我正在使用Retrofit 2.2.0将图像上传到服务器(使用Java)。使用Android设备(Samsung galaxy S6)API 24(Build:NRD90M.G920FXXU5EQAC),当我尝试发布请求时,此请求因此错误而失败
javax.net.ssl.SSLHandshakeException: Handshake failed
ps:我尝试降级Retrofit 2.1.0并且它运行良好。

我的解决方案是为OkHttpClient添加更多可接受的密码。自API 21起,某些TLS证书已弃用于Android。这可能会有所帮助:
ConnectionSpec spec = new
ConnectionSpec.Builder(ConnectionSpec.MODERN_TLS)
.tlsVersions(TlsVersion.TLS_1_2)
.cipherSuites(
CipherSuite.TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256,
CipherSuite.TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256,
CipherSuite.TLS_DHE_RSA_WITH_AES_128_GCM_SHA256)
.build();
OkHttpClient client = new OkHttpClient.Builder()
.connectionSpecs(Collections.singletonList(spec))
.build();

我用它与2.2.0
创建不验证证书链的信任管理器
final TrustManager[] trustAllCerts = new TrustManager[]{
new X509TrustManager() {
@Override
public void checkClientTrusted(java.security.cert.X509Certificate[] chain, String authType) throws CertificateException {
}
@Override
public void checkServerTrusted(java.security.cert.X509Certificate[] chain, String authType) throws CertificateException {
}
@Override
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return new java.security.cert.X509Certificate[]{};
}
}
};
// Install the all-trusting trust manager
HttpLoggingInterceptor httpLoggingInterceptor = new HttpLoggingInterceptor();
httpLoggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient.Builder client = new OkHttpClient.Builder();
client.interceptors().add(httpLoggingInterceptor);
client.readTimeout(180, TimeUnit.SECONDS);
client.connectTimeout(180, TimeUnit.SECONDS);
KeyStore keyStore = KeyStore.getInstance(KeyStore.getDefaultType());
keyStore.load(null, null);
SSLContext sslContext = SSLContext.getInstance("TLS");
TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
trustManagerFactory.init(keyStore);
KeyManagerFactory keyManagerFactory = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());
keyManagerFactory.init(keyStore, "keystore_pass".toCharArray());
sslContext.init(null, trustAllCerts, new SecureRandom());
client.sslSocketFactory(sslContext.getSocketFactory())
.hostnameVerifier(new HostnameVerifier() {
@Override
public boolean verify(String hostname, SSLSession session) {
return true;
}
});
Gson gson = new GsonBuilder().setLenient().create();
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(Common.BASE_URL)
.addConverterFactory(GsonConverterFactory.create(gson))
.client(client.build())
.build();
serviceApi = retrofit.create(Api.class);
感谢希望这会对你有所帮助。 有时ssl 1.2或更低版本也没有安装在服务器端。
