HTTPS 连接安卓

Question

我正在做一个 https 帖子，但我收到了 ssl 异常不受信任的服务器证书的异常。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

这就是我正在做的。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

我在猜测，但如果您希望发生真正的握手，您必须让 android 知道您的证书。如果您无论如何都想接受，请使用此伪代码通过 Apache HTTP 客户端获取您需要的内容：

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，获取示例 here。

祝你好运！

*这不是我写的，但感谢 Bob Lee 的工作

Answer 4

你也可以看看我的博客文章，很像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。

礼貌马杜兰加

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 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，告诉您“对等方未通过身份验证”。尽管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。 此方案解决了“peer not authenticated”导致的异常。

但是在我们讨论解决方案之前，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您确信这不会造成任何问题，否则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。

首先你必须创建一个扩展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();
     }
}

然后你可以创建HttpClient。

HttpClient httpclient = getNewHttpClient();

如果您尝试向登录页面发送发布请求，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 页面获取到 InputStream。然后你可以对返回的 html 页面做任何你想做的事情。

但是在这里你会遇到一个问题。如果您想使用 cookie 管理会话，您将无法使用此方法进行操作。如果您想获取 cookie，则必须通过浏览器进行。那么只有你会收到 cookie。

Answer 6

如果您使用的是 StartSSL 或 Thawte 证书，则对于 Froyo 和旧版本将失败。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 也会加剧）。最终我用Self-signed SSL acceptance on Android 和Custom SSL handling stopped working on Android 2.2 FroYo 修复了它

Answer 8

这些答案中的任何一个都不适合我，所以这里是信任任何证书的代码。

我不了解 ssl 证书的 Android 细节，但 Android 不会立即接受自签名 ssl 证书是有道理的。我从 android 论坛上找到了这篇文章，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。我在这个问题上苦苦挣扎了一个星期，直到遇到以下问题，它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

由于某种原因，上面提到的 httpClient 解决方案对我不起作用。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。您可以在以下线程上看到完整的自定义类和实现： http://blog.syedgakbar.com/2012/07/21/android-https-and-not-trusted-server-certificate-error/

帮助我在我的 AWS Apache 服务器上使用我的自签名证书并从 android 设备连接到 HttpsURLConnection 的来源：

SSL on aws instance - 关于 ssl 的亚马逊教程
Android Security with HTTPS and SSL - 创建您自己的客户端信任管理器，用于接受您的证书
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 \
  2048

# 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 \
  -out all/csr.pem \
  -subj "/C=US/ST=Utah/L=Provo/O=ACME Tech Inc/CN=${FQDN}"

# Sign the request from Device with your Root CA
openssl x509 \
  -req -in all/csr.pem \
  -CA all/my-private-root-ca.cert.pem \
  -CAkey all/my-private-root-ca.privkey.pem \
  -CAcreateserial \
  -out all/cert.pem \
  -days 500

# Put things in their proper place
rsync -a all/{privkey,cert}.pem server/
cat all/cert.pem > server/fullchain.pem         # we have no intermediates in this case
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适当的位置（您可以在 /etc/httpd/conf.d/ssl.conf 中找到配置）。所有这些都应该设置：
   SSL证书文件
   SSLCertificateKeyFile
   SSL证书链文件
   SSLCACertificateFile

3. 使用 sudo service httpd restart 重新启动 httpd 并确保 httpd 已启动：
   停止 httpd：[确定]
   启动 httpd：[确定]

4. 复制my-private-root-ca.cert到你的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); } 最后 { 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. 并使用 HttpsURLConnection 建立连接：

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

7. 就是这样，试试你的 https 连接。

    sec.setTrustAll(true);

    org.eclipse.jetty.websocket.client.WebSocketClient client = new WebSocketClient(sec);

Answer 15

只需将此方法用作您的 HTTPClient：

public static  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();
    }
}
