Question

我需要在5.0版本之前的设备上启用TLS 1.2。我实现了TLSSocketFactory：

public class TLSSocketFactory : SSLSocketFactory
{
......
}

TlSSocketFactory implementation

我实现了AndroidCustomClientHandler

AndroidCustomClientHandler

我对服务器的请求是：

_client.SendAsync(aRequest, cancellationToken.Token);

aRequest是HttpRequestMessage的类型。

我收到一个例外：

Javax.Net.Ssl.SSLHandshakeException: 
java.security.cert.CertPathValidatorException: Trust anchor for ` . 
certification path not found. --->` 
Java.Security.Cert.CertificateException: 
java.security.cert.CertPathValidatorException: Trust anchor for certification path not found. ---> Java.Security.Cert.CertPathValidatorException: Trust anchor for certification path not found.
