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 sslContext = SSLContext.getInstance("TLS");

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

    super(truststore);
    TrustManager tm = new X509TrustManager() {

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

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

        @Override
        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();
}



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();
    }
}

}

希望这能帮助到一些人。

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 );

这是个坏主意。信任任何证书仅仅(非常)比不使用SSL好一点点。当你说“我想让我的客户端接受任何证书(因为我只指向一个服务器)”时，你假设这意味着以某种方式指向“一个服务器”是安全的，它不是在公共网络上。

通过信任任何证书，您完全有可能受到中间人攻击。任何人都可以通过与您和终端服务器建立单独的SSL连接来代理您的连接。然后，MITM可以访问您的整个请求和响应。除非您一开始就不需要SSL(您的消息没有任何敏感内容，并且不进行身份验证)，否则您不应该盲目地信任所有证书。

你应该考虑使用keytool将公共证书添加到jks中，并使用它来构建你的套接字工厂，例如:

    KeyStore ks = KeyStore.getInstance("JKS");

    // get user password and file input stream
    char[] password = ("mykspassword")).toCharArray();
    ClassLoader cl = this.getClass().getClassLoader();
    InputStream stream = cl.getResourceAsStream("myjks.jks");
    ks.load(stream, password);
    stream.close();

    SSLContext sc = SSLContext.getInstance("TLS");
    KeyManagerFactory kmf = KeyManagerFactory.getInstance("SunX509");
    TrustManagerFactory tmf = TrustManagerFactory.getInstance("SunX509");

    kmf.init(ks, password);
    tmf.init(ks);

    sc.init(kmf.getKeyManagers(), tmf.getTrustManagers(),null);

    return sc.getSocketFactory();

这需要注意一个警告。证书最终会过期，代码届时将停止工作。通过查看证书，您可以很容易地确定何时会发生这种情况。

我找到了这个解;在你点击HTTPS链接之前，先把这个代码放上去

const SecurityProtocolType Tls12 = (SecurityProtocolType)_Tls12;
ServicePointManager.SecurityProtocol = Tls12;
