解决 javax.net.ssl.SSLHandshakeException: java.security.cert.CertPathValidatorException

解决 javax.net.ssl.SSLHandshakeException: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.问题

1. 首先创建一个类继承于此类

import java.security.KeyManagementException;
import java.security.NoSuchAlgorithmException;
import java.security.SecureRandom;
import java.security.cert.X509Certificate;

import javax.net.ssl.HostnameVerifier;
import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSession;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;

public class FakeX509TrustManager implements X509TrustManager {

    private static TrustManager[] trustManagers;
    private static final X509Certificate[] _AcceptedIssuers = new
            X509Certificate[] {};

    @Override
    public void checkClientTrusted(java.security.cert.X509Certificate[] x509Certificates, String s) throws java.security.cert.CertificateException {
        //To change body of implemented methods use File | Settings | File Templates.
    }

    @Override
    public void checkServerTrusted(java.security.cert.X509Certificate[] x509Certificates, String s) throws java.security.cert.CertificateException {
        //To change body of implemented methods use File | Settings | File Templates.
    }

    public boolean isClientTrusted(X509Certificate[] chain) {
        return true;
    }

    public boolean isServerTrusted(X509Certificate[] chain) {
        return true;
    }

    @Override
    public X509Certificate[] getAcceptedIssuers() {
        return _AcceptedIssuers;
    }

    public static void allowAllSSL() {
        HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier() {

            @Override
            public boolean verify(String arg0, SSLSession arg1) {
                // TODO Auto-generated method stub
                return true;
            }

        });

        SSLContext context = null;
        if (trustManagers == null) {
            trustManagers = new TrustManager[] { new FakeX509TrustManager() };
        }

        try {
            context = SSLContext.getInstance("TLS");
            context.init(null, trustManagers, new SecureRandom());
        } catch (NoSuchAlgorithmException e) {
            e.printStackTrace();
        } catch (KeyManagementException e) {
            e.printStackTrace();
        }

        HttpsURLConnection.setDefaultSSLSocketFactory(context.getSocketFactory());
    }

}

2. 在请求网络的时候加上此方法即可使用假的证书跳过检测.

RequestQueue mQueue = Volley.newRequestQueue(MainActivity.this);

FakeX509TrustManager.allowAllSSL();

StringRequest stringRequest = new StringRequest(Request.Method.GET, volleyGetUrl,
        new Response.Listener<String>() {
            @Override
            public void onResponse(String response) {

                try {
                    JSONObject responseObject = new JSONObject(response);
                    JSONObject dataObject = responseObject.optJSONObject("data");
                    String accessToken = dataObject.optString("access_token");

                    AuthorizeManager.getInstance().registerAccessToken(accessToken);

                    String name = Md5Util.md5(appKey + userName);
                    SpUtils.saveToLocal(MainActivity.this, name, "access_token", accessToken);

                    Toast.makeText(MainActivity.this, "授权成功", Toast.LENGTH_SHORT).show();
                } catch (JSONException e) {
                    e.printStackTrace();
                }
            }
        },
