最近发布了一个关于HttpClient over Https的问题(在这里找到)。我取得了一些进展,但我遇到了新的问题。就像我的最后一个问题一样,我似乎找不到一个适合我的例子。基本上,我希望我的客户端接受任何证书(因为我只指向一个服务器),但我总是得到一个javax.net.ssl.SSLException:不受信任的服务器证书异常。

这就是我得到的:


    public void connect() throws A_WHOLE_BUNCH_OF_EXCEPTIONS {

        HttpPost post = new HttpPost(new URI(PROD_URL));
        post.setEntity(new StringEntity(BODY));

        KeyStore trusted = KeyStore.getInstance("BKS");
        trusted.load(null, "".toCharArray());
        SSLSocketFactory sslf = new SSLSocketFactory(trusted);
        sslf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

        SchemeRegistry schemeRegistry = new SchemeRegistry();
        schemeRegistry.register(new Scheme ("https", sslf, 443));
        SingleClientConnManager cm = new SingleClientConnManager(post.getParams(),
                schemeRegistry);

        HttpClient client = new DefaultHttpClient(cm, post.getParams());
        HttpResponse result = client.execute(post);
    }

这是我得到的错误:

将这段代码添加到HttpsURLConnection之前,它就会完成。我明白了。

private void trustEveryone() { 
    try { 
            HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier(){ 
                    public boolean verify(String hostname, SSLSession session) { 
                            return true; 
                    }}); 
            SSLContext context = SSLContext.getInstance("TLS"); 
            context.init(null, new X509TrustManager[]{new X509TrustManager(){ 
                    public void checkClientTrusted(X509Certificate[] chain, 
                                    String authType) throws CertificateException {} 
                    public void checkServerTrusted(X509Certificate[] chain, 
                                    String authType) throws CertificateException {} 
                    public X509Certificate[] getAcceptedIssuers() { 
                            return new X509Certificate[0]; 
                    }}}, new SecureRandom()); 
            HttpsURLConnection.setDefaultSSLSocketFactory( 
                            context.getSocketFactory());

其他回答

你基本上有四个潜在的解决方案来修复Android上使用httpclient的“不受信任”异常:

Trust all certificates. Don't do this, unless you really know what you're doing. Create a custom SSLSocketFactory that trusts only your certificate. This works as long as you know exactly which servers you're going to connect to, but as soon as you need to connect to a new server with a different SSL certificate, you'll need to update your app. Create a keystore file that contains Android's "master list" of certificates, then add your own. If any of those certs expire down the road, you are responsible for updating them in your app. I can't think of a reason to do this. Create a custom SSLSocketFactory that uses the built-in certificate KeyStore, but falls back on an alternate KeyStore for anything that fails to verify with the default.

这个答案使用了解决方案#4,在我看来这是最健壮的。

解决方案是使用可以接受多个KeyStore的SSLSocketFactory,允许您使用自己的证书提供自己的KeyStore。这允许你加载额外的顶级证书,比如Thawte,这可能在一些Android设备上是缺失的。它还允许您加载自己的自签名证书。它将首先使用内置的默认设备证书,只在必要时使用您的附加证书。

首先,您需要确定KeyStore中缺少哪个证书。执行如下命令:

openssl s_client -connect www.yourserver.com:443

你会看到如下输出:

Certificate chain
 0 s:/O=www.yourserver.com/OU=Go to 
   https://www.thawte.com/repository/index.html/OU=Thawte SSL123 
   certificate/OU=Domain Validated/CN=www.yourserver.com
   i:/C=US/O=Thawte, Inc./OU=Domain Validated SSL/CN=Thawte DV SSL CA
 1 s:/C=US/O=Thawte, Inc./OU=Domain Validated SSL/CN=Thawte DV SSL CA
   i:/C=US/O=thawte, Inc./OU=Certification Services Division/OU=(c) 
   2006 thawte, Inc. - For authorized use only/CN=thawte Primary Root CA

如您所见,我们的根证书来自Thawte。访问您的提供商的网站并找到相应的证书。对我们来说,它就在这里,你可以看到我们需要的是2006年的版权。

如果您使用的是自签名证书,则不需要执行前面的步骤,因为您已经有了签名证书。

然后,创建一个包含缺少的签名证书的keystore文件。Crazybob详细介绍了如何在Android上做到这一点,但想法是这样的:

如果您还没有,请从http://www.bouncycastle.org/latest_releases.html下载bouncycastle提供程序库。这将在下面的类路径中。

执行命令从服务器端提取证书并生成pem文件。在本例中为mycert.pem。

echo | openssl s_client -connect ${MY_SERVER}:443 2>&1 | \
 sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > mycert.pem

