新浪微博请求数据出错（Android Volley Https证书不信任）的解决方案
邢华清
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：
com.android.volley.NoConnectionError: javax.net.ssl.SSLHandshakeException: org.bouncycastle.jce.exception.ExtCertPathValidatorException: Could not validate certificate signature.

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。
如果大家觉得对自己有帮助的话，还希望能帮顶一下，谢谢：）
