使用所有HTTPS

httpClient = new DefaultHttpClient();

SSLContext ctx = SSLContext.getInstance("TLS");
X509TrustManager tm = new X509TrustManager() {
    public void checkClientTrusted(X509Certificate[] xcs, String string) throws CertificateException { }

    public void checkServerTrusted(X509Certificate[] xcs, String string) throws CertificateException { }

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

ctx.init(null, new TrustManager[]{tm}, null);
SSLSocketFactory ssf = new SSLSocketFactory(ctx, SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

httpClient.getConnectionManager().getSchemeRegistry().register(new Scheme("https", 443, ssf));

上面有很多答案，但我不能让他们中的任何一个正确工作(与我有限的时间)，所以对于其他人在相同的情况下，你可以尝试下面的代码，它非常适合我的java测试目的:

    public static HttpClient wrapClient(HttpClient base) {
    try {
        SSLContext ctx = SSLContext.getInstance("TLS");
        X509TrustManager tm = new X509TrustManager() {
            public void checkClientTrusted(X509Certificate[] xcs, String string) throws CertificateException { }

            public void checkServerTrusted(X509Certificate[] xcs, String string) throws CertificateException { }

            public X509Certificate[] getAcceptedIssuers() {
                return null;
            }
        };
        ctx.init(null, new TrustManager[]{tm}, null);
        SSLSocketFactory ssf = new SSLSocketFactory(ctx);
        ssf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
        ClientConnectionManager ccm = base.getConnectionManager();
        SchemeRegistry sr = ccm.getSchemeRegistry();
        sr.register(new Scheme("https", ssf, 443));
        return new DefaultHttpClient(ccm, base.getParams());
    } catch (Exception ex) {
        return null;
    }
}

像这样叫:

DefaultHttpClient baseClient = new DefaultHttpClient();
HttpClient httpClient = wrapClient(baseClient );

参考:http://tech.chitgoks.com/2011/04/24/how-to-avoid-javax-net-ssl-sslpeerunverifiedexception-peer-not-authenticated-problem-using-apache-httpclient/

下面是一个使用4.1.2 httpclient代码的简单版本。然后可以将其修改为您认为合适的任何信任算法。

public static HttpClient getTestHttpClient() {
    try {
        SSLSocketFactory sf = new SSLSocketFactory(new TrustStrategy(){
            @Override
            public boolean isTrusted(X509Certificate[] chain,
                    String authType) throws CertificateException {
                return true;
            }
        });
        SchemeRegistry registry = new SchemeRegistry();
        registry.register(new Scheme("https", 443, sf));
        ClientConnectionManager ccm = new ThreadSafeClientConnManager(registry);
        return new DefaultHttpClient(ccm);
    } catch (Exception e) {
        return new DefaultHttpClient();
    }
}

任何在android2.1上还在为StartCom SSL证书而挣扎的人，请访问https://www.startssl.com/certs/并下载ca.pem，现在在@emmby replace提供的答案中

`export CLASSPATH=bcprov-jdk16-145.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 /usr/share/java/bcprov.jar \
  -storepass some-password`

与

 `export CLASSPATH=bcprov-jdk16-145.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 ca.pem) \
  -keystore $CERTSTORE \
  -storetype BKS \
  -provider org.bouncycastle.jce.provider.BouncyCastleProvider \
  -providerpath /usr/share/java/bcprov.jar \
  -storepass some-password`

应该开箱即用。即使@emmby给出了一个完美的答案，我还是纠结了一天多。希望这能帮助到某人…

自API 8以来，您可以通过这种方式禁用HttpURLConnection SSL检查:

    HttpURLConnection conn = (HttpURLConnection) url.openConnection();
    if (conn instanceof HttpsURLConnection) {
        HttpsURLConnection httpsConn = (HttpsURLConnection) conn;
        httpsConn.setSSLSocketFactory(SSLCertificateSocketFactory.getInsecure(0, null));
        httpsConn.setHostnameVerifier(new AllowAllHostnameVerifier());
    }

信任所有证书对我来说并不是真正的替代方法，所以我做了以下工作来让HttpsURLConnection信任一个新的证书(也请参阅http://nelenkov.blogspot.jp/2011/12/using-custom-certificate-trust-store-on.html)。

Get the certificate; I got this done by exporting the certificate in Firefox (click on the little lock icon, get certificate details, click export), then used portecle to export a truststore (BKS). Load the Truststore from /res/raw/geotrust_cert.bks with the following code: final KeyStore trustStore = KeyStore.getInstance("BKS"); final InputStream in = context.getResources().openRawResource( R.raw.geotrust_cert); trustStore.load(in, null); final TrustManagerFactory tmf = TrustManagerFactory .getInstance(TrustManagerFactory.getDefaultAlgorithm()); tmf.init(trustStore); final SSLContext sslCtx = SSLContext.getInstance("TLS"); sslCtx.init(null, tmf.getTrustManagers(), new java.security.SecureRandom()); HttpsURLConnection.setDefaultSSLSocketFactory(sslCtx .getSocketFactory());
