Android Volley增加Https支持，允许SSL

转自：http://m.blog.csdn.net/article/details?id=50497027，在此记录

Volley默认是不支持Https请求的。如果Https服务器是单向认证，则增加以下允许SSL就可以。

先增加SsX509TrustManager类，代码如下

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;

/**
* Volley允许HTTPS

public class SsX509TrustManager 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;
}

/**
* 允许所有的SSL请求，添加在new StringRequest()之前
*/
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 SsX509TrustManager()};
}

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());
}

}

然后再new StringRequest()之前加上下面这句代码就可以了
SsX509TrustManager.allowAllSSL();
