andorid HTTPS 不需要证书 VolleyEror: com.android.volley.NoConnectionError: javax.net.ssl.SSLHandshakeException: java.security.cert.CertPathValidatorException: Trust anchor for certification path not fou

1.加证书（这里不说）

2.修改代码

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());
}

}

在调用网络前使用

FakeX509TrustManager.allowAllSSL(); //it is dangerous!但是有的时候我们需要这样做！！ //========================StringRequest===================================================== StringRequest httpRequest = new StringRequest(requestMethod, url, new Response.Listener<String>() { @Override public void onResponse(String response) { 。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。