然后运行以下命令创建密钥存储库。

export CLASSPATH=/path/to/bouncycastle/bcprov-jdk15on-155.jar
CERTSTORE=res/raw/mystore.bks
if [ -a $CERTSTORE ]; then
    rm $CERTSTORE || exit 1
fi
keytool \
      -import \
      -v \
      -trustcacerts \
      -alias 0 \
      -file <(openssl x509 -in mycert.pem) \
      -keystore $CERTSTORE \
      -storetype BKS \
      -provider org.bouncycastle.jce.provider.BouncyCastleProvider \
      -providerpath /path/to/bouncycastle/bcprov-jdk15on-155.jar \
      -storepass some-password

你会注意到上面的脚本将结果放在res/raw/mystore.bks中。现在你有一个文件,你将加载到你的Android应用程序,提供缺少的证书。

为此,为SSL方案注册SSLSocketFactory:

final SchemeRegistry schemeRegistry = new SchemeRegistry();
schemeRegistry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
schemeRegistry.register(new Scheme("https", createAdditionalCertsSSLSocketFactory(), 443));

// and then however you create your connection manager, I use ThreadSafeClientConnManager
final HttpParams params = new BasicHttpParams();
...
final ThreadSafeClientConnManager cm = new ThreadSafeClientConnManager(params,schemeRegistry);

创建SSLSocketFactory:

protected org.apache.http.conn.ssl.SSLSocketFactory createAdditionalCertsSSLSocketFactory() {
    try {
        final KeyStore ks = KeyStore.getInstance("BKS");

        // the bks file we generated above
        final InputStream in = context.getResources().openRawResource( R.raw.mystore);  
        try {
            // don't forget to put the password used above in strings.xml/mystore_password
            ks.load(in, context.getString( R.string.mystore_password ).toCharArray());
        } finally {
            in.close();
        }

        return new AdditionalKeyStoresSSLSocketFactory(ks);

    } catch( Exception e ) {
        throw new RuntimeException(e);
    }
}

最后,AdditionalKeyStoresSSLSocketFactory代码,它接受新的KeyStore并检查内置的KeyStore是否无法验证SSL证书:

/**
 * Allows you to trust certificates from additional KeyStores in addition to
 * the default KeyStore
 */
public class AdditionalKeyStoresSSLSocketFactory extends SSLSocketFactory {
    protected SSLContext sslContext = SSLContext.getInstance("TLS");

    public AdditionalKeyStoresSSLSocketFactory(KeyStore keyStore) throws NoSuchAlgorithmException, KeyManagementException, KeyStoreException, UnrecoverableKeyException {
        super(null, null, null, null, null, null);
        sslContext.init(null, new TrustManager[]{new AdditionalKeyStoresTrustManager(keyStore)}, null);
    }

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

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

我从“emmby”(回答6月16 '11 21:29),项目#4:“创建一个自定义SSLSocketFactory,使用内置的证书KeyStore,但对于任何无法用默认值验证的东西,都依赖于另一个KeyStore。”

这是一个简化的实现。加载系统密钥存储库并与应用程序密钥存储库合并。

public HttpClient getNewHttpClient() {
    try {
        InputStream in = null;
        // Load default system keystore
        KeyStore trusted = KeyStore.getInstance(KeyStore.getDefaultType()); 
        try {
            in = new BufferedInputStream(new FileInputStream(System.getProperty("javax.net.ssl.trustStore"))); // Normally: "/system/etc/security/cacerts.bks"
            trusted.load(in, null); // no password is "changeit"
        } finally {
            if (in != null) {
                in.close();
                in = null;
            }
        }

        // Load application keystore & merge with system
        try {
            KeyStore appTrusted = KeyStore.getInstance("BKS"); 
            in = context.getResources().openRawResource(R.raw.mykeystore);
            appTrusted.load(in, null); // no password is "changeit"
            for (Enumeration<String> e = appTrusted.aliases(); e.hasMoreElements();) {
                final String alias = e.nextElement();
                final KeyStore.Entry entry = appTrusted.getEntry(alias, null);
                trusted.setEntry(System.currentTimeMillis() + ":" + alias, entry, null);
            }
        } finally {
            if (in != null) {
                in.close();
                in = null;
            }
        }

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

        SSLSocketFactory sf = new SSLSocketFactory(trusted);
        sf.setHostnameVerifier(SSLSocketFactory.BROWSER_COMPATIBLE_HOSTNAME_VERIFIER);

        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();
    }
}

一个简单的模式,从JKS转换到BKS:

keytool -importkeystore -destkeystore cacerts.bks -deststoretype BKS -providerclass org.bouncycastle.jce.provider.BouncyCastleProvider -providerpath bcprov-jdk16-141.jar -deststorepass changeit -srcstorepass changeit -srckeystore $JAVA_HOME/jre/lib/security/cacerts -srcstoretype JKS -noprompt
