://androidforums.com/android-applications/950-imap-self-signed-ssl-certificates.html

Answer 10

这是Android 2.x的一个已知问题。我一直在努力解决这个问题，直到我遇到以下问题，这不仅提供了问题的良好背景，而且提供了一个没有任何安全漏洞的有效解决方案。

'No peer certificate' error in Android 2.3 but NOT in 4

Answer 11

出于某种原因，上面针对httpClient提到的解决方案对我没有用。最后，我能够通过在实现自定义SSLSocketFactory类时正确覆盖该方法来使其工作。

@Override
public Socket createSocket(Socket socket, String host, int port, boolean autoClose) 
                              throws IOException, UnknownHostException 
    {
    return sslFactory.createSocket(socket, host, port, autoClose);
}

@Override
public Socket createSocket() throws IOException {
    return sslFactory.createSocket();
}

这对我来说是完美的。您可以在以下线程中看到完整的自定义类并实现： http://blog.syedgakbar.com/2012/07/21/android-https-and-not-trusted-server-certificate-error/

帮助我在AWS Apache服务器上使用自签名证书并从Android设备连接HttpsURLConnection的来源：

SSL on aws instance - 关于ssl的亚马逊教程 Android Security with HTTPS and SSL - 在客户端创建自己的信任经理，以接受您的证书 Creating self signed certificate - 用于创建证书的简单脚本

然后我做了以下事情：

1. 确保服务器支持https（sudo yum install -y mod24_ssl）
2. 将此脚本放入文件create_my_certs.sh：

#!/bin/bash
FQDN=$1

# make directories to work from
mkdir -p server/ client/ all/

# Create your very own Root Certificate Authority
openssl genrsa \
  -out all/my-private-root-ca.privkey.pem \

# Self-sign your Root Certificate Authority
# Since this is private, the details can be as bogus as you like
openssl req \
  -x509 \
  -new \
  -nodes \
  -key all/my-private-root-ca.privkey.pem \
  -days 1024 \
  -out all/my-private-root-ca.cert.pem \
  -subj "/C=US/ST=Utah/L=Provo/O=ACME Signing Authority Inc/CN=example.com"

# Create a Device Certificate for each domain,
# such as example.com, *.example.com, awesome.example.com
# NOTE: You MUST match CN to the domain name or ip address you want to use
openssl genrsa \
  -out all/privkey.pem \
  2048

# Create a request from your Device, which your Root CA will sign
openssl req -new \
  -key all/privkey.pem \

rsync -a all/my-private-root-ca.cert.pem server/
rsync -a all/my-private-root-ca.cert.pem client/

1. 运行bash create_my_certs.sh yourdomain.com

2. 将证书放在服务器上的适当位置（您可以在/etc/httpd/conf.d/ssl.conf中找到配置）。所有这些都应该设置：
   了SSLCertificateFile
   了SSLCertificateKeyFile
   SSLCertificateChainFile
   SSLCACertificateFile

3. 使用sudo service httpd restart重启httpd并确保启动httpd：
   停止httpd：[确定]
   启动httpd：[确定]

4. 将my-private-root-ca.cert复制到您的android项目资产文件夹

5. 创建您的信任经理：

   SSLContext SSLContext;

   CertificateFactory cf = CertificateFactory.getInstance（“X.509”）;           InputStream caInput = context.getAssets（）。open（“my-private-root-ca.cert.pem”）;           证书ca;           尝试{             ca = cf.generateCertificate（caInput）;           } finally {             caInput.close（）;           }

     // Create a KeyStore containing our trusted CAs
     String keyStoreType = KeyStore.getDefaultType();
     KeyStore keyStore = KeyStore.getInstance(keyStoreType);
     keyStore.load(null, null);
     keyStore.setCertificateEntry("ca", ca);
   
     // Create a TrustManager that trusts the CAs in our KeyStore
     String tmfAlgorithm = TrustManagerFactory.getDefaultAlgorithm();
     TrustManagerFactory tmf = TrustManagerFactory.getInstance(tmfAlgorithm);
     tmf.init(keyStore);
   
     // Create an SSLContext that uses our TrustManager
     SSLContext = SSLContext.getInstance("TLS");
     SSSLContext.init(null, tmf.getTrustManagers(), null);
   

6. 使用HttpsURLConnection建立连接：

   HttpsURLConnection connection =（HttpsURLConnection）url.openConnection（）; connection.setSSLSocketFactory（SSLContext.getSocketFactory（））;

7. 多数，尝试你的https连接。

        trustStore.load(null, null);

        SSLSocketFactory sf = new MySSLSocketFactory(trustStore);
        sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

        HttpParams params = new BasicHttpParams();
        HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
        HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);

        SchemeRegistry registry = new SchemeRegistry();
        registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
        registry.register(new Scheme("https", sf, 443));

        ClientConnectionManager ccm = new ThreadSafeClientConnManager(params, registry);

        return new DefaultHttpClient(ccm, params);
    } catch (Exception e) {
        return new DefaultHttpClient();
    }
}
