Android https 证书信任问题

因为最近公司的open api服务器访问协议换成了https，所以 android 在使用okhttp 走https 访问的时候遇到了证书信任的问题，

在这里把我走过的弯路记下来，一如既往的话不多说，上码：

OkHttpClient   sClient = new OkHttpClient();

// 设置超时时间
sClient.setConnectTimeout(8000, TimeUnit.MILLISECONDS);
sClient.setReadTimeout(8000, TimeUnit.MILLISECONDS);
// 注册拦截器
sClient.interceptors().add(new BaseInterceptor(context));

第一种方式：

sClient.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

运行结果：

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

11-26 11:17:57.264 17106-17268/com.dooioo.addressbook W/System.err: at com.squareup.okhttp.Connection.connectTls(Connection.java:235)

11-26 11:17:57.264 17106-1726

以失败告终！！！！！

经过多处查询后采用

第二种方案：

sClient.setHostnameVerifier(new HostnameVerifier() {
@Override
public boolean verify(String hostname, SSLSession session) {
return true;
}
});

怀着侥幸的心理运行了一下

运行结果：

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

同样还是以失败而告终呢，这下怎么办呢，总不能说部解决吧，只好硬着头皮继续找资料

最终的解决方案：

SSLContext sc = SSLContext.getInstance("SSL");
sc.init(null, new TrustManager[]{new X509TrustManager() {
@Override
public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {

}

@Override
public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {

}

@Override
public X509Certificate[] getAcceptedIssuers() {
return null;
}
}}, new SecureRandom());
sClient.setSslSocketFactory(sc.getSocketFactory());
sClient.setHostnameVerifier(new HostnameVerifier() {
@Override
public boolean verify(String hostname, SSLSession session) {
return true;
}
});

最终解决问题，成功信任所有证书！！！！

当然了，这个最好是用在开发环境上，正式环境的证书信息，最好不要用这种全部信任的方式，不然https 就形同虚设了……
