04-23 17:17:38.435 21599-21956/ D/OkHttp: <-- HTTP FAILED: javax.net.ssl.SSLHandshakeException: javax.net.ssl.SSLProtocolException: SSL handshake aborted: ssl=0x635d8808: Failure in SSL library, usually a protocol error
    error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure (external/openssl/ssl/s23_clnt.c:744 0x5e6c46fd:0x00000000)

Android 较低版本设备 (4.1 - 4.4) 出现 SSL 错误。以前在以下版本中运行良好:

implementation 'com.squareup.okhttp3:okhttp:3.9.1'
implementation 'com.squareup.okhttp3:okhttp-urlconnection:3.9.1'
implementation 'com.squareup.okhttp3:logging-interceptor:3.9.1'

implementation 'com.squareup.retrofit2:retrofit:2.3.0'
implementation 'com.squareup.retrofit2:converter-jackson:2.3.0'
implementation 'com.squareup.retrofit2:adapter-rxjava:2.3.0'

但是在升级这些库之后，事情发生了变化。每次服务调用都会出现 SSL 握手异常。

implementation 'com.squareup.okhttp3:okhttp:3.10.0'
implementation 'com.squareup.okhttp3:okhttp-urlconnection:3.10.0'
implementation 'com.squareup.okhttp3:logging-interceptor:3.10.0'

implementation 'com.squareup.retrofit2:retrofit:2.4.0'
implementation 'com.squareup.retrofit2:converter-jackson:2.4.0'
implementation 'com.squareup.retrofit2:adapter-rxjava:2.4.0'

此外，如果我将这些库降级到以前的版本，它仍然无法正常工作。但是 git checkout 到以前的提交工作正常。毫 headless 绪。

Answer 1

所以我通过将以下内容添加到我的 http 客户端对象来解决它

 ConnectionSpec spec = new ConnectionSpec.Builder(ConnectionSpec.COMPATIBLE_TLS)
            .tlsVersions(TlsVersion.TLS_1_2, TlsVersion.TLS_1_1, TlsVersion.TLS_1_0)
            .cipherSuites(
                    CipherSuite.TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256,
                    CipherSuite.TLS_ECDHE_ECDSA_WITH_CHACHA20_POLY1305_SHA256,
                    CipherSuite.TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA,
                    CipherSuite.TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA)
            .build();

httpClient.connectionSpecs(Collections.singletonList(spec))
