Android Https证书过期的解决方案

应该有很多小伙伴遇到这样一个问题,在线上已发布的app里,关于https的cer证书过期,从而导致app所有网络请求失效无法使用。

这个时候有人就要说了,应急发布一个已更新最新cer证书的apk不就完事了么,其实没那么简单,iOS还好可以通过appstore提供的api查询到新版本,但android就不一样了,需要调用自己Server端提供的api接口查询到新版本,并获取apk下载路径,问题是https都不能访问了,如何请求到版本信息呢?下面提供两种常见的解决方案:

方案一

将版本信息接口让后台改成http(不推荐,后台因素不可控),或者将本地https的设置一个不安全校验(推荐)。

private static OkHttpClient newOkHttpClient(int timeout){

HttpLoggingInterceptor logging = new HttpLoggingInterceptor();

logging.setLevel(HttpLoggingInterceptor.Level.BODY);

return new OkHttpClient.Builder()

.addInterceptor(new RequestInfoInterceptor())

//.addInterceptor(logging)

.addNetworkInterceptor(new TokenHeaderInterceptor())

.sslSocketFactory(Certificate.getSSLSocketFactory())

//设置不安全校验

.hostnameVerifier(Certificate.getUnSafeHostnameVerifier())

.readTimeout(timeout, TimeUnit.SECONDS)

.writeTimeout(timeout, TimeUnit.SECONDS)

.build();

}

/**

*获取HostnameVerifier

*/

public static HostnameVerifier getUnSafeHostnameVerifier() {

HostnameVerifier hostnameVerifier = new HostnameVerifier() {

@Override

public boolean verify(String s, SSLSession sslSession) {

return true;

}

};

return hostnameVerifier;

}

方案二

将xxx.cer证书改成动态读取(以文件的方式从app沙盒里面读取即可),在https证书即将过期时,从服务器下载最新的cer证书更新到沙盒里面,App每次初始化网络请求时读取sdcard最新的证书文件,这样App就永远不会出现https证书过期导致无法使用的问题,流程图如下。

下面是一些关键的代码:

private static OkHttpClient newOkHttpClient(int timeout){

HttpLoggingInterceptor logging = new HttpLoggingInterceptor();

logging.setLevel(HttpLoggingInterceptor.Level.BODY);

return new OkHttpClient.Builder()

.addInterceptor(new RequestInfoInterceptor())

//.addInterceptor(logging)

.addNetworkInterceptor(new TokenHeaderInterceptor())

.sslSocketFactory(Certificate.getSSLSocketFactory(BaseApplcation.myApp, new String[]{"/sdcard/xxx.cer"}))

.hostnameVerifier(Certificate.getUnSafeHostnameVerifier())

.readTimeout(timeout, TimeUnit.SECONDS)

.writeTimeout(timeout, TimeUnit.SECONDS)

.build();

}

/**

* 带证书的,从本地文件读取

* @param context

* @param certificatesFiles 本地文件(通过下载到本地)

* @return

*/

public static SSLSocketFactory getSSLSocketFactory(Context context, String[] certificatesFiles) {

if (context == null) {

throw new NullPointerException("context == null");

}

CertificateFactory certificateFactory;

try {

certificateFactory = CertificateFactory.getInstance("X.509");

KeyStore keyStore = KeyStore.getInstance(KeyStore.getDefaultType());

keyStore.load(null, null);

for (int i = 0; i < certificatesFiles.length; i++) {

InputStream certificate = new FileInputStream(certificatesFiles[i]);

keyStore.setCertificateEntry(String.valueOf(i), certificateFactory.generateCertificate(certificate));

if (certificate != null) {

certificate.close();

}

}

SSLContext sslContext = SSLContext.getInstance("TLS");

TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());

trustManagerFactory.init(keyStore);

sslContext.init(null, trustManagerFactory.getTrustManagers(), new SecureRandom());

return sslContext.getSocketFactory();

} catch (Exception e) {

}

return null;

}

/**

* 带证书的,从raw资源中读取

* @param context

* @param certificates rawIds

* @return

*/

public static SSLSocketFactory getSSLSocketFactory(Context context, int[] certificates) {

if (context == null) {

throw new NullPointerException("context == null");

}

CertificateFactory certificateFactory;

try {

certificateFactory = CertificateFactory.getInstance("X.509");

KeyStore keyStore = KeyStore.getInstance(KeyStore.getDefaultType());

keyStore.load(null, null);

for (int i = 0; i < certificates.length; i++) {

InputStream certificate = context.getResources().openRawResource(certificates[i]);

keyStore.setCertificateEntry(String.valueOf(i), certificateFactory.generateCertificate(certificate));

if (certificate != null) {

certificate.close();

}

}

SSLContext sslContext = SSLContext.getInstance("TLS");

TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());

trustManagerFactory.init(keyStore);

sslContext.init(null, trustManagerFactory.getTrustManagers(), new SecureRandom());

return sslContext.getSocketFactory();

} catch (Exception e) {

}

return null;

}
