对于那些希望允许所有证书在OAuth上工作(用于测试目的)的人，请遵循以下步骤:

1)下载Android OAuth API源代码:https://github.com/kaeppler/signpost

2)找到CommonsHttpOAuthProvider类

3)修改如下:

public class CommonsHttpOAuthProvider extends AbstractOAuthProvider {

private static final long serialVersionUID = 1L;

private transient HttpClient httpClient;

public CommonsHttpOAuthProvider(String requestTokenEndpointUrl, String accessTokenEndpointUrl,
        String authorizationWebsiteUrl) {
    super(requestTokenEndpointUrl, accessTokenEndpointUrl, authorizationWebsiteUrl);


    //this.httpClient = new DefaultHttpClient();//Version implemented and that throws the famous "javax.net.ssl.SSLException: Not trusted server certificate" if the certificate is not signed with a CA
    this.httpClient = MySSLSocketFactory.getNewHttpClient();//This will work with all certificates (for testing purposes only)
}

上面的“MySSLSocketFactory”是基于已接受的答案。为了让它更简单，下面是完整的类:

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

    return sslContext.getSocketFactory().createSocket(socket, host, port, autoClose);
}

@Override

    return sslContext.getSocketFactory().createSocket();
}



public static HttpClient getNewHttpClient() {

    try {

        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();
    }
}

}

希望这能帮助到一些人。

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());

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));

我用了这个，它适用于我所有的操作系统。

        }

        @Override

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

  -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…
