新浪微博请求数据出错（Android(安卓)Volley Https证书不信任）的解决方案

今天在调用新浪微博android sdk时出现Https证书不信任的问题，查了很多资料终于解决了，在这里把解决方案分享给大家。

错误如下：

javax.net.ssl.SSLHandshakeException: org.bouncycastle.jce.exception.ExtCertPathValidatorException: Could not validate certificate signature

具体错误如下：

一番谷歌和百度之后，找到了两个很有用的链接：

腾讯微博oauth认证

http请求No peer certificate的解决方法

但是里面提出的解决方案都是针对自己实现HttpClient或者HttpURLConnection的，而我是使用了Google官方提供的Volley，如果要修改源码的话比较麻烦。于是我大胆猜测Volley底层是采用HttpURLConnection实现的，可以在进行StringRequest之前设置一个X509TrustManager。

首先新建一个类FakeX509TrustManager：

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());    }}

然后在进行StringRequest之前设置：

FakeX509TrustManager.allowAllSSL();mStringRequest = new StringRequest(Request.Method.POST,url,getDefaultSuccessListener(),mErrorListener){            @Override            protected Map<String, String> getParams() throws AuthFailureError {                return params;            }};mRequestQueue.add(mStringRequest);

再次运行则发现可以正常获取数据。
