これは私の最初の投稿であり、可能な限り明確になるように最善を尽くします(私の英語は申し訳ありません)。
これが私のトラブルです。retrofit:1.9.0とokhttp:2.7.5を使用してAPI呼び出しを実行しています。サーバープロバイダーがSLLv2およびSSLv3によるセキュリティの問題の原因を無効にするまで、すべては問題ありませんでした(Drown failは最初の3月に見つかりました)。
今、私はプロバイダーに関する情報を確認し、彼は https://www.ssllabs.com/ からcypherを使用したTLSv1(TLS 1.0 TLS_RSA_WITH_3DES_EDE_CBC_SHA No FS)のみを許可しています。
わかりましたので、これは私が行ったすべてのテストと結果です:
[問題の更新を解決]
2番目の答えでこの問題を解決する方法を見つけてください。
[〜#〜] update [〜#〜]問題はgoogle APIバージョンに由来するようです。 API 18でテストすると、すべてが正常に機能しています。 Android 5.0.0以上の場合、失敗します。
構成要約:

private static final String BASE_URL = "";
private LoginApiService apiService;
public LoginRestClient()

.setDateFormat("yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'SSS'Z'")
.create();
RestAdapter restAdapter = new RestAdapter.Builder()
.setLogLevel(RestAdapter.LogLevel.FULL)
.setEndpoint(ApiIntentService.getHostAddress())
.setConverter(new GsonConverter(gson))
.setClient(new OkClient(ApiIntentService.getConnectionHttpClient()))
.build();
apiService = restAdapter.create(LoginApiService.class);
}
public LoginApiService getApiService() {
return apiService;

カスタムCallBackからのパブリックvoid failure(RetrofitErrorエラー)の結果
Java.net.UnknownServiceException:受け入れ可能なプロトコルが見つかりません。 isFallback = false、modes = [ConnectionSpec(cipherSuites = [TLS_RSA_WITH_3DES_EDE_CBC_SHA]、tlsVersions = [TLS_1_0]、supportsTlsExtensions = true)]、サポートされているプロトコル= [SSLv3、TLSv1、TLSv1.1、TLSv1.2]
SSLv3を無効にしてTLSを強制するカスタムSSLSocketFactoryを作成しました。

こんにちは、ここ3日間と3日間の戦いの後の最後の解決策です。ここのソリューションのおかげで:
Android for HttpsUrlConnection?)でSSLv3を無効にする方法
このライブラリ: https://guardianproject.info/code/netcipher
SSLv2とSSlv3が無効になっている場合に、Androidに暗号とTLSを使用するより良い方法を提供できます。
最初にこのクラスNoSSLv3SocketFactory.Javaを作成し、次のようなコンストラクターを作成してこれをCypherUrl接続と結合します

そして今(私の場合はレトロフィットで)次のように使用します:
最初に、静的メソッドを追加し(または使用時に作成したい場合)、以前に作成したNoSSlv3Factory.JavaクラスでokHttpClientを作成します。
public static OkClient createClient(int readTimeout, TimeUnit readTimeoutUnit, int connectTimeout, TimeUnit connectTimeoutUnit)
{
final OkHttpClient okHttpClient = new OkHttpClient();
okHttpClient.setReadTimeout(readTimeout, readTimeoutUnit);
okHttpClient.setConnectTimeout(connectTimeout, connectTimeoutUnit);
try {
URL url = new URL(ApiIntentService.getHostAddress());
SSLSocketFactory NoSSLv3Factory = new NoSSLv3SocketFactory(url);
okHttpClient.setSslSocketFactory(NoSSLv3Factory);
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return new OkClient(okHttpClient);
}
次に、、私の場合、RestAdapterを作成するときは、このようにして、クライアントを設定することを忘れないでください。
public class LoginRestClient
{
private static final String BASE_URL = "";
private LoginApiService apiService;
public LoginRestClient()
{
Gson gson = new GsonBuilder()
.setDateFormat("yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'SSS'Z'")
.create();
RestAdapter restAdapter = new RestAdapter.Builder()
.setLogLevel(RestAdapter.LogLevel.FULL)
.setEndpoint(ApiIntentService.getHostAddress())
.setConverter(new GsonConverter(gson))
.setClient(ApiIntentService.createClient(60, TimeUnit.SECONDS, 20, TimeUnit.SECONDS))
.build();
apiService = restAdapter.create(LoginApiService.class);
}
public LoginApiService getApiService() {
return apiService;
}
}
これで動作するはずです。私はそれが他の誰かに役立つことを願っています。
私はここで解決策を見つけました このリンク 。
Androidアプリケーションクラスのコードの下に配置するだけです。それで十分です。Retrofit設定を変更する必要はありません。
public class MyApplication extends Application {
@Override
public void onCreate() {
super.onCreate();
try {
// Google Play will install latest OpenSSL
ProviderInstaller.installIfNeeded(getApplicationContext());
SSLContext sslContext;
sslContext = SSLContext.getInstance("TLSv1.2");
sslContext.init(null, null, null);
sslContext.createSSLEngine();
} catch (GooglePlayServicesRepairableException | GooglePlayServicesNotAvailableException
| NoSuchAlgorithmException | KeyManagementException e) {
e.printStackTrace();
}
}
}
これが助けになることを願っています。ありがとうございました。
